What machine is actually processing the data?

[christianunr]

Our setup in my department uses the on-premises gateway that is setup on a Windows Server machine. 

Is the Windows Machine that has the gateway doing the actually data processing or is it being sent to a VM hosted on Azure?

I've never understood what machine is actually being used to process the data/applied steps/etc. when a refresh is taking place.

Hi @christianunr 

Yes, your windows machine connects to your local data sources, completes all the power query steps, processes the data, and then sends it through to the power BI service.
