Trying to, yes.
Let's see ...
EBS volumes seem to vary in speed. Some are relatively fast. Some are really
slow. Some fast ones become slow randomly. Some are fast attached to one
instance, but really slow attached to another.
Fast being a relative term, though. The fast ones seem to be able to do maybe
400 random IOPS. And of course you can only get about 80MB/sec sequential
access to them on a good day.
Which is why I'm interested in how other people are doing it. So far EC2
doesn't seem well suited to running databases at all.
