Create Amazon EC2 resources using AWS CloudFormation
Amazon EC2 is integrated with AWS CloudFormation, a service that helps you to model and set up your AWS resources so that you can spend less time creating and managing your resources and infrastructure. You create a template that describes the AWS resources that you need (such as instances and subnets), and CloudFormation provisions and configures those resources for you.
When you use CloudFormation, you can reuse your template to set up your Amazon EC2 resources consistently and repeatedly. Describe your resources once, and then provision the same resources over and over in multiple AWS accounts and Regions.
Amazon EC2 and CloudFormation templates
To provision and configure resources for Amazon EC2 and related services, you must understand CloudFormation templates. Templates are formatted text files in JSON or YAML. These templates describe the resources you'll provision in your CloudFormation stacks. If you're unfamiliar with JSON or YAML, you can use CloudFormation Designer to help you get started with CloudFormation templates. For more information, see What is CloudFormation Designer? in the AWS CloudFormation User Guide.
