“…Some of this work does not minimize energy [15,30,33] or it applies to a model different than ours (VM migration [35,36], knowledge of future load [31,36], feasibility of allocation [13], multilevel architecture [32,35,27], interconnected VMs [14], etc.). On the other hand, some of the experimental work where minimization of energy is evaluated focus on a more restrictive cost function [39,27,40].…”
