An NFV Orchestrator coordinates the lifecycle of the multiple VNFs that together realize a network service, including their associations, topology, and service-level lifecycle operations. VNF-specific lifecycle management is performed by the VNF Manager, and NFVI compute, storage, and network resource management is performed by the Virtualized Infrastructure Manager.
