1. A method comprising: receiving by an apparatus, via a wide area network, a request for deployment of a selected one of available virtualized network services advertised by the apparatus via the wide area network, the request identifying a host service provider to deploy the one virtualized network service; identifying, by the apparatus, virtualized network functions required by the host service provider for implementation of the one virtualized network service, each virtualized network function having a corresponding and distinct virtualized container specifying attributes for defining execution of the corresponding virtualized network function within one or more physical machines of the host service provider, the one virtualized network service and each virtualized network function distinct from any cloud service executed under control of a cloud orchestrator in the host service provider; and sending to a network orchestrator of the host service provider, via the wide area network, by the apparatus, a service container specifying instructions for the network orchestrator deploying the one virtualized network service among the physical machines having respective virtualization domains with respective distinct administrative controls, the network orchestrator distinct from the cloud orchestrator and the service container including instructions for causing the network orchestrator to deploy the virtualized network functions among the physical machines and as interdependent for implementation of the one virtualized network service by the host service provider.
