Modern performance monitoring will play a critical role in SDN since an understanding of the environment through baselining is necessary in order to establish high-level policies.
The role of performance monitoring in SDN is critical. A lot of this notion of opening up information from the network to, not just the network administrators, um, is really at the heart of why people care about things like SDN. You know, a lot of the folks want more granularity for application performance management. They want more, in terms of how do we set up policies for the infrastructure environment to begin with. And that requires a lot of base lining and understanding the existing environment so that policies can be set at a higher level, and tweak overtime what we have some customers that are actually doing machine learning on their existing policies in the operations environment.
And because they, you know, have so much data that they can work with, those policies get tighter and tighter over time. So I think it plays a critical role as you think about, you know, networks used to be very much set and forget. There wasn't a lot of dynamic configuration and automation, in that environment and the industry kind of grew up with, you know, a device level CLI for changing the network configuration. And the world of SDN that's highly automated, so you may not have any human no matter where you know in the flow, but, those then those administrators are much more involved in a broader pro not just in the network domain. But, you know, interacting with the other aspects of the IT infrastructure in the applications team. So there's a lot more complexity, and I think the role of monitoring and its role and sort of this feedback loop and control and automation becomes absolutely critical.
