One of the key tenets of the Cloud is Elasticity, which is the ability to scale out and scale down on demand.
云的重要原则之一就是伸缩性,它可以按照客户需求提供资源。
Elasticity in a system or component of a system (I'll use software as an example, since I work with IBM WebSphere eXtreme Scale every day) implies three specific degrees of freedom
系统或系统组件中的弹性(我将以软件为例,因为我每天都与 IBM WebSphere eXtreme Scale 打交道)暗示三种特定的自由程度
Based on above results, the comparison on the return to scale and output elasticity that DEA and the parametric approach offer is presented.
并依据上述结果,比较分析了DEA方法和参数方法在生产规模报酬率和产出弹性测量方面的差异。
