I am trying to understand Amazon AWS IoT and I see there is a Device Gateway connected between Sensors/Actuators and AWS (Rules Engine). I understand Sensors/Actuators are MQTT Clients which can Publish/Subscribe to the topics.
Device Gateway also supports Publish/Subscribe pattern is that means
Device Gateway is also a MQTT Client ?
Then where is the MQTT broker?
OR Device Gateway is Broker + communication interface to AWS-IoTservices?
I have attached an Image Amazon presentation on AWS IoT for the reference:

AWS IoT Core supports device connections that use the MQTT protocol and MQTT over WSS protocol and that are identified by a client ID. The AWS IoT Device SDKs support both protocols and are the recommended ways to connect devices to AWS IoT.
This implementation enables write-only messages to be published on given MQTT topics, and also supports shadow updates of HTTPS devices to allowed things in the device registry.
Included in AWS IoT Core is a Device Gateway that allows secure, low-latency, low-overhead, bi-directional communication between connected devices and your cloud and mobile applications. AWS IoT Core also contains a Rules Engine which enables continuous processing of data sent by connected devices.
AWS IoT Core Now Supports MQTT Connections with Certificate Based Client Authentication On Port 443. Beginning today, you have more options to securely connect your devices to AWS IoT Core. You can use MQTT with certificate based client authentication on port 443.
The gateway is a MQTT broker, but not a fully compliant one. Some of the differences are:
