Could SDN network virtualization change everything?

In the final part of his three-part presentation on software-defined networking (SDN) and network virtualization, expert Jim Metzler shares advanced details on virtualization and software-defined networks. He says there is a significant need for network virtualization. Network overlays represent a traditional approach to solving network problems, he explains, while SDN has potential to fundamentally change how networking is implemented.

He compares the methods in great depth and cites pros and cons for each means of implementation. 

Metzler also explores SDN in the WAN and discusses the advantages of bringing SDN into the data center and ongoing efforts.

He looks into SDN controller functionality and dissects specific areas such as scalability, performance and security. 

The main goals of SDN-based network virtualization include the ability to create flexible networks to meet diverse requirements and ensure isolation between virtual networks. And although admirable and feasible somewhere down the road, Metzler says SDN is still in the early adopter stage.

This presentation was recorded in January 2013.

Traditional on premise infrastructures look like they're coming to an end for most organizations. As hardware, monitoring and servicing maintenance are being cut left and right to save money the alternative is to outsource the infrastructure. The future is being aimed at the Application industry, in the name of progress things are going to change. Look back at SOA's of the the late 90's until now they really didn't work like they were intended. They needed a change in the way we compute they needed App environments, now that we are APP ORIENTED the next generation will develop into?X. Why not software-defined networking (SDN). Its all in the Configuration!
