API Gateways

An API Gateway makes it easy for developers to deploy APIs, and makes it possible for clients to access, APIs over the Internet. APIs provide an “end point” for applications to access data, business logic, or functionality from your backend services. The endpoints are accessible by clients via the API Gateway.

API Gateways handle all the tasks involved in accepting and processing API calls, including traffic management, CORS (cross-domain) support, authorization and access control, throttling, monitoring, and version management.
