ACCLOUD-MAN - Power Efficient Resource Allocation for Heterogeneous Clouds

In this paper we propose ACCLOUD-MAN, a novel resource manager for heterogeneous cloud data centers. In heterogeneous clouds a user request can be satisfied with more than one physical resource alternative. Resource manager must decide which resource alternative will be chosen, along with the decision of the server the request will be assigned to. ACCLOUDMAN's resource management objective is to reduce the power consumption of the cloud. Manager is modeled as an Integer Linear Problem and is implemented on MATLAB, together with a simulation platform. Simulation results show that the solution times are too long for practical applications. Dividing requests into smaller groups is suggested to improve the timings. It is seen that this method improves the timings with a penalty in decision performance.
