SDN Makes Application Performance Correlation Easier

Comments: 0 Runtime: 1:20 Posted: April 13th, 2015

In the old world, there are disconnects between the application performance and the underlying network. With SDN, it’s easy to correlate when troubleshooting because you’re already application-aware. If your page refresh takes too long, you can immediately correlate that issue to part of the network and develop rules to route around the problem.

Before, in the old world, you had an application, and then you had the disconnect, and then you had the network. You can monitor the network, but you don't really have a visibility on how the application is doing. Basically the people using the application and deploying it will report a problem, and then there's some correlation that has to happen between the two.

What as the end, it's easy to correlate because you're application aware, the network is application aware, that correlation is automatically done. If your page refresh is taking too long, you can immediately correlate that to a specific part of the network, your network, and then you can actually, because that's programmable, you can actually work, develop tools to automatically reroute around those problems.

Because the network is programmable, and because the network provides so much information, you can automatically, if this happened, then do this. As opposed to before, it was like, it takes time to correlate, and then you have a committee of the security guy, the network guy and the application guy to decide on what's the best course of action.
