What is API Gateway

API Gateway acts as a "front door" for applications to access data, business logic, or functionality from your backend services, such as workloads running on Amazon Elastic Compute Cloud (Amazon EC2), code running on AWS Lambda, any web application, or real-time communication applications.


1. Use API Gateway to Create HTTP APIs

HTTP APIs enable you to create RESTful APIs with lower latency and lower cost than REST APIs.You can use HTTP APIs to send requests to AWS Lambda functions or to any publicly routable HTTP endpoint.

For example, you can create an HTTP API that integrates with a Lambda function on the backend. When a client calls your API, API Gateway sends the request to the Lambda function and returns the function's response to the client

2. Use API Gateway to Create REST APIs

An API Gateway REST API is made up of resources and methods. A resource is a logical entity that an app can access through a resource path.A method corresponds to a REST API request that is submitted by the user of your API and the response returned to the user

3. Use API Gateway to Create WebSocket APIs

In a WebSocket API, the client and the server can both send messages to each other at any time. Backend servers can easily push data to connected users and devices, avoiding the need to implement complex polling mechanisms
