All of us depend on the underlying network to be stable whether in the datacenter or in the cloud. We all have a basic knowledge of how traditional networks run, however in the past 10 years, we’ve moved to building redundant physical topologies in our networks, optimized the routing methodologies accordingly, moved into the cloud and gotten greater visibility and tuneables in the Linux kernel network stack. A lot has changed!

However, the way we troubleshoot the network in relation to the applications we support hasn’t adapted. In this session, we’ll review the progress that network infrastructure has made look at specific examples where traditional troubleshooting responses fail us and demonstrate our need to rethink our approach to making applications and the network interact harmoniously.
