Every blog must have a database to store all its data (posts, comments, settings and so on). WordPress uses the database. Usually the database is stored locally ob the web server of the blog. In some cases one would want to have the database installed elsewhere for many reasons (loads, capacity, backups). This is where kicks in.
What is Amazon RDS?
Amazon Relational Database Service (Amazon RDS) is a web service that makes it easy to set up, operate, and scale a relational database in the cloud. That means that you can have your MySQL database operate on Amazon’s cloud computers located all over the world. Just like they say:
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. You also benefit from the flexibility of being able to scale the compute resources or storage capacity associated with your relational database instance via a single API call.
According to Amazon there is no need to make any changes to your application in order to use Amazon RDS. Well, at least for WordPress and WordPress-MU they are right.
A standard WordPress installation, using Amazon RDS, is located at and a WordPress-MU (the kind of WordPress that uses) is located at . I will keep this installation alive for a few days and then take it down since the use of Amazon RDS is not free.
