Networks, servers, etc. do not matter if network performance monitoring and management is ineffective. The implementation of SDN and NFV requires dynamic creation of resources, increasing the importance and the difficulty of effective performance monitoring and management.

At the end of the day, a company's business unit managers could care less about networks, about servers, about storage. What they care about is the handful of applications they use to run their business unit. In that context, while not being dismissive, networks, servers, storage, all the infrastructure does not matter if we can't do effective performance monitoring and management, ideally, to understood the source of the degradation before it impacts the user, sometimes that's possible, sometimes it's not. But certainly to do rapid root cause analysis to identify and eliminate a problem before it causes too much damage. Causes the company to lose revenues, customers, et cetera.

As we move to SDN and our NFE, which means more dynamic creation of resources, that increases, I don't think it's hyperbole, by an order of magnitude, both the importance and the difficulty of effective performance monitoring and management, because resources are being created, used, consumed and then torn down.

Being able to do any kind of a troubleshooting activity in that kind of an environment is extremely demanding, and yet no one is going to say, gee boss, good news, bad news. Good news, implemented SDN, NFE will save costs, boy are we agile. Bad news, when the performance of one of our critical applications goes badly, we have no idea what the cause of that is. That's totally unacceptable. I would suggest that both the importance, and the difficulty is increasing dramatically.
