Most likely your Wide Area Network (WAN) has grown in complexity over time or you have inherited a network with its own challenges. Mergers, acquisitions, consolidations, closures, new applications, and new business needs make designing and managing an enterprise WAN a never-ending, complicated task. A task that some say requires the ability to read minds and predict the future. Add in the constant balance between dependability and performance with cost and you have just scratched the surface of architecting and managing an enterprise WAN. Enter into the market, SD-WAN! An entirely new way to look at network architecture, one that focuses on the desired business outcome and not just how the “ones and zeros” get from point A to point B.
