Cloud . Big data . Mobile. Social networking. These are some of the core ideas driving the new generation of critical consumer and business applications — but do they really have the modern network infrastructure they need? The basic way networks are managed — even in an architecture like a cloud — has remained largely unchanged from a decade ago in that most network connections continue to be initiated, operated, and closed by technicians working at the hardware level, who oversee network devices such as switches, each managed in a proprietary way. Such an approach means that implementing any change in the way data flows from point A to point B is slower, more complex, more costly, and less secure than it should be.
A cloud, for instance, is less dynamic than it should be in allocating more bandwidth to services that need it due to workload spikes (such as social networking or big data). And those services in turn generate less value than they should. So increasingly, in a world where traditional networking approaches have become too complex, closed, and proprietary, forward-looking organizations are searching for a new way to centralize, accelerate, secure, and scale network management. That new way is software-defined networking (SDN) which is designed to solve just these challenges and even more !
