A: Virtual Datacenter (vDC) resources that have been provisioned through VMware vCloud Director can be managed by end users via the vCloud Director agent. This agent exposes the appropriate actions an end user would require for administering their assigned resources.
Some organizations also manage vCenter resources on their own in addition to those provisioned by vCloud Director. For example, there might be some vCenter resources that you manage directly, while others you purchase from an external provider.
In these situations it can be easier to manage both types of resources beneath a single pane of glass. That unified management is possible using an add-on for vCenter Server called VMware vCloud Connector. The connector is a free download from VMware’s website.
