WAN providers in Kentucky have less expensive service thanks to Software-defined Wide Area Networks which replace costly routers with software/hardware combinations. Networks do not require the full capablities of the routers with SD-WAN.  As business needs change at any site in the network, SD-WAN is an adaptive technology that can adapt without the need to replace expensive hardware.  Businesses that have offices, cloud or colocation servers, or more than one metropolitan area should consider looking into WAN or SD-WAN providers for their data netwoking needs.
