sending, by a network functions virtualization orchestrator (NFVO) to a virtualized network function (VNF) manager (VNFM), a VNF instantiation request message requesting to instantiate a VNF to start a VNF instance for an application for a network service (NS), wherein the application is not combined with another application into the NS and is not split into functional components or services;
