Using MySQL within an Amazon EC2 Instance
The Amazon Elastic Compute Cloud (EC2) service provides virtual servers that you can build and
deploy to run a variety of different applications and services, including MySQL. The EC2 service is
based around the Xen framework, supporting x86, Linux based, platforms with individual instances of
a virtual machine referred to as an Amazon Machine Image (AMI). You have complete (root) access
to the AMI instance that you create, enabling you to configure and install your AMI in any way you
choose.
To use EC2, you create an AMI based on the configuration and applications that you intend to use,
and upload the AMI to the Amazon Simple Storage Service (S3). From the S3 resource, you can
deploy one or more copies of the AMI to run as an instance within the EC2 environment. The EC2
environment provides management and control of the instance and contextual information about the
instance while it is running.
Because you can create and control the AMI, the configuration, and the applications, you can deploy
and create any environment you choose. This includes a basic MySQL server in addition to more
extensive replication, HA and scalability scenarios that enable you to take advantage of the EC2
environment, and the ability to deploy additional instances as the demand for your MySQL services and
applications grow.
To aid the deployment and distribution of work, three different Amazon EC2 instances are available,
small (identified as m1.small), large (m1.large) and extra large (m1.xlarge). The different types
provide different levels of computing power measured in EC2 computer units (ECU). A summary of the
different instance configurations is shown in the following table.
