Explanation
Box 1: Azure IoT Central
Microsoft Azure IoT Central enables builders to configure rules and actions. Based on those actions, IoT alerts will be created in Connected Customer Service. Also, based on service activities in Connected Customer Service, information can be sent back to IoT Central. This is accomplished by using Power Automate, a SaaS offering for automating workflows across applications and services.
Box 2: Azure IoT Hub
Connected Customer Services uses the IoT Hub to manage the state of registered devices. In addition, the IoT Hub sends commands and notifications to connected devices-and tracks message delivery with acknowledgment receipts. Device messages are sent in a durable way to accommodate intermittently connected devices.
