AWS CDK

The AWS CDK lets you build reliable, scalable, cost-effective applications in the cloud with the considerable expressive power of a programming language. This approach yields many benefits, including:

Build with high-level constructs that automatically provide sensible, secure defaults for your AWS resources, defining more infrastructure with less code.
Use programming idioms like parameters, conditionals, loops, composition, and inheritance to model your system design from building blocks provided by AWS and others.
Put your infrastructure, application code, and configuration all in one place, ensuring that at every milestone you have a complete, cloud-deployable system.
Employ software engineering practices such as code reviews, unit tests, and source control to make your infrastructure more robust.
Connect your AWS resources together (even across stacks) and grant permissions using simple, intent-oriented APIs.
Import existing AWS CloudFormation templates to give your resources a CDK API.
Use the power of AWS CloudFormation to perform infrastructure deployments predictably and repeatedly, with rollback on error.
Easily share infrastructure design patterns among teams within your organization or even with the public.
