SD WAN

What is SD-WAN and why do you need it?

To understand the importance of connectivity, let us imagine a day without it. Internet and phone lines are down. Your employees cannot access their mail; your offices cannot make or receive any calls; everyone from the CEO to the middle manager is left twiddling their thumbs as all their cloud hosted data and files are unavailable AND most importantly all your customer-facing applications are offline, turning away innumerable present and potential customers!

That reliable and highly available connectivity (Internet and telephony) is the lifeblood of the business world is irrefutable. In the present hyper-competitive scenario, organizations are increasingly turning to the latest technologies to achieve the best connectivity solutions at the most affordable prices. SD – WAN (Software defined – Wide Area Network) is the newest innovation to optimize WAN technology for faster, flexible and cheaper business connectivity.

SD – WAN explained
Enterprises have been relying on WAN networks to connect their branch offices; to ensure uninterrupted connectivity to remote locations they had to invest heavily in WAN infrastructure and bear the resulting maintenance costs. SD – WAN changed the landscape completely, allowing enterprises to only pay for the functionalities they require with their entire CAPEX investment amounting to small routers.

SD (Software defined) WAN is derived from the Software Defined Networking (SDN) technology, it utilizes software and virtualization technologies to create a WAN network that delivers faster, simpler and cost effective connectivity to businesses. SD –WAN achieves this by decoupling network software controls from the underlying hardware.
