When adding, removing, changing larger numbers of devices it is useful that upstream processes can be notified of such events.
For example adding or removing devices to Watson IoT may trigger actions in the asset management system to start the monitoring of devices, to add the device to the maintenance planning, etc.
Or adding a new device may trigger the automatic creation and configuration of (real time) analytics processes that analyze the data coming out of a sensor.
