Azure IoT Hub
Managed service to enable bi-directional communication between IoT devices and Azure
Build your IoT application with two-way communication
Enable highly secure and reliable communication between your IoT application and the devices it manages. Azure IoT Hub provides a cloud-hosted solution backend 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 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.Read the documentation
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.Learn more about Azure security for IoT
Automate device provisioning to accelerate IoT deployment
Register and provision devices with zero touches, in a highly secure and scalable way. IoT Hub Device Provisioning Service supports any type of IoT device compatible with IoT Hub.Read about IoT Hub device provisioning
Extend the power of the cloud to your edge devices
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.Explore IoT Edge

Frequently asked questions about Azure IoT Hub
IoT Hub Basic is an ideal place to start your IoT deployment if you don’t need bi-directional communication but still with foundational IoT security with per-device authentication, highly scalable device support, and a seamless upgrade path to IoT Hub Standard. Standard enables device management and Azure IoT Edge support. Event Hub is designed for big data scenarios, such as website data ingestion. See a detailed comparison.
Azure IoT Hub and IoT Hub device SDKs support the following protocols for connecting devices.
- AMQP over WebSockets
- MQTT over WebSockets
If your application can’t use one of the supported protocols, extend IoT Hub to support custom protocols by doing the following.
