SD-WAN brings big benefits to digital acceleration, including an improved stakeholder experience, simplified network operations, better network uptime, and significant IT cost savings. It allows enterprises to quit router-centric, hub-and-spoke network models reliant on expensive MPLS links. Instead, their branches can connect directly to the cloud via cable/DSL internet, enabling SD-WAN to segment traffic and select the best path.
But, what happens when there are no paths? SD-WAN can’t prevent wired service provider outages. If the cable/DSL service goes down, then connectivity at that branch is lost. Or what if cable/DSL lines don’t exist in a location that needs direct internet access? Enter LTE/5G.
