These large public clouds are becoming part of your “enterprise network” by default. A coherent plan to route traffic is rquired. And that’s where SD-WAN comes in. With SD-WAN, one can intelligently route traffic and improve network performance of these cloud applications. And with more and more of this happening, SD-WAN will continue to evolve.
