It is remarkable to see the growth of software-defined wide area networks (SD-WAN) in the last decade. As predicted when it was first introduced, it is now the cornerstone of modern application-centric networking environments.
According to IDC, managed SD-WAN services are expected to grow at a 21% CAGR, reaching $16 billion by 2026. So it is not surprising that a separate new global study by IDC, sponsored by GTT, found over 95% of enterprises have deployed SD-WAN or plan to do so within the next two years.
