In the last four weeks, we moved most of the cache workload from AWS S3 to our own Cassandra cluster.

After testing whether Prerender pages could be cached in both S3 and minio, we slowly diverted traffic away from AWS S3 and towards minio.

Phase 1 mostly involved setting up the bare metal servers and testing the migration on a small and more manageable setting before scaling. This phase required minimal software adaptation, which we decided to run on KVM virtualization on Linux.

The solution? Migrate the cached pages and traffic onto Prerender’s own internal servers and cut our reliance on AWS as quickly as possible.
