17 EN RESUME NFV is truly on the move to production with major investments on all industry fronts moving focus to operations OpenStack is clearly the preferred VIM (Virtualized Infrastructure Manager) by most telco s worldwide Gaps in OpenStack for NFV are identified. Some will be addressed in future releases; some will depend on the ambition of OpenStack Nuage Networks SDN solution with its Neutron plug-in provide a scalable solution for networking Collaboration between vendors / telcos and open ecosystem are important to progress quickly OpenStack is definitively at the core of the NFV transformation 17
