AWS Lambda Dependency Management and Event Handling with SAM CLI

Building serverless applications requires more than just writing basic functions; you must also manage external libraries and handle complex event data. This text-only course guides you through the process of structuring dependencies and processing events in AWS Lambda. You will transition from writing simple, isolated scripts to developing robust, event-driven serverless applications. By reading through practical, step-by-step written explanations and analyzing real-world code snippets, you will master the mechanics of the AWS Serverless Application Model (SAM) CLI to build, package, and test your functions. What you'll learn: • Understand foundational serverless concepts, Lambda execution environments, and the AWS SAM specification. • Configure external dependencies and package them efficiently using AWS Lambda Layers. • Analyze and process diverse AWS event sources, including API Gateway requests and S3 triggers. • Test and debug event-driven Lambda functions locally on your machine using the SAM CLI. • Apply modern infrastructure-as-code principles to define and deploy serverless resources. The course begins with core terminology and the fundamentals of serverless architecture. You will then progress through structured text lessons covering dependency isolation, event payload structure, and local emulation techniques for seamless development. This course is designed for beginning developers and cloud enthusiasts who want to learn serverless development on AWS. No prior experience with AWS Lambda or SAM CLI is required.
