Cluster Roles

DaoCloud Enterprise 5.0 classifies cluster roles based on cluster functions to help users better manage their IT infrastructure.

Note

A cluster can have multiple cluster roles. For example, a cluster can be a global service cluster, a management cluster and a worker cluster at the same time.

Global Service Cluster

This cluster is used to run DCE 5.0 components, such as Container Management, Global Management, Observability, Container Registry, etc. As a best practice, it's not recommended to run business applications in this cluster.

You can have only one Global Service Cluster in a DCE 5.0 platform.

Management Clusters

This cluster is used to manage worker clusters. As a best practice, it's not recommended to run business applications in this kind of clusters.

You can have one or more management clusters in a DCE 5.0 platform.

  • Classic Mode: deploy the Global Service Cluster and management clusters as different clusters, designed for enterprises with multiple data centers and architectures.
  • Simple Mode: deploy the Global Service Cluster and management cluster as the same one cluster.
