A key concern in utility computing is managing capacity so that application service providers (ASPs) and computing utilities (CUs) operate in a cost effective way. To this end, we propose a framework for applying inventory control to capacity management for utility computing. The framework consists of: conceptual foundations (e.g., establishing connections between concepts in utility computing and those in inventory control); problem formulations (e.g., what factors should be considered and how they affect computational complexity); and quality of service (QoS) forecasting, which is predicting the future effect on QoS of ASP and CU actions taken in the current period (a critical consideration in searching the space of possible solutions).
