Local Lambda Development with CDK and SAM

Testing serverless applications in the cloud can feel slow and repetitive. Waiting for builds, deployments, and cloud logs to sync interrupts your focus and slows down your development cycle. By running your functions on your local machine, you can test changes instantly, catch errors early, and build confidence before you deploy. This course teaches you how to bridge the gap between infrastructure as code and local execution. You will start with the foundational concepts of serverless architecture, understanding how cloud resources interact and why local emulation is essential. From there, you will learn to define your infrastructure using modern CDK patterns and seamlessly invoke those resources locally using SAM. This approach gives you the best of both worlds: robust infrastructure definitions and rapid, local iteration. What you'll learn: - Understand the core principles of serverless architecture and local emulation - Configure your local development environment for CDK and SAM integration - Define serverless infrastructure using modern CDK constructs and best practices - Invoke and test Lambda functions locally with mock event payloads - Debug running Lambda functions locally to find and fix errors quickly - Prepare and package your serverless application for secure cloud deployment This course is structured to take you from foundational serverless concepts to a fully functional local development workflow. You will progress from writing basic functions to mocking complex event sources and debugging code step-by-step. This course is designed for beginner serverless developers, cloud engineers, and backend developers who want to improve their local development workflow. No prior experience with SAM or CDK is required, though basic familiarity with cloud concepts and programming is helpful.
