CiliumCon

Cilium is an open source, widely-used, and highly scalable cloud native networking, observability, and security solution based on the kernel technology eBPF, that connects workloads in Kubernetes and beyond. CiliumCon focuses on how Cilium and its sub-projects Hubble and Tetragon are being developed, deployed, and used across the cloud native landscape to revolutionize cloud native platforms.

At CiliumCon you’ll hear from end users sharing how Cilium, Hubble, and Tetragon unlocked levels of scalability, performance, and security that weren’t possible before and from contributors who will teach you how Cilium is leveraging eBPF to deliver these benefits. From Cilium and eBPF internals to how Cilium, Hubble, and Tetragon are helping businesses achieve their goals, you’ll hear it all at CiliumCon. Dive deep into the world of high-performance networking, transparent security, and scalable observability at CiliumCon!
