AWS Cloud Development Kit (CDK) is an open-source software development framework for defining AWS cloud infrastructure using general-purpose programming languages, provisioned through AWS CloudFormation. Developers write reusable components called constructs in TypeScript, Python, Java, C#/.NET, or Go, then use the CDK CLI to synthesize, diff, and deploy CloudFormation stacks.
Developers and teams already building on AWS who want to define infrastructure with a general-purpose programming language instead of authoring CloudFormation YAML or JSON templates directly.
A constructs library covering AWS services, the CDK CLI (synth, diff, deploy, drift), and access to Construct Hub for discovering and sharing community and vendor construct packages.
CDK apps written in a supported language define constructs that are synthesized into AWS CloudFormation templates; the CDK CLI then deploys those templates as CloudFormation stacks, which CloudFormation provisions and tracks.
