Microsoft Azure and cloud solutions
One of the first challenges when building an IoT solution is the connectivity between the cloud and the device. In some cases, devices are able to communicate to the cloud by themselves and sometimes devices will communicate via a field gateway. This is where the IoT Hub comes in. In the IoT hub, each connected device has its own d2c and c2d unique endpoint. Data from the various devices can be send to hot and cold paths, but also to device business logic. Some data in the messages will be device status, but also telemetry data can be used to analyse the status of a device.
