The main aspect of any cloud application is to provide simultaneous access to number of users by reducing the cost of maintenance. This is mainly achieved by the process of implementing virtualization effectively. Virtualization is considered to be the core of cloud computing and it mainly deals with the process of creating and maintaining the virtual machines efficiently. This paper focuses on implementing an algorithm to distribute the load among virtual machines created in a data center. The algorithm mainly relies upon Least Frequently Used mechanism. Each time when a task has to be submitted to a data center for processing choice is made upon the virtual machine which has been assigned tasks least number of times. This process is mainly employed to keep the virtual machines busy in processing for most of the time. The simulation tool Cloud Analyst is used to develop and test the algorithm. An analysis also has been made on the proposed algorithm with the ones that are already in practice with the simulation tool.
