Transitioning from using AWS CloudFormation to developing applications with the AWS CDK can be a daunting task. Luckily, the AWS CDK offers a solution that can assist in importing and migrating existing CloudFormation templates.

Instead of manually defining these resources using their matching class, developers can utilize the AWS CDK cloudformation-include class to import a stack template and convert resource definitions to L1 constructs.

In this lab, you will use the CfnInclude class to import a predefined website-hosting Amazon S3 bucket into a CDK stack. You will also explore the configuration options available to you after the resources have been successfully imported.
