Industry research is pegging SD-WAN for serious growth. While, software-defined WAN is still in its infancy, it is making a mark. So much so that independent organizations like Frost & Sullivan is singing SD-WAN’s praises, and IDC is expecting a CAGR of nearly 70 percent through 2021, which would put a value of more than eight billion dollars on the market. But why is there so much hype behind this young technology?




The benefits of migrating to SD-WAN are aplenty, and allow me to illuminate why the ceiling is so high. Let’s start security. By possessing increased visibility and control, a central provisioning system, encrypted network traffic and the ability to segment network traffic promises improved security in a high-performing WAN. Take Versa Networks for example leveraging a holistic approach to security, its solution is a fully integrated offering, with security in its DNA.

With an SD-WAN deployed, IT can easily view the network to troubleshoot and pinpoint trouble points without negatively affecting the user experience. Coupled with centralized orchestration, network management is now far more user friendly.

The cloud is empowering our SaaSy era, and an SD-WAN solution is an easy way to gain cloud access, and based on SLAs put in place, one can assure performance – to the tune of reduced packet loss, jitter and latency.

A key benefit of SD-WAN is its architecture, as it is capable of supporting branch office operations, with increased security and optimized branch connectivity, resulting in an improved user experience and application performance. And because by nature, SD-WAN is a virtual overlay, it enables hybrid solutions and a great deal of flexibility. It’s scalable too! Scalability is easily addressed for new sites and connections due to SD-WAN’s inherent automation.

Curious about how SD-WAN stacks up pricewise? The quick ROI is real, one provider promises up to 90 percent in the first three months of deployment. Industry events offer an educational look at this burgeoning technology. As adoption continues to rise, more are taking the time to dive into the world of software-defined networking solutions and do due diligence.

Put simply, digital transformation is driving change, and SD-WAN is rapidly stealing the show. The cloud is no passing fad, and software-defined networking solutions seem set to evolve IT operations.
