This week’s Tech Spotlight is the AWS Cloud Development Kit (CDK). AWS CDK is an open source software development framework to model and define your cloud application resources using familiar programming languages. Developers are telling us they like that AWS CDK makes it easier to apply their existing knowledge in developing with languages such as Typescript, Javascript, Java, Python, and .NET to build cloud infrastructure within their current software development workflow.

We hear great feedback about AWS CDK’s construct programming model, which enables Developers to build constructs, or higher level components, which pre-configure cloud resources with sensible defaults. The AWS CDK team maintains AWS constructs as part of the AWS Construct Library. Another AWS project includes AWS Solutions Constructs, which are vetted architecture patterns that can be easily assembled to create production-ready workloads. There’s also CDK Patterns, an open source collection of AWS Serverless Architecture constructs that Liberty IT is sharing after building some of them initially for their own internal use.

What’s really exciting about CDK is the vibrant open source community coming together around this project. For example, while AWS CDK currently uses AWS CloudFormation to provision AWS infrastructure, AWS CDK can be adapted to work with a variety of technologies. Earlier this year an AWS team led the way with cdk8s, a framework for defining Kubernetes YAML in familiar programming languages. Similarly, members of the community, including Hashicorp., have come together to create cdk for Terraform so CDK enthusiasts can use CDK to more easily define HCL.

If you want to learn more, the community is organizing CDK Day on September 30th. It is the first-ever community-led virtual summit for everyone interested in CDK. Whether you’re new to CDK or a core maintainer, we hope you check it out!
