4. Resource Group Architecture
A resource group is a set of resources dedicated to end-user workloads and managed by a single vCenter Server. vCloud Director manages the resources of all attached resource group vCenter Server instances. All provisioning tasks are initiated through vCloud Director and are passed down to the appropriate vCenter Server instance.
Figure 6. vCloud Resource Groups
 
Provisioning resources in standardized groupings provides a consistent approach for scaling vCloud environments. A separate vCenter Server instance is recommended to manage Cloud Resource Groups. At a minimum, place all vCloud resource workloads in a separate cluster if you are using a single vCenter Server to manage both management components and Cloud Resource Groups.
CautionDo not make changes to resource group objects using the vSphere Client. Changing the state of vCloud Director-created objects using the vSphere Client can cause unpredictable side effects because these objects are owned by vCloud Director.
