Amazon Machine Images (AMI) Overview

An Amazon Machine Image (AMI) provides the information required to launch an EC2 instance.  

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:

  1. A template for the root volume for the instance (for example, an operating system, an application server, and applications)

  2. Launch permissions that control which AWS accounts can use the AMI to launch instances

  3. A block device mapping that specifies the volumes to attach to the instance when it's launched

AMIs are regional. Can launch an AMI only from the region in which it is stored. Can however store AMI to other regions using console, command line or the EC2 API.

About is my blog to share notes and learning materials on Cloud and Data Analytics. My current focus is on Amazon Web Services.

I like to write. I try to document what I learn and share with others. I believe that knowledge is useless unless you share it; the more you share, the more you learn.
