April 30, 2012, 6:15 AM — For many MySQL database admins, Amazon Web Services represents the brave new world of cloud computing -- one fraught with disappearing servers, disk I/O variability, and other shared resource challenges, not to mention questions regarding the security of data.
But for those seeking to tap the powerful flexibility that cloud computing affords MySQL database deployments, AWS should be viewed simply as the next natural step in data center evolution -- one in which virtualization and commodity hardware are a given, and scalability, performance, and high availability are readily attained.

To help DBAs take advantage of what Amazon.com offers, we've compiled the following primer on managing MySQL databases in Amazon's cloud. Along the way, you'll find essential tools and techniques for migrating databases to AWS, tuning them for high performance and high availability, and avoiding the pitfalls of computing in the cloud.
Demystifying deployment and disappearing serversOf all the steps to ensure a successful AWS deployment, spinning up a basic instance is the simplest. More challenging is dealing with the new reality of disappearing servers.
To get started, download the Amazon API tools and install. Next set up your environment variables (EC2_HOME, EC2_PRIVATE_KEY, EC2_CERT; you may also need to set JAVA_HOME and PATH), spin up your instance, fetch the name of your new instance, and connect:
$ ec2-run-instances ami-31814f58 -k my-keypair -t t1.micro$ ec2-describe-instances$ ssh -i my-keypair email@example.com
Next you'll want to set up MySQL and a few base packages. Here we recommend the Percona free edition of MySQL:
