When I first entered the networking industry right out of college, many applications sent passwords over the network in clear text, unencrypted. This made accurately monitoring latency and packet loss to some applications impossible. Getting all the DNS logs is often impractical. Well, that didn’t last long.

The lack of a global, SLA-backed backbone leaves SD-WANs unable to provide the consistent, predictable transport needed by real-time service and business-critical applications. As a result, SD-WAN adopters have remained chained to their MPLS services, paying exorbitant bandwidth fees just to deliver these core applications.
