Can someone please define SDN?

Can someone please define SDN?

When the “Software Defined Networking” buzzword first emerged from the halls of UC Berkeley back in 2008, the definition was simply the separation or abstraction of the data plane from the control plane for all network elements. ┬áMeaning that my data plane (read: switches, routers, firewalls, load balancers, etc) are all API driven/controlled from a centralized control layer (the control plane). The control plane is in turn driven by the management interface (the management plane). As is typical of the general IT market, this fairly simple to understand concept has become obscured almost to the point where it can mean different things to different people. I want to try to shed some light on how I see the SDN landscape evolving. Please understand that this is my take on this subject, and your mileage may vary. This is a dynamically evolving space, and as vendors work to come up with ways to sell you things that fit within the SDN arena, it seems like each approach is slightly different...

It has evolved and become a standard in most corporations for a very good reason: change control, and a need for a defined scope of responsibilities. This environment however is no longer viable in the world of cloud computing. When the user has developed the taste/need for instant gratification, they expect that their workload will be made available to them in minutes. Not the days or weeks it takes to get through the red tape and change control processes inherent in a strictly siloed environment. If IT cannot move at the speed of business in this case, guess what, I’m just going to pull out my procurement card and go to...
