摘要: 针对云计算环境下云程序的弹性结构进行研究,结合Anytime算法、弹性计价模型和软件即服务层中的SLA计费架构,将总业务费用分为接入费用、使用费用和补偿费用进行计算,设计基于图像小波变换的弹性结构程序,给出程序的执行步骤和状态转换图。分析结果表明,该弹性结构程序能对程序迭代次数进行控制,较好满足用户需求。

Abstract: This paper researches the elastic structure of the cloud program in the cloud computing environment. It combines the Anytime algorithm, an elastic billing model and a Service Level Agreement(SLA) framework in Software as a Service(SaaS), implements an elastic structure cloud program which is based on the wavelet algorithm and presents the working process and state transition diagram. Analysis result shows that the elastic structure program can control program iterative times according to user demand, better satisfy the needs of clients.

Key words: cloud computing, Anytime algorithm, elastic program, cloud program, Service Level Agreement(SLA)
