A system and method for unit-of-use utilization of a computing resource is described. A user obtains utilization permissions for a computing resource which are recorded in a Unit-of Use (UoU) certificate. These permissions include temporal and/or functional use constraints that are static and/or dynamic. A UoU controller employs these permissions to control access by the user to the computing resource. The unit-of-use controller receives feedback from the computing resource in the form of utilization information regarding actual usage by the user which is recorded in the UoU certificate. The computing resource may include a cloud based service, operable on one or more cloud servers. The computing resource utilization permissions are preferably part of an electronic UoU certificate. This certificate is incorporated into an email, IM or a similar message medium and electronically delivered via communications network, typically from a first, user's device to a second, user's device. |
