Software-defined wide-area network (SD-WAN) solutions transform an organization’s capabilities by leveraging the organization wide-area network (WAN) and also multi-cloud connectivity to deliver high-speed application performance with the WAN side of branch sites. One of several chief benefits of SD-WAN is that it gives a dynamic path selection among connectivity options-MPLS, 4G/5G, or broadband-ensuring organizations can easily and simply access business-critical cloud applications.
SD-WAN solutions have become increasingly popular as organizations request fast, scalable, and flexible connectivity among different network environments, and seek to lower overall sum total of ownership (TCO) while preserving buyer experience. But the wrong SD-WAN solution can significantly inhibit an organization’s capacity to quickly accommodate changing business demands, most famously as it creates new security headaches.
A full SD-WAN solution has several key requirements. First is, although SD-WAN is often considered a substitute for traditional branch routing architecture-and it is-effective SD-WAN solutions go well past branch office needs, with functionality that could include home business office, teleworker use, using one of distributed clouds. SD-WAN solutions should be obtainable in virtual versions designed for multi-cloud environments and hang up up to enable sufficient Software-as-a-Service (SaaS) adoption.
SD-WAN considerations must also include intuitive orchestration, zero-touch deployment options, the opportunity to prioritize critical applications, and also the capacity to self-heal. Finally, SD-WAN solutions must include integrated security-SD-WAN on it’s own is yet another conduit for attackers to breach networks otherwise properly secured-and offer comprehensive analytics and reporting.
