Chasing Ghost Traffic: Catching the Cross-AZ Culprit Killing Your Cloud Bill

You scaled your Kubernetes clusters. You optimized your workloads. And yet—your cloud bill keeps creeping up. Hidden in the noise?


Cross-AZ traffic: invisible, expensive, and almost impossible to trace until it’s too late.

This talk is about catching that ghost—before it haunts your budget.
We’ll show how to use eBPF to surface and analyze cross-AZ traffic in real time, tagging flows with just enough context to trace them back to specific services, nodes, and zones—even in fast-changing environments with autoscaling and ephemeral pods. No sidecars. No packet drops. No guesswork.

You'll see how we built a system that gives platform teams the visibility they need to finally control one of the cloud’s most stealthy cost sinks—and even enforce policy to keep traffic local where it counts.
If you’ve ever looked at your network bill and thought, “Where is this coming from?”—this talk has your answer.
