Many cloud service providers face problems due to VM migration in the clustered server. Due to over migration of VM there is a loss of power, resource, costs etc. Sometimes clusters may be overloaded, demand of the CPU performance exceeds the available capacity, so a violation of the SLAs established between the resource providers may occur. To reduce these facts decision making schema is proposed in this paper. This method will be used to decide whether to migrate the VM and to switch the cluster in sleep mode or to switch the state of cluster from sleep mode to active mode. This decision is made by analyzing the current load and future load that is predicted and displayed. In this paper all the loads are being monitored and updated in the database and displayed to the service providers for decision making.
