The NFVI operator is the CSP. The CSP is responsible for creating the NVF environment as well as for its operation.

In a typical NFV environment, VNF vendors do not have access to the infrastructure management components such as NSX-T Manager or vCenter Server. The CSP cloud administrator creates logical resource entities for each tenant. In the deployment model that NFV customers often use, a tenant is the construct where a VNF is placed. All interactions between the virtual infrastructure and the VNF are performed through the available cloud management interfaces from within the VNF tenancy. It is therefore the responsibility of the CSP to ensure that all host-level configurations are prepared for data plane intensive workloads. The CSP configures the hardware and software and assigns the appropriate resources to the virtual networking. These resources are then consumed by the VNFs as needed.
