Dependable Deployment Method for Multiple Applications in Cloud Services Delivery Network

The mutual interference phenomenon among multiple applications delivered as services through Cloud Services Delivery Network (CSDN) influences their QoS seriously. In order to deploy multiple applications dependably and efficiently, we propose theMultipleApplicationsCo Exist (MACE) method.MACE classifies multiple applications into different types and deploys them using isolation to some extent. Meanwhile, resource static allocation, dynamic supplement and resource reserved mechanism to minimize mutual interference and maximize resource utilization are designed. AfterMACE is applied to a real large scale CSDN and evaluated through 6 month measurement, we find that the CSDN load is more balanced, the bandwidth utilization increases by about 20%, the multiple applications potential statistical multiplexing ratio decreases from 12% to 5%, and the number of complaint events affecting the dependability of CSDN services caused by multiple applications mutual interference has dropped to 0. Obviously, MACE offers a tradeoff and improvement for the dependability and efficiency goals of CSDN.
