Orchestration and Management In the NFV architectural framework proposal, the traditional O&M (Operation & Management) sub-systems evolves to an Orchestration and Management Plane: Service awareness: a VNF Manager monitors the evolving requirements of the Network Functions network elements Substrate heterogeneity awareness: a Virtualised Infrastructure Manager (VIM) handles the heterogeneity of the underlying resources and monitor them Efficient embedding Orchestration Closed-loop/autonomic: monitoring subsystem integrated in the SDN orchestration framework Slide 3 Riccardo Guerzoni NOMS 2014 Distinguished Experts Panel Service awareness Efficient Embedding Substrate heterogeneity awareness (Closed loop) From Network Functions virtualization (NFV); architectural framework, 2013.

Orchestration of virtually endless clouds One fundamental objection against centralized orchestration is scalability. Actually the Orchestrator does not need to be omniscient. In federated environments, cloud resources and services can be described, discovered and requested at abstract level, by means of to- s.
