Building Serverless APIs with AWS Lambda and YAML

Modern application development relies heavily on cloud-native architectures that scale automatically without the burden of server management. This text-based course guides you through the foundational concepts of serverless computing, focusing on how to build robust APIs using AWS Lambda and configuration-driven deployment. By reading and working through the structured explanations, you will transition from understanding basic cloud functions to deploying fully functional, secure APIs. You will learn how to structure your application configuration, manage routing, and handle data flow efficiently. What you'll learn: 1. Understand core serverless concepts and AWS Lambda execution models. 2. Configure serverless applications using YAML syntax for infrastructure as code. 3. Build and deploy REST APIs integrated with AWS Lambda functions. 4. Manage security permissions using foundational AWS IAM roles and policies. 5. Implement structured logging and modern debugging practices for cloud functions. 6. Design scalable API routes and handle HTTP requests and responses effectively. The course begins with essential serverless terminology and AWS fundamentals before guiding you through hands-on YAML configuration. You will progress through step-by-step written tutorials that demonstrate how to connect API endpoints to Lambda functions and deploy your solution to the cloud. This course is designed for beginner developers, cloud enthusiasts, and software engineers looking to transition to serverless architectures. No prior AWS or infrastructure experience is required.
