Concepts - AWS Cloud Development Kit (AWS CDK) v2

This is the AWS CDK v2 Developer Guide. The older CDK v1 entered maintenance on June 1, 2022 and will now receive only critical bug fixes and security patches. New features will be developed for CDK v2 exclusively. Support for CDK v1 will end entirely on June 1, 2023.


This topic describes some of the concepts (the why and how) behind the AWS CDK. It also discusses the AWS Construct Library.

AWS CDK apps are composed of building blocks known as Constructs, which are composed together to form stacks and apps.
