What is EC2 Launch Template?
An Amazon EC2 Launch Template is a resource used to specify the configuration details for launching instances (virtual servers) in the Amazon Elastic Compute Cloud (EC2). Launch templates simplify the process of launching instances by providing a predefined set of instance configuration parameters. This includes the Amazon Machine Image (AMI), instance type, key pair, security groups, and other settings. Learn more about EC2 Launch Template – Key Components, Benefits & Use Cases here.
