Ever tried solving DNS security across a multi-cloud, multi-cluster Kubernetes setup? In this episode recorded live at KubeCon, Ashish chats with Nimisha Mehta and Alvaro Aleman from Confluent's Kubernetes Platform Team.

Together, they break down the complex journey of migrating to Cilium from default CNI plugins across Azure AKS, AWS EKS, and Google GKE. You’ll hear:

• How Confluent manages Kubernetes clusters across cloud providers.
• Real-world issues encountered during DNS security migration.
• Deep dives into cloud-specific quirks with Azure’s overlay mode, GKE’s Cilium integration, and AWS’s IP routing limitations.
• Race conditions, IP tables, reverse path filters, and practical workarounds.
• Lessons they’d share for any platform team planning a similar move.
