摘要：As we all know cloud computing is one of the fast spreading technologies for providing IT based Services to its User. We have established large-scale virtualized data-center to meet this requirement. To provide efficient and reliable services to all its user data centers consumes large amount of computation power. Due to large consumption of electrical energy has increased cost for the service provider as well as service users. Large consumption of electrical energy Couse large amount of carbon dioxide to emitted, due to this global warming is affected. We concluded that, from our studies we can reduced the power consumption by live migration of the Virtual machine (VM) by turning off idle machines. To fulfill this entire requirement we proposed a dynamic threshold based approach for CPU utilization for host at data center. This will work on dynamic and unpredictable workload to avoid unnecessary power consumption. Because of this we will achieve energy efficiency with quality of service to the user by controlling service level Agreement violation (SLA)
