Azure IoT Hub is a scalable, multi-tenant cloud platform (IoT PaaS) that includes an IoT device registry, data storage, and security. It also provides a service interface to support IoT application development. Azure IoT helps you to securely connect millions of Linux, iOS, Android, Windows, and real-time operating system (RTOS) devices to reliably send telemetry and receive commands from application back-end in the cloud IoT Hub helps connect your devices to Azure Millions of simultaneously connected devices Per-device authentication High throughput D2C messaging Reliable C2D messaging Overview of Azure IoT Hub Internet Protocol capable devices can be connected directly to IoT Hub. Private Area Network devices (devices connected through Bluetooth, NFC, RFID, Zeegbee, Home automation through PLC) are connected through Field gateway to IoT Hub / Cloud protocol gateway.
