Amazon Relational Database Service (Amazon RDS) : Amazon is offering MySQL in the cloud.
Amazon RDS gives you access to the full capabilities of a familiar MySQL database. This means the code, applications, and tools you already use today with your existing MySQL databases work seamlessly with Amazon RDS. Amazon RDS automatically patches the database software and backs up your database, storing the backups for a user-defined retention period
Joe points out that this is kinda spendy, as they’re really just running MySQL on an EC2 image, just like you’re able to do yourself.
