Do cloud plateforms fall under BPMN frameworks/plateforms? From what I understand, it's possible to build applications today using cloud plateforms (AWS and Azure mostly, I don't know about the others) for auth, persistance, etc; while only writing your business logic, especially now with serverless where you only write functions.

In a way this is the return of the distinction between application and system, but the system is left to another company. This would fit with the (anecdotal) pattern I've noticed where before companies had cleaning people, IT people, etc and now everything is subcontracted to other companies.
