A system, method, and computer program product for determining an optimal configuration for a computing system. For example, a method may include accessing functional requirements and resource constraint information. Functional requirements are converted into hardware requirements and functional models are generated, each of which satisfies the hardware requirements. Functional models are converted to functional utilization models, and functional utilization model values are generated for the functional utilization models. The method also may include defining a resource model for each of the functional models and converting the resource models to resource utilization models. A resource utilization model value is generated for each of the resource utilization models. A set of viable models is identified based on the values for the functional utilization models and the resource utilization models, and then a best fit model is identified based on the determined functional model value and the determined resource constraint model value.
