The goal for eBPF was never “better Linux networking.” It was creating a new control abstraction or in the words of Kelsey Hightower, a platform for building platforms. We now have policy that spans VMs, containers, and bare metal, runtime enforcement on Windows and Linux, making middleboxes obsolete by embedding their logic directly into the system, or even just protecting a Minecraft server.
By rebuilding the foundation, we can reshape how we think about what we build on top, like the way Cilium implements Gateway API or how we fight DDoS attacks. I've got the rebuild my bike for an upcoming bike packing trip to the south of France so let’s 🐝 -gin.
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
