With the rapid growth of data centers, thousands of large data centers with lots of computing nodes are established. In order to user satisfaction, Assurance of QoS is important in CDCs. Also, many of the current research studies have not considered multi-metric for assurance of QoS. In this paper, we categorize QoS through previous work and build the migration scaling scheme for QoS in CDCs with considering multi-metric. And then from evaluation result, we prove that our proposed method is able to efficiently manage the resource and grantee QoS.
