BrandPost: Branch Office SD-WAN Availability: Last-Mile Considerations

MPLS is showing its age in the era of digital transformation. SD-WAN’s agility, low cost, and direct branch office cloud access increasingly make more sense for global, cloud-enabled organizations. The big question for many IT leaders is: Can  SD-WANs and their Internet last-mile connections match MPLS’s availability to serve as an MPLS alternative?
