/**
 * A cloud can contain one or more Organizations. There are two types of Organizations, hard-walled
 * and soft-walled.
 * 
 * A hard-walled Organization provides a secure environment for a single tenant of a
 * multi-tenant cloud.All resources in a hard-walled Organization are isolated from other
 * Organizations, hard- or soft-walled,in the cloud.
 * A soft-walled Organization supports access, by users who have appropriate privileges, to
 * other soft-walled Organizations in a cloud. Soft-walled Organizations have boundaries similar to
 * those that separate departments of a corporate entity. In such environments, the Organization
 * controls the resources owned by a single department. Most users are restricted to the resources
 * available in a single Organization but a few might have privileges in other Organizations, if
 * allowed by the administrators of those Organizations.
