An Amazon Machine Image (AMI) is a template that contains the software configuration required to launch an instance. Think of it as a blueprint for your EC2 instances.

AMI Components

An AMI includes the operating system, application server, and applications. It also includes launch permissions that control which AWS accounts can use the AMI to launch instances.

AMI Types

There are different types of AMIs: Public AMIs provided by AWS and the community, My AMIs that you've created, and Marketplace AMIs that include commercial software.

AMI Storage

AMIs are stored in Amazon S3 and are region-specific. When you create an AMI from an instance, AWS automatically creates snapshots of the instance's EBS volumes.
