A VMware vCloud® combines a vCloud Director server group with the vSphere platform. You create a vCloud Director server group by installing vCloud Director software on one or more servers, connecting the servers to a shared database, and integrating the vCloud Director server group with vSphere.

The initial configuration of vCloud Director, including database and network connection details, is established during installation. When you upgrade an existing installation to a new version of vCloud Director, you update the vCloud Director software and database schema, leaving the existing relationships between servers, the database, and vSphere in place.
