AMI

An Amazon Machine Image (AMI) is a special type of virtual appliance that is used to create a virtual machine within the Amazon Elastic Compute Cloud ("EC2"). It serves as the basic unit of deployment for services delivered using EC2.

1. Public -> The owner grants launch permissions to all AWS accounts. 2. Explicit -> The owner grants launch permissions to specific AWS accounts. 3. Implicit -> The owner has implicit launch permissions for an AMI.
