Since its inception, software-defined networking (SDN) has primarily been viewed as a tool, driven in part by its fast acceptance through web-scale datacenters. But in reality there is an opportunity outside of the datacenter for SDN.
Everyone is talking about “Hybrid Clouds” but the definition is as stable as a house built on a beach.

But customers will have a mix of public and private.
