The WAN looks different than it did a decade ago. This much is obvious.
When I think of benchmarking enterprise wide area network costs throughout the 2010s, I think of customers who wanted to ensure that their carrier—often a single global telco—had lowered MPLS prices along with the market over the life of their multi-year contract.
But this is no longer the blueprint for WAN benchmarking.
Today, many large enterprises have a WAN that includes multiple underlay technologies from several vendors. Cloud apps and services from Infrastructure as a Service (IaaS), Software as a Service (SaaS), and Unified Communications as a Service (UCaaS) are the name of the game.
