3. The Transformation of Networking
Enable networking to drive business innovation & agility
Platforms enable orgs to simply & powerfully control
cloud orchestrated compute functions
Platform enables orgs to simply & powerfully control
cloud orchestrated networking functions

4. Agile and secure – fundamentals of digital business – are impossible to achieve
with a traditional network designed for business as usual.
A new approach to their network is needed that distributes network capability to
wherever apps need them, independent of underlying infrastructure
