Instead of hardware, a software-defined wide area network (SD-WAN) uses software and virtual network overlays to take advantage of available WAN connections to connect your enterprise networks over multiple sites in different locations.
If your organization has multiple branch locations or a large number of mobile workers using different devices to access the network, you should be thinking seriously about transitioning to SD-WAN if you aren’t already. Flexibility and cost control are key business drivers.
The largest expense for any WAN infrastructure are circuit and service costs.
SD-WAN manages your available network routes that deliver an application’s required quality of service. When cheaper Internet links are available, more traffic will shift onto them and off more expensive MPLS links, which can then be reduced or eliminated.
