The community has implemented manually triggered scale-out and scale-in
in combination with a specific VNF manager (sVNFM) and demonstrated this
with the VoLTE blueprint. An operator uses the Usecase UI (UUI) project
-to trigger a scaleing operation. UUI communicates with the Service
+to trigger a scaling operation. UUI communicates with the Service
Orchestrator (SO). SO uses the VF-C controller, which in turn instructs
a vendor-provided sVNFM to implement the scale-out action.
