KubeCon + CloudNativeCon North America 2024 Co-Located Event Deep Dive: CiliumCon

What do you want attendees to get out of this event? What is new and different this year? What will the day look like? Should I do any homework first? Meet your community! A note from co-chair Bill Mulligan: Posted on September 22, 2025 by Co-chairs: Bill Mulligan and Hemanth Malla CNCF projects highlighted in this post CiliumCon began at KubeCon + CloudNativeCon Europe 2023 in Amsterdam, and this will be our sixth time hosting it. Like Cilium itself, the event has grown significantly since its inception, expanding from its original focus to now include Hubble and Tetragon too. There might even be some nods to scaling networking for the needs of AI. CiliumCon is where the Cilium and eBPF community comes together to share real-world experiences and learn from each other. It’s a space to meet the Github handles you have been working with or following the whole year and who knows, you might even walk away with an eBee. Platform teams will walk away with the knowledge on everything from implementing Cilium Mesh in production environments to advanced DNS policy management to multi-cluster security strategies and running IPv6 only Kubernetes clusters. Seasoned contributors will learn if it’s actually possible to parse DNS in the kernel and everyone will help build the buzz around Cilium. This year, we are celebrating almost 10 years of Cilium! As the project has matured, we’re able to feature the experience of a decade of production implementations. Attendees will hear how CiliumEndpointSlice helped Microsoft unlock higher scale at AKS, SeatGeek’s journey from zero to production in 90 days with Cilium Mesh, ESnet’s pioneering IPv6-first Kubernetes deployment, and Google’s multi-cluster network security strategies with Cilium, Tetragon, and Hubble. We’re also diving deep into kernel-level DNS parsing improvements and will learn how to solve a real-world bug in Cilium’s BPF-based SNAT and its LRU eviction policy. The CIlium and eBPF community will come together for a half-day on Monday, November 10th, from 9:00 AM to 12:30 PM EST. The day will kick off with opening remarks from Program Committee Co-Chairs Bill Mulligan and Hemanth Malla, followed by six technical sessions, and a keynote from Liz Rice which will cover the broader community direction and vision.
