| 摘要: |
| 针对云计算环境下Saa S服务可伸缩性的分析评估问题,通过分析Saa S服务伸缩性需求和特点,给出其可伸缩性定义,并且提出一种新的可伸缩性评估模型和度量指标,具体包括:资源利用率、资源生产率、收敛性。最后,基于亚马逊EC2云计算平台,对评估模型和方法进行实例验证。 |

| Abstract: |
| Cloud computing has recently emerged as a platform which provides an elasticcapability,on-demand us-age for Software as a Service (SaaS). It can dynamically adjust resource assignment based on system loads to assureSaaS quality. To address the issues for scalability analysis and evaluation of SaaS in cloud computing, this paper an-alyzes the requirements and features of scalability and defines a notion of it.Then we propose new formal models andmetrics to evaluate and analyze system scalability. Specifically, it includes resource utilization, resourceproductivity and convergence.In addition, the paper reports case study results based on Amazon's EC2 cloud tech-nology using the proposed models and metrics. |
