AMIs and Launch Template

AMIs (Amazon Machine Images) store information such as the operating system, applications, and settings in the EC2 instance from which they are created. Creating an AMI ensures that when new servers are launched, they are identical and can operate immediately.

A launch template is a tool we use to configure the initialization of new EC2 instances through attached AMIs, instance types, network configurations, and security options. When we want to launch one or more identical servers, we simply use the configured launch template to do so.
