1. A method for providing a user entity with a measurement of at least one of the value which will be realized, and the effort which will be required, if a given workload selected from one or more workloads associated with the user entity is delivered to a cloud computing environment for processing thereby, instead of being processed by a user entity processing system, said method comprising the steps of: specifying a plurality of attributes, wherein each attribute pertains to a characteristic that the user entity processing system possesses to some extent, with respect to the given workload; acquiring input data for each attribute, wherein the input data for a given attribute provides a measurement, on a prespecified scale, that represents the extent to which the user entity processing system possesses the given attribute; employing the input data for each attribute to derive respectively corresponding numerical parameter values; and using at least some of said numerical parameter values in a specified mathematical model to compute a final score, wherein said final score comprises said measurement, selectively, of said value which will be realized, or said effort which will be required.
