Swapping a traditional wide-area network (WAN) for a new kind of branch and remote-location network connectivity — software-defined WAN (SD-WAN) — reduces operational costs and improves resource usage as well as security.
In my last post, I described why this is true and enumerated several SD-WAN approaches, including appliances, software licensing, SD-WAN as a service, and SD-WAN managed services.
But which sort of SD-WAN capability is right for you? Approaches break down into two types: do it yourself or turn to some sort of SD-WAN service.
