A proactive multicriteria mechanism for Virtual Datacenter optimization through server consolidation is proposed. In contrast with previous works where heuristic mechanisms were designed using expert knowledge, the new proactive approach uses multiobjective evolutionary algorithms to learn fuzzy rule-based systems that determine optimal reallocation decisions according to the preferences of the datacenter operator and a prediction of the load. Experimental evaluations based on an actual IT
