Multi Objective Optimization Oriented Policy for Performance and Energy Efficient Resource Allocation in Cloud Environment

Abstract

Cloud computing is a hybrid paradigm which makes use of utility computing, high newlineperformance cluster computing and grid computing that offers various benefits newlinesuch as flexibility, expandability, little or almost no capital investment, disaster newlinerecovery, moveable work space and much more. However, due to constantly newlineincreasing number of data centers worldwide, the issue of energy consumption by newlinethese data centers has attracted attention of researchers. newlineResource allocation and resource utilization are the major criterion in which the newlineproblem of energy efficiency can be addressed. In this research, we aim to provide newlinean energy efficient resource allocation using Multi-Objective Optimization newline(MOO) technique. We propose MOO-based virtual machine (VM) allocation newlinepolicy and implement it in CloudSim simulation environment. newlineThe results are compared with the existing policies. The results depict that MOObased newlinepolicy leads to energy saving due to an efficient resource allocation, without newlinecompromising performance of data center operations. Moreover, MOO-based newlinepolicy uses weighted sum method in which coefficient is attached with each of the newlineobjectives as a user s preference to decide a priority of objective. Genetic newlinealgorithm and fuzzy logic are used to calculate the co-efficient to generate pareto newlineoptimal solutions. In our research, we use fuzzy logic to generate the random newlinevalue of objectives co-efficient. The proposed fuzzy based computing is newlineimplemented in Cloudsim. The experimental results show that the proposed newlinescheme efficiently generates a random coefficient that assigns priority by newlineconsidering characteristics of host. Further, it demonstrates that the generated newlineweights give pareto optimum solutions that point to strict pareto curve leading to newlineexploration of more optimal solutions in MOO. newline
