Most SD-WAN providers offer something called hybrid WAN. What that does is routes traffic over both private and public links. These include MPLS links, dedicated circuits, broadband and wireless LTE. This allows administrators to reduce costs by sending low priority data over less expensive Internet paths while using dedicated circuits for more latency sensitive applications like VoIP. The versatile aspect of sd-wan minimizes the need to over provision your WAN reducing costs even more.
