Abstract: In order to meet service level agreements between the service provider and the service consumer in cloud computing,this paper proposed a framework with meta-level scheduling and local-level scheduling in the cloud environment．It uses multi-level feedback queue scheduling algorithm in each level．The scheduling algorithm with job prioritization is used to give more priority for deadline based and shortest jobs．Also,the meta-scheduler is designed to allocate and monitor resources．Finally,the experiments simulated show that our strategy can satisfy the consumer on response time of job and can meet the SLA.
