At KubeCon 2026 in Amsterdam, Jad El-Zein and John Nicholson sit down with Duffie Cooley, Field CTO at Isovalent, to talk about eBPF, Cilium, Kubernetes networking, and the growing partnership between Isovalent and VMware vSphere Kubernetes Service (VKS).
The conversation dives into how Cilium integrates with VKS as a day-zero add-on, how eBPF changes networking and observability inside Kubernetes, and why technologies like BGP, ECMP, and kube-proxy replacement matter for scalable modern platforms.
Duffie also explains how Isovalent and VMware networking strategies complement each other, how enterprise capabilities extend beyond open source Cilium, and why add-on ecosystems are becoming critical for platform engineering teams operating Kubernetes at scale.
If you’re building modern Kubernetes platforms, exploring VKS, or trying to simplify networking and security operations, this episode is packed with practical insights from one of the pioneers behind the technology.
