Serverless API Development with AWS Lambda and YAML Configuration

Building scalable APIs no longer requires managing complex server infrastructure. By using AWS Lambda and the Serverless Framework, you can deploy powerful applications using simple configuration files. This text-only course guides you through the core concepts of serverless architecture, helping you transition from traditional server management to writing clean, configuration-driven APIs. You will learn how to map routes to Lambda functions and manage deployments efficiently. What you'll learn: Understand foundational serverless concepts and AWS Lambda execution models; Configure API routes and HTTP event triggers using Serverless YAML syntax; Apply secure environment variable management to your serverless configurations; Implement basic IAM permissions following the principle of least privilege; Structure configuration files for clean, maintainable infrastructure-as-code; Test and debug serverless routing configurations through written code exercises. The course starts with essential terminology and the basics of serverless architecture. You will then progress through step-by-step written guides and configuration exercises, learning to write, deploy, and refine Serverless YAML files. This course is designed for beginner developers, cloud enthusiasts, and backend engineers new to serverless deployment. No prior AWS or Serverless Framework experience is required.
