The AWS CDK is an infrastructure modeling framework that allows you to define your cloud resources using an imperative programming interface. The CDK is currently in developer preview. We look forward to community feedback and collaboration.

If you’re developing for AWS and using CloudFormation, and you feel that YAML and/or JSON templates are too restrictive, CDK will allow you to programmatically define your stack. CDK provides strong typed resources for Java, .Net, and TypeScript, as well as JavaScript support. You can even augment it by creating your own constructs and create your own DSL on top of CloudFormation!
