AWS Lambda Development and Troubleshooting for Beginners

Serverless architecture offers incredible scalability, but debugging and maintaining AWS Lambda functions can feel like searching for a needle in a haystack without the right tools. Understanding how to properly configure, monitor, and troubleshoot your serverless code is essential for building resilient cloud applications. This text-based course guides you from serverless basics to confident troubleshooting. You will learn how to interpret system logs, identify performance bottlenecks, and resolve deployment errors using industry-standard tools and modern observability workflows. What you'll learn: 1. Understand foundational serverless concepts and AWS Lambda execution environments. 2. Configure CloudWatch to capture, filter, and analyze runtime logs and metrics. 3. Debug Lambda execution errors and handle cold starts and timeouts effectively. 4. Apply CFN Lint to validate CloudFormation templates and prevent deployment failures. 5. Implement modern observability practices, including structured JSON logging and distributed tracing. 6. Write clean, testable serverless code using local testing strategies. You will start with core serverless definitions and architecture before moving into practical debugging scenarios, log analysis, and automated template validation. The course wraps up with modern monitoring strategies to keep your production functions running smoothly. This course is designed for software developers, system administrators, and cloud beginners who want to build and maintain reliable AWS Lambda functions. No prior serverless experience is required.
