Overview
A data gateway in Microsoft Fabric and Power BI is the secure connectivity layer that allows cloud services to access data sources that aren’t publicly reachable. This includes on-premises systems, Azure resources locked behind private endpoints, and streaming platforms running inside private networks.
Gateways are critical because most real-world architectures are hybrid. Even as organizations adopt Fabric, they often need to integrate with legacy systems, tightly secured Azure services, or real-time platforms that cannot be exposed to the public internet. Gateways make this possible without compromising security or network boundaries.
Microsoft Fabric currently supports three gateway types, each optimized for a different scenario:
- On-premises data gateway
- Virtual network data gateway
- Streaming virtual network data gateway
Understanding when to use each one helps avoid unnecessary complexity and ensures the right balance of security, performance, and manageability.
