Creating CloudFormation templates

In this section, we present the recipe to create an AWS CloudFormation template to specify the AWS resources (and their properties). AWS CloudFormation provides editors to help you to edit your CloudFormation templates. These editors are available for both Visual Studio (AWS Toolkit for Visual Studio) and Eclipse (AWS Toolkit for Eclipse) environments. Based on your application-specific requirements, you will need to define parameters, mappings, resources, and output in the template. Image ID, instance type, VPC ID, subnet IDs, a name for the instance, and key/pair names are the required parameters to run this recipe. You can store this template file in a local folder or in S3 storage. Before creating the stack from the template, you should validate the template using CLI.
