In our last post [Software-Defined WAN: Cheaper, Faster, More Secure], we discussed how software-defined WAN (SD-WAN) solutions enable you to reduce WAN cost and complexity while increasing performance, reliability and security. The software-defined component of SD-WAN lies in a smart centralized controller capable of differentiating and segmenting traffic and making routing decisions on the fly.
The IT industry is often guilty of hype and oversimplification. New technologies are marketed in a way that creates overinflated expectations, while the potential challenges associated with implementing and managing the technology are minimized. Software-defined WAN (SD-WAN) technology has, for the most part, lived up to the hype.
