10. Remarks about Direct Query (with cloud sources)
Tiles are not refreshed in real-time
Each 15 minutes
Nothing to schedule
Direct Query … with a cache
Could be an issue on high velocity and low volumes
All data must come from the same data source
No calculated table
But measures (with limitations)!
Some calculated columns
Really limited query editor experience

11. Remarks about SSAS Live
Extremely cool, but is it really Power BI?
No creation of measures, columns, …
Not possible to use to the Query Editor
No remodeling
All data from a unique data source
Enterprise gateway

17. Key points and limitations
Difference between data and metadata
First « refresh » is special
Personal Gateway not needed if Power Query file is “cloud” based
Power Pivot behavior is similar to Power Query
Power BI v2 behavior is also similar

19. Why go through OneDrive?
Avoid usage of Personal Gateway
Usage of flat CSV files
Updates on OneDrive take less than 60 minutes to appear on Power BI.

21. Remarks about API Real-time refreshment! Limited Power BI experience
But only for tiles! (It’s perhaps smarter)

23. When do I need a « pro » version
More than 1Go of data
Scheduled refresh each hour (and not day)
Streaming via API larger than 10,000 rows/hour
Live connections
Gateway (Personal or Enterprise)
But also
Groups Office 365 ou AD
Content packs for organisations

24. Conclusion
Many similar architectures but each with notable differences
Test first … then implement
