Local AWS Lambda Testing and Serverless Emulation

Developing serverless applications often feels slow when you have to deploy to the cloud for every single change. Emulating your serverless environment locally allows you to debug quickly, save on cloud costs, and speed up your development cycle. This text-based course guides you through setting up and running AWS Lambda functions on your own computer so you can test your code with confidence before it ever reaches production. You will start with the absolute basics of serverless architecture, learn how local emulation works, and progress to simulating real-world cloud events. What you will learn: Understand the core concepts of serverless architecture and local emulation; Configure AWS SAM to define and package your serverless resources; Run and debug AWS Lambda functions locally using the Lambda Test Tool; Simulate API Gateway events and trigger functions with mock payloads; Write automated tests for your local serverless functions using pytest; Prepare your validated local configurations for seamless deployment to AWS. The course begins with foundational definitions and key serverless terminology, moves into step-by-step local setup, and concludes with practical testing strategies. This course is designed for beginner backend developers, cloud enthusiasts, and software engineers who are new to serverless development and want to learn local emulation from scratch.
