1. A method comprising:
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;
obtaining, by the VNFM based on a quality of service (QoS) attribute of the VNF and a preset mapping relationship between the QoS attribute and a virtual resource location area, the virtual resource allocation area as a target virtual resource location area for deploying the VNF instance;
sending, by the VNFM to a virtualized infrastructure manager (VIM), a virtual resource allocation request message requesting to allocate a virtual resource for deploying the VNF instance, wherein the virtual resource allocation request message carries first information about the target virtual resource location area;
sending, by the VIM to the VNFM, a virtual resource allocation response message indicating second information about a target virtual resource for deploying the VNF instance, wherein the target virtual resource is located in the target virtual resource location area; and
instantiating, by the VNFM and based on the second information, the VNF on the target virtual resource.
