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

10th September 2024

In case you haven't heard, eBPF Summit is tomorrow. I'm always excited for this event because it showcases all of the new and exciting ways that eBPF is being used. Tune in from 8:30AM-13:00PM PST / 5:30PM-10:00PM CEST.

Speaking of cutting edge eBPF work, the eBPF Foundation awarded $250k to 5 academic projects, here is what they do:

✔ Increasing the security of the verifier with formal verification
🧠 Using eBPF for memory management
🔐 Leveraging hardware isolation instead of the verifier for security
🔬 Making an eBPF runtime for hosting μs-scale applications
😴 Lazy abstraction to enhance the precision of the eBPF verifier

In more conference news, the schedule for Cilium + eBPF Day is also out and I'm excited to be co-chairing the event again. We have end user talks covering edge, multi-cloud, and scaling to zero along with deep dives into the data path like accelerating IPSec 400% and scaling out network policy enforcement. You won't want to miss it. Finally, I'll be heading to the first KubeCon India this fall and I'm looking for an end user company to join me for the Cilium maintainers track session. Just hit reply to this email if you want to help out the community and join me on stage to talk about how you use Cilium. We still have a few more videos to edit before eBPF Summit so let’s 🐝 -gin.
