Description

Amazon API Gateway is a fully-managed service aimed at developers who want to create rich and complex APIs in the public AWS cloud. It makes it easy to create, manage, monitor, secure, and scale your API-backed applications. WebSockets are a technology that makes it easy to send and receive data in a bi-directional manner between a server and a web browser.

Learning how to use Amazon API Gateway for WebSockets will make you more effective and versatile when deploying applications with complex needs in the cloud.
