Azure IoT Hub
Connect, monitor, and manage billions of IoT assets.
Overview
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.
- 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.
- Device Update for IoT Hub is a comprehensive platform that customers can use to publish, distribute, and manage over-the-air updates for everything from tiny sensors to gateway-level devices. Explore the benefits of implementing Device Update for IoT Hub, which include being able to rapidly respond to security threats as well as deploy features to meet business objectives without incurring the additional development and maintenance costs of building your own update platforms.
- 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.
- Register and provision devices with zero touches, in a highly secure and scalable way. The IoT Hub device provisioning service supports any type of IoT device compatible with IoT Hub.
- Easily create and deploy IoT Edge modules to transmit code and services between the cloud and the edge. Distribute intelligence—including AI and other advanced analytics—across a range of devices, all while reducing your IoT application costs, easing development efforts, and running devices offline or with intermittent connectivity.

Frequently asked questions
- 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.
