AWS CDK Construct Layers Explained: L1 vs L2 vs L3

In this video, we’ll walk through the three layers of AWS CDK constructs—L1 (raw CloudFormation), L2 (service-level abstractions), and L3 (patterns). You’ll see side-by-side code examples showing how each layer deploys the same API + Lambda, learn the benefits and trade-offs of each approach, and understand when to use them in real-world projects.
