Microsoft has announced the public preview of cross-cluster networking for Azure Kubernetes Fleet Manager. Built on Cilium and eBPF, it enables transparent east-west connectivity between AKS clusters without VPNs, gateways, or proxies. Key features include global service discovery via a simple annotation, unified multi-cluster observability, identity-based security policies that span cluster boundaries, and zero-touch lifecycle management. Prerequisites are Azure CNI powered by Cilium and Advanced Container Networking Services. Setup involves joining clusters to a Fleet, associating them with a cross-cluster network profile, and annotating services as global.
