## Vcloud API
|
||
|
|
|
||
|
|
Some useful links to get started on the vCloud API:

## Terminology
|
||
|
|
|
||
|
|
- Organization: An Organization is the fundamental vCloud Director grouping
|
||
|
|
that contains users, the vApps that they create, and the resources the vApps
|
||
|
|
use. It is a top-level container in a cloud that contains one or more
|
||
|
|
Organization Virtual Data Centers (Org vDCs) and Catalog entities. It owns
|
||
|
|
all the virtual resources for a cloud instance and can have many Org vDCs.[1]
|
||
|
|
|
||
|
|
- vApp: VMware vApp is a format for packaging and managing applications. A vApp
|
||
|
|
can contain multiple virtual machines.[2]
|
||
|
|
|
||
|
|
- VM: A virtualized personal computer environment in which a guest
|
||
|
|
operating system and associated application software can run. Multiple virtual
|
||
|
|
machines can operate on the same managed host machine concurrently.[3]
|
||
|
|
|
||
|
|
- Catalogs & Catalog-Items: Catalog is used in organizations for storing content.
|
||
|
|
Example: base images. Each item stored in catalog is referred as catalog item.
|
||
|
|
|
||
|
|
- vDC: Virtual Data Center. These are of two kinds provider vDCs (accessible to
|
||
|
|
multiple organizations), and organization vDCs (accessible only by a given
|
||
|
|
organization). In fog we refer to organization vDCs.
|
||
|
|
|
||
|
|
- Networks: You can setup various internal networks and assign various internal
|
||
|
|
ip ranges to them
|
||
|
|
|
||
|
|
## What is the difference between a virtual appliance and a virtual machine?
|
||
|
|
|
||
|
|
A virtual machine is a tightly isolated software container created to run on
|
||
|
|
virtualized platforms. It has four key virtualized resources (CPU, RAM,
|
||
|
|
Storage, and Networking); but requires the installation of an Operating System
|
||
|
|
and runs on one or more applications. A virtual appliance functions very much
|
||
|
|
like a virtual machine, possessing the four key characteristics of
|
||
|
|
compatibility, isolation, encapsulation, and hardware independence. However, a
|
||
|
|
virtual appliance contains a pre-installed, pre-configured Operating System
|
||
|
|
and an application stack optimized to provide a specific set of services.[3]
