IT infrastructure consists of computers and networks, but in recent years virtualization technology has developed on the computer side, and it is possible to flexibly build and operate virtual servers by setting components such as CPU, memory, and storage in software. It came to be. Similarly, on the network side, SDN can build and operate a virtual network set by software, and SD-WAN has realized this for WAN.
The advantage of softwareization (virtualization) of the network is that the network can be finely and flexibly configured and controlled. Originally, even in one office, the communication required there has various properties. SD-WAN provides more suitable control for each property, which is useful for both users and administrators to realize a network that is easy to use and cost-effective.
