AWS API Gateway Overview

Amazon API Gateway is a managed service that allows developers to define the HTTP endpoints of a REST API or a WebSocket API and connect those endpoints with the corresponding backend business logic. It also handles authentication, access control, monitoring, and tracing of API requests.

How does API Gateway work?

API Gateway sits between the backend services of your API and your API’s users, handling the HTTP requests to your API endpoints and routing them to the correct backends. It provides a set of tools that help you manage your API definitions and the mappings between endpoints and their respective backend services.

Amazon API Gateway is a fully managed service that makes it easy for developers to create, publish, maintain, monitor, and secure APIs at any scale. APIs act as the “front door” for applications to access data, business logic, or functionality from your backend services. Using API Gateway, you can create RESTful APIs and WebSocket APIs that enable real-time two-way communication applications. API Gateway supports containerized and serverless workloads, as well as web applications.
