Service Modeling Example 5 - Unmanaged Relationships Policy

This scenario, Add Hosted Systems, involves a system administrator whose company's IT infrastructure includes a domain manager that publishes information about operating systems. The operating systems are Linux-based operating systems. They are either hosting operating systems (which implies they run a virtual computer or computers) or hosted operating systems (which implies they run on a virtual system). The domain manager also publishes IsHostFor relationship between hosting and hosted operating systems. The system administrator wants to create an unmanaged relationship policy. The policy ensures adding a hosting operating system to a service also adds all hosted operating systems.

The system administrator creates a new unmanaged relationship policy using the Service Discovery Policy Editor wizard:
