Software-defined WAN is the future of networking, and many enterprises are showing an interest in the technology. IDC has predicted that the SD-WAN market will hit $6 billion by 2020. Rightfully so, because there are so many benefits to be gained through this new approach to wide-area networking.

First, you have to find the right motivation for an SD-WAN deployment and convert this motivation into a business case.
