Jayshree Ullal | VMworld 2012
Jayshree Ullal, President and CEO of Arista Networks, took the spotlight in TheCUBE here at VMworld 2012 to explain once again that despite popular perception, software-defined networking isn't only sexy -- it's the future of applications (full video below). There's an emerging awareness that as much cloud-based, data-driven applications can build business value, there's a serious bottleneck in terms of application topology. Different network layers with varying latency levels cause a huge drop in I/O between components, causing performance problems and creating massive headaches for the CIO. But that's where Arista comes in, Ullal says. With software-defined networking, you can create a "flat" application topology that goes a long, long way towards solving that bottleneck. The advantage of converged infrastructure, virtualization, and all the other good stuff that we've been talking about at VMworld 2012, is that every aspect of the stack is programmable and flexible. That, in turn, enables a whole new breed of application, including big data, web 2.0, high density compute, and so on -- applications that wouldn't have been possible without marrying the higher I/O rate to the scalability and flexibility that modern infrastructure can grant. Basically, programmable, software-defined networking is the glue that holds the next generation of IT together.
