Creating an Amazon Machine Image
We have already discussed Amazon Machine Image (AMI) while creating EC2 instances. AMI is the most common way to create backup images of an EC2 Instance.

AMIs store references to device mapping with corresponding volume snapshots. AMIs can be used to define a standard template which can be used while launching EC2 instances. For example, we may want to use a standard flavor of Linux with predefined system configurations across all EC2 instances. We can create an AMI for this and use it while creating EC2 instances.
