Tenants in OpenStack are a way of keeping user's cloud resources separate and are also referred to as projects within Nova Network. In a tenant, there are a number of images, instances, and its own network resources assigned to it. When we create a tenant, we assign it its own VLAN with its own private and public ranges. For example, we may wish to create a development tenancy that is separate from the performance testing tenancy and live tenancies.
