What is an Amazon Machine Image (AMI)?

One of the most powerful features of AMIs is their pre-configured instances. These pre-configured images let IT professionals launch things like EC2 instances much more quickly. For instance, an AMI might come preconfigured for everything needed to run a LAMP stack. By using this AMI, developers don't need to install Apache, MySql, or PHP. Likewise, things like the services and firewalls are already configured. Developers only need to worry about fine-detail configurations.

AMIs aren't only for AWS pre-configured images, though. Organizations can create their own images as well. With AMI, you can launch multiple instances with the same image, as long as the configuration for both is the same. An AMI can include a combination of the following:

Amazon Elastic Block Store (EBS) snapshots, or a template for the root volume of an instance in the case of instance-store-backed AMIs.

A set of launch permissions, which determine which AWS accounts can access both the AMI and the instances that it launches.

A block device mapping, which lists the volumes that will get attached to the instance after it launches.

You can make AMIs private so that no one else can use them. You can also share it with other AWS accounts or make it public so that the entire AWS community can use it. You can even buy and sell AMIs.
