SD-WAN

SD-WAN - Software Defined Wide Area Network

What is SD-WAN

Software-defined WAN (SD-WAN) is a technology that distributes network traffic & applications across wide area networks (WAN) & Cloud Services in a more intelligent manner than traditional routing. It uses software-defined networking (SDN) concepts to automatically determine the most effective way to route traffic to and from branch offices and data center sites.

SD-WAN is the future of enterprise networks. It is rapidly disrupting conventional WAN architecture due to the multiple benefits it delivers. Gartner predicts that 80% of enterprises will be using SD-WAN by 2020. SD-WAN offers significant cost savings over traditional WAN methods while improving the security, availability, performance of your WAN connectivity and critical applications. What’s not to Love!

In addition, SD-WAN addresses the challenge that most organisations face in transforming traditional internally focused infrastructure into a cloud optimised configuration. This is achieved by utilising SD-WAN to deliver secure local branch breakout via it’s inbuilt stateful firewall. Local branch complexity can also be reduced significantly as routers and firewalls can be replaced. With SD-WAN, users can seamlessly access cloud based applications direct from the branch without backhauling data through the data centre and still access the data centre for accessing legacy applications, securely and in the most efficient manner possible.
