Performance evaluation of load balancing policies across virtual machines in a data center

Cloud computing has become one of the most significant issues in recent years. Its benefits have attracted almost every sector. Cloud computing provides software, platform for creating new applications and hardware or infrastructure as a service. A cloud service provider provides services on the basis of client´s requests. Client´s requests are processed in the virtualized data centers where a physical machine runs a number of virtual machines on it. An important issue in cloud is scheduling of virtual machines in a data center In this paper, we are going to evaluate the performance of three load balancing policies round robin, throttled and equally spread execution load, across virtual machines in a single data center. We also analyze the impact of these load balancing policies on different service broker policies.
