What database should I use with S3 as a host?

I'm comp开发者_JAVA技巧letely new to s3. Started coding on a site today. I'm a mysql guy, but I'm not sure if I can host a mysql database on their server or what my options are. What is my best option for database storage?

Edited to add: I know this question sounds vague, but I literally don't know what my options are. Can I use a mysql database on amazon's servers or am I forced to use Amazon's SimpleDB?

S3 itself is not a typical data storage that you would simply use with RDBMS. It's only accessible via web service and is not a block device. I think that your best bet for hosting database on Amazon would be Relational Database Service which , in effect, is mysql.

You could also run your own mysql server on EC2 using EBS as backing store.

Also, SimpleDB is very nice but it is not a relational database. It's more like persistent hash map. It is not transactional and is eventually consistent. It belongs to category of No SQL solutions and you have to design your system in very specific ways for it.

S3 is a storage provider; you can't run your own code on it. You pay for file storage and can access it from your application, which has to be hosted elsewhere (Amazon EC2 for example).
