Cloud computing is a new technology which uses virtual machines instead of physical machines to host, store and network different components. Load balancing is a methodology to distribute workload across multiple computers, or other resources over the network links to achieve optimal resource utilization, minimum data processing time, minimum average response time, and avoid overload. The load balancing is to be done properly to gain maximum throughput and performance of cloud. Here we have considered two load balancing algorithms Equally spread current Execution algorithm and Throttled load balancing algorithm and made performance analysis of these algorithms using cloudanalyst. In Section I we gave brief introduction about load balancing in cloud computing. In section II we made a survey of Load balancing algorithms. We explained the two dynamic load balancing algorithms in section III. In section IV we introduced a simulation tool cloud Analyst and in next section V we analyzed the performance of algorithms.
