AWS API Gateway

Imagine we're running a shopping mall with various stores (services). Each store has a specific way of handling customer requests, such as ordering products or checking inventory. Instead of letting customers interact with each store directly, which could be confusing and inefficient, we create a central information desk (API Gateway) that handles all incoming requests and forwards them to the right store.

AWS API Gateway is like that central information desk. It acts as a front door for our API and allows us to define how incoming requests should be handled, authenticated, and routed to different back-end services, such as AWS Lambda functions or Step Functions. This way, we can create a standardized, secure, and scalable way for our users to interact with our services.
