The IoT hub is analogous to the IoT middleware that we looked at in Chapter 1, Introduction to IoT. The IoT hub helps us to connect, monitor, and manage billions of IoT assets.
Some of the key features are as follows:
- Authentication per device
- Extended and comprehensive device management
- Communication with billions of IoT devices
- Device registration and provisioning
- Support of MQTT(S), AMQP, and HTTPS protocols for device-to-cloud communication
