Many Cloud providers want to create a reseller model so that the reseller can provide services on the Cloud platform to their own customers. Abiquo provides this capability through Administration Scopes (introduced in V2.2).
Administration Scopes allow you to create a user who can manage a group of Enterprises (defined by the Scope). A reseller would manage a group of Enterprises who would in turn be his customers.
