The DSK IoT Hub Bridge is the part that connects the DSK Node to the Azure IoT Hub. The IoT Hub is used for device-management and communication. The IoT Hub is also used to deploy the Edge Agent onto an Edge Device. The Edge Agent receives data from one or more data-sources and forwards it to the IoT Hub. The DSK IoT Hub Bridge forwards the data to the DSK Node.
In Azure the IoT Hub Bridge can easily be set up using an ARM Template. This template deploys a new instance of the Azure IoT Hub in combination with the DSK IoT Hub Bridge. The required steps are described in the quick-start-guide.
