AWS API Gateway Foundations for Lambda and Step Functions

Connecting client applications to backend services securely and efficiently is a core requirement of modern cloud architecture. AWS API Gateway acts as the entry point, seamlessly routing traffic to serverless compute and orchestration tools. This text-based course guides you through the foundational concepts of API Gateway, helping you understand how to design, configure, and manage APIs. You will learn how to handle incoming requests, integrate them with Lambda functions and Step Functions, and choose the right API type for your specific workload. What you'll learn: - Understand the core differences between HTTP APIs and REST APIs to make informed architectural decisions. - Configure API Gateway routes to trigger Lambda functions and pass request data seamlessly. - Integrate API Gateway with Step Functions to orchestrate complex, multi-step serverless workflows. - Apply modern security practices, including basic authorization and API keys, to protect your endpoints. - Monitor API performance and troubleshoot errors using modern logging and observability practices. You will start with fundamental API concepts and terminology before moving on to structured configuration scenarios. Through clear written explanations, architectural breakdowns, and structured code snippets, you will learn how to deploy, secure, and maintain your APIs. This course is designed for backend developers, cloud beginners, and aspiring solutions architects with no prior API Gateway experience.
