Contrasting Data Warehouses with Power BI Dataflows

Reza Rad makes a comparison:

Dataflow is the data transformation service in Power BI, and also some other Power Platform services. Data Warehouse is the cloud storage and also compute engine for data. I often get this question that: “Now that we have dataflow in Power BI, should we not use the Data warehouse? What are the differences? which is better? When to use what?” This article and video, explains answer to these questions.

I’m probably a bit lower on self-service BI compared to others. When I see something like Dataflows, it reminds me too much of a mess of Excel spreadsheets on shared drives. There’s a lot of relevant business knowledge embedded in those disbursed locations, and bringing it together becomes as much a forensic exercise as it is architectural.
