    1. DBA Por Acaso: RDS, MySQL e Tuning para Iniciantes

      Outro assunto que não é explicitamente coberto por nossos tópicos, mas que é base importante para o administrador de sistemas na nuvem - e aqui coberto em um nível introdutório, para não assustar ninguém. E procura por Cloud em https://wiki.lpi.org/wiki/DevOps_Tools_Engineer_Objectives_V1 para ver como esse assunto é importante!

    2. Repositorio NPM privado grátis com Verdaccio e AWS

      Excelente para você entender, na prática, sobre Cloud Deployment (um de nossos importantes subtópicos!). Além disso, vai sair da palestra com mais ferramentas para seu cinto de utilidades!

    1. To return data after an asynchronous operation, return a promise.

      I just struggled for a few hours trying to resolve some errors about CORS and 500 INTERNAL errors.

      This line is a bit misleading.

      In trying to get things up and running, I was returning a simple JSON object rather than a Promise. According to what I found, even if you don't have any async work, you still need to return a Promise from your function.

    1. This page will cover creating a new box in Vagrant Cloud and how to distribute it to users. Boxes can be distributed without Vagrant Cloud, but miss out on several important features.

    1. One of the largest-scalestudies exploring this problem was undertaken at the University of Wash-ington (Fidel et al., 2000), where researchers investigated the information-seeking behavior of teams from two different companies, Boeing andMicrosoft (Poltrock et al., 2003). They found that each team had differentcommunication and information-seeking practices, and that current infor-mation systems are oriented toward individual rather than collaborativeinformation-seeking activities. In practice, though, information seeking isoften embedded in collaboration

      SBTF uses Google Sheets and Docs for information collection and shared documentation. Though Google products are billed as cloud-computing collaboration tools, it would be interesting to know if these systems remain oriented in individual information-seeking activities rather than collaborative.

    1. By eliminating cold servers and cold containers with request-based pricing, we’ve also eliminated the high cost of idle capacity and helped our customers achieve dramatically higher utilization and better economics.

      Cold servers and cold containers is a term I haven't heard before, but it sums up the waste of excess capacity nicely

    1. Figure 4: Typical diurnal cycle for traffi c in the Internet. The scale on the vertical axis is the percentage of total users of the service that are on-line at the time indicated on the horizontal axis. (Source: [21])

      I can't see an easy way to link to this graph itself, but this reference should make it easier to get to this image in future

    1. a personal computer to a server or onto theInternet. File distribution is the point of conjuncture between organismand machine and marks a technology of the self that does not begin withthe individual interior subject but rather with what Doyle calls “inhumanexteriority”

      I feel like there is something to be said about the Cloud ("the Cloud is just somebody else's computer") that could be said to expand on this point and develop it a bit further, but I don't know enough about the Cloud and file sharing to articulate what that might be . . .

    1. using Cloud based services, despite their creators best intentions has considerable risks sinceAny Cloud based approach creates massive hugely attractive fragile Honeypots

    1. Shared information

      The “social”, with an embedded emphasis on the data part of knowledge building and a nod to solidarity. Cloud computing does go well with collaboration and spelling out the difference can help lift some confusion.

    1. Apple’s superior position on privacy needs to be the icing on the cake, not their primary selling point.

      Yeah... 'cause apparently no one actually cares...

    1. Today the move to cloud computing is replicating some of that early rhetoric—except, of course, that companies now reject any analogy with utilities, since that might open up the possibility of a publicly run, publicly controlled infrastructure.

      That's a distinct possibility - if the infrastructure could be built with trust. Keep hoping.

    1. Specifically, we explore three key usage modes (see Figure 1): • HPC in the Cloud , in which researchers out - source entire applications to current public and/ or private Cloud platforms; • HPC plus Cloud , focused on exploring scenarios in which clouds can complement HPC/grid re - sources with cloud services to support science and engineering application workflows—for ex - ample, to support heterogeneous requirements or unexpected spikes in demand; and • HPC as a Service , focused on exposing HPC/grid resources using elastic on-demand cloud abstrac - tions, aiming to combine the flexibility of cloud models with the performance of HPC systems

      Three key usage modes for HPC & Cloud:

      • HPC in the Cloud
      • HPC plus Cloud
      • HPC as a Service

    1. Clouds establish a new division of responsibilities between platform operators and users than have trad itionally e x- isted in computing infrastructure. In private clouds, where all participants belong to the same organization, this cr e- ates new barriers to effective communication and resource usage. In this paper, we present poncho , a tool that i m- plements APIs that enable communication between cloud operators and their users, for the purposes of minimizing impact of administrative operations and load shedding on highly - utilized private clouds.

    2. One of the critical pieces of infrastructure provided by this system is a mechanism that can be used for load shedding, as well as a way to communicate with users when this action is required . As a building block, load shedding enables a whole host of more advanced r e- source management capabilities, like spot instances, advanced reservations, and fairshare scheduling
