Dynamic load balancing in Cloud Storage

Abstract

“Cloud computing” is a term, which involves virtualization, distributed computing, networking, software and web services. A cloud consists of several elements such as clients, datacenter and distributed servers. It includes fault tolerance, high availability, scalability, flexibility, reduced overhead for users, reduced cost of ownership, on demand services etc. From few last decades, there is a rapid growth of data in cyberspace therefore cloud is becoming an important service in internet computing. Infrastructure as a Service provides on-demand virtual machines to users. In accordance with the client’s demand at a datacenter, host creates VMs which increase the load on the host. If the load of any host exceeds its capacity, then it affects their efficiency. Load balancing plays an important role in the deployment of virtual machines onto physical hosts. Resource requirement of virtual machine is hard to predict. Thus to deal with this issue, lots of load balancing methods are present. So in this paper we discuss these load balancing methods to provide overview of latest approaches in IaaS. Different load balancing methods have different parameters. So, we compared them on the basis of parameters used for their method. We have proposed our own load balancing method after comparing all available methods.
