【摘要】 随着对计算能力、资源利用率和资源集中化的迫切需求,云计算应运而生。云计算最终目的是共享资源和服务,因此如何有效的管理以及分配资源成为云计算的重中之重。云计算资源管理系统主要负责接受客户端任务请求,根据任务请求查找相应的资源来供客户使用,因此合理的调度资源是其核心。由于资源的使用并不是无偿的,资源使用者需要根据资源使用情况付费。因此资源调度的核心依据之一是价格,合理的资源定价策略能够保证资源调度的有效性。在经济社会的垄断市场中,不同的产品提供商之间通过竞争来获得期望的最大利润,产品价格由提供商之间的竞争决定。由于云计算与经济社会具有一定相似性,因而将垄断市场下的资源定价理论引入到云计算资源管理系统中,借由该理论来确定资源价格且实现资源提供者利益最大化需求。本文从分析现有的资源管理模型入手,引入了资源初始价格策略,解决了多个资源提供者相互竞争情况下的资源定价问题。首先制定出资源描述标准,对资源提供者提供的资源进行量化,得出具体的资源描述参数。随后考虑在多个资源提供者共存的环境下,运用古诺均衡定价策略,得出均衡资源价格。由于该价格并不能从本质上反应定价策略的有效性,因此需要借助资源的调度过程来进行说明。在传统的Min-Min任务调度算法基础上,引入了价格机制,并且在云计算仿真平台上实现了该算法。从对实验结果分析可知,定价策略确实能有效的提高资源管理效率,并且在一定程度上满足用户需求。更多还原

【Abstract】 Cloud computing appear as to the needs of resource calculate, utilization and centralization. The ultimate aim of the cloud computing is to sharing resources and services, therefore, how to manage and assign resources effectively become the most important part of cloud computing.The cloud computing resources management system is mainly in charge of accept client requests, and find the corresponding resources for them, so the core of the management is reasonable scheduler. Users fee according to the service condition because of resources are not free, therefore, the core of resource schedule is based on reasonable price. A reasonable pricing policy can ensure the effectiveness of resource deployment. In the captive market, products providers through the competition obtain the maximum profits, and then the price of goods is decided by the competition among them. Because of Cloud computing is similar with the economic social in some aspects, this paper introduce the product pricing theory to cloud computing resource management, and maximum the interests of the resources provider.This paper first analyzed the existing resources management model, and then introduced a price policy to solve the problem of how to pricing in the premise of resource providers compete among each other. Firstly, this paper worked out a resource describes standards, and then got a balance price according Cournot equilibrium strategy. But because the price cannot response the reasonable pricing, thus we need to simulate resources management process. Introduced the price mechanism based on the traditional min-min task scheduler algorithm, and the platform for the algorithm. Simulate the algorithm in the cloud computing platform. The pricing policy can improve resource management effectively, and meet users needs from the results of the experiments analysis.更多还原
