  We propose a novel CP-Net based composition approach to qualitatively select
an optimal set of consumers for an IaaS provider. The IaaS provider's and
consumers' qualitative preferences are captured using CP-Nets. We propose a
CP-Net composability model using the semantic congruence property of a
qualitative composition. A greedy-based and a heuristic-based consumer
selection approaches are proposed that effectively reduce the search space of
candidate consumers in the composition. Experimental results prove the
feasibility of the proposed composition approach.
