Software-Defined Wide Area Network (SD-WAN) has been commanding a lot of attention lately, and rightly so. Network traffic is increasing by 30% year-over-year, and by 2020, there’s projected to be 1.2 billion mobile-connected devices. The increase in traffic means that traditional wide-area networks (WANs) are being pushed to their limits, especially in organizations with multiple locations. To alleviate unprecedented demands from mobile users, security threats, and cloud applications, more organizations are turning to SD-WAN. SD-WAN offers a better approach to WAN connectivity by solving the digital transformation challenges of traditional WAN architectures.
