Using vCloud API via fog
Some useful links to get started on the vCloud API:
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.
vApp: VMware vApp is a format for packaging and managing applications. A vApp can contain multiple virtual machines.
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.
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.
