针对云计算研究领域对其关键特性缺少清晰和定量的测量手段的现状，提出了一项可以有助于提供一系列云计算性能基准的预备工作，即提出了一个测量云计算弹性能力的模型。云计算系统的弹性指的是其在用户请求随时发起的情况下的可扩展及可收缩性。所阐述的工作主要集中在定义物理设备使用中的弹性能力及其的测量上，该定义被用于表示云计算环境的基础特性及其与弹性相关的参数上，并且将提出的模型所采用的方法和重点列出的一些基础参数对弹性的影响作为测量依据，继而通过实验案例研究展示。实验结果显示，该模型对云计算环境的弹性可以较好地进行测量及描述。

Recently,cloud computing as the method to reduce the computing device infrastructure resource expensive and reduce the maintenance cost,has attracted many researchers attention. Cloud computing has many key characteristics,such as reliability,reusability and flexibility lease. However, these characteristics measurement are lack of a clear and quantitative standard. In this paper,a preparatory work is proposed can help to provide a series of cloud computing performance benchmark. Specifically,a measure of flexibility of cloud model is provided. Cloud computing system elasticity refers to a request initiated from a user at any time in case of extension and contraction. Elastic meaning this work focuses on the definition of the physical equipment in use,the definition is used to represent the basic characteristics of cloud computing environment parameters and elastic related. And the basic parameter method and the point of the model proposed is influenced in this paper using the list of elastic as measurement basis,and through the display of test case.
