Energy-Efficient Virtual Machine Migration Algorithm in Data Centers

Abstract The issue of data center power consumption is becoming increasingly serious. One the most effective techniques for increasing resource utilization and lowering virtual machine consolidation. This paper proposes a threshold-based energy-efficient SLA-aware algorithm migration Based on statistics analysis historical status, dynamically obtains upper CPU threshold physical servers identifies whether to perform migration, so as reduce number active hosts save energy. experimental results demonstrate that proposed has better comprehensive performance. When compared existing algorithm, our method can effectively decrease energy SLA violations.
