When Does SD-WAN Make Sense?
Networkworld, March 13th, 2023
Software-defined WAN offers a lot of potential benefits including price, efficiency, and performance, but it's not right for all sites.
This is an important question, with a simple answer: it depends. And the main thing it depends on is, why an organization wants an SD-WAN in the first place. Answering that goes a long way to answering the size question.
The baseline assumption is that the IT department sees a need for the organization to have a iprivate WAN, rather than every site communicating solely over the public internet.
