The document discusses the potential of network virtualization to address challenges posed by the growth in dynamic virtualized workloads. It notes traditional networks are configuration-driven, complex and inflexible, limiting optimization. Network virtualization provides a programmable, automated approach through software-defined networking, delivering instant, policy-based connectivity across datacenters seamlessly without network constraints. This represents a fundamental shift from static configuration to dynamic service automation through abstraction of the network.

23. …but delivering a technology is only part of the solution
We need to drive a cultural change…

24. Let’s start with changing the organization

25. And shift our operational methods
Trouble Tickets, Manual
Processes
When all you have is a hammer…

26. Provide a complete toolkit…
Continuous network service delivery
DevOps for NetOps
Application driven
automation

27. 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
