Microsoft announced a public preview of cross-cluster networking for Azure Kubernetes Fleet Manager, a feature designed to simplify multi-cluster Kubernetes management. This capability allows services and workloads to communicate across cluster boundaries as if they were local, while preserving cluster-level isolation and governance. The feature is powered by Cilium-based networking and Advanced Container Networking Services, both CNCF projects. According to Microsoft, the solution addresses challenges in managing multiple Azure Kubernetes Service (AKS) clusters by eliminating the need for complex VPNs, gateways, and manual service discovery. Teams can now achieve consistent, reliable cross-cluster connectivity to support scenarios like failover and shared services architectures. The feature also enables unified security and governance, allowing enterprise-grade network policies to be enforced across the entire global footprint. Cross-cluster networking is part of Azure Kubernetes Fleet Manager, which aims to simplify workload propagation and update orchestration. The solution is designed to minimize operational complexity by automating the lifecycle of network components, allowing teams to focus on application delivery instead of infrastructure management. *Source: [azureai](https://azure.microsoft.com/en-us/blog/powering-multi-cluster-workloads-with-seamless-cross-cluster-networking-for-azure-kubernetes-fleet-manager/)*
