34 Summary And Discussion Points SDN/NFV is a strategic technology transformation Its not about virtualizing a VNF on a bunch of servers Its about hosting VNFs on a Open, Programmable, Intelligent Network Infrastructure with flexibility to Manage and Automate Services Raising key questions: How does SDN/NFV add to economic and strategic value to your business? How much of automation of Physical & Virtual services has been achieved? Leading to high Operational disruption How do you plan to manage the complex cost of transition effectively? Process Tools People What's the value you plan to derive out of Open source tools? 2017 Cisco and/or its affiliates. All rights reserved. Cisco Public
