Depending on what applications you software defined networking for, there are many ways to look at it across the industry. It could be in the campus and branch. It could be in the data center. It could be across the wide area in various cloud environments. However, a general notion of what to keep in mind is that software defined networking is centered around the notion that things like mobile and cloud are having a big impact on infrastructure, making it more dynamic, distributed, and automated.
There's a lot of ways to look at SDN. I think that's been a little bit of the challenge of the industry. A lot of folks had different meanings for SDN and it served different domains. It could be in the campus and branch. It could be in the data center. It could be across the wide area in various cloud environments.
I think what we've settled around is more around the impact that things like mobile and cloud are having on infrastructure which is to say it's a lot more dynamic, a lot more distributed, a lot more automated, a lot more based on open source and open interfaces. A lot more automation brings with it a higher degree of control which may be control from administrators but more often is sort of self-service provisioning of the users.
If you go to AWS or Google compute engine and you grab the resources, you're instantly given access to infrastructure that's in the cloud. That's an expectation that a lot of people have about things like SDN that are highly software driven as opposed to needing a truck roll to install a server, an appliance, a router or switch. I think that's one of the biggest changes and evolutions for the industry.
