API Gateway is a fully managed service by Amazon that can be used to create secure REST and WebSocket APIs. Using API Gateway, developers can easily create and manage their APIs at any scale.
An API is a way to distribute business logic in a set of clearly defined methods. APIs simplify communication between two or more application components and enable the developers to achieve greater functionality. API Gateway can accept and process thousands of concurrent API calls. API Gateway can authorize users, handle traffic, and can also monitor the performance of the APIs.
