In addition to the basic infrastructure as code capabilities provided by AWS CloudFormation, AWS now offers various programmability constructs to power complex provisioning use cases. In this talk, we present several advanced use cases of declarative, imperative, and mixed coding scenarios that cloud infrastructure developers can leverage. Examples include demonstrating how to create custom resources and leveraging transforms, like the AWS Serverless Application Model (AWS SAM), to create both simple and complex macros with AWS CloudFormation.
