1. A computer-implemented method of managing a shared pool of configurable computing resources associated with a shared pool manager, the method comprising: receiving, by the shared pool manager, a set of scaling factor values which corresponds to a workload and a set of workload resource data, wherein the set of scaling factor values comprises one or more of a transaction processing scaling-factor-value, a user access scaling-factor-value, an entity storage scaling-factor-value, a product usage scaling-factor-value, and a provider-defined scaling-factor-value, wherein the workload resource data includes a plurality of configurations, each configuration specifying a different virtual machine size and resource requirement type for the workload, and wherein the workload is to be executed by a virtual machine; analyzing the set of scaling factor values with respect to the set of workload resource data to extract patterns to determine resource requirements for the workload; dynamically determining, based upon the extracted patterns, a configuration of the plurality of configurations for configuring the virtual machine to an appropriate size with the resource requirement types for processing the workload; establishing, based upon the determined configuration, the shared pool of configurable computing resources including the virtual machine which has the appropriate size; and processing, using the virtual machine which has the appropriate size, the workload.
