When SD-WAN was introduced, it was widely seen as an MPLS alternative. Today just about any credible, Internet-based SD-WAN solution can be used to replace a regional MPLS network. The bigger question is what happens the day after you networked your regional offices.
How will your SD-WAN deliver predictable application experience overseas or where Internet routing is unpredictable? How will your SD-WAN adapt to the cloud and mobile users, the new tenants of the modern enterprise? In short, understanding how your SD-WAN will accommodate the unpredictable is essential if you hope to future-proof your WAN.
