Introduction to allowed datacenters

When you first create a datacenter or public cloud region, by default only the users of the enterprise that created it will be allowed to use it. To enable other users to deploy and work with VMs, administrators must allow enterprises to access datacenters or public cloud regions. For brevity, these may be collectively called "Allowed datacenters" or "Allowed locations". For each allowed location, the enterprise will have an Apps library with their templates, and their virtual datacenters for deploying VMs.  

Allowed locations are where users can work, for example, create a virtual datacenter and deploy VMs. To administer the infrastructure of a location, the administrator must also have the location in their administration Datacenters scope list. See  Manage Scopes
