摘要:
针对云计算环境中服务消费者如何有效选择服务提供商,以及两者中出现的恶意非合作问题，提出基于动态信任的最优服务选择模型.该模型通过引入动态信任评估机制,结合最优服务选择算法，为服务消费者自动提供了最优服务提供者.在交易结束后,根据双方对本次服务完成情况的反馈,进行信任更新.仿真实验表明,该方法不但能够为众多服务消费者和服务提供者提供较优的匹配,还能有效减少两者中出现的恶意非合作情形.
Abstract:
Cloud computing provides four deployment models:public cloud,private cloud,community cloudand hybrid cloud.Generally,resources available in a private cloud are limited,thus the cloud users have torent resources from public clouds. This requirement means that cloud users will incur extra costs.More andmore enterprises choose the hybrid cloud to deploy their applications. In the hybrid cloud,in order to mini-mize the cost of using resources,it is also important to satisfy QoS for user. Therefore,this paper proposes re-sources allocation algorithm for hybrid cloud users who want to minimize the resource cost and ensure QoS sat-isfaction. The empirical results show that resources can be allocated by our algorithm in a way that satisfiesboth the user QoS while keeping operational costs low.
