I recently got back from spending two days at the Open Networking User Group (ONUG) conference in New York. Kudos to Credit Suisse for hosting the event and to ONUG leadership for organizing it. It was exciting to meet forward-thinking IT leaders and hear about their need for an open networking standard.
Nick Lippis, co-chair of ONUG, brought this point home in his talk. One of his slides reported that more than 60 percent of organizations indicated that they needed at least one network engineer per 400 network devices. By contrast, one systems engineer can manage 10,000 VMs. Clearly, the network hasn’t kept up.
This was made particularly clear in ONUG’s work on the WAN. Software-Defined WAN (SD-WAN) is emerging as one of ONUG’s most pressing and concrete use-cases. The ONUG SD-WAN white paper is thought provoking and insightful, driven by marquee organizations, such as Bank of America, Gap, and FedEx.
Why do these IT leaders care so much about the WAN? Because they understand that if business is to continue to ride the benefits promised by virtualization, SDN and the cloud then there must be a solid foundation for those efforts. The WAN is that foundation, and business needs to be more:
By leveraging ubiquitous Internet links from multiple providers with an automated control plane, enterprises are able to realize all of those benefits. Costs decrease while availability, reliability and visibility increase.
ONUG’s work is playing an important role in the development of the SD-WAN. Check out the Top 10 Requirements of SD-WAN and see for yourself.
This post is part of an ongoing series examining the issues facing enterprises seeking to implement a Software-Defined WAN (SD-WAN) solution, as addressed in the Open Networking User Group white paper, “ONUG Software-Defined WAN Use Case”.
