Hub of Hubs

---

Hub of Hubs provides multi-cluster management at very high scale.

Hub of Hubs utilizes several standard RHACM hub clusters to provide cluster-management capabilities, such as applying compliance policies to managed clusters and monitoring compliance status, or managing application and cluster lifecycle, while addressing the scale and performance requirements of edge use cases.

Our simulations showed that a Hub of Hubs is able to manage one million clusters with hundreds of policies and/or applications applied to each cluster.
