It’s striking the number of service providers that have recently started promoting SD-WAN offers, especially given that there is little evidence amongst them of its commercial success. Popularity and perceived demand are high in the telecoms world, but it seems few service providers have yet to really win over end-users.
Just another example of industry hype? Or is there more to SD-WAN than meets the eye?
There certainly is. Or rather, there will be soon. The increasing move towards a true white-box approach will undoubtedly be the driver in realizing SD-WAN deployments at the CSP and generating real value behind the hype. So, why have they lagged?
The SD-WAN romance
The appeal of SD-WAN is its software-based, flexible and fully programmable nature. The premise of a service delivered using Common-Off-The-Shelf (COTS) hardware offers the illusion of freedom. COTS hardware suggests that users are no longer locked into one solution, as new Virtual Network Functions (VNFs) can be added from a broad choice of third-party vendors.
As there is no ‘one-size-fits-all’ solution, the end-user can be critical and selective of the services it chooses, based on its own budget and requirements. In turn, this means they can benefit from competition, as vendors can battle to deliver more innovative, cost-effective services.
