Three Reasons why SD-WAN is the Future of Branch Network Infrastructure
Citrix Systems | December 07, 2017
SD-WAN, or software-defined WAN, is exploding at the rate of knots and is the hottest topic within the networking space right now. Estimated to be worth just $225m back in 2015, IDC predicts that sales of SD-WAN technology will reach $1.19bn by the end of this year, and mushroom to $8.05bn by 2021.1 The reason for such explosion is self-explanatory. Increasingly, businesses are moving to a cloud-based environment and setting themselves up as being mobile-first, and SD-WAN is simply better-suited to this evolving landscape than other alternatives on the market. As we near 2018, any business with a substantial number of branch locations or a large volume of mobile workers utilizing myriad devices to access the network, should be thinking seriously about transitioning to SD-WAN if they aren’t already. I’ve heard some industry experts refer to SD-WAN as self-driving, and it’s a comparison I’ve warmed to. Much like the Tesla car, for example, the technology can auto-correct based on deep application analytics and data. There are so many benefits to be had from this and above all SD-WAN eases the increasing strain today’s applications are placing on company networks.
