The AWS CDK is an infrastructure modeling framework that allows you to define your cloud resources using an imperative programming interface.

The AWS CDK is an infrastructure modeling framework that allows you to define your cloud resources using an imperative programming interface, currently TypeScript/JavaScript, Python, Java, C# and (beta) Go.

Developers can use one of the supported programming languages to define reusable cloud components called Constructs, which are composed together into Stacks and Apps.

The AWS CDK Toolkit is a command-line tool for interacting with CDK apps. It allows developers to synthesize artifacts such as AWS CloudFormation Templates, deploy stacks to development AWS accounts and “diff” against a deployed stack to understand the impact of a code change.

The AWS Construct Library includes a module for each AWS service with constructs that offer rich APIs that encapsulate the details of how to use AWS. The AWS Construct Library aims to reduce the complexity and glue-logic required when integrating various AWS services to achieve your goals on AWS.
