  7. Abstract:
  8. The proliferation of cloud services and drastic growing of IaaS data centers,encourage providers to adopt more intelligent approaches to save more energy and as a result, save more money. Today’s novel techniques such as virtualization and live virtual machine migration, provide effective solutions to service providers to fulfill this need. However, investigate the effect of different resource management and virtual machine migration approaches in virtualized data centers, require great efforts. Therefore, in this research work, we propose a model based on Colored Petri Nets to investigate the effect of live virtual machine migration in cloud data centers. Our proposed model is able to graphically model the process of admitting web server applications, allocate physical resources, and serving incoming requests for each web server, considering live virtual machine migration technique. The model is capable of modeling the process of detection over-utilized and under-utilized servers and start the process of migration. We provide the results of power consumption of each physical machine, drop probability of incoming requests and the percentage of the SLA violation by the service provider. Our results are verified using the CloudSim simulator. These results confirm that our proposed TCPN model can appropriately model the system and evaluate its performance more efficiently than the CloudSim
