- samcheng 10y agoDoes that bring performance or cost savings? What is the motivation and calculus for making that transition?
- eliribble 10y agoIt can bring a cost savings, but the savings is very slight if you're comparing apples-to-apples. For example, if you're using RDS in a multi-AZ replication set up with periodic S3 backups you have to take into account running each of the replica instances and the S3 costs. What we found was that RDS was treated like a black box to our automation (which was a good thing for a long time) and so we were less attentive to being over-provisioned and actually testing failover situations than we should have been.
- eliribble 10y agoYes, we did move to a regular EC2 instance for our cloud service. Where we install databases on premises for our customers it can be bare iron, but it can also be a similar virtualized setup.
