Abstract: Aming at the current resource scheduling using the static load balancing strategy in cloud computing environment could easily lead to the waste of resources,the paper presents the Double Threshold(DT) of scheduling strategy based on virtual machine live migration.The strategy will compare the current load conditions with double threshold values in which is overloading or too light loading,and choose the virtual machine with lower energy consumption and between with the two values to migrate the destination node.Experimental results show that the strategy can reduce the migration times and the energy consumption of virtual machine migration,so as to achieve load balancing and meet service level agreement(SLA) requirements.
