Proactively validate your AWS CloudFormation templates with AWS Lambda

AWS CloudFormation is a service that allows you to define, manage, and provision your AWS cloud infrastructure using code. To enhance this process and ensure your infrastructure meets your organization’s standards, AWS offers CloudFormation Hooks. These Hooks are extension points that allow you to invoke custom logic at specific points during CloudFormation stack operations, enabling you to perform validations, make modifications, or trigger additional processes. Among these, the Lambda hook is a powerful option provided by AWS. This managed hook allows you to use Lambda functions to validate your CloudFormation templates before deployment. By using a Lambda hook, you can invoke custom logic to check infrastructure configurations on create or update or delete CloudFormation resources or stacks or change sets, as well as create or update operations for AWS Cloud Control API (CCAPI) resources. This enables you to enforce defined policies for your infrastructure-as-code (IaC), preventing the deployment of non-compliant resources or emitting warnings for potential issues. In this blog post, you will explore how to use a Lambda hook to validate your CloudFormation templates before deployment, ensuring your infrastructure is compliant and secure from the start...
