The management strategy of a data center needs access to sufficient resources in order to handle different\nrequests of applications, while minimizing the consumed energy. With regard to high and varying resource\ndemands, Virtual Machines (VM) management necessitates dynamic strategies. Dynamic management of\nVMs includes VM placement and VM migration. The management approach presented in this paper aimed\nto reduce the energy consumption and the violation of service level agreements (SLA) simultaneously in\ndata centers. The simulation results indicate that proposed approach improved the VM management 40%\ncompared to the previous single-goal approaches based on the energy consumption and SLA violation rates.
