Web server plays a vital role on serving requests from clients. As Internet users grows so fast, the request number increases significantly, thus reducing the overall performance of the web server. One solution is to implement a load balancing system.In this paper, we implement load balancing with Linux Virtual Server to distribute the load to several machines within a cluster. We compared Round Robbin and Least Connection algorithm. The study reveals that load balancing using LVS-NAT can double the throughput output compared to single web server, but less significant on response time and CPU utilization. Implementing LVS-NAT using round robbin algorithm is more robust in optimizing the throughput, CPU utilization, and response time compared to least connection.

Load balancing of non-preemptive independent tasks on virtual machines (VMs) is an important aspect of task scheduling in clouds. Whenever certain VMs are overloaded and remaining VMs are under loaded with tasks for processing, the load has to be balanced to achieve optimal machine utilization. In this paper, we propose an algorithm named honey bee behavior inspired load balancing, which aims to achieve well balanced load across virtual machines for maximizing the throughput. The proposed algorithm also balances the priorities of tasks on the machines in such a way that the amount of waiting time of the tasks in the queue is minimal. We have compared the proposed algorithm with existing load balancing and scheduling algorithms. The experimental results show that the algorithm is effective when compared with existing algorithms. Our approach illustrates that there is a significant improvement in average execution time and reduction in waiting time of tasks on queue using workflowsim simulator in JAVA.
