A survey on evaluating elasticity of cloud computing platform

Cloud computing becomes more and more popular for its on-demand services and pay-as-you-go model. Elasticity is the key feature of cloud computing technology, which can reduce and add resources flexibly to meet customers' need. Considering the important of elasticity of cloud computing platform, the objective of this paper is to study the evaluation elasticity of cloud computing platform. In this paper, we propose some important aspects of elasticity, such as definition and metrics. Then we address some different tools and frameworks for measuring and evaluating the elasticity of cloud computing platform. Furthermore, we discuss some open issues and challenges associated with evaluating elasticity of cloud computing platform.
