摘　　要：弹性作为云计算的关键特征,能够支持资源的快速扩展、灵活配置、动态增加和释放,使得资源充分利用,同时降低云服务提供商和用户的成本。为了检测弹性是否满足用户的服务等级协议和资源的合理配置,需要对其进行评估和测试。在分析弹性定义、实现方法和评测指标的基础上,提出弹性测试的概念,总结了目前弹性测试的相关研究,分析了弹性测试的关键技术和架构,指出弹性测试面临的挑战和问题,并给出了弹性测试的进一步研究方向。Elasticity is the key feature of cloud computing,which can support resources to elastically expand,fast configured,flexibly add and remove,and it can make full use of cloud resources and reduced the cost of cloud services providers and users.To evaluate whether elasticity meet the SLA（Service Level Agreement）requirements and make full use of cloud resources,we should evaluate and test elasticity of cloud computing.In this paper,we introduced the definition of elasticity,solutions and metrics for elasticity.Then we proposed the definition of cloud computing elasticity testing,and summarized some correlational researches of cloud computing elasticity testing.Next,we summarized its key technologies and frameworks.We also discussed some challenges and issues on testing cloud computing elasticity.Finally,we put forward the further research direction of cloud computing elasticity testing.
