6. Catalog Design Example : 6.1 vCloud Public Catalog : 6.1.2 Use Case
   
6.1.2 Use Case
A public service provider would like to offer to tenants, through a public catalog, a Linux distribution preinstalled in a virtual machine.
This will allow users in any organization to deploy a Linux image in a matter of minutes instead of creating a vApp from scratch and installing the operating system themselves. This is usually a long process with no value-add for the tenants. By providing a basic pre-built operating system the provider’s customers can move quickly to adding applications.
Alternatively, the service provider could offer pre-built middleware and application stacks on top of the basic operating system. This is however beyond the scope of this example.
This example shows how to install the Ubuntu server distribution in the virtual machine to be posted in the catalog.
