What is an IAM system, and what are IAM architecture and IAM policy?

An IAM system is an implementation of IAM within a defined scope, used by an organisation, comprising technical entities such as IdPs and RPs, the people involved such as subjects and IAM owners, and the underlying processes such as registration and user administration; the IAM architecture consists of the concepts, processes and topologies and their relationships within it; the IAM policy defines its goals, principles and system boundaries.

Synonym for IAM system: identity system.
