React to Critical Device Lifecycle Events and Trigger Actions

Header Image

Azure IoT Hub integrates with Azure Event Grid so that you can send event notifications to other services and trigger downstream processes. Configure your business applications to listen for IoT Hub events so that you can react to critical events in a reliable, scalable, and secure manner. For example, build an application to perform multiple actions like updating a database, creating a ticket, and delivering an email notification every time a new IoT device is registered to your IoT hub.
