About Amazon API Gateway

Amazon API Gateway is a managed service from Amazon Web Services for building and operating APIs. Developers define REST and WebSocket APIs, connect them to backends such as Lambda functions or other AWS services, and let AWS handle the infrastructure that receives and routes requests.

The service covers publishing, securing and monitoring APIs, with features like authorization, throttling and request handling. API Gateway is a proprietary AWS service with no self-hosted edition, and it is billed on usage; AWS documents the current API types, limits and pricing.
