It is hard to have a software defined networking (SDN) conversation without discussing Software-Defined WAN (SD-WAN). SD-WAN is the leading SDN use case for businesses breaking free from the chains of traditional Wide Area Networks (WANs) from the likes of Cisco Systems or Riverbed Technology. A WAN is a connection between two networks and an SD-WAN is an overlay on top to better manage that connection. The promise of SDN is to remove networking barriers which still create a highly manual, complex process. The complexity of networking and network security leads to deployment delays, holding your company back while trying to move quickly to take advantage of new opportunities. With virtualization, servers can be deployed in minutes, but the network and security then takes weeks, if not months. This limits business opportunity and puts a clamp down on profit upside from new ideas.
