Hey Dan, interesting to hear your experiences with EC2, especially with RDS - Would you mind expanding on your comment:
"EBS would fail often too"
How often is often, and in what way did it fail ?
I'm currently thinking about using RDS in a production environment and it would be interesting to know the limitations.
- crazygringo 13y agoIt's in the AWS docs -- basically, EBS (and RDS built on top of it) is more reliable than a standard hard drive, but nothing like S3 -- you need to expect RDS to fail eventually, just like you would with a server of your own. But, that's why AWS gives you RDS backups, AZ failover, etc. -- the backups won't fail (they're stored on S3), and with AZ failover, you can make downtime vanishingly small. But you need to actually do that. A lot of people seem to confuse S3's 99.9999...% reliability with the EBS-backed stuff, which you must plan for eventual failure with.
