- It can (typically) include launch permissions that control which AWS accounts can use the AMI to launch instances.
- It can (typically) include a block device mapping that specifies the volumes to attach to the instance when it's launched.
- It can (typically) be associated with an AMI ID.
- It can range from being an Native AMI to being a Custom AMI.
