An example of IoT Solution 9/11/2018 1:44 PM An example of IoT Solution Devices Azure IoT Suite Remote Monitoring Back end systems and processes Web/ Mobile App Storage blobs DocumentDB How does it work? As mentioned; the solution is a combination of multiple back-end components. This architecture diagram shows the individual Microsoft products and services that are utilized. Reference Architecture for Remote Monitoring solution, what products are used and why? -> Provision simulated devices with a C# device emulator running .Net. Create agents for Linux, iOS, Android and other platforms with C and Java language support. IoT Hub manages the two way communication between cloud and device and creates a secure command and control channel. Azure Stream Analytics creates and manages jobs to recognize threshold values or detect alarm triggers, sending this information where it needs to be escalated. Event Hub is queried by a web job running an event processor host to determine where and alarm or alert needs to be pushed – such as sending an alert to dashboard for a human operator to take action. Logic Apps are used to create more complex work loads and integrate into line of business and other proprietary applications. Document DB stores all the metadata and device properties for each connected device. Blobs store telemetry information and telemetry data. Other tools such as Azure Machine Learning and PowerBI can access this information for data visualization or processing advanced analytics. Webapp – Dashboard code is available in Github allowing it to be fully customized by the user to align with a scenario or be relevant for an enterprise application. Azure Active Directory controls user ID’s and access, allowing the service to be shared with relevant decision makers within the business but restrict access to certain controls or devices. PowerBI is used for both open-source embedded components within the dashboard and also for complex external analytics of trends and patterns across all stored data.

IoT Hub endpoints IoT Hub Build 2015 9/11/2018 1:44 PM Event Hub, Service Bus Topics, Service Bus Queues, Others... (hot and cold path) IoT Hub D2C custom endpoints Device Device id D2C send endpoint Event processing (hot and cold path) D2C receive endpoint C2D queue endpoint Device management, device business logic, Connectivity monitoring Twin endpoint C2D send endpoint Methods endpoint Msg feedback and monitoring endpoint Gateway IoT Hub exposes a set of conceptual endpoints to access its functionalities. There are two endpoints for each device: one to send D2C msgs, one to receive C2D msgs. Devices can connect two both endpoints over the same connection. FGW and CGW are able to represent multiple devices by simultaneously connecting to D2C and C2D endpoints for many devices at the same time. On the app back-end side, the D2C receive endpoint is used by the event processing pipeline (ASA, Storm, custom, …), and by the device runtime logic component, which handles requests and command responses that come from devices. The device runtime logic component also uses the C2D send endpoint to send notifications and commands to devices. It also uses the msg feedback and monitoring endpoint. This is critical for IoT solutions where devices are reachable only through IoT Hub. In these very common scenarios, any problem on the connectivity between device and IoT Hub cannot just be reported as errors back to the device, but also to the app back-end in the form of events on this feedback endpoint. This makes possible the kind of monitoring that is required to achieve high operability of an IoT solution. In addition to these runtime endpoint, IoT Hub also has a device identity mgmt endpoint that is used by your solution’s device provisioning and mgmt component. Finally, an IoT Hub Manage endpoint is used to set security, functional, performance parameters.
