碩士 === 輔仁大學 === 資訊工程學系碩士班 === 102 === This thesis investigates the data-aware virtual machine (VM) migration in a cloud data center. We utilize the network topology structure of the cloud data center to design a median-based VM migration scheme. By moving the VM to reduce the average data access time of an application, the SLA requirement of the application can be satisfied. It is very possible that multiple VM may be migrated concurrently. This will introduce the physical machine contention problem to result in some VMs not to be migrated. We applies the bipartite graph modelling to migrate VMs as many as possible and minimize the total migration cost. Finally, we perform simulation experiments to demonstrate the effectiveness of the proposed scheme.
