 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

26th March 2024

 

The week after KubeCon and the energy around Cilium is still buzzing in my head! If you want to get a little feel for it, check out the tweet at the bottom of people spilling out of Dan and Nico's intro to Cilium talk. Apparently 1,600 people added it to their schedule 🤯 It was the same for many of the talks about Cilium and Cilium + eBPF Day was standing room only when Laurent and I kicked it off at 9am on a Monday.

 

At the Cilium booth, there were also many people asking about specific features and how to implement them in a POC or production rather than just asking what Cilium even is. At this point, the community seems like a runaway freight train. I'm running away from work this week to bike around Sardinia so let's 🐝 gin!
