Policy Management Supports network policies, quota policies, resource limits, disaster recovery policies, security policies

Management Cluster

This cluster is used to manage worker clusters and generally does not carry business workloads.

  • Classic Mode deploys the global service cluster and management cluster in different clusters, suitable for multi-data center, multi-architecture enterprise scenarios.
