SD Cloud (SD WAN)
The software-defined wide-area network (SD-WAN or SDWAN) is a specific application of software-defined networking (SDN) technology applied to WAN connections, which are used to connect enterprise networks – including branch offices and data centres – over large geographic distances.
Many of the new software-defined WAN offerings, for example, can be used to improve and secure internet connectivity, making it more competitive with more expensive legacy WAN technologies such as T-1 or MPLS. In some cases, software-defined WAN technology uses internet broadband connections to replace more expensive solutions. Virtualization technology can apply security and virtual private networking (VPN) technology to broadband internet connections, making them more secure.
The main goal of SD-WAN (SDWAN) technology is to deliver a business-class, secure and simple cloud-enabled WAN connection with as much open and software-based technology as possible.
