DESCRIPTION
While much has been said about network virtualization, current solutions remain limited to simplistic use cases, restricting services within boundaries of single data centers or virtualized islands. We describe a novel approach that fulfills the promise of massively scalable network virtualization and enables the seamless interconnection of cloud services with existing enterprise environments.

…but delivering a technology is only part of the solution
We need to drive a cultural change…
Let’s start with changing the organization
When all you have is a hammer… And shift our operational methods
Trouble Tickets, Manual Processes
Continuous network service delivery DevOps for NetOps
Application driven automation
Provide a complete toolkit…
Help us (netops) get there
• Don’t accept the status quo
• Empower your netops team to improve the service they deliver to you
• Include your network architects early in technology research
• Encourage a “blurry” demarcation of responsibilities • Encourage your network engineers to take a codecademy course
