AWS API Gateway Overview

What is Amazon API Gateway?

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.

(So basically it condenses backend work and simplifies the process of a backend.)

Why is Amazon API Gateway an important part of the Serverless ecosystem?

Having the ability to execute a serverless function directly in response to an HTTP request is the selling point of API Gateway

How does API Gateway integrate with other AWS services?

AWS Lambda: run Lambda functions to generate HTTP API responses.

AWS SNS: publish SNS notifications when an HTTP API endpoint is accessed.

Amazon Cognito: provide authentication and authorization for your HTTP APIs.
