Unit-based licensing of services may include receiving a unit-based licensing service access request message including information indicating a customer account, a requested service, requested utilization temporal data, and requested utilization spatial data. In response to receiving the unit-based licensing service access request message, availability data may be identified for the requested service. On a condition that the availability data indicates an available state corresponding to the requested service, a cardinality of assigned units based on the requested service and a cardinality of available licensing units allocated to the customer account may be determined. A response message may be output, which may include indicating that the request is granted, on a condition that the cardinality of the assigned units is within the cardinality of the available licensing units, or indicating that the request is denied, on a condition that the cardinality of the assigned units exceeds the cardinality of the available licensing units.
