Cloud manufacturing, a service oriented, customer centric, demand driven manufacturing model isexplored in both its possible future and current states. A unique strategic vision for the field is docu-mented, and the current state of technology is presented from both industry and academic viewpoints.Key commercial implementations are presented, along with the state of research in fields critical toenablement of cloud manufacturing, including but not limited to automation, industrial control systems,service composition, flexibility, business models, and proposed implementation models and architec-tures. Comparison of the strategic vision and current state leads to suggestions for future work, includingresearch in the areas of high speed, long distance industrial control systems, flexibility enablement,business models, cloud computing applications in manufacturing, and prominent implementation archi-tectures
