Orchestration has become an overloaded word in the industry. While Network Orchestration and Application Orchestration share a lot of technologies coming from the domains of SDN and NFV, the 2 approaches serve different objectives. The paper will specifically address Network Orchestration, aiming at launching new revenue generating Business Connectivity services rapidly, with Value Added services running in private or public cloud data centers chained-in into the Network Service. The rapid market traction of SD-WAN overlay IP networking, enabled by product suites such as Nuage, fuels the requirements for Network Orchestration: overlay to underlay connectivity, connectivity into Public Cloud, Internet Break-out, flexible onboarding of virtualized Value Added services such as firewalls, wan optimizers, email filters, and others, all easily customizable for that one specific enterprise customer of the MSO.
