cluster roles¶
DaoCloud Enterprise 5.0 classifies the roles of clusters based on their different functional orientations to help users better manage IT infrastructure.
Global service cluster¶
This cluster is used to run DCE 5.0 components such as container management, global management, observability, registry, etc. Generally, no business load is carried.
