An Energy-Aware Combinatorial Virtual Machine Allocation and Placement Model for Green Cloud Computing

Resource allocation is an important problem for cloud environments. This paper introduces energy-aware combinatorial auction-based model the resource in clouds. The proposed allows users of a to submit their virtual requests as bids using provided bidding language which complementarities and substitutabilities among those resources be declared. finds most profitable mutually satisfiable set winning bids, corresponding while considering placement available physical by executing optimization problem. During optimization, also takes account non-linear energy requirements based on utilization levels find with lowest cost, thus, providing solution associated formally defined formulated integer programming. Since intractable, four heuristic methods are proposed. To evaluate performance methods, several experiments conducted comprehensive test suite. results demonstrate benefits model, high-quality solutions methods.
