AMI stands for Amazon Machine Image. It is effectively a snapshot of the root filesystem. AWS AMI provides the information required to launch an instance, which is a virtual server in the cloud. You specify an AMI when you launch an instance, and you can launch as MANY instances from the AMI as you need. You can also launch instances from as many different AMIs as you need.

An AMI INCLUDES the following:

• A template for the root volume for the instance (such as an operating system, an application server, and APPLICATIONS).
• Launch permissions that control which AWS accounts can use the AMI to launch instances.
• A block device mapping that specifies the volumes to attach to the instance when it’s LAUNCHED.

Build a new AMI by first spinning up and instance from a trusted AMI. Then adding packages and components as required. Be wary of putting sensitive data onto an AMI. For instance your access credentials should be added to an instance after spin up. With a database, mount an outside volume that HOLDS your Mysql data after spin up as well.
