The vCloud architecture graphic shows the core and the optional components of vCloud.
Other VMware components can be added to increase capabilities or control. One example is VMware® vCenterTM ChargebackTM. vCenter Chargeback provides resource metering and reporting to facilitate resource showback/chargeback. vCenter Chargeback is composed of a vCenter Chargeback server and vCenter Chargeback data collector.
The VMware vCloud Director Web console allows administrators and operators management control of vCloud Director. The Web console and communications from the vCloud API system should connect first to a load balancer. The load balancer routes the communication to one of several vCloud Director cells.
All vCloud Director cells in the cloud share a common vCloud Director database. The vCloud Director cells should also connect to a common NFS server. The NFS server is used as a temporary storage facility for images and files that are uploaded into the vCloud Director catalog.
