Why companies need to implement SD-WAN
SD-WAN (Software-Defined WAN) is an innovative way to create a WAN (Wide Area Network), which ensures an improved performance of applications that use WAN virtualization. It provides a way to centrally control and manage all aspects related to WAN virtualization.
Unlike traditional WAN, SD-WAN provides greater agility and cost savings. The software-defined WAN has its roots in the software-defined network (SDN), with the principle being to bring to the network and transport hardware the characteristics of the applications that use the network.
