A Software Defined WAN (SDWAN) uses software to make a Wide Area Network more manageable and able to communicate with different input devices and connections. It's more of a communication technology than a physical architecture. A WAN manager used to have to run the network from an dedicated office. Software Defined WAN managers can run the network from any device connected to the network from any location on the network. SDWAN also allows communications in rural areas that may be connected to the WAN via satellite or cellular service.

SDWAN replaces expensive WAN routers in the parts of the network that do not require the full capabilities of the router. SDWAN can be software only, or a combination of hardware and software. Versatility is found in SDWAN's ability to give it's customers exactly what they require and no more. As the customer's needs change at any site in the network, SD-WAN can adapt.

Offices, cloud or dedicated colocation servers, or LANs in Hawaii should consider looking into WAN or SDWAN for expanded networking requirements.
