Cloud Native networking, observability, and security with Cilium, eBPF, and Isovalent

Newsletter cilium.io/newsletter
My alma mater uses Cilium 🐄 I wonder if these clusters help with ice cream production 🍦

"Cilium has been phenomenal. We started with core networking, added Hubble for observability, Cluster Mesh for cross-cluster communication, and are exploring Tetragon"

eBPF dev room schedule for FOSDEM 2026 is out 🐝

eBPF has become a normalized building block for infrastructure so if you want a single room that spans kernel internals, language tooling, observability, and networking, I'll see you in Brussels over a beer 🍻

Happy 10th Birthday, Cilium! 🎂

One decade ago, Thomas Graf pushed an initial commit with just a LICENSE, a .gitignore, and 226 lines of code. There was no Hubble, no Cluster Mesh, no network policy, no Tetragon, and eBPF still had a logo with a pea pod in it.

I'm at Linux Plumbers Conference in Tokyo this week to talk about what the eBPF Foundation accomplished this year and get feedback from the community on what we should focus on next

If you can't make, let me know what you think is currently holding eBPF back so the foundation can work to fix it 🐝

"The infrastructure equivalent of dark matter" 🐝

I love this take on eBPF from @rawkode.dev This is also exactly why Cilium has become the default. The future of Kubernetes networking is eBPF-powered. It's not even a debate. It's just physics 😉

Results from the Cilium User Survey are in and it shows how we are moving from plumbing to platform. The networking conversation has moved from connectivity to topology where cluster mesh and network policy are what truly turns Cilium into a platform.

10,000 raw events ➡️ 1 useful alert turns eBPF from a firehose into a funnel

If you try to ship every kernel event to userspace, you are killing the system rather than observing it. You need In-Kernel Filtering, Ring Buffers and User-Space Windowing
10,000 Events to 1 Alert: Don’t burn the CPU
In my last post, I wrote about replacing polling with tracing.
