Organizations rely on Azure IoT Hub to securely connect, manage, and route data from millions of devices. As operational data volumes continue to grow, customers are looking for simpler ways to bring device telemetry into analytics, AI, and digital operations solutions without building and maintaining custom integration pipelines. Today we're excited to announce the Public Preview of Microsoft Fabric Eventstreams as a native IoT Hub routing endpoint. Microsoft Fabric provides a unified platform for real-time analytics. By bringing enriched IoT data directly into Fabric, organizations can accelerate the path from data ingestion to insight and action within a managed environment.

Getting started with Microsoft Fabric Eventstreams

Fabric Eventstreams is a service within Microsoft Fabric Real-Time Intelligence that ingests events from multiple sources, transforms them using no-code, low-code event processors, and routes data to various destinations. The platform provides source connectors for multiple event types, optional transformation capabilities, and support for Kafka endpoints, enabling teams to capture and route real-time signals across databases and external data sources. Learn more about Fabric Eventstreams.

Leverage IoT Hub’s routing and enrichment capabilities to land operational data in Microsoft Fabric

The addition of Fabric Eventstreams as an Azure IoT Hub routing endpoint enables organizations to create new or extend existing IoT Hub message routes. Customers can continue using routing rules, filters, and message enrichments configurable in Azure IoT Hub, now with Fabric Eventstreams as a supported destination.

Once data is routed into Fabric, customers can analyze streaming telemetry in real time, filter, transform, or combine device data with business and operational datasets, detect patterns across assets and environments, and trigger actions based on changing conditions. Additionally, customers can route this data to other Fabric destinations like Eventhouse, Lakehouse, etc., set up alerts, and build real-time dashboards.

Preserving operational context with CloudEvents

CloudEvents is an industry-standard envelope, preserved across transports and encodings, that separates event metadata from the event payload. Events routed from Azure IoT Hub to Microsoft Fabric Eventstreams are delivered using the CloudEvents schema, enabling a consistent event format across IoT Hub message types. Learn more about how the schema is structured.

Through the CloudEvents envelope, device identifiers, event timestamps, message identifiers, routing metadata, and IoT Hub enrichments are persisted alongside the payload. Additionally, for customers using Azure IoT Hub instances with Azure Device Registry enabled, the externalID field is carried forward in the payload, helping maintain the connection between telemetry and assets for downstream analytics workflows.

Preserving critical context helps downstream systems understand and act on operational data by retaining the information needed to identify what an event is, where it came from, and what should happen next.
