Platform Engineering

I'm struggling on the definition of an IDP and the location of it. The cloud providers provide an very consistent experience for developers in terms of self-service, APIs etc.
Do many organizations use f.e. Azure or AWS as their IDP, or is an IDP always running in the premise of the organization?
