SD-WAN or Software Defined Wide Area Network is a specific application of Software Defined Networking or SDN technology from sd wan companies that’s applied to WAN connections which are being used in connecting enterprise networks including data centers and branch offices over geographic distances.

WAN can be used for connecting branch offices to central corporate network or even to connect data centers that are separated by distance. Back in the past, these WAN connections are often using technology that is requiring special proprietary hardware. SD-WAN movement is seeking to move more of network control into the cloud through a software approach.

Enterprise customers demand more flexibility, open as well as cloud based WAN technologies instead of installing specialized or proprietary WAN technology that is typically more expensive, requires proprietary hardware or fixed circuits. Majority of the new SD WAN offers may be used in improving and securing internet connectivity, making it a lot more competitive with a more expansive legacy WAN technology like the MPLS or T1. In other cases, SD WAN technology is using internet broadband connection to serve as a substitute in more expensive solutions. Virtualization technology apply security as well as VPN or Virtual Private Network technology into broadband internet connections, which makes them more secure so learn more about sd wan.

SD-Wan has the benefit of eliminating the potentially costly routing hardware via provisioning connectivity as well as services through the cloud. The emerging SD WAN technology can be more flexible as well. To give you an example, SD Wan connectivity may be controlled through cloud software, customers can scale up or even burst connectivity during peak demand times.

The primary goal of software defined wide area network is to deliver a secure, simple cloud-enabled and business class WAN connection with as much software and open based technology as possible. This could be used in delivering basic WAN connectivity or it may be used for premium business services similar to WAN optimization, VPN and even ADC or Applications Delivery Control. As a matter of fact, a lot of new startups are after the potential of SD WAN market which is likely around billions of dollars. A big number of these startups have a different approach to their market. For instance, one company may be focused on SaaS or Software as a Service app in the cloud while others however are after branch office connectivity by using SD WAN. According to statistics, there are more or less 360 million dollars that’s been invested in SD WAN startups.
