== Configure ==

Note over MC,IC
In this step the VI frameworks is expected to be populated.
Normally the configuration would provide back the "definition" to enable a GUI
since we don't have a GUI the sOP has a predefined configuration instance.
end note

sOP -> IC : PUT ../serviceConfig/V1/serviceConfigurations/{serviceConfigLabel} {serviceInstanceConfig}

note left of IC
The Service Config is a container for resource configurations. As such there
Is nothing to modify therefore PUT is used for create since the user defines
The label. However there is no update allowed.
