# Differences between Resource Groups and Shared Resources Both resource groups and shared resources support cluster binding, but they have significant differences in usage. ## Differences in Usage Scenarios - Cluster Binding for Resource Groups: Resource groups are usually used for batch authorization. After binding a resource group to a cluster, the workspace administrator will be mapped as a cluster administrator and able to manage and use cluster resources. - Cluster Binding for Shared Resources: Shared resources are usually used for resource quotas. A typical scenario is that the platform administrator assigns a cluster to a first-level supplier, who then assigns the cluster to a second-level supplier and sets resource quotas for the second-level supplier. ![diff](https://docs.daocloud.io/daocloud-docs-images/docs/en/docs/ghippo/images/res-gp01.png) Note: In this scenario, the platform administrator needs to impose resource restrictions on secondary suppliers. Currently, it is not supported to limit the cluster quota of secondary suppliers by the primary supplier. ## Differences in Cluster Quota Usage - Cluster Binding for Resource Groups: The workspace administrator is mapped as the administrator of the cluster and is equivalent to being granted the Cluster Admin role in Container Management-Permission Management. They can have unrestricted access to cluster resources, manage important content such as management nodes, and cannot be subject to resource quotas. - Cluster Binding for Shared Resources: The workspace administrator can only use the quota in the cluster to create namespaces in the Workbench and does not have cluster management permissions. If the workspace is restricted by a quota, the workspace administrator can only create and use namespaces within the quota range. ## Differences in Resource Types - Resource Groups: Can bind to clusters, cluster-namespaces, multiclouds, multicloud namespaces, meshs, and mesh-namespaces. - Shared Resources: Can only bind to clusters. ## Similarities between Resource Groups and Shared Resources After binding to a cluster, both resource groups and shared resources can go to the Workbench to create namespaces, which will be automatically bound to the workspace.
