在资源扩展过程中，受基于虚拟机(VM)的物理位置影响的Web应用程序的可用性是客户和云提供商非常关心的问题。本文提出了一种新的计算模型来描述层次结构云中应用程序的可用性属性。同时，我们提出了一种可用性感知的方法来探索如何以及在哪里通过垂直和水平伸缩来分配计算资源。文中还给出了仿真环境下的部分实验结果。
The availability of Web applications influenced by Virtual Machine (VM)-based physical locations during resource scaling is a crucial concern for customers and cloud providers. In this paper, we present a novel computing model to describe availability attribute of one application in hierarchical structured cloud. Meanwhile, we propose an availability-aware approach to explore how and where to allocate computing resource via vertical and horizontal scaling. Partial experimental results in simulation environment are also presented.
