OVERVIEW OF SD-WAN EVOLUTION

SD-WAN is an acronym for software defined – wide area networking. Most IT professionals and staff have experience with a traditional wide area network (WAN), defined as a network that exists over a large geographical area and connects to smaller local area networks (LANs). In addition, a WAN ensures that computers and users in one location can communicate with computers and users in other locations.

However, as enterprises move their back office support workloads, communication, collaboration, marketing, and sales solutions to the Cloud i.e. cloud-based SaaS solutions, organizations are realizing measurable savings in time, money and less exposure to human-error.

Hence, the adoption of SD-WAN is a direct result of the rise in businesses moving more of their applications to the Cloud.

In an SD-WAN environment, implementation of changes or updates is done automatically so that users are completely unaware of the impact on their application usage. Network issues are automatically corrected based on quality metrics with little to no performance degradation versus in a traditional WAN environment.
