How should you tackle SDN? Look to WAN

The rapidly changing Software Defined Networking (SDN) movement is arguably the best indicator of the disruptive forces occurring now in infrastructure innovation.

However, until recently, much of the focus on SDN has centered on the data center. But that may not necessarily be best, according to Michael Elmore, IT Senior Director of the Enterprise Network Engineering Infrastructure Group at Cigna. Elmore, who also serves on the board of the Open Network Users Group, argues in a recent interview with Network World, that the wide area network (WAN) could be a better use case for handling SDN:

Consider this quote from a Wall Street firm at the recent Open Networking User Group meeting in New York: “Although much of Wall Street has focused on the ‘sexy’ datacenter aspect of SDN, interest in software-defined WAN has increased meaningfully and we believe SD-WAN could experience more rapid adoption than datacenter overlay technologies. SD-WAN can dramatically reduce the cost of WAN deployments by enabling cheaper bit rates in both CAPEX and OPEX (i.e., less cost for the same bandwidth or more bandwidth for the same cost as compared to MPLS) and less over-provisioning for the same SLAs.”

What’s more, the WAN tends to be more discreet in terms of organizational teams and the technology stack itself, meaning organizations can move faster to embrace SD-WANs. So, if you’re interested in building a WAN that is better, faster and cheaper, there are some key issues to consider.

Elmore’s interview provides valuable insight into the value WAN can offer to companies. More importantly, he proves that as mission-critical business applications, like voice and storage, increasingly move to the cloud, a “high-performing” IP WAN is critical to business.

Still, challenges exist. CIOs around the world may see value in the WAN solution, but have trouble navigating the myriad solutions and justifying the associated costs. In far too many cases, CIOs still don’t have the right resources to find the ideal WAN solution.

Each day, Subsidium Technologies sees such issues in the C-suite and actively works with CIOs to mitigate the costs and find the right solutions for their unique businesses. Elmore’s argument that WAN is a crucial component in SDN is increasingly apparent in today’s IT environment and illustrates why the Subsidium team works so hard for its partners to identify the right solutions, at the right price, to maximize productivity and business gains.
