Abstract: Emerging era in the field of Information Technology is Cloud Computing which provides services to the users over the internet. It is paid services which depends on the usage. The problem associated with this is load balancing which means to use minimum resources to improve the performance of the system.Load Balancing is the process of dynamically allocationg the work load among nodes so that not evena single node would be heavily loaded. In this paper, we have compared the performance of different load balancing algorithms on the basis of their response time.
