AWS IoT is Amazon's implementation of an IoT gateway.

AWS IoT is a managed cloud platform that lets connected devices easily and securely interact with cloud applications and other devices. It works as a gateway for your devices (things) to communicate with any of the AWS services. AWS IoT can support billions of devices and trillions of messages, and can process and route those messages to AWS endpoints and to other devices reliably and securely.
