SimpleDB is not an RDBMS. It has very specific use-cases where it makes sense, and most database use does not fit into those use-cases. Perhaps you're thinking of Amazon RDS, which is their managed MySQL/Oracle/SQL Server deployments. RDS is very expensive compared to running your own database, even on the very same EC2/EBS platform -- but you get reliability, replication and backups that some employee would have to be managing otherwise. In theory, at least. RDS didn't live up to its promises when I used it, so I moved back to running databases on physical servers at half the cost.
- genwin 14y agoPlease elaborate on how RDS didn't live up to its promises?
- dangrossman 14y agoWhen EBS failed in US-East a year or two ago, my RDS instance did not remain available and did not automatically fail over to its replica, despite my paying for these benefits. Even when it was working correctly, the RDS instances had low capacity compared to physical servers, and there were often spikes of significant latency that would lead to overloaded web servers as DB queries backed up unanswered.
- genwin 14y agoGood to know. I read here on HN that during the storm event in June, the same thing happened (no auto fail over for those who paid for it).
