 eCHO news is your bi-weekly wrap up of all things eBPF and Cilium. If you want to keep up on the latest in cloud native networking, observability, and security this is your quelle

12th March 2024

 

Cilium + eBPF Day (and the side event KubeCon + CloudNativeCon ;) is next week! Of the things I currently remember, I have opening and closing remarks to write, a developer summit to organize, and a booth schedule to plan. And that is barely scratching the surface of everything that is happening around Cilium and eBPF at KubeCon. If you want to see everything you can find at the events, check out the Cilium blog. There you'll also find the 26 talks about Cilium!

 

If you are in Paris next week, be sure to say hi and finally find out if I'm a real person or some advanced Cilium AI functionality. Mention the newsletter and you might even get some stickers. And while Cilium has already passed the graduation milestone so there wont' be any cake this time, the project is only accelerating, recently becoming the 3rd fastest project in the CNCF. There will be lots to catch up on (and still prepare) so let's 🐝 gin!
