|Using Power BI in a Hybrid Environment||
Many organizations are taking advantage of the benefits of cloud computing such as lower capital expenditures and increased agility, while still maintaining data in on-premises data stores.

Applies to: SQL Server, Microsoft Power BI, Microsoft Azure

Of course, I'm especially proud of this whitepaper, because it was identified as a big content gap by our Power BI customers, I project-managed it with the help of Carla Sabotta, and we got some of our brightest SQL Server MVPs to author it (Joey D'Antoni and Stacia Misner).
And special thanks to all our reviewers! They are listed at the top and with more info at the bottom of the whitepaper.
