Cilium

Marino Wijay will make the case at CiliumCon that IPv6 lets AI-scale Kubernetes keep growing since dense AI clusters can exhaust private IPv4 space faster than teams expect. The talk will include production examples and a live demo. See the full schedule: cilium.io/blog/2026/09...

At CiliumConVenkat Gattupalli and Haibing Zhou of OpenAI will share hoe eBPF helped them trace rare packet loss in latency-sensitive inference workloads, and debug and mitigate latency issues. Monday, November 9 | 11:15 - 11:40 AM See the full CiliumCon schedule: cilium.io/blog/2026/09...

Anubhab Majumdar and Vamsi Kalapala will use Cilium Cluster Mesh at CiliumCon to show what makes multi-cluster networking practical at cloud scale, from scoped service export to aligning the data path with network topology. See the full schedule: cilium.io/blog/2026/09...

Liz Rice will give a keynote at CiliumCon about using Tetragon for runtime protection when vulnerabilities outpace patching. The talk will share the latest developments in guardrails and mitigations that can be deployed without downtime. See the full schedule: cilium.io/blog/2026/09...

Kapil Agrawal and Luke Baker of ESnet will return to CiliumCon with an update on running K8s on an IPv6-only network. They'll cover what broke while building out ClusterMesh, BGP, and multi-pool IPAM without IPv4, and how they resolved it. See the full schedule: cilium.io/blog/2026/09...

Join Quang Nguyen and Robin Gögge at CiliumCon next month as they explain how Cilium's sidecarless mTLS works. The session will include a live demo of upstream SPIRE work to bind certificates to a requesting process. See the full schedule: cilium.io/blog/2026/09...

KubeCon and CiliumCon are just over a month away! As you plan your schedule, here's where to find Cilium during the event. There will be end user talks from OpenAI, Walmart Global Tech, and GEICO and from contributors and maintainers on new features. Find the full list: cilium.io/blog/2026/09...

“For AI workloads, network performance directly affects how fast our models train & how efficiently we use our hardware. Cilium offered direct routing without the complexity of managing different networking stacks across our clusters.” How Preferred Networks runs Cilium: www.cncf.io/case-studies...

“Cilium made my job genuinely easier. Hubble tells me what’s happening on the network in seconds. That’s the difference between guessing and knowing.” Read more about why Celonis standardized on Cilium for networking across 150+ Kubernetes clusters: www.cncf.io/case-studies...

Splunk deployed Tetragon across Kubernetes clusters running Splunk Cloud Services to serve as the foundation of its runtime security observability program, replacing 3 existing tools. Today, CPU utilization has dropped by 67% and memory utilization by 74%. Learn more: www.cncf.io/case-studies...

“Everything fits like Lego bricks, you can just enable new features.” - Mikael Johansson Lansberg Learn more about how Etraveli replaced proprietary load balancers and eliminated production downtime with Cilium in a new case study: www.cncf.io/case-studies...

The CFP for #CiliumCon at #KubeCon North America 2026 closes Sun, June 21st. If you're working on #Cilium, #eBPF, networking, security, or observability in #cloudnative environments, we'd love for you to submit a talk. 📝 Learn more: events.linuxfoundation.org/kubecon-clou...

The follow-up to Buzzing Across Space, the illustrated guide to eBPF is now available for #Cilium and goes deep into CNI, Cluster Mesh, Hubble, network policy, service mesh, and Tetragon. It's free to download here 📖 isovalent.com/books/childr...

OpenAI runs #Cilium as its default #Kubernetes networking stack across multiple cloud environments and bare metal. They turned to Cilium for a consistent CNI, L4/L7 policy without sprawl, and Hubble for production visibility. Read the full case study: isovalent.com/blog/post/op...

Kubernetes didn't win because it was standardized. It became the standard because it solved real problems. Watch Bill Mulligan's keynote from CiliumCon Europe 2026, which applies that same logic to what's next: eBPF and Tetragon. 📺 www.youtube.com/watch?v=XQuL...

Can #Cilium's primary CNI run entirely on a DPU? Can it be done with minimal code changes, no added complexity for users, & full hardware acceleration? At the most recent CiliumCon, Vijay Inavolu from Marvell walked through the architecture and performance results ➡️ www.youtube.com/watch?v=S9W8...

It's always DNS. Even at the edge. Roche runs Kubernetes clusters in hospitals and labs where customer-managed DNS won't resolve public domains. See how Cilium quietly intercepts failing DNS requests and reroutes them w/o firewall or app changes. 📺

Hubble flow logs are often the biggest driver of observability costs. A new feature on Cilium 1.19, flow aggregation, was built to address this. 📺 Learn more in this talk from CiliumCon EU 2026: www.youtube.com/watch?v=mXK7...
