A Systematic Review on Load Balancing Tools and Techniques in Cloud Computing

Abstract

AbstractNowadays, cloud computing attracted wide attention as it can deliver IT services and resources on a demand basis over the Internet. Load balancing is a key challenge in cloud computing. Due to the complex structure of cloud computing, it is difficult and costly to evaluate the behaviour of load balancing techniques on different cloud resources based on QoS parameters in a real cloud environment. Therefore, to overcome this situation, cloud computing tools are used for simulation to test the behaviour of load balancing techniques in the cloud system under different conditions in a repeated manner by changing various parameters. There are many tools available today such as CloudSim, WorkflowSim, CloudSim4DWf, GreenCloud, and CloudAnalyst, and every tool varies in characteristic, architecture, parameters, result assessment. So, it is very important to choose an efficient load balancing tool which fulfils required QoS requirements. This work focusses on important cloud load balancing tools and provides a comparative study on important existing as well as newly proposed load balancing tools. Also, we will discuss load balancing techniques divided on the basis of three approaches.KeywordsLoad balancingCloud computing toolsSimulationHeuristicWorkflowSimCloudSim4DWfMATLABWeaveSimCloudSMEElasticSim
