Each software usually provides a number of configuration parameters which can
be set before instantiating a service (creating an instance). After the service
has been instantiated, all parameters are accessible and editable on the service
page of the NMS Dashboard.
Note, that updating an instance (for example by changing a parameter),
will only update this specific instance. All other instances of the same service
remain unchanged. In order to update all instances of a service (for example adding
a new parameter), it is required to create a new software release and trigger the
update of all instances to change to this new release.
