AWS API Gateway Overview

https://www.serverless.com/amazon-api-gateway

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. It also handles authentication, access control, monitoring, and tracing of API requests.

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

It provides a set of tools that help you manage your API definitions and the mappings between endpoints and their respective backend services. It can also generate API references from your definitions and make them available to your users as API documentation.

How does API Gateway integrate with other AWS services?

API Gateway integrates with many other AWS services like AWS Lambda, AWS SNS, AWS IAM, and Cognito Identity Pools. These integrations allow for fully managed authentication and authorization layers, as well as detailed metrics and tracing for API requests.
