Closing remarks for my third and final CiliumCon as co-chair. A little bittersweet, but one of the things I love about open source is giving other people the opportunity to grow. I'll be in Amsterdam but not as co-chair 🥲

First talk of KubeCon ✅
Liz Rice, Joe Stringer, and I lead a discussion on what projects should think about when trying to write an effective AI policy. Slides are lights on details, but be sure to catch the full recording with all the conversations when it comes out

Working on the eBPF Foundation, I found two eBPF acquisitions I missed earlier this year both in security 🔐
For vendors, eBPF offers a single, programmable layer for threat detection, observability, and enforcement across workloads. I haven't seen any company going against this strategic shift 🐝

Kubernetes networking has gone from “how do we get pods talking?” to “how do we orchestrate distributed AI pipelines across thousands of GPUs with microsecond latency?” And the answer, at least for GKE, is Cilium and eBPF 🐝

or my latest LFX mentorship, I worked with Oluchi Nwenyi to develop technical outcome pages for the Cilium project.
They cover Zero Trust Networking, Network Automation, Cost and Carbon Savings, Multi-Cloud Connectivity, Tool Consolidation and demonstrate to end users to value of using Cilium.

Load balancers always felt like an odd fit in the cloud native world because they sit outside the platform, scale by swapping in bigger boxes, and automation means duct-taping scripts on top.
The Isovalent Load Balancer flips that model.

The kernel has become the most valuable observability real estate and everyone wants a piece of it. F5 announced it’s acquiring MantisNet, an observability company built around eBPF-powered telemetry
Each deal shows that the real battleground will be in the kernel

~60% higher throughput. ~38% lower average latency.
Those are the numbers from a 5G Core testbed running on Kubernetes, comparing traditional socket-based communication with a new eBPF-based implementation called Shared Socket.

A lot has changed in that time, but the overall vision of the project is still very consistent. We just have a more articulate way to say it now 😀
