1. A method for monitoring use of a cloud computing environment, the method comprising: a computer determining an amount of effort for completing a task in the cloud computing environment; the computer calculating a measurement of value for completing the task based on a mathematical model the computer presenting each workload of a plurality of workloads in a graph, wherein a given workload is positioned with respect to first and second axes of the graph according to first and second final scores, respectively, of the given workload; and the computer selecting a given workload for delivery to the cloud computing environment for processing thereby only when the given workload complies with at least one of a first criterion and a second criterion, wherein the given workload complies with the first criterion when the first final score of the given workload exceeds a first pre-specified criterion value, and the given workload complies with the second criterion when the second final score of the given value is less than a second pre-specified criterion value.
