Expensive hardware upgrades, lack of easy provisioning, inability to rapidly scale up/down, and multi-service provider relationships with vendor lock-ins, are driving up costs and complexity. For decision makers who are constantly scouting for better alternatives, what’s the way out? Enter SD-WAN. Based on the state-of-the-art technology - software-defined networking (SDN), it provides secure and scalable architecture at a much lower TCO. SD-WAN also seamlessly connects business branches, without the hassle of deploying additional systems, manual MPLS upgrades, or dedicated IT teams at individual locations. This paper takes a deep-dive into the need for network transformation, how to leverage SD-WAN to deliver on its promise, and who should drive the transformation.
