云服务提供商通过正式的服务水平协议（SLA）提供对其资源的访问，并且需要良好平衡的基础设施，以便他们能够最大限度地提高他们提供的服务质量（QoS），并最大限度地减少违反SLA的数量。本文重点介绍了云计算中应用的风险评估的一个特定方面：云服务提供商和服务消费者可以在服务部署和操作期间使用的框架内的方法来评估风险。它描述了服务生命周期中进行风险评估的各个阶段，以及已设计和实现的相应风险模型。风险对建筑组件的影响，特别强调在服务操作的整体管理支持，也被描述。风险评估是有效的，通过实施的实验评估，并已集成在云计算工具包。
Cloud service providers offer access to their resources through formal service level agreements (SLA), and need well-balanced infrastructures so that they can maximise the quality of service (QoS) they offer and minimise the number of SLA violations. This paper focuses on a specific aspect of risk assessment as applied in cloud computing: methods within a framework that can be used by cloud service providers and service consumers to assess risk during service deployment and operation. It describes the various stages in the service lifecycle whereas risk assessment takes place, and the corresponding risk models that have been designed and implemented. The impact of risk on architectural components, with special emphasis on holistic management support at service operation, is also described. The risk assessor is shown to be effective through the experimental evaluation of the implementation, and is already integrated in a cloud computing toolkit.
