Editor's Notes
- #2 “IoT Suite is an enterprise grade solution that allows you to get started quickly through a set of extensible pre-configured solutions for common IoT scenarios
- #3 The growth in IoT will far exceed that of other connected devices.
- #6 Azure IoT Suite • Collect data from devices • Analyse data streams in-motion • Store and query large data sets • Visualize both real-time and historical data • Integrate with back-office systems Azure IoT Suite packages together Azure IoT services with preconfigured solutions. These preconfigured solutions
- #7 Remote Monitoring • Connect and monitor your devices • Analyze untapped data • Improve business outcomes by automating processes Predictive Maintenance • Anticipate maintenance needs • Avoid unscheduled downtime by connecting and monitoring your device
- #8 Field gateway A field gateway is a specialized device-appliance or general-purpose software that acts as a communication enabler and, potentially, as a local device control system and device data processing hub. A field gateway can perform local processing and control functions toward the devices; on the other side it can filter or aggregate the device telemetry and thus reduce the amount of data being transferred to the cloud backend. Cloud gateway A cloud gateway is the part of the cloud-based architecture that enables remote communication to and from devices or field gateways, which potentially reside at several different sites. A cloud gateway will either be reachable over the public Internet, or a network virtualization overlay (VPN), or private network connections into Azure datacenters, to insulate the cloud gateway and all of its attached devices or field gateways from another network traffic. 3.1 Devices, Device Connectivity, Field Gateway (Edge Device), Cloud Gateway Devices can be connected directly or indirectly via a field gateway (IoT edge device). Both devices and field gateways may implement edge intelligence including analytics capabilities. This enables aggregation and reduction of raw telemetry data before transport to the backend, and local decision-making capability on the edge. Following is a conceptual representation of the different device connectivity options for IoT solutions. The numbers in the figure correspond to four key connectivity patterns, defined as follows: Direct device connectivity to the cloud gateway: For IP capable devices that can establish secure connections via the Internet. 2. Connectivity via a field gateway (IoT Edge Device): For devices using industry specific protocols (such as CoAP5, OPC), short-range communication technologies (such as Bluetooth, ZigBee), as well as for resource-constrained devices not capable of hosting a TLS/SSL stack, or devices not exposed to the Internet. This option is also useful when aggregation of streams and data is executed on a field gateway before transferring to the cloud. 3. Connectivity via a custom cloud gateway: For devices that require protocol translation or some form of custom processing before reaching the cloud gateway communication endpoint. 4. Connectivity via a field gateway and a custom cloud gateway: Similar to the previous pattern, field gateway scenarios might require some protocol adaption or customizations on the cloud side and therefore can choose to connect to a custom gateway running in the cloud. Some scenarios require integration of field and cloud gateways using isolated network tunnels, either using VPN technology or using an application-level relay service.
- #11 IoT Hub Azure IoT Hub is a fully managed service that enables reliable and secure bidirectional communications between millions of IoT devices and a solution back end. Azure IoT Hub: • Provides reliable device-to-cloud and cloud-to-device messaging at scale. • Enables secure communications using per-device security credentials and access control. • Provides extensive monitoring for device connectivity and device identity management events. • Includes device libraries for the most popular languages and platforms
- #14 Azure IoT Hub. Azure IoT Hub is a high-scale service enabling secure bidirectional communication from a variety of devices. Azure IoT Hub connects millions of devices and supports high-volume telemetry ingestion to a cloud backend as well as command and control traffic to devices. Azure IoT Hub supports multiple consumers for cloud ingestion as well as the inbox pattern for devices. Azure IoT Hub provides support for the AMQP 1.0 with optional WebSocket6 support, MQTT 3.1.17, and native HTTP 1.1 over TLS protocols. Azure Event Hubs. Azure Event Hubs is a high-scale ingestion-only service for collecting telemetry data from concurrent sources at very high throughput rates. Event Hubs could also be used in IoT scenarios, in addition to IoT Hub, for secondary telemetry streams (that is, non-device telemetry), or collecting data from other system sources (such as weather feeds or social streams). Event Hubs doesn’t offer per-device identity or command and control capabilities, so it might be suited only for additional data streams that could be correlated with device telemetry on the backend, but not as a primary gateway for connecting devices. Azure Event Hubs provides support for the AMQP 1.0 with optional WebSocket support, and native HTTPS protocols
- #28 The preconfigured solutions typically use the following services: • Azure IoT Hub service (the core) • Provides the device-to-cloud and cloud-to-device messaging capabilities and acts as the gateway to the cloud and the other key IoT Suite services. The service enables you to receive messages from your devices at scale, and send commands to your devices. • •Azure Stream Analytics • provides in-motion data analysis. IoT Suite leverages this service to process incoming telemetry, perform aggregation, and detect events. The preconfigured solutions also use stream analytics to process informational messages that contain data such as metadata or command responses from devices. The solutions use Stream Analytics to process the messages from your devices and deliver those messages to other services. • Azure Storage and Azure DocumentDB • Provide the data storage capabilities. The preconfigured solutions use blob storage to store telemetry and to make it available for analysis. The solutions use DocumentDB to store device metadata and enable the device management capabilities of the solutions. • Azure Web Apps and Microsoft Power BI • Provide the data visualization capabilities. The flexibility of Power BI enables you to quickly build your own interactive dashboards that use IoT Suite data
