Your task is to plan, how would you implement IoT-management and monitoring system. The overall architecture and used technologies. Just main ideas, not detailed architecture or implementation details. System needs to run on azure. IoT-devices communicate using Azure IoT Hub. IoT-sensors are configured through Device Twins. Data is sent from IoT-sensors as standards IoT Hub telemetry messages once every 20s. Same system will be used by multiple end-customers, so the access needs to be limited to data of their own devices.
