How Microsoft is governing thousands of Kubernetes clusters without manual intervention

Microsoft is using Azure Kubernetes Fleet Manager to manage Kubernetes at fleet scale across thousands of clusters.

Clusters are grouped into stages so updates can roll out sequentially and more safely.

Cilium Cluster Mesh provides cross-cluster networking and connectivity across the fleet.

The approach addresses the limits of single-cluster GitOps as deployments expand across cloud, on-prem, and edge environments.
