Load Balancing in cloud computing

Abstract-cloud computing is a structured model that defines computing services, in which data as well as resources are retrieved from cloud service provider via internet through some well formed web-based tool and application. Cloud Computing is nothing but a collection of computing resources and services pooled together and is provided to the users on pay-as-needed basis. Sharing of the group of resources may initiate a problem of availability of these resources causing a situation of deadlock. One way to avoid deadlocks is to distribute the workload of all the VMs among themselves. This is called load balancing. The goal of balancing the load of virtual machines is to reduce energy consumption and provide maximum resource utilization thereby reducing the number of job rejections. As the numbers of users are increasing on the cloud, the load balancing has become the challenge for the cloud provider. The aim of this paper is to discuss the concept of load balancing in cloud computing and how it improves and maintain the performance of cloud systems and also contains comparision of various existing static load balancers as well as conventional dynamic load balancer also
