Local AWS Lambda Development: Setting Up AWS SAM CLI and Docker

Transitioning to serverless development often feels challenging when you cannot easily test your code locally. Setting up a reliable local environment is the crucial first step to rapid development and debugging of AWS Lambda functions. This text-only course guides you through configuring your local machine for serverless engineering. You will transition from manual console testing to a robust, local-first workflow using industry-standard tools, enabling you to write and validate serverless code quickly and confidently. What you'll learn: Understand the core concepts of serverless architecture, AWS Lambda, and local emulation; Install and configure AWS CLI and AWS SAM CLI for secure local-to-cloud communication; Set up Docker to emulate the AWS Lambda runtime environment locally on your machine; Manage Python environments and dependencies using modern virtual environment best practices; Write, test, and debug Lambda functions locally using the SAM command-line interface; Implement structured logging and basic configuration management for local serverless development. You will begin by learning foundational serverless terminology and AWS architecture basics. From there, you will follow step-by-step written guides to install, configure, and integrate each tool, culminating in running and testing your first local Lambda function. This course is designed for beginner developers, cloud enthusiasts, and software engineers new to AWS serverless development. No prior experience with AWS SAM or Docker is required, though basic command-line familiarity is helpful. Start building and testing serverless applications locally today.
