There is no doubting the impact that software defined networking (SDN) is having in changing traditional approaches to connectivity. Nowhere is this more apparent than in the WAN with software defined wide area networks (SD-WAN).
This combination of cheaper commodity line connections, fast and streamlined hardware, all controlled by remote management software in the cloud is growing fast. In part this is because it offers lower cost, while still being well managed and secure. It also delivers on the software defined potential for truly flexible connectivity and capacity.
