vCloud Catalogs

Catalogs contain references to virtual systems and media images. A catalog can be shared to make it visible to
other members of an organization, and can be published to make it visible to other organizations. A vCloud
system administrator specifies which organizations can publish catalogs, and an organization administrator
controls access to catalogs by organization members.

vCloud Tasks

Long‐running operations initiated by members of an organization create tasks, which are kept on the
organization's tasks list.

Virtual Systems and Media Images in a vCloud

Virtual systems and media images are stored in a vDC and can be included in a catalog. Media images are
stored in their native representation (ISO or floppy). Virtual systems are stored as templates, using an open
standard format (OVF 1.0). These templates can be retrieved from catalogs and transformed into virtual
systems, called vApps, through a process called instantiation, which binds a template's abstract resource
requirements to resources available in a vDC. A vApp contains one or more individual virtual machines (Vm
elements), along with parameters that define operational details such as:

How the contained virtual machines are connected to each other and to external networks.

The order in which individual virtual machines are powered on or off.

End‐user license agreement terms for each virtual machine.

Deployment lease terms (typically inherited from the containing organization) that constrain the vApp's
consumption of vDC resources

Access control information specifying which users and groups can perform operations such as deploy,
power on, modify, and suspend on the vApp and the virtual machines it contains.
