Building Serverless APIs with AWS Lambda and DynamoDB

Modern web development is moving away from managing complex servers to building event-driven backend systems. Understanding how to securely connect API Gateway, AWS Lambda, and DynamoDB is a foundational skill for any modern cloud developer. This written course guides you through the process of designing and deploying a fully functional serverless API backend. You will learn how to handle HTTP requests, process data with serverless functions, and safely query a NoSQL database while adhering to modern security and permission standards. What you'll learn: - Understand the core architecture of serverless systems using API Gateway and AWS Lambda - Configure secure IAM roles and policies using the principle of least privilege - Write clean Lambda functions to query and retrieve data from DynamoDB tables - Map HTTP requests to backend serverless logic using API Gateway integrations - Apply modern structured logging and error-handling practices to troubleshoot serverless applications - Test your serverless API endpoints using structured text-based scenarios The course begins with foundational serverless concepts and essential terminology, then moves step-by-step through setting up permissions, writing database queries, and configuring API endpoints. You will work through detailed code snippets and conceptual explanations to build a reliable read-and-write data flow. This course is designed for beginner developers, system administrators, and cloud enthusiasts who want to learn serverless development from scratch. No prior AWS experience is required.
