performance of those applications all the way through. At the same time, POP-based SD-WANs can be great for site-tosite traffic as well, argued Arnstein. “Often, POP-based SD-WAN providers have deployed these POPs globally, which can be a game-changer for global enterprises with a lot of site-to-site traffic,” she continued. “This is because of the middle mile that’s included in most of these platforms.” POP-based solutions are especially valuable globally, said Arnstein, between countries or continents where the internet backbone is not as reliable. “This means that if a user in Europe needs to access an application hosted in the USA, they can use that middle mile to give them the most efficient route possible to get there,” she continued. POP-based also is one of the few instances where SD-WAN can be useful with just one circuit, advised Arnstein. “Even with one circuit, the traffic is optimized over the middle mile, because of the network backbone.” Businesses utilizing a POP-based or NaaS solution, said executives at Aryaka, “can rely on a fast and secure private core network without having to build out a heavy infrastructure and manage additional hardware at the edge, making it simple to expand branch offices or move locations as they please, without compromising on reliability, and application performance, or security.” Aryaka is a leading provider of this type of architecture, along with Cato Networks, Masergy and Bigleaf. o For those interested in further discussing the SD-WAN market opportunity, we’ll be taking a deeper dive into selling these three types of SD-WAN during a panel session at our upcoming CVx event in Scottsdale this November. We look forward to seeing everyone this winter in the desert.

So far, 11 percent of respondents to Aryaka’s survey have deployed SD-WAN, and when respondent were asked what features they want integrated into their SD-WAN solutions, “cloud and SaaS connectivity” (36%) topped the list, followed closely by advanced security features and support for remote and mobile workers. A similar third said a “fully managed service” was a desired feature. On the flip side, top barriers to adoption included skills gap (31%), again followed very narrowly by cost, application performance, complexity and concerns about the maturity of the technology. In an ideal world, what features would you want integrated in your SD-WAN solution? 2022 2021 Cloud and SaaS connectivity 36% 36% Advanced security features 33% 32% Support for remote and mobile employees 33% 31% Fully managed service 32% 28% WAN optimization and application acceleration capabilities 32% 32% Private connectivity that can completely replace MPLS 28% 28% Routing 24% 22% Network functions virtualization (NFV) at branch to replace appliances 22% 26% QoS 16% 14% Network and application visibility portal 8% 6% Source: Aryaka SOTW Moving forward, more than a third of survey respondents are at the information gathering stage, about a quarter are actively evaluating vendors and 18 percent have built a business case. “The trend from last year is more of a focus on the later stages of the process, with the business case stage in particular growing from 14 percent,” Aryaka researchers pointed out. When undergoing a WAN transformation, including to an SD-WAN architecture, more than two thirds of enterprises plan to leverage a managed service, while 19 percent expect to take the DIY approach.
