 ### Edge MQTT broker integration
-Event Grid integrates with [Azure IoT MQ](https://aka.ms/iot-mq) to bridge its MQTT broker capability on the edge with Azure Event Grid’s MQTT broker feature in the cloud.  Azure IoT MQ is a new distributed MQTT broker for edge computing, running on Arc enabled Kubernetes clusters. It can connect to Event Grid MQTT broker with Microsoft Entra ID (formerly Azure Active Directory) authentication using system-assigned managed identity, which simplifies credential management. Azure IoT MQ provides high availability, scalability, and security for your IoT devices and applications. It's now available in [public preview](https://aka.ms/iot-mq-preview) as part of Azure IoT Operations. [Learn more about connecting Azure IoT MQ to Azure Event Grid's MQTT broker](https://aka.ms/iot-mq-eg-bridge).
