Azure IoT Hub

Managed service for bidirectional communication between IoT devices and Azure

Build your IoT application with two-way communication

Enable highly secure and reliable communication between your Internet of Things (IoT) application and the devices it manages. Azure IoT Hub provides a cloud-hosted solution back end to connect virtually any device. Extend your solution from the cloud to the edge with per-device authentication, built-in device management, and scaled provisioning.

Security-enhanced communication channel for sending and receiving data from IoT devices

Built-in device management and provisioning to connect and manage IoT devices at scale

Full integration with Azure Event Grid and serverless compute, simplifying IoT application development

Compatibility with Azure IoT Edge for building hybrid IoT applications

Establish bidirectional communication with billions of IoT devices

Use device-to-cloud telemetry data to understand the state of your devices and define message routes to other Azure services—without writing any code. In cloud-to-device messages, reliably send commands and notifications to your connected devices and track message delivery with acknowledgement receipts. Automatically resend device messages as needed to accommodate intermittent connectivity.

Authenticate every device for enhanced security

Set up individual identities and credentials for each of your connected devices to help retain the confidentiality of both cloud-to-device and device-to-cloud messages. Selectively revoke access rights for specific devices as needed.

Frequently asked questions about Azure IoT Hub

  • IoT Hub Basic is an ideal place to start your IoT deployment if you don’t need bidirectional communication but still want foundational IoT security with per-device authentication, highly scalable device support, and a seamless upgrade path to IoT Hub Standard. The Standard tier enables device management and Azure IoT Edge support. Event Hubs is designed for big-data scenarios such as website data ingestion. See a detailed comparison.
  • Each Azure subscription has default quota limits, which could affect the scope of your IoT solution. The current limit is 50 IoT hubs per Azure subscription. To request quota increases, please contact support. Get more details.
  • Azure IoT Hub and IoT Hub device SDKs support the following protocols for connecting devices:

    • HTTPS
    • AMQP
    • AMQP over WebSockets
    • MQTT
    • MQTT over WebSockets

    If your application can’t use one of the supported protocols, extend IoT Hub to support custom protocols by:

    • Using IoT Edge to create a field gateway to perform protocol translation on the edge.
    • Customizing the Azure IoT protocol gateway to perform protocol translation in the cloud.
  • Azure IoT Hub provides a 99.9 percent service-level agreement.
