Public Preview: Cross-cluster networking in Azure Kubernetes Fleet Manager

Azure Kubernetes Fleet ManagerAzure · Containers

Organizations running applications across multiple Kubernetes clusters often face challenges with performance, global service discovery, and observability due to the complexity of distributed microservice environments. Azure Kubernetes Fleet Manager now provides Cross Cluster Networking, delivering a managed Cilium cluster mesh that simplifies configuration and centralizes management of multi‑cluster networking. This capability enables unified connectivity across AKS clusters, creates a global service registry for cross‑cluster service discovery, and supports intelligent routing.

For technical practitioners, this reduces operational overhead by removing the need to manually configure a Cilium mesh, improves scalability and resilience for multi‑cluster deployments, and offers unified observability through shared network metrics and flow logs. It also provides efficient packet processing and reduced latency through eBPF‑based networking.
