According to Cisco, 80% of corporate network changes are still done manually, and 70% of corporate policy violations are human factors. As a result, 75% of IT operating costs are related to changes and troubleshooting, with the latter accounting for nearly half (43%) of maintenance staff time. The use of SD-WAN radically changes this situation, since in a software-defined network there is no need to configure each device separately using the command line - the necessary settings are automatically scaled to all network nodes. Thus, now, to connect new equipment, it is necessary to perform the minimum steps (connect, apply power, establish a connection), further configuration takes place automatically.

Obviously, SD-WAN offers the opportunity to significantly reduce the time spent on deploying infrastructure in new branch offices, since settings that were previously performed manually are now automatic. Previously, the connection could take several days due to the need to send an engineer on a business trip to configure the equipment on site, says Julia Andrianova, Cisco Enterprise Solutions Development Manager.: "Now any non-profile specialist can connect the router, after which the device downloads the settings by itself. Thus, the network is configured in a matter of minutes. If earlier it took at least three days to connect one branch, now in a few minutes you can connect dozens of branches. In our practice, there was a case when a large bank deployed the infrastructure of 50 branches in one night ”.

The second advantage of SD-WAN is the optimization of the work of applications delivered according to the SaaS model , since companies are not always able to provide high-quality "transport" to the cloud. Software-Defined Networking allows you to increase control over the quality of applications on the network. "Many of our clients, who have implemented SD-WAN, have significantly increased the quality of their applications while reducing the bandwidth of the communication channel purchased from telecom operators,” Yulia Andrianova shares her experience. "Dynamic traffic balancing helps to achieve these results, which takes into account the needs of mission-critical applications."
