No, this doesn't imply SSDs.
EC2 instances do not have access to SSDs but to EBS volumes which is a much slower distributed network block storage medium.
Not sure about their PostgreSQL replication issues but lots of companies manage to make it work without a hitch.
- ActorNightly 9mo agoYou can have EC2s with ssds. But generally the workflow for running your own DB is smart caching in memory on top of whatever storage you got.
- LunaSea 9mo agoThe problem with the metal instances you are referring to is that the SSD is lost if you stop and start the server.
