How Power BI Gateway enhances your data connectivity and accessibility

The Power BI Gateway serves as a bridge, facilitating secure and efficient data transfer between the Power BI service and the data sources residing either on-premises or in other networks. The underlying principle of the Power BI Gateway is to augment the versatility of the Power BI ecosystem, enabling users to utilize their data, irrespective of where it resides. 

In this article, we’ll delve into the ways Power BI Gateway enhances your data connectivity and accessibility, making sure that data is always at the fingertips of those who need it.

What is Power BI Gateway?

Power BI Gateway is a bridge that facilitates secure data transfer between on-premises data sources and Microsoft Power BI cloud service. It acts as a relay, ensuring no direct connection between Power BI cloud service and on-premises data sources, enabling dataset refreshes and running cloud-based queries over on-premises data. 

Power BI offers two gateways: the On-premises data gateway and the Personal Mode. While the former is intended for enterprise-level usage and can be used by multiple users, the latter is designed explicitly for single-user scenarios.

Users install it on an on-premises machine to make the most of Power BI Gateway. Once installed and configured, the gateway ensures that Power BI cloud service can maintain scheduled refreshes or direct query data sources without storing your on-premises data source credentials in the cloud. It serves as the intermediary, ensuring all requests from the cloud are authenticated and directed appropriately to the on-premises data source.
