1. A method for generating resource selection information, wherein the method comprises: monitoring multiple cloud resources and multiple cloud resource changes performed by multiple users on a cloud; analyzing a user request submitted by a requesting user, wherein the user request comprises cloud resource parameter information; searching for at least one similar cloud resource request based on the user request and on said monitoring; and generating an output based on said analyzing of the user request to provide to the requesting user, wherein the output comprises: at least one candidate cloud resource set; and a corresponding rationale for a proposed selection of the at least one candidate cloud resource set based on historical data associated with previous experiences of one or more additional users within a cloud context identified via said searching, wherein said corresponding rationale comprises (i) a stated resource-related reason, provided by a given one of the multiple users on the cloud separate from the requesting user, why the given user, in connection with at least one of the previous experiences, performed a given one of the multiple cloud resource changes that included a given cloud resource in the at least one candidate cloud resource set, and (ii) a determined impact, on at least computing capacity, of the given cloud resource change that included the given cloud resource in the at least one candidate cloud resource set; wherein the output is sorted according to user-configured criteria comprising robustness, scalability, and response time; wherein at least one of the steps is carried out by a computer device.
