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.
