API Gateway for Lambda Endpoints

Build scalable and secure RESTful APIs by integrating AWS Lambda with Amazon API Gateway, handling authentication and request/response mapping.

API Gateway & Lambda: The Duo

Welcome! In this lesson, we'll connect AWS Lambda with Amazon API Gateway. This powerful combination lets you build scalable, serverless APIs without managing any servers.

Think of API Gateway as the front door for your applications, routing requests to the right backend service, often a Lambda function.

Why Use API Gateway?

API Gateway offers several benefits when exposing Lambda functions:

  • Scalability: Handles thousands of concurrent API calls.
  • Traffic Management: Manages traffic, including throttling and caching.
  • Security: Provides built-in authentication and authorization.
  • Monitoring: Integrates with CloudWatch for logging and monitoring.
