为了制定多种业务质量要求服务的资源购买方案,通过平台服务商与基础设施服务商之间签订基于服务等级协议的资源分配协议,提出一种面向应用性能的云计算弹性资源调整方法。该方法利用自动伸缩算法,在垂直层次上对负载需求的波动进行虚拟机资源调整,以实现动态调整分配资源量来满足应用的服务级别的需求,优化云计算资源利用率。最后通过仿真验证该算法的有效性。
為瞭製定多種業務質量要求服務的資源購買方案,通過平檯服務商與基礎設施服務商之間籤訂基于服務等級協議的資源分配協議,提齣一種麵嚮應用性能的雲計算彈性資源調整方法。該方法利用自動伸縮算法,在垂直層次上對負載需求的波動進行虛擬機資源調整,以實現動態調整分配資源量來滿足應用的服務級彆的需求,優化雲計算資源利用率。最後通過倣真驗證該算法的有效性。

To make resources purchase plan of service which has a variety of service quality requirements, this paper proposes an application performance oriented-cloud computing elastic resources adjustment method through the platform as a service and infrastructure as a service to sign agreement on allocation of resources based on Service-Level Agreement. Using the automatic scaling algorithm,this method adjusts virtual machine resources of load demand in the vertical level. In order to dynamically adjust allocation of resources to meet the needs of application service level,the cloud computing resources utilization rate is optimized. Simulation results are provided to show the effectiveness of the proposed method.
