Each EC2 instance comes with a certain amount of transient storage. It is transient because it does not persist beyond instance termination. Amazon also has persistent storage for your EC2 instances called Elastic Block Store. EBS volumes will persist beyond instance termination and can be attached to any running instance (but only one at once) within the same availability zone. If you're running MySQL on EC2, it's pretty straightforward. You get an EBS volume for your database and back that volume up to Amazon's S3 service. S3 will then provide multi-site redundancy for your data in the event of AWS availability zone failure.
