 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

19th September 2023

 

Last week was eBPF Summit and in case you missed it all of the talks will be coming out on YouTube shortly. It covered everything from auto-tuning the Linux kernel to how eBPF is changing Android networking to augmenting endpoint security. My favorite talk was from Jean Yang about "A Vision for eBPF Everywhere". In it, she talked about how when Akita (her company) used eBPF in their messaging to developers, they actually saw conversions go down because developers were afraid of having to learn a new technology. When Akita instead started talking about what eBPF enabled like no instrumentation observability and low overhead, their message started to resonate and drive interest.

 

I think we are at a similar inflection point for Cilium. We are moving beyond just the technologist adopters who choose Cilium because its use of eBPF will help future proof their platform toward the mainstream adopters that want Cilium because of what it enables in their clusters and beyond. They want solutions to their problems rather than a technology to learn and that is exactly what eBPF is enabling, even if they don't know that it is the underlying engine. This transition is also reflected in Cilium progress from Incubation to Graduation in the CNCF and I couldn't be more excited for our future as a project. I've got a press release to write so let's 🐝 gin!
