Most developers in any way adjacent to Microsoft products have seen parts of Power Platform, or heard of Dynamics 365 or Dataverse, but the reuse of terminology and renaming of different components means many developers aren't aware of the breadth of ability and use cases with these products. From someone who took a job in a Dynamics 365 consulting firm without experience in these products, this is the crash course I wish I had received, to understand which pieces are designed for which purposes, and what kind of real use cases apply to different pieces of this ecosystem. This touches on the entirety of Microsoft Power Platform, Dynamics 365, and Dataverse.
