A single switch failure in a cloud provider's network can impact millions of users. So why is it still so difficult to trace the network path of a single customer? While large-scale network monitoring is a solved problem, observing individual tenant flows is not. This talk dives into the complexities of the cloud backbone and introduces a powerful tool for end-to-end flow tracking. You'll learn how this approach helps us rapidly troubleshoot issues and resolve failures that are nearly invisible to traditional, large-scale monitoring systems.
