AWS Graviton2); for memory with the arrival of DDR5 and High Bandwidth Memory (HBM) on-processor; for storage including new uses for 3D Xpoint as a 3D NAND accelerator; for networking with the rise of QUIC and eXpress Data Path (XDP); and so on. I also wrote about these topics in detail for my recent [Systems Performance 2nd Edition] book.

As I discussed in my re:Invent keynote earlier this month, I am now happy to announce the immediate availability of Amazon RDS Cross Region Read Replicas , which is another important enhancement for our customers using or planning to use multiple AWS Regions to deploy their applications. Cross Region Read Replicas are available for MySQL 5.6

To achieve concurrency control, we implemented Amazon ECS using one of Amazon’s core distributed systems primitives: a Paxos-based transactional journal based data store that keeps a record of every change made to a data entry. As you can see, the latency remains relatively jitter-free despite large fluctuations in the cluster size.

As a MongoDB user, it’s crucial to ensure that your data is safe and secure in the event of a disaster or system failure. Regular database backups are essential to protect against data loss caused by system failures, human errors, natural disasters, or cyber-attacks. Why are MongoDB database backups important?

As a part of that process, we also realized that there were a number of latency sensitive or location specific use cases like Hadoop, HPC, and testing that would be ideal for Spot.
