So here's my exprience:
We have data on prem, and in cloud. No problem understanding that.
This tool is also about data. Big data. Lots of data. So it's automatically going to be about thousands of datasets and millions of rows. That's called "Normal" in this business.
So why is it so difficult to make this bucket of bolts just work with that?
Get data from on prem needs gateways. Gateways don't work unless third party products are developed to solve authentication problems between Office365 and Windows Domains. I thought they were both Microsoft? Maybe I missed something,
The advice from the technical experts is "just publish your data to the cloud". Every time you want to refresh your report. It's less than 100,000 rows right now, but as we get into the groove (assuming we can), it's going to be millions. Who on earth thinks that rebuilidng the data warehouse everytime I want to refresh a report is a clever way of doing things?
Get data from SharePoint: Can't be done.
Get data from Access: Need special drivers
Get data from gateway: The gateway has been dismanteled because it wasn't used in the last week.
To even get into Power BI Desktop needs me to sign in every time I use it. Not even my browser asks for that.
Get data is glossy slick advert with very little substance.
