t cht lk “ WE BELIEVE THAT SD-WANS WILL CONTINUE TO COME INTO THEIR OWN DURING 2018, SHOWCASING THEIR REAL VALUE PROPOSITION IN A MULTI-FACTORED MANNER. Hughes believes that in 2018, most enterprises will start to adopt a ‘cloud-first’ SD-WAN architecture designed to efficiently and effectively support the ongoing evolution in their application mix. The new WAN edge will replace the traditional branch router With SD-WAN as a foundation, a new class of centrally-orchestrated, application-driven WAN edge devices will replace traditional routers in the branch. The new WAN edge will enable improved security architectures “For years, enterprises have been hamstrung, forced to choose between backhauling all branch office traffic to one of several next gen firewall-equipped hubs or deploying a firewall at every branch site,” said Hughes. “In 2018, the new WAN edge empowers enterprises to make this decision on an application-by-application basis. Network managers can elect to breakout trusted traffic locally at the branch, divert to a cloud-based firewall service or backhaul to a full security stack at a central location. Enterprise-grade SD-WAN solutions also enable enterprises to micro-segment traffic across the WAN, thereby containing the impact of any breach.” Cloud-based management becomes the default Anton Jacobsz, Managing Director of Arbor Networks Jacobsz further refers to a recent blog written by Silver Peak founder and CEO, David Hughes, who also notes that the value of SD-WAN lies in more than just cost savings. Hughes notes the following predictions for the SD-WAN arena in 2018: Enterprises will adopt cloud-first WAN architectures Most WAN traffic, to and from branch and remote sites, is destined for the cloud. However, the traditional WAN was architected for branch-to-data-centre traffic flows, not to efficiently support new cloud- driven traffic patterns. 88 INTELLIGENTCIO Hughes notes that the number of devices under cloud management is growing steadily, expanding beyond Wi-Fi to switching and now to the new WAN edge. “Cloud-based management and orchestration simplify initial deployment, provide better ongoing availability and most importantly are backed with web-scale storage and computer resources that enable analytics and machine learning-based techniques that would be difficult to support in most private enterprise environments,” said Hughes. One Virtual Network Function (VNF) is better than four Ultimately, one advanced SD-WAN-based VNF will provide all the networking services required in a typical branch site deployment. The value of universal CPE will centre on the ability for enterprises to select their preferred technology stack without switching out hardware. The first SD-WAN-driven listing on the stock market Hughes believes that as SD-WAN hits mainstream, the largest independent SD- WAN vendors will likely to be able to pursue an initial public offering (IPO) and list on the stock market. “We can see from the above statements that SD-WAN is gaining traction in the market,” he said. Jacobsz added that the idea of 2018 showcasing the fist listing on a public stock exchange of an SD-WAN would be a symbolic development that would show how far this arena has evolved. “Enterprises are well advised to carefully consider SD-WAN as an optimal solution for their organisation’s ongoing networking development,” he said. SD-WAN technology differentiators include dynamic path control, zero-touch provisioning, cloud intelligence and path conditioning, which ensures private-line performance over the Internet. n “ ENTERPRISES ARE WELL ADVISED TO CAREFULLY CONSIDER SD-WAN AS AN OPTIMAL SOLUTION FOR THEIR ORGANISATION’S ONGOING NETWORKING DEVELOPMENT. www.intelligentcio.com
