Internet, since the beginning of its work, has undergone many changes oneof the latest changes is how the internet cloud computing. New technologiescloud computing offers because of features all kinds of facilities to the usersas a service. Each evolution, change and novel concept in the world oftechnologies has its own problems and complications. Accordingly,benefiting from cloud computing is no exception to this rule and it haschallenged researchers and proponents in this research domain. Indeed, somemajor challenges in cloud computing are: load balancing, safety, reliability,ownership, data backup, data portability and supporting several platforms.One challenge for such matters in the field of cloud computing is loadbalancing optimization in the cloud. The so-called cloud computing,including virtualization, distributed computing, networking, software andWeb services. With respect to the ever increasing significance of loadbalancing in cloud computing the researchers in this paper intended toimprove load balancing by using a novel method. The related studies werereviewed, evaluated and compared with each other. The efficiency of theproposed method was analyzed and compared with those of other studies.The results of the present study revealed that the proposed method is betterthan other dynamic virtual machine (VM) consolidation algorithms in termsof reducing SLA (service levels agreement) violation and the amount oftransmitted data volume transmission has to present a better performancethan other methods.
