Infrastructure as Code for Beginners (AWS CDK)

Learn Infrastructure as Code (IaC) by building a real project: a serverless REST API on AWS using the Cloud Development Kit (CDK) with Python. We'll start by manually clicking through the AWS console to set up DynamoDB, Lambda, and API Gateway (yes, there's a click counter) so you can feel the pain. Then we rebuild the entire thing using AWS CDK, deploy it with one command, test it live, and tear it all down when we're done.
