Neoliberalism is both a political philosophy and a term used to signify the late-20th-century political reappearance of 19th-century ideas associated with free-market capitalism. The term has multiple, competing definitions, and is often used pejoratively. (Wiki)

Very similar to the circumstances of the Dudley Triangle.

Is there a way to define a debounce timer?

jesus. This reminds me of the Nutty Putty cave incident. Someone was trapped upside down for 27 hours, and you couldn't even make out his final words since it was basically just gurgling.

This means rest in peace.

ONLY NOW YOU FEEL SICK????? YOU JUST BUILT A WALL KEEPING HIM AWAY FOREVER. HE WAS STRUGGLING TO WALK. WHAT DID YOU THINK WOULD HAPPEN

these names are dehumanizing. Fortunato grew still

You drew your weapon at a man chained down and behind a wall?

This is terrifying. Fortunato has no escape

Okay man Fortunato's tryna leave now I thought he was your friend

So you not only chained him down, but are building a wall too so he can't get back. Didn't you just say he should turn back? He literally can't now??

first EJACULATED HUH????? Also he really just cares about the wine

wow yeah he just chained him up what on earth

restrained with chains or manacles, typically around the ankles. Woah you just straight up chained your friend?

It's cold, dark, the air is awful, Fortunato is barely able to walk, it feels grim

Fortunato is struggling to keep himself up

Narrator is a mason? also, what is the brotherhood?

Is this more like a karma situation? do good and you will be lucky? Is Fortunato a someone? <br /> I wrote that before finding out it was just a character. Maybe this is just saying Fortunato was not justified in doing harm to the narrator.

Narrator yet again telling fortunato to turn back

Without AI being set up properly it could set up any of these institutions up for failure, but if it is then it could have a enterprise-wide impact.

It is already having an increasing affect in Productivity and more specifically in the organization field.

These industries are realizing that there are more positives in adding AI and how AI could positively increase their productivity and numbers.

able to increase productivity.

This shows how AI isn't just a quick fix and something to instantly get you results rather you have to work on it so then it could be more productive in the long run.

It seems to already having a positive affect on the banking community

This shows the massive impact AI is having and how much money is being made because of it and provides facts how it has increased from 2.8 to 4.7%

Estas estratégias podem ser ensinadas e devem ser adaptadas às necessidades e estilos dos alunos, sendo fundamentais para a aprendizagem autônoma. Por sua vez, as estratégias de ensino referem-se às técnicas e métodos que os professores utilizam para transmitir conceitos e habilidades, variando conforme o conteúdo e os objetivos educacionais.

Não obstante esta ideia, sobre a importância de uma e-atividade para a construção do conhecimento, do meu ponto de vista um outro aspeto a realçar, relaciona-se a avaliação, Considero que a avaliação desempenha um papel central numa e-atividade, pois é através dela que se mede o progresso dos estudantes, se ajusta o processo de ensino-aprendizagem e se promove a reflexão sobre o conhecimento adquirido. Em ambientes digitais, tais como nos outros, a avaliação formativa é muito relevante devido às características dos modelos de autonomia e flexibilidade que marcam a educação online. A avaliação é, portanto, uma "ferramenta" essencial para garantir a eficácia das e-atividades e deve ser projetada com base em princípios pedagógicos sólidos. Saudações académicas

A transversalidade evidente deste instrumento de trabalho na concretização dos diferentes estádios do modelo de Gilly Salmon, traduz de uma forma clara a importância que as e-atividades têm na conceção e estruturação de processos de ensino-aprendizagem em ambientes virtuais. António Costa

Há premissas importantes que servem para estruturar o pensamento na fase de conceção das e-atividades. Gostaria de sublinhar a importância de que elementos como a correta adequação dos conteúdos e os consequentes objetivos de aprendizagem estejam logicamente alinhados. A clareza das instruções/orientações deve ser condição fundamental, para assim existir uma progressão lógica nas diferentes etapas/fases da e-atividade, garantindo, desta forma, uma aprendizagem efetiva por parte dos alunos. Também será importante que o professor divulgue os resultados e faça um balanço de uma dada e-atividade, garantindo assim que os alunos tomam consciência da medida de concretização dos objetivos propostos, validando dessa forma eventuais oportunidades de melhoria. António Costa

Num contexto de ensino a distância digital, a planificação de E-atividades proporciona ao formando uma maior noção da sua assimilação de conceitos, conteúdos e consiste num método de avaliação de aprendizagens. São sem dúvida uma forma dinâmica e interativa de promover uma aprendizagem ativa, autónoma e onde se privilegia o pensamento crítico. De acordo com Almenara, Osuna & Cejudo (2014) e transportando-nos para um ambiente virtual, as e-atividades são o elemento que facilita a inter-relação entre o Ensino e a Aprendizagem. Na perspetiva do formador os desafios que se colocam ao desenhar uma e-atividade são vários, nomeadamente, ser objetivo, claro, adequar os conteúdos, conhecer os públicos, definir o tempo, apresentar recursos, selecionar o formato mais adequado, diversificar e avaliar.

Em forma de conclusão as e-atividades permitem uma aprendizagem online ativa, participativa, colaborativa, seja desenvolvida de forma individual ou em grupo e cujo principal objetivo centra-se nas aprendizagens.

Esta tarefa que nos cabe a nós não é fácil, porque temos de ter vários fatores em consideração, tais como, o objetivo e finalidade do curso, a faixa etária, a aplicabilidade prática, etc...

Acho interessante este modelo de desenho de uma e-atividade de acordo com Almenara Osuna & Cejudo mas também gostei da proposta do Maina

o feedback é muito importante, ajuda os alunos a compreenderem melhor seus erros e acertos, proporcionando uma direção clara sobre como melhorar suas habilidades e conhecimentos.

This paragraph should have an indentation.

There is no descriptive caption for this graph, and it should also be labeled as figure 1.

It would be nice for a list of all packages that will be used so we can activate them.

This article angers me far beyond what it should. It is supposed to be a call to action for society to stop treating introverts like they're inferior. As an introvert myself I feel belittled reading this. Like I'm the victim and that it is a negative trait to be an introvert. While it's supposed to be a positive trait according to the article (Oh look, I'm introverted and that makes me a GREAT leader). All it does is just list the author's problems with being an introvert, but all of what she did list is barely traits of being an introvert, it's traits of being a coward with no self-confidence and a victim complex. Being an introvert or an extrovert is neither good nor bad, it's just what it is.

this shows how the way she is labelled doesnt define her. The outside appeance isnt always what is true on the inside

Implies some sort of social conditioning.

The Tirukkuṟaḷ, a Tamil text from the "Global South" that is at least 1500 year old, contains "narratives of 'hard work'". The idea that this is somehow a Global North concept is woefully ignorant.

Couplet 620:

Who strive with undismayed, unfaltering mind, At length shall leave opposing fate behind.

Miles, 1905 uses an arrow symbol with a hash on it to indicate a "connecting link between two Sentences or Paragraphs, etc."

It's certainly an early example of what we would now consider a hyperlink. It actively uses a "pointer" in it's incarnation.

Are there earlier examples of these sorts of idea links in the historical record? Surely there were circles and arrows on a contiguous page, but what about links from one place to separate places (possibly using page numbers?) Indexing methods from 11/12C certainly acted as explicit sorts of pointers.

When was the use of the caret first made for indicating the insertion of material?

Eustace Miles has an example from 1905.

Eustace Miles suggests the use of "special marks on cards" (annotations) in the top left corners, though he doesn't provide specific examples of how they might be used in practice. He does mention "The Abbreviations and Marks need be clear only to the Writer [sic] himself. They save ever so much time."

• "X": As contrasted with—
• "Q": Quotation
• Black triangle in corner: important
• Arrow pointing to corner of card: As compared with
• Angled parallel lines in the bottom right corner of card: End of Paragraph (or Chapter).
• Arrow pointing to the corner of card with hash mark: Connecting Link between two Sentences or Paragraphs, etc.
• Upside down V (or caret): An omission, e.g. to be filled in afterwards
• ?: A doubtful point

In Miles' visual examples of cards, he presents them in portrait (rather than landscape) orientation.

This goes against the broad grain of most standard card index filing systems of the time, but may be more in line with the earlier French use of playing cards orientation.

His portrait orientation also matches with the size ratios seen in his Card-Tray suggestion on p187. https://hypothes.is/a/llEgpIf4Ee-dVfcaIGUryQ

He's repeating (and thus emphasizing) the admonition that a card system is not expensive, particularly in relation to the savings in time and effort.

Miles suggests using a Card-Tray (in 1899) with various compartments and potentially an open top rather than some of the individual trays or card index boxes which may have been more ubiquitous

This shows a slight difference at the time in how an individual would use one of these in writing versus how a business might use them in drawers of 1, 2, 3 or cabinets with many more.

The image he shows seems more reminiscent of a 5x3" library charging tray than of some of the business filing appliances of the day and the decade following.

very similar to the self-made version at https://hypothes.is/a/DHU_-If6Ee-mGieKOjg8ZQ

How does he define "labelled" and "catalogued"?

Presumably he means a version of tagging/categorization and possibly indexing them to be able to easily find them again?

Miles goes against the grain of using "cards of equal size", but does so to emphasize the affordance of using them for "Arrangement and Clearness".

Miles admits that one can use both sides of index cards in a card system, but primarily because he's writing at a time (1899) when, although paper is cheap (which he mentions earlier), some people may have an objection to the system's use due to the expense, which he places at the top of his list of objections. (And he does this in a book in which he emphasizes multiple times the ideas of selection and ordering!)

Miles lists the following objections: - expense - inconvenience - unusual (new, novel)

Notice that he starts not with benefits or affordances, but with the objections.

What would a 2024 list of objections look like? - anachronism - harder than digital methods - lack of easier search - complexity - ... others?

Miles' uses the ubiquity of card systems (even at the writing in 1899, prior to publication) within business as evidence for bolstering their use in writing and composition.

(Recall that he's also writing in the UK.)

Interesting to see a mention of Alphonse Loisette here!

But also nice to see the concept of linking ideas and association (associative memory) pop up here in the context of note making, writing, and creating card systems.

This book was finally published in 1905. The introduction was written in 1899 and the mentioned Feb 1900 publication of How to Remember didn't happen until 1901.

Miles, Eustace Hamilton. How to Remember: Without Memory Systems or with Them. Frederick Warne & Co., 1901.

writing and waiting is useful in many instances, and particularly for clarity of expression.

Using a card system, particularly while travelling, can help to more efficiently use one's time in preventing idleness while travelling and waiting.

where is the balance?

It could be interesting/useful to create a checklist or set of procedures (perhaps a la Oblique Strategies") for editing a major work.

Sections in this TOC could be useful for creating such.

relationship to Adler's levels of reading?

Even in 1905 writers had to wait interminably after submitting their writing...

it's only gotten worse since then...

The process of having a work typewritten forced the affordance of creating time away from the writing of a piece. This allows for both active and diffuse thinking on the piece as well as the ability to re-approach it with fresh eyes days or weeks later.

Even as early as 1905 (or 1899 if we go by the dating of the introduction), typewritten manuscripts were de rigueur for submission to editors and publishers.

Note that he's writing in 1899 (via the introduction), and certainly not later than 1905 (publication date).

One of the major values of fame is that it often allows the dropping of context in communication between people.

Example: Carlyle references in @Miles1905

It bears noting in this book on writing and composition, Miles (nor the indexer if it was done by someone else) never uses Carlyle's first name (Thomas) in any of the eleven instances in which it appears, as he's famous enough in the context (space, time) to need only a single name.

One ought to ask what purpose this Rhyme serves?

• Providing emphasis of the material in the chapter;
• scaffolding for hanging the rest of the material of the book upon, and
• potentially meant to be memorized as a sort of outline of the book and the material.

did I miss the "rhyme" in this section or is he using a more figurative sense (as in "rhyme or reason")?

Ha! Didn't get far enough, it's on page 36, but also works the other way as well.

This chapter is essentially what one ought to glean from skimming the TOC, the Index, and doing a brief inspectional read (Adler, 1972).

Echoes of my own advice to "practice, practice, practice".

Definition of the "first department of composition": <br /> The preparation (mise en place) for writing as opposed to the actual expression of the writing. By this he likely means the actions of Part II (collecting, selecting, arranging) of this book versus Part III.

How is this accomplished exactly? How could one imitate this effect?

How do we break down his material and style to re-create it?

"Brevity is not always the same as Vigour, but the two generally go hand in hand." -Miles

Notice that again he's emphasizing breaking down the problem into steps, and he's using a little analogy to do so, just like he had described previously.

(see: https://hypothes.is/a/NDArGoemEe-9BXcYJSUyMQ)

Attempting to escape the huge list of potential "Chief faults in composition" is a solid reason not to try to cram a paper or essay in a single night/day.

By abstracting and concatenating portions of material, one can more efficiently learn material that would otherwise take more time.

This shows that people don't like slaves so much that they don't want them to have a family and they can do anything to their slaves like they own the slaves which is very cruel.

This just shows the amount of hate for people with a darker skin color which is just completely un human.

Even though slavery ended this quote is explaining that the effects of slavery was racism which was never ending or it would take a very long time to end.

This quote shows how the African slaves were treated especially with their children which were separated away from them and sold to other people to work or one day become another slave and those kids would not know anything about them or their families.

Important to discuss

This last section maybe a good solution to the issue of loot box addiction.

An interesting study to look at

Both problem gambling and financial consequences are a good aspect to look at the issue of online gambling and loot boxes.

Helps strengthens the previous claim of lonely individuals being vulnerable to loot boxes.

Potentially be used to show how loot boxes and addiction to said loot boxes are indiscriminate of genders, nationalities, and age groups.

The connection between loot boxes and indebtedness may be indirect. However, researching further in problem gambling may produce help claims that strength the research question.

Need to find further studies for after the pandemic but this can be a good baseline on how individuals can be affected by the 'predatory monetization schemes' as previously mentioned in the journal.

This overall feeling of indebtness can help strength the claim of the similarity of hopelessness that gambling produces to what loot boxes produce.

Potentially looking for cases of severe loot box addictions can help improve the claim of how these loot boxes mask the true nature of online gambling.

It is good to bring up how much these individuals may spend.

Good to further look into as these 'predatory monetization schemes' could be a point to bring up in how these loot boxes can change the perception of online gambling by posing as a lighter form of online gambling in a way?

The term gambling-like activity can be key in placing loot boxes as an activity closely linked to gambling.

Good point to bring up in the dangers of gambling.

Potentially a good angle to describe the individuals that might be the most vulnerable to loot boxes and online gambling in general.

These studies would be helpful in strengthening the claim on how those how are mentally struggling are the most vulnerable. These studies can also supplement the potentially connection to how loot box purchasing can have adverse affects on mental health. However, this claim will require additional research using multiple sources and studies.

Good definition for what a loot box is. Also helps present the loot box as a form of in-game purchase based on luck.

Strong point that be used as an argument on why loot boxes can hurt individuals with its similarities to gambling. This can also help show how loot boxes promote a form of online gambling.

Hello there, folks.

Thanks once again for joining.

Now that we've got a little bit of an understanding of what problem cloud is solving, let's actually go ahead and define it.

So what we'll talk about is technology on tap, a common phrase that you might have heard about when talking about cloud.

What is it and why would we say that?

Then what we're actually going to do is walk through the NIST definition of cloud.

So there are five key properties that the National Institute of Standards and Technology does use to determine whether or not something is cloud.

So we'll walk through that.

So we've got a good understanding of what cloud is and what cloud is not.

So first things first, technology on tap.

Why would we refer to cloud as technology on tap?

Well, let's have a think about the taps we do know about.

When you want access to water, if you're lucky enough to have access to a nice and easy supply of water, all you really need to do is turn on your tap and get access to as little or as much water as you want.

You can turn that on and off as you require.

Now, we know that that's easy for us.

All we have to worry about is the tap and paying the bill for the amount of water that we consume.

But what we don't really have to worry about is everything that goes in behind the scenes.

So the treatment of the water to bring it up to drinking standards, the actual storage of that treated water, and then the transportation of that through the piping network to actually get to our tap.

All of that is managed for us.

We don't need to really worry about what happens behind the scenes.

All we do is focus on that tap.

We turn it on if we want more.

We turn it off when we are finished.

We only pay for what we consume.

So you might be able to see where I'm going with this.

This is exactly what we are talking about with cloud.

With cloud, however, it's not water that we're getting access to, it is technology.

So if we want access to technology, we use the cloud.

We push some buttons, we click on an interface, we use whatever tool we require, and we get access to those servers, that storage, that database, whatever it might be that we require in the cloud.

Now again, behind the scenes, we don't have to worry about the data centers that host all of this technology, all of these services that we want access to.

We don't worry about the physical infrastructure, the hosting infrastructure, the storage, all the different bits and pieces that actually get that technology to us, we don't need to worry about.

And how does it get to us?

How is it available all across the globe?

Well, we don't need to worry about that connectivity and delivery as well.

All of this behind the scenes when we use cloud is managed for us.

All we have to worry about is turning on or off services as we require.

And this is why you can hear cloud being referred to as technology on tap, because it is very similar to the water utility service.

Utility service is another name you might hear cloud being referred to, because it's like water or electricity.

Cloud are like these utility services where you don't have to worry about all the infrastructure behind the scenes.

You just worry about the thing that you want access to.

And really importantly, you only have to pay for what you use.

You turn it on if you need it, you turn it on if you don't, you create things when you need them, delete them when you don't, and you only pay for those services when you have them, even though they are constantly available at your fingertips.

Now, compare this to the scenario we walked through earlier.

Traditionally, we would have to buy all of the infrastructure, have it sitting there idly, even if we weren't using it, we would still have had to pay for it, set it up, power it and keep it all running.

So this is a high level of what we are talking about with cloud.

Easy access to servers when you need them, turn them off when you don't, don't worry about all that infrastructure behind the scenes.

But that's a high level definition.

So let's now walk through what the NIST use as the key properties to define cloud.

One of the first properties you can use to understand whether something is or is not cloud is understanding whether or not it provides you on demand self service access, where you can easily go ahead and get that technology without even having to talk to humans.

So what do I really mean by that?

Well, let's say you're a cloud administrator, you want to go ahead and access some resources in the cloud.

Now, if you do want access to some services, some data, some storage and application, whatever it might be, while you're probably going to have some sort of admin interface that you can use, whether that's a command line tool or some sort of graphical user interface, you can easily use that to turn on any of the services that you need, web applications, data, storage, compute and much, much more.

And you don't have to go ahead, talk to another human, procure all of the infrastructure that runs behind the scenes.

You use your tool, it is self service, it is on demand, create it when you want it, delete it when you don't.

So that's on demand self service access and one of the key properties of the cloud.

Next, what I want to talk to you about is broad network access.

Now, this is where we're just saying, if something is cloud, it should be easy for you to access through standard capabilities.

So for example, if we are the cloud administrator, it's pretty common when you're working with technology to expect that you would have command line tools, web based tools and so on.

But even when we're not talking about cloud administrators and we're actually talking about the end users, maybe for example, accessing storage, it should be easy for them to do so through standard tools as well, such as a desktop application, a web browser or something similar.

Or maybe you've gone ahead and deployed a reporting solution in the cloud, like we spoke of in the previous lesson.

Well, you would commonly expect for that sort of solution that maybe there's also a mobile application to go and access all of that reporting data.

The key point here is that if you are using cloud, it is expected that all of the common standard sorts of accessibility options are available to you, public access, private access, desktop applications, mobile applications and so on.

So if that's what cloud is and how we access it, where actually is it?

That's a really important part of the definition of cloud.

And that's where we're referring to resource pooling, this idea that you don't really know exactly where the cloud is that you are going to access.

So let's say for example, you've got your Aussie Mart company.

If they want to deploy their solution to be available across the globe, well, it should be pretty easy for them to actually go ahead and do that.

Now, we don't know necessarily where that is.

We can get access to it.

We might say, I want my solution available in Australia East for example, or Europe or India or maybe central US for example.

All of these refer to general locations where we want to deploy our services.

When you use cloud, you are not going to go ahead and say, I want one server and I want it deployed to the data center at 123 data center street.

Okay, you don't know the physical address exactly or at least you shouldn't really have to.

All you need to know about is generally where you are going to go and deploy that.

Now, you will also see that for most cloud providers, you've got that global access in terms of all the different locations you can deploy to.

And really importantly, in terms of all of these pooled resources, understand that it's not just for you to use.

There will be other customers all across the globe who are using that as well.

So when you're using cloud, there are lots of resources.

They might be in lots of different physical locations and lots of different physical infrastructure and in use by lots of different customers.

And you don't really need to worry about that or know too much about it.

Another really important property of the cloud is something referred to as rapid elasticity.

Now elasticity is the idea that you can easily get access to more or less resources.

And when you work with cloud, you're actually going to commonly hear this being referred to as scaling out and in rather than just scaling up and down.

So what do I mean by that?

Well, let's say we've got our users that need to access our Aussie Mart store.

We might decide to use cloud to host our Aussie Mart web application.

And perhaps that's hosted on a server and a database.

Now, when that application gets really busy, for example, if we have lots of different users going to access it at the same time, we might want to scale out to meet demand.

That is to say, rather than having one server that hosts our web application, we might actually have three.

And if that demand for our application decreases, we might actually go ahead and decrease the underlying resources that power it as well.

What we are talking about here is scaling in and out by adding or decreasing the number of resources that host our application.

This is different from the traditional approach to scalability, where what we would normally do is just add CPU or add memory, for example.

We would increase the size of one individual resource that was hosting our solution.

So that's just elasticity at a high level and it's a really key property of cloud.

Now, we'll just say here that if you are worried about how that actually works behind the scenes in terms of how you host that application across duplicate resources, how you provide connectivity to that, that's all outside the scope of this beginners course, but it's definitely covered in other content as well.

So when you're using cloud, you get easy access to scale in and out and you should never feel like there are not enough resources to meet your demand.

To you, it should just feel like if you want a hundred servers, for example, then you can easily get a hundred servers.

All right, now the last property of cloud that I want to talk to you about is that of measuring service.

When we're talking about measuring service, what we're talking about is the idea that if you are using cloud to host your solutions, it should be really easy for you to go and say, I know what this is costing, I know where my resources are, how they are performing and whether there are any issues and I can control the types of resources and the configuration that I use that I'm going to deploy.

So for example, it should be easy for you to say, how much is it going to cost me for five gigabytes of storage?

What does my bill look like currently and what am I forecasted to be using over the remainder of the month?

Or maybe you want to say that certain services should not be allowed to be deployed across all regions.

Yes, cloud can be accessed across the globe, but maybe your organization only works in one part of a specific country and that's the only location you should be able to use.

These are the standard notions of measuring and controlling service and it's really common to all of the cloud providers.

All right, everybody.

So now you've got an understanding of what cloud is and how you can define it.

If you'd like to see more about this definition from the NIST, then be sure to check out the link that I've included for this lesson.

So thanks for joining me, folks.

I'll see you in the next lesson.

I would be interested to see if traditional focused meditation would have similar results.

Let's review these other studies as well.

Interesting.

How is this measured? Edit: Addressed further down.

What is the size and composition of the group? Edit: Addressed further down.

Is this quantified?

Very interesting. I thought the whole purpose of meditation WAS the struggle to control the thoughts. I thought that is where the benefits came from.

Certainly would make it more approachable.

This would imply improved equanimity, but perhaps not long term focus improvement.

This particular study seems to show that the change in focus efficiency was actually better in the control group than the experiment group.

Hey there everybody, thanks for joining.

It's great to have you with me in this lesson where we're going to talk about why cloud matters.

Now to help answer that question, what I want to do firstly is talk to you about the traditional IT infrastructure.

How did we used to do things?

What sort of challenges and issues did we face?

And therefore we'll get a better understanding of what cloud is actually doing to help.

We can look at how things used to be and how things are now.

So what we're going to do throughout this lesson is walk through a little bit of a scenario with a fictitious company called Ozzymart.

So let's go ahead now, jump in and have a chat about the issues that they're currently facing.

Ozzymart is a fictitious company that works across the globe selling a range of different Australia related paraphernalia.

Maybe stuffed toys for kangaroos, koalas and that sort of thing.

Now they've currently got several different applications that they use that they provide access to for their users.

And currently the Ozzymart team do not use the cloud.

So when we have a look at the infrastructure hosting these applications, we'll learn that Ozzymart have a couple of servers, one server for each of the applications that they've got configured.

Now the Ozzymart IT team have had to have gone and set up these servers with windows, the applications and all the different data that they need for these applications to work.

And what it's also important to understand about the Ozzymart infrastructure is all of this is currently hosted on their on-premises customer managed infrastructure.

So yes, the Ozzymart team could have gone out and maybe used a data center provider.

But the key point here is that the Ozzymart IT team have had to set up servers, operating systems, applications and a range of other infrastructure to support all of this storage, networking, power, cooling.

Okay, these are the sorts of things that we have to manage traditionally before we were able to use cloud.

Now to help understand what sort of challenges that might introduce, let's walk through a scenario.

We're going to say that the Ozzymart CEO has gone and identified the need for reporting to be performed across these two applications.

And the CEO wants those reports to be up and ready by the end of this month.

Let's say that's only a week away.

So the CEO has instructed the finance manager and the finance manager has said, "Hey, awesome.

You know what?

I've found this great app out there on the internet called Reports For You.

We can buy it, download it and install it.

I'm going to go tell the IT team to get this up and running straight away."

So this might sound a little bit familiar to some of you who have worked in traditional IT where sometimes demands can come from the top of the organization and they filter down with really tight timelines.

So let's say for example, the finance manager is going to go along, talk to the IT team and say, "We need this Reports For You application set up by the end of month."

Now the IT team might be a little bit scared because, hey, when we look at the infrastructure we've got, it's supporting those two servers and applications okay, but maybe we don't have much more space.

Maybe we don't have enough storage.

Maybe we are using something like virtualization.

So we might not need to buy a brand new physical server and we can run up a virtual Windows server for the Reports For You application.

But there might just not be enough resources in general.

CPU, memory, storage, whatever it might be to be able to meet the demands of this Reports For You application.

But you've got a timeline.

So you go ahead, you get that server up and running.

You install the applications, the operating system data, all there as quickly as you can to meet these timelines that you've been given by the finance manager.

Now maybe it's not the best server that you've ever built.

It might be a little bit rushed and a little bit squished, but you've managed to get that server up and running with the Reports For You application and you've been able to meet those timelines and provide access to your users.

Now let's say that you've given access to your users for this Reports For You application.

Now let's say when they start that monthly reporting job, the Reports For You application needs to talk to the data across your other two applications, the Aussie Mart Store and the Aussie Mart Comply application.

And it's going to use that data to perform the reporting that the CEO has requested.

So you kick off this report job on a Friday.

You hope that it's going to be complete on a Saturday, but maybe it's not.

You check again on a Sunday and things are starting to get a little bit scary.

And uh-oh, Monday rolls around, the Reports For You report is still running.

It has not yet complete.

And that might not be so great because you don't have a lot of resources on-premises.

And now all of your applications are starting to perform really poorly.

So that Reports For You application is still running.

It's still trying to read data from those other two applications.

And maybe they're getting really, really slow and let's hope not, but maybe the applications even go off entirely.

Now those users are going to become pretty angry.

You're going to get a lot of calls to the help desk saying that things are offline.

And you're probably going to have the finance manager and every other manager reaching out to you saying, this needs to be fixed now.

So let's say you managed to push through, perhaps through the rest of Monday, and that report finally finishes.

You clearly need more resources to be able to run this report much more quickly at the end of each month so that you don't have angry users.

So what are you going to do to fix this for the next month when you need to run the report again?

Well, you might have a think about ordering some new software and hardware because you clearly don't have enough hardware on-premises right now.

You're going to have to wait some time for all of that to be delivered.

And then you're going to have to physically and store it, set it up, get it running, and make sure that you've got everything you need for reports for you to be running with more CPU and resources next time.

There's a lot of different work that you need to do.

This is one of the traditional IT challenges that we might face when the business has demands and expectations for things to happen quickly.

And it's not really necessarily the CEO or the finance manager's fault.

They are focused on what the business needs.

And when you work in the technology teams, you need to do what you can to support them so that the business can succeed.

So how might we do that a little bit differently with cloud?

Well, with cloud, we could sign up for a cloud provider, we could turn on and off servers as needed, and we could scale up and scale down, scale in and scale out resources, all to meet those demands on a monthly basis.

So that could be a lot less work to do and it could certainly provide you the ability to respond much more quickly to the demands that come from the business.

And rather than having to go out and buy all of this new infrastructure that you are only going to use once a month, well, as we're going to learn throughout this course, one of the many benefits of cloud is that you can turn things on and off really quickly and only pay for what you need.

So what might this look like with cloud?

Well, with cloud, what we might do is no longer have that on-premises rushed server that we were using for reports for you.

Instead of that, we can go out to a public cloud provider like AWS, GCP or hopefully Azure, and you can set up those servers once again using a range of different features, products that are all available through the various public cloud providers.

Now, yes, in this scenario, we are still talking about setting up a server.

So that is going to take you some time to configure Windows, set up the application, all of the data and configuration that you require, but at least you don't need to worry about the actual physical infrastructure that is supporting that server.

You don't have to go out, talk to your procurement team, talk to a different providers, wait for different physical infrastructure to be delivered and licensing and software and other assets.

With cloud, as we will learn, you can really quickly get online and up and running.

And also, if we had that need to ensure that the reports for you application was running with lots of different resources at the end of the month, it's much easier when we use cloud to just go and turn some servers on and then maybe turn them off at the end of the month when they are no longer acquired.

This is the sort of thing that we are talking about with cloud.

We're only really just touching on the service about what cloud can do and what cloud actually is.

But my hope is that through this lesson, you can understand how cloud changes things.

Cloud allows us to work with technology in a much different way than we traditionally would work with our on-premises infrastructure.

Another example that shows how cloud is different is that rather than using the reports for you application, what we might in fact actually choose to do is go to a public cloud provider and go to someone that actually has a equivalent reports for you solution that's entirely built in the cloud ready to go.

In this way, not only do we no longer have to manage the underlying physical infrastructure, we don't actually have to manage the application software installation, configuration, and all of that service setup.

With something like a reporting software that's built in the cloud, we would just provide access to our users and only have to pay on a per user basis.

So if you've used something like zoom for meetings or Dropbox for data sharing, that's the sort of solution we're talking about.

So if we consider this scenario for Aussie Mart, we have a think about the benefits that they might access when they use the cloud.

Well, we can much more quickly get access to resources to respond to demand.

If we need to have a lot of different compute capacity working at the end of the month with cloud, like you'll learn, we can easily get access to that.

If we wanted to add lots of users, we could do that much more simply as well.

And something that the finance manager might really be happy about in this scenario is that we aren't going to go back and suggest to them that we need to buy a whole heap of new physical infrastructure right now.

When we think about traditionally how Aussie Mart would have worked with this scenario, they would have to go and buy some new physical servers, resources, storage, networking, whatever that might be, to meet the needs of this reports for you application.

And really, they're probably going to have to strike a balance between having enough infrastructure to ensure that the reports for you application completes its job quickly and not buying too much infrastructure that's just going to be sitting there unused whilst the reports for you application is not working.

And really importantly, when we go to cloud, we see this difference as not having to buy lots of physical infrastructure upfront as being referred to as capital expenditure versus operational expenditure.

Really, what we're just saying here is rather than spending a whole big lump sum all at once to get what you need, you can just pay on a monthly basis for what you need when you need it.

And finally, one of the other benefits that you'll also see is that we're getting a reduction in the amount of different tasks that we have to complete in terms of IT administration, set up of operating systems, management of physical infrastructure, what the procurement team has to manage, and so on.

Again, right now we're just talking really high level about a fictitious scenario for Aussie Mart to help you to understand the types of things and the types of benefits that we can get access to for cloud.

So hopefully if you're embarking on a cloud journey, you're gonna have a happy finance manager, CEO, and other team members that you're working with as well.

Okay, everybody, so that's a wrap to this lesson on why cloud matters.

As I've said, we're really only just scratching the surface.

This is just to introduce you to a scenario that can help you to understand the types of benefits we get access to with cloud.

As we move throughout this course, we'll progressively dive deeper in terms of what cloud is, how you define it, the features you get access to, and other common concepts and terms.

So thanks for joining me, I'll see you there.

Marrim feels that hookah is a big part of her life because it helped her feel liberated even though she was looked as shameful because she is a women but that did not stop her she would make her own hookah when she was younger to smoke some hookah she's not wrong kids like to break the rules

due to hookah being Tabaco that you inhale in to your lungs so it's still a health problem because you get smoke in your lungs.

The hookah lounge is more then a place to smoke it a place where people to together to celebrate special events like birthdays or to relief dome stress or hang with friends.

hookah is a sacred traditions for Muslim people they don't know if they will every go home some day so to keep their tradition hookah is important for them.

The water that has only recently brought about death to an unfortunate sailor and has seemingly threatened “Gentile[s]” and “Jew[s]” and even us, the readers, now becomes the force an absence of which leads to death. What if the “death by water” that Madame Sosotris warned about was not the drowning but the death brought by its lack? This absence—spiritual and physical—defines the drought that pervades society.

In essence, that warning has already become true. In the search of meaning, the earthly desires have drowned humanity. What comes after it is stillness: a period of profound spiritual drought. This lack of spiritually induces apocalypse: a cycle of life seemingly becomes broken. The silence in the mountains does not give way to voice, and stillness, described in The Death of Water, that follows the storm does not imply recovery; instead, it leads to further destruction. There is no resurgence after the storm, only desolation.

This desolation is no less overwhelming than the indulgence that preceded it. The absence of water—a metaphor for spiritual sustenance—is inescapable. The mountains, once symbols of “solitude,” “silence” and reflection are now dry and barren. The use of “even” in these lines underscores the notion of the totality of this spiritual drought. There is no refuge, no shelter, not “even” in the mountains.

Eliot further juxtaposes biblical light, associated with Christ as “the sun shineth in his strength,” as described in Revelations, with thunder, transforming it into a symbol of apocalypse – the thunder itself represents a loud rumbling or crashing noise after a lightning flash. This choice of title and imagery seems to suggest that divine intervention may have already occurred—unrecognized and unheeded, leaving only a loud noice as its product. What if Jesus is already here “walking beside” us? Left unrecognized, however, he does not intervene. This notion is underscored by the repetition of the question regarding the personality of this third creature: “Who is the third who walks always beside you?” In the second reiteration of the question, however, “beside” changes to “on the other side.” This divine creature, most likely Christ, is present, yet now isolated, by the walls of mountains we ourselves have built.

The tragedy of this drought, thus, seems to lie not in the absence of divine intervention, but in humanity’s inability to recognize it. In this contemporary world, it is not the storm that destroys; it is the stillness after, where the absence of recognition leads to a deeper decay. The apocalypse has already begun (or potentially has almost reached its culmination), not in fire or flood, but in silence and spiritual blindness.

Welcome back and in this lesson I want to talk through another type of storage.

This time instant store volumes.

It's essential for all of the AWS exams and real-world usage that you understand the pros and cons for this type of storage.

It can save money, improve performance or it can cause significant headaches so you have to appreciate all of the different factors.

So let's just jump in and get started because we've got a lot to cover.

Instant store volumes provide block storage devices so raw volumes which can be attached to an instance presented to the operating system on that instance and used as the basis for a file system which can then in turn be used by applications.

So far they're just like EBS only local instead of being presented over the network.

These volumes are physically connected to one EC2 host and that's really important.

Each EC2 host has its own instant store volumes and they're isolated to that one particular host.

Instances which are on that host can access those volumes and because they're locally attached they offer the highest storage performance available within AWS much higher than EBS can provide and more on why this is relevant very soon.

They're also included in the price of any instances which they come with.

Different instance types come with different selections of instant store volumes and for any instances which include instant store volumes they're included in the price of that instance so it comes down to use it or lose it.

One really important thing about instant store volumes is that you have to attach them at launch time and unlike EBS you can't attach them afterwards.

I've seen this question come up a few times in various AWS exams about adding new instant store volumes after instance launch and it's important that you remember that you can't do this it's launch time only.

Depending on the instance type you're going to be allocated a certain number of instant store volumes you can choose to use them or not but if you don't you can't adjust this later.

This is how instant store architecture looks.

Each instance can have a collection of volumes which are backed by physical devices on the EC2 host which that instance is running on.

So in this case host A has three physical devices and these are presented as three instant store volumes and host B has the same three physical devices.

Now in reality EC2 hosts will have many more but this is a simplified diagram.

Now on host A instance 1 and 2 are running instance 1 is using one volume and instance 2 is using the other two volumes and the volumes are named ephemeral 0, 1 and 2.

Roughly the same architecture is present on host B but instance 3 is the only instance running on that host and it's using ephemeral 1 and ephemeral 2 volumes.

Now these are ephemeral volumes they're temporary storage as a solutions architect or a developer or an engineer you need to think of them as such.

If instance 1 stored some data on ephemeral volume 0 on EC2 host A let's say a cat picture and then for some reason the instance migrated from host A through to host B then it would still have access to an ephemeral 0 volume but it would be a new physical volume a blank block device.

So this is important if an instance moves between hosts then any data that was present on the instant store volumes is lost and instances can move between hosts for many reasons.

If they're stopped and started this causes a migration between hosts or another example is if host A was undergoing maintenance then instances would be migrated to a different host.

When instances move between hosts they're given new blank ephemeral volumes data on the old volumes is lost they're wiped before being reassigned but the data is gone and even if you do something like change an instance type this will cause an instance to move between hosts and that instance will no longer have access to the same instant store volumes.

This is another risk to keep in mind you should view all instant store volumes as ephemeral.

The other danger to keep in mind is hardware failure if a physical volume fails say the ephemeral 1 volume on EC2 host A then instance 2 would lose whatever data was on that volume.

These are ephemeral volumes treat them as such their temporary data they should not be used for anything where persistence is required.

Now the size of instant store volumes and the number of volumes available to an instance vary depending on the type of instance and the size of instance.

Some instance types don't support instant store volumes different instance types have different types of instance store volumes and as you increase in size you're generally allocated larger numbers of these volumes so that's something that you need to keep in mind.

One of the primary benefits of instance store volumes is performance you can achieve much higher levels of throughput and more IOPS by using instance store volumes versus EBS.

I won't consume your time by going through every example but some of the higher-end figures that you need to consider are things like if you use a D3 instance which is storage optimized then you can achieve 4.6 GB per second of throughput and this instance type provides large amounts of storage using traditional hard disks so it's really good value for large amounts of storage.

It provides much high levels of throughput than the maximums available when using HDD based EBS volumes.

The I3 series which is another storage optimized family of instances these provide NVMe SSDs and this provides up to 16 GB per second of throughput and this is significantly higher than even the most high performance EBS volumes can provide and the difference in IOPS is even more pronounced versus EBS with certain I3 instances able to provide 2 million read IOPS and 1.6 million write IOPS when optimally configured.

In general instance store volumes perform to a much higher level versus the equivalent storage in EBS.

I'll be doing a comparison of EBS versus instance store elsewhere in this section which will help you in situations where you need to assess suitability but these are some examples of the raw figures.

Now before we finish this lesson just a number of exam power-ups.

Instance store volumes are local to an EC2 host so if an instance does move between hosts you lose access to the data on that volume you can only add instance store volumes to an instance at launch time if you don't add them you cannot come back later and add additional instance store volumes and any data on instance store volumes is lost if that instance moves between hosts if it gets resized or if you have either host failure or specific volume hardware failure.

Now in exchange for all these restrictions of course instance store volumes provide high performance so it's the highest data performance that you can achieve within AWS you just need to be willing to accept all of the shortcomings around the risk of data loss its temporary nature and the fact that it can't survive through restarts or moves or resizes.

It's essentially a performance trade-off you're getting much faster storage as long as you can tolerate all of the restrictions.

Now with instance store volumes you pay for it anyway it's included in the price of an instance so generally when you're provisioning an instance which does come with instance store volumes there is no advantage to not utilizing them you can decide not to use them inside the OS but you can't physically add them to the instance at a later date.

Just to reiterate and I'm going to keep repeating this throughout this section of the course instance store volumes are temporary you cannot use them for any data that you rely on or data which is not replaceable so keep that in mind it does give you amazing performance but it is not for the persistent storage of data but at this point that's all of the theory that I wanted to cover so that's the architecture and some of the performance trade-offs and benefits that you get with instance store volumes go ahead and complete this video and when you're ready join me in the next which will be an architectural comparison of EBS and instance store which will help you in exam situations to pick between the two.

Welcome back and in this lesson I want to talk about the Hard Disk Drive or HDD-based volume types provided by EBS.

HDD-based means they have moving bits, platters which spin little robot arms known as heads which move across those spinning platters.

Moving parts means slower which is why you'd only want to use these volume types in very specific situations.

Now let's jump straight in and look at the types of situations where you would want to use HDD-based storage.

Now there are two types of HDD-based storage within EBS.

Well that's not true, there are actually three but one of them is legacy.

So I'll be covering the two ones which are in general usage.

And those are ST1 which is throughput optimized HDD and SC1 which is cold HDD.

So think about ST1 as the fast hard drive not very agile but pretty fast and think about SC1 as cold.

ST1 is cheap, it's less expensive than the SSD volumes which makes it ideal for any larger volumes of data.

SC1 is even cheaper but it comes with some significant trade-offs.

Now ST1 is designed for data which is sequentially accessed because it's HDD-based it's not great at random access.

It's more designed for data which needs to be written or read in a fairly sequential way.

Applications where throughput and economy is more important than IOPS or extreme levels of performance.

ST1 volumes range from 125 GB to 16 TB in size and you have a maximum of 500 IOPS.

But and this is important IO on HDD-based volumes is measured as 1 MB blocks.

So 500 IOPS means 500 MB per second.

Now their maximums HDD-based storage works in a similar way to how GP2 volumes work with a credit bucket.

Only with HDD-based volumes it's done around MB per second rather than IOPS.

So with ST1 you have a baseline performance of 40 MB per second for every 1 TB of volume size.

And you can burst to a maximum of 250 MB per second for every TB of volume size.

Obviously up to the maximum of 500 IOPS and 500 MB per second.

ST1 is designed for when cost is a concern but you need frequent access storage for throughput intensive sequential workloads.

So things like big data, data warehouses and log processing.

Now ST1 on the other hand is designed for infrequent workloads.

It's geared towards maximum economy when you just want to store lots of data and don't care about performance.

So it offers a maximum of 250 IOPS.

Again this is with a 1 MB IO size.

So this means a maximum of 250 MB per second of throughput.

And just like with ST1 this is based on the same credit pool architecture.

So it has a baseline of 12 MB per TB of volume size and a burst of 80 MB per second per TB of volume size.

So you can see that this offers significantly less performance than ST1 but it's also significantly cheaper.

And just like with ST1 volumes can range from 125 GB to 16 TB in size.

This storage type is the lowest cost EBS storage available.

It's designed for less frequently accessed workloads.

So if you have colder data, archives or anything which requires less than a few loads or scans per day then this is the type of storage volume to pick.

And that's it for HDD based storage.

Both of these are lower cost and lower performance versus SSD.

Designed for when you need economy of data storage.

Picking between them is simple.

If you can tolerate the trade-offs of ST1 then use that.

It's super cheap and for anything which isn't day to day accessed it's perfect.

Otherwise choose ST1.

And if you have a requirement for anything IOPS based then avoid both of these and look at SSD based storage.

With that being said though that's everything that I wanted to cover in this lesson.

Thanks for watching.

Go ahead and complete the video and when you're ready I'll look forward to you joining me in the next.

Welcome back and in this lesson I want to continue my EBS series and talk about provisioned IOPS SSD.

So that means IO1 and IO2.

Let's jump in and get started straight away because we do have a lot to cover.

Strictly speaking there are now three types of provisioned IOPS SSD.

Two which are in general release IO1 and its successor IO2 and one which is in preview which is IO2 Block Express.

Now they all offer slightly different performance characteristics and different prices but the common factors is that IOPS are configurable independent of the size of the volume and they're designed for super high performance situations where low latency and consistency of that low latency are both important characteristics.

With IO1 and IO2 you can achieve a maximum of 64,000 IOPS per volume and that's four times the maximum for GP2 and GP3 and with IO1 and IO2 you can achieve a 1000 MB per second of throughput.

This is the same as GP3 and significantly more than GP2.

Now IO2 Block Express takes this to another level.

With Block Express you can achieve 256,000 IOPS per volume and 4000 MB per second of throughput per volume.

In terms of the volume sizes that you can use with provisioned IOPS SSDs with IO1 and IO2 it ranges from 4 GB to 16 TB and with IO2 Block Express you can use larger up to 64 TB volumes.

Now I mentioned that with these volumes you can allocate IOPS performance values independently of the size of the volume.

Now this is useful for when you need extreme performance for smaller volumes or when you just need extreme performance in general but there is a maximum of the size to performance ratio.

For IO1 it's 50 IOPS per GB of size so this is more than the 3 IOPS per GB for GP2.

For IO2 this increases to 500 IOPS per GB of volume size and for Block Express this is 1000 IOPS per GB of volume size.

Now these are all maximums and with these types of volumes you pay for both the size and the provisioned IOPS that you need.

Now because with these volume types you're dealing with extreme levels of performance there is also another restriction that you need to be aware of and that's the per instance performance.

There is a maximum performance which can be achieved between the EBS service and a single EC2 instance.

Now this is influenced by a few things.

The type of volumes so different volumes have a different maximum per instance performance level, the type of the instance and then finally the size of the instance.

You'll find that only the most modern and largest instances support the highest levels of performance and these per instance maximums will also be more than one volume can provide on its own and so you're going to need multiple volumes to saturate this per instance performance level.

With IO1 volumes you can achieve a maximum of 260,000 IOPS per instance and a throughput of 7,500 MB per second.

It means you'll need just over four volumes of performance operating at maximum to achieve this per instance limit.

Oddly enough IO2 is slightly less at 160,000 IOPS for an entire instance and 4,750 MB per second and that's because AWS have split these new generation volume types.

They've added block express which can achieve 260,000 IOPS and 7,500 MB per second for an instance maximum.

So it's important that you understand that these are per instance maximums so you need multiple volumes all operating together and think of this as a performance cap for an individual EC2 instance.

Now these are the maximums for the volume types but you also need to take into consideration any maximums for the type and size of the instance so all of these things need to align in order to achieve maximum performance.

Now keep these figures locked in your mind it's not so much about the exact numbers but having a good idea about the levels of performance that you can achieve with GP2 or GP3 and then IO1, IO2 and IO2 block express will really help you in real-world situations and in the exam.

Instance store volumes which we're going to be covering elsewhere in this section can achieve even higher performance levels but this comes with a serious limitation in that it's not persistent but more on that soon.

Now as a comparison the per instance maximums for GP2 and GP3 is 260,000 IOPS and 7,000 MB per second per instance.

Again don't focus too much on the exact numbers but you need to have a feel for the ranges that these different types of storage volumes occupy versus each other and versus instance store.

Now you'll be using provisioned IOPS SSD for anything which needs really low latency or sub millisecond latency, consistent latency and higher levels of performance.

One common use case is when you have smaller volumes but need super high performance and that's only achievable with IO1, IO2 and IO2 block express.

Now that's everything that I wanted to cover in this lesson.

Again if you're doing the sysops or developer streams there's going to be a demo lesson where you'll experience the storage performance levels.

For the architecture stream this theory is enough.

At this point though thanks for watching that's everything I wanted to cover go ahead and complete the video and when you're ready I look forward to you joining me in the next.

Ventura Highway, track 14 on the album Here & Now by America (1972-11-04)

It’s unsure whether a connection between this lyric and the famous Prince song (which was released 12 years after “Ventura Highway”) exists, but at least two journalists from The San Diego Union and the Post-Tribune wrote that Prince got the phrase “Purple Rain” from here.

Asked to explain the phrase “purple rain” in “Ventura Highway,” Gerry Beckley responded: “You got me.”

Welcome back and in this lesson I want to talk about two volume types available within AWS GP2 and GP3.

Now GP2 is the default general purpose SSD based storage provided by EBS.

GP3 is a newer storage type which I want to include because I expect it to feature on all of the exams very soon.

Now let's just jump in and get started.

General Purpose SSD storage provided by EBS was a game changer when it was first introduced.

It's high performance storage for a fairly low price.

Now GP2 was the first iteration and it's what I'm going to be covering first because it has a simple but initially difficult to understand architecture.

So I want to get this out of the way first because it will help you understand the different storage types.

When you first create a GP2 volume it can be as small as 1 GB or as large as 16 TB.

And when you create it the volume is created with an I/O credit allocation.

Think of this like a bucket.

So an I/O is one input output operation.

An I/O credit is a 16 kb chunk of data.

So an I/O is one chunk of 16 kilobytes in one second.

If you're transferring a 160 kb file that represents 10 I/O blocks of data.

So 10 blocks of 16 kb.

And if you do that all in one second that's 10 credits in one second.

So 10 I/Ops.

When you aren't using the volume much you aren't using many I/Ops and you aren't using many credits.

During periods of high disc load you're going to be pushing a volume hard and because of that it's consuming more credits.

For example during system boots or backups or heavy database work.

Now if you have no credits in this I/O bucket you can't perform any I/O on the disc.

The I/O bucket has a capacity of 5.4 million I/O credits.

And it fills at the baseline performance rate of the volume.

So what does this mean?

Well every volume has a baseline performance based on its size with a minimum.

So streaming into the bucket at all times is a 100 I/O credits per second refill rate.

This means as an absolute minimum regardless of anything else you can consume 100 I/O credits per second which is 100 I/Ops.

Now the actual baseline rate which you get with GP2 is based on the volume size.

You get 3 I/O credits per second per GB of volume size.

This means that a 100 GB volume gets 300 I/O credits per second refilling the bucket.

Anything below 33.33 recurring GB gets this 100 I/O minimum.

Anything above 33.33 recurring gets 3 times the size of the volume as a baseline performance rate.

Now you aren't limited to only consuming at this baseline rate.

By default GP2 can burst up to 3000 I/Ops so you can do up to 3000 input output operations of 16 kb in one second.

And that's referred to as your burst rate.

It means that if you have heavy workloads which aren't constant you aren't limited by your baseline performance rate of 3 times the GB size of the volume.

So you can have a small volume which has periodic heavy workloads and that's OK.

What's even better is that the credit bucket it starts off full so 5.4 million I/O credits.

And this means that you could run it at 3000 I/Ops so 3000 I/O per second for a full 30 minutes.

And that assumes that your bucket isn't filling up with new credits which it always is.

So in reality you can run at full burst for much longer.

And this is great if your volumes are used initially for any really heavy workloads because this initial allocation is a great buffer.

The key takeaway at this point is if you're consuming more I/O credits than the rate at which your bucket is refilling then you're depleting the bucket.

So if you burst up to 3000 I/Ops and your baseline performance is lower then over time you're decreasing your credit bucket.

If you're consuming less than your baseline performance then your bucket is replenishing.

And one of the key factors of this type of storage is the requirement that you manage all of the credit buckets of all of your volumes.

So you need to ensure that they're staying replenished and not depleting down to zero.

Now because every volume is credited with 3 I/O credits per second for every GB in size, volumes which are up to 1 TB in size they'll use this I/O credit architecture.

But for volumes larger than 1 TB they will have a baseline equal to or exceeding the burst rate of 3000.

And so they will always achieve their baseline performance as standard.

They don't use this credit system.

The maximum I/O per second for GP2 is currently 16000.

So any volumes above 5.33 recurring TB in size achieves this maximum rate constantly.

GP2 is a really flexible type of storage which is good for general usage.

At the time of creating this lesson it's the default but I expect that to change over time to GP3 which I'm going to be talking about next.

GP2 is great for boot volumes, for low latency interactive applications or for dev and test environments.

Anything where you don't have a reason to pick something else.

It can be used for boot volumes and as I've mentioned previously it is currently the default.

Again over time I expect GP3 to replace this as it's actually cheaper in most cases but more on this in a second.

You can also use the elastic volume feature to change the storage type between GP2 and all of the others.

And I'll be showing you how that works in an upcoming lesson if you're doing the CIS Ops or developer associate courses.

If you're doing the architecture stream then this architecture theory is enough.

At this point I want to move on and explain exactly how GP3 is different.

GP3 is also SSD based but it removes the credit bucket architecture of GP2 for something much simpler.

Every GP3 volume regardless of size starts with a standard 3000 IOPS so 3000 16 kB operations per second and it can transfer 125 MB per second.

That standard regardless of volume size and just like GP2 volumes can range from 1 GB through to 16 TB.

Now the base price for GP3 at the time of creating this lesson is 20% cheaper than GP2.

So if you only intend to use up to 3000 IOPS then it's a no brainer.

You should pick GP3 rather than GP2.

If you need more performance then you can pay for up to 16000 IOPS and up to 1000 MB per second of throughput.

And even with those extras generally it works out to be more economical than GP2.

GP3 offers a higher max throughput as well so you can get up to 1000 MB per second versus the 250 MB per second maximum of GP2.

So GP3 is just simpler to understand for most people versus GP2 and I think over time it's going to be the default.

For now though at the time of creating this lesson GP2 is still the default.

In summary GP3 is like GP2 and IO1 which I'll cover soon had a baby.

You get some of the benefits of both in a new type of general purpose SSD storage.

Now the usage scenarios for GP3 are also much the same as GP2.

So virtual desktops, medium sized databases, low latency applications, dev and test environments and boot volumes.

You can safely swap GP2 to GP3 at any point but just be aware that for anything above 3000 IOPS the performance doesn't get added automatically like with GP2 which scales on size.

With GP3 you would need to add these extra IOPS which come at an extra cost and that's the same with any additional throughput.

Beyond the 125 MB per second standard it's an additional extra but still even including those extras for most things this storage type is more economical than GP2.

At this point that's everything that I wanted to cover about the general purpose SSD volume types in this lesson.

Go ahead, complete the lesson and then when you're ready, I'll look forward to you joining me in the next.

Welcome back and in this lesson I want to quickly step through the basics of the Elastic Block Store service known as EBS.

You'll be using EBS directly or indirectly, constantly as you make use of the wider AWS platform and as such you need to understand what it does, how it does it and the product's limitations.

So let's jump in and get started straight away as we have a lot to cover.

EBS is a service which provides block storage.

Now you should know what that is by now.

It's storage which can be addressed using block IDs.

So EBS takes raw physical disks and it presents an allocation of those physical disks and this is known as a volume and these volumes can be written to or read from using a block number on that volume.

Now volumes can be unencrypted or you can choose to encrypt the volume using KMS and I'll be covering that in a separate lesson.

Now you see two instances when you attach a volume to them they see a block device, a raw storage and they can use this to create a file system on top of it such as EXT3, EXT4 or XFS and many more in the case of Linux or alternatively NTFS in the case of Windows.

The important thing to grasp is that EBS volumes appear just like any other storage device to an EC2 instance.

Now storage is provisioned in one availability zone.

I can't stress enough the importance of this.

EBS in one availability zone is different than EBS in another availability zone and different from EBS in another AZ in another region.

EBS is an availability zone service.

It's separate and isolated within that availability zone.

It's also resilient within that availability zone so if a physical storage device fails there's some built-in resiliency but if you do have a major AZ failure then the volumes created within that availability zone will likely fail as will instances also in that availability zone.

Now with EBS you create a volume and you generally attach it to one EC2 instance over a storage network.

With some storage types you can use a feature called Multi-Attach which lets you attach it to multiple EC2 instances at the same time and this is used for clusters but if you do this the cluster application has to manage it so you don't overwrite data and cause data corruption by multiple writes at the same time.

You should by default think of EBS volumes as things which are attached to one instance at a time but they can be detached from one instance and then reattached to another.

EBS volumes are not linked to the instance lifecycle of one instance.

They're persistent.

If an instance moves between different EC2 hosts then the EBS volume follows it.

If an instance stops and starts or restarts the volume is maintained.

An EBS volume is created, it has data added to it and it's persistent until you delete that volume.

Now even though EBS is an availability zone based service you can create a backup of a volume into S3 in the form of a snapshot.

Now I'll be covering these in a dedicated lesson but snapshots in S3 are now regionally resilient so the data is replicated across availability zones in that region and it's accessible in all availability zones.

So you can take a snapshot of a volume in availability zone A and when you do so EBS stores that data inside a portion of S3 that it manages and then you can use that snapshot to create a new volume in a different availability zone.

For example availability zone B and this is useful if you want to migrate data between availability zones.

Now don't worry I'll be covering how snapshots work in detail including a demo later in this section.

For now I'm just introducing them.

EBS can provision volumes based on different physical storage types, SSD based, high performance SSD and volumes based on mechanical disks and it can also provision different sizes of volumes and volumes with different performance profiles all things which I'll be covering in the upcoming lessons.

For now again this is just an introduction to the service.

The last point which I want to cover about EBS is that you'll build using a gigabyte per month metric so the price of one gig for one month would be the same as two gig for half a month and the same as half a gig for two months.

Now there are some extras for certain types of volumes for certain enhanced performance characteristics but I'll be covering that in the dedicated lessons which are coming up next.

For now before we finish this service introduction let's take a look visually at how this architecture fits together.

So we're going to start with two regions in this example that's US-EAST-1 and AP-SOUTH EAST-2 and then in those regions we've got some availability zones AZA and AZB and then another availability zone in AP-SOUTH EAST 2 and then finally the S3 service which is running in all availability zones in both of those regions.

Now EBS as I keep stressing and I will stress this more is availability zone based so in the cut-down example which I'm showing in US-EAST-1 you've got two availability zones and so two separate deployments of EBS one in each availability zone and that's just the same architecture as you have with EC2.

You have different sets of EC2 hosts in every availability zone.

Now visually let's say that you have an EC2 instance in availability zone A.

You might create an EBS volume within that same availability zone and then attach that volume to the instance so critically both of these are in the same availability zone.

You might have another instance which this time has two volumes attached to it and over time you might choose to detach one of those volumes and then reattach it to another instance in the same availability zone and that's doable because EBS volumes are separate from EC2 instances.

It's a separate product with separate life cycles.

Now you can have the same architecture in availability zone B where volumes can be created and then attached to instances in that same availability zone.

What you cannot do and I'm stressing this for the 57th time small print it might not actually be 57 but it's close.

What I'm stressing is that you cannot communicate cross availability zone with storage.

So the instance in availability zone B cannot communicate with and so logically cannot attach to any volumes in availability zone A.

It's an availability zone service so no cross AZ attachments are possible.

Now EBS replicates data within an availability zone so the data on a volume it's replicated across multiple physical devices in that AZ but and this is important again the failure of an entire availability zone is going to impact all volumes within that availability zone.

Now to resolve that you can snapshot volumes to S3 and this means that the data is now replicated as part of that snapshot across AZs in that region so that gives you additional resilience and it also gives you the ability to create an EBS volume in another availability zone from this snapshot.

You can even copy the snapshot to another AWS region in this example AP - Southeastern -2 and once you've copied the snapshot it can be used in that other region to create a volume and that volume can then be attached to an EC2 instance in that same availability zone in that region.

So that at a high level is the architecture of EBS.

Now depending on what course you're studying there will be other areas that you need to deep dive on so over the coming section of the course we're going to be stepping through the features of EBS which you'll need to understand and these will differ depending on the exam but you will be learning everything you need for the particular exam that you're studying for.

At this point that's everything I wanted to cover so go ahead finish this lesson and when you're ready I look forward to you joining me in the next.

Eine neue Studie stellt fest, dass nach einem Überschreiten der 1,5°-Grenze eine Rückkehr zu niedrigeren Temperaturen nicht so realistisch ist, wie es vielfach, auch in den Sachstandsberichten des IPCC, angenommen wird. Außerdem würden die erhöhten Temperaturen viele Ökosysteme irreversibel verändern.

It appears that we are still in the period where all intellectual arts—music, mathematics, war tactics, etc—are expressions of one and the same phenomenon of the mind, and work off of each other, than the artificial separations of Chemistry and other disciplines we see later.

Il manque une lettre : description

There are a variety of important, ethical pedagogies that don't involve imposing one's political views on your students, as this author suggests.

This seems narrow to me: teaching contributes to agency and learning in many ways beyond critiquing power structures, .e.g by enhancing attention, calling into question implicit cognitive biases, equipping students with habits and tools that allow them to extract greater meaning or probe hidden assumptions from all kinds of texts. In my view, it would be a consequential reduction to understand all of this only in terms of critiquing oppressive power structures.

This terrifies me! I always have screens in the classroom because we are so often watching clips, but I am afraid of all our screenified minds and want to resist the dissolution of rectangles in general...

Interesting that class is missing here, when the digital divide remains a real challenge to online access....

of course education is not alone - almost every sphere of humanistic knowledge has been eclipsed by the logic of data analytics.
