Nothing. I have created a Postgres instance on an EC2 virtual machine with
attached EBS(Elastic Block Storage). I only got as far as creating in it and
verifying it would run, no benchmarking. EC2 instances have storage as part of
the instance but it is temporary and goes away when the instance is shut down.
For a database you want EBS as it is a virtual harddrive that persists. Should
an EC2 instance go down, you just reattach the EBS drive on reboot. If I
remember correctly there are also some articles at aws.amazon.com about setting
up RAID using EBS drives.
