# EC2 Launch Template Version

An EC2 Launch Template Version in AWS defines a specific configuration of an EC2 launch template, including details like instance type, AMI, key pairs, security groups, and network settings. Each version is immutable, allowing you to maintain multiple versions of a template for different use cases or environments. This makes it easier to manage, update, and roll back EC2 instance configurations consistently and reliably.
