Serverless Integration with AWS CDK: Connecting API Gateway to Lambda

Modern cloud development relies on building scalable, decoupled applications without the overhead of managing physical servers. Connecting an API Gateway to a Lambda function is the foundational pattern for serverless web applications and microservices. This text-based course guides you through understanding, writing, and deploying this essential architecture using the AWS Cloud Development Kit (CDK). You will transition from manually configuring cloud resources in a web console to writing clean, maintainable infrastructure-as-code. By reading through real-world configuration patterns, you will learn how to design secure and highly available endpoints. What you'll learn: - Understand the core concepts of serverless architecture, API Gateway endpoints, and Lambda execution environments - Write infrastructure-as-code using modern AWS CDK patterns to define cloud resources - Configure secure API Gateway integrations to route HTTP requests directly to backend Lambda functions - Manage environment variables, IAM roles, and execution permissions with least-privilege security principles - Apply modern observability practices by setting up basic logging and structured monitoring for your serverless stack - Deploy and test your stack using the CDK Command Line Interface (CLI) The course begins with foundational concepts of serverless computing and infrastructure-as-code before walking you through step-by-step configuration examples, resource provisioning, and deployment validation. This course is designed for backend developers, cloud enthusiasts, and DevOps beginners who want to learn programmatic cloud deployment. No prior experience with AWS CDK or serverless architecture is required.
