Cloud Computing Advanced

What is CDK (Cloud Development Kit)?

A software development framework for defining cloud infrastructure using familiar programming languages instead of YAML or JSON templates.

AWS CDK lets developers define cloud infrastructure using TypeScript, Python, Java, C#, or Go instead of writing CloudFormation YAML. Infrastructure becomes real code — with loops, conditions, abstractions, and testing.

CDK constructs represent cloud resources at different abstraction levels. L1 constructs map directly to CloudFormation. L2 constructs add sensible defaults. L3 constructs (patterns) represent complete architectures. CDK synthesizes to CloudFormation templates for deployment.
