Hubble gives users visibility into every single network packet. You can use the Hubble, either the command line or the UI to see all the packets that you want to see. All of this being generated by eBPF code, so it's extremely sort of performant. We had a really interesting internal demo yesterday about using those metrics to see whether your network policies are working correctly and so on. The next wave will be to actually build even more intelligence into the kernel with eBPF where we actually identify problems.

Episode notes
A few weeks ago, Jerod spoke with Liz Rice about the power of eBPF on The Changelog. Today, we have the pleasure of both Liz Rice, Chief Open Source Office at Isovalent & Thomas Graf, CTO & co-founder at Isovalent, the creators of Cilium.
Around 2014, Facebook achieved a 10x performance improvement by replacing their traditional load balancers with eBPF. In 2017, every single packet that went to Facebook was processed by eBPF. Nowadays, every Android phone is using it. Truth be told, if it’s network-related and it matters, eBPF is most likely a part of it.
