About AWS CDK
AWS Cloud Development Kit (CDK) is an Infrastructure as Code framework by Amazon that lets you define AWS cloud resources using TypeScript, Python, Java, C#, and Go. It provides high-level constructs that encapsulate best practices and defaults, making it easier to build production-ready AWS infrastructure. CDK supports synthesis to CloudFormation templates, allowing use of existing AWS tooling. It includes a large library of construct libraries maintained by AWS and the community.

Crossplane is an open-source Kubernetes add-on that transforms your Kubernetes cluster into a universal control plane for managing infrastructure across multiple clouds and services. Using Kubernetes CRDs, it enables platform teams to compose custom infrastructure abstractions and expose them to developers through a unified API. Crossplane supports all major cloud providers, handles resource composition, and enforces policies through Kubernetes-native mechanisms.
