Software-defined wide-area network (SD-WAN) is a special application form of software-defined networking (SDN) technology that is applied to WAN connections, which are used to connect corporate networks including branch offices and data centers that have geographic distances. large.
For example, a WAN is used to connect branch offices to a corporate network center, or also to connect data center locations that are quite far away. In the past, WAN connections were used for technology that required special hardware. Currently SD-WAN seeks to move control of the network to the cloud, using a software approach.
Impact of SD-WAN for business
Companies are demanding something more flexible, such as cloud-based WAN technology, rather than having to install an expensive dedicated device.
What SD-WAN offers is enhancement and security in internet connectivity, and makes it much more competitive than the quite expensive WAN technology. In certain cases SD-WAN uses a broadband internet connection to provide a cheaper solution.
SD-WAN also has the advantage of eliminating the potential for costly hardware usage by providing connections and services via the cloud. Using SD-WAN technology also increases flexibility.
The main objective of SD-WAN technology is to provide a secure WAN connection with an easy cloud system and with as many possibilities for open software as possible. It can be used to provide basic WAN connectivity, WAN optimization, and applications delivery control (ADC).
