Cloud applications are built using multiple components, such as virtual servers, containers, serverless functions, storage buckets, and databases. Being able to provision and configure these resources in a safe, repeatable way is incredibly important to automate your processes and let you focus on the unique parts of your implementation.

With the AWS Cloud Development Kit (AWS CDK), you can leverage the expressive power of your favorite programming languages to model your applications. You can use high-level components called constructs, preconfigured with “sensible defaults” that you can customize, to quickly build a new application. The CDK provisions your resources using AWS CloudFormation to get all the benefits of managing your infrastructure as code. One of the reasons I like the CDK, is that you can compose and share your own custom components as higher-level constructs.

As you can imagine, there are recurring patterns that can be useful to more than one customer. For this reason, today we are launching the AWS Solutions Constructs, an open source extension library for the CDK that provides well-architected patterns to help you build your unique solutions. CDK constructs mostly cover single services. AWS Solutions Constructs provide multi-service patterns that combine two or more CDK resources, and implement best practices such as logging and encryption.
