Terms Used in this Paper

Definitions for key concepts in vCloud Director 1.0 follow. These terms have been used extensively in this white

paper. For more information, refer to the

vCloud API Programming Guide

[7].

•

vCloud Organization – A vCloud organization is a unit of administration for a collection of users, groups, and

computing resources. Users authenticate at the organization level, supplying credentials established by an

organization administrator when the user was created or imported.

•

vCloud Virtual Datacenters – A vCloud virtual datacenter (vDC) is an allocation mechanism for resources

such as networks, storage, CPU, and memory. In a vDC, computing resources are fully virtualized, and can be

allocated based on demand, service level requirements, or a combination of the two.

There are two kinds of vDCs:

– Provider vDCs – These vDCs contain all the resources available from the vCloud service provider. Provider

vDCs are created and managed by vCloud system administrators.

– Organization vDCs – These vDCs provide an environment where virtual systems can be stored, deployed,

and operated. They also provide storage for virtual media, such as floppy disks and CD-ROMs.
