> 中文摘要: 随着云计算技术的普及,涌现出众多不同用途、不同类型的云计算平台.为了满足遗产系统整合和动态资源扩展等需求,常常需要构造混合云来统一管理不同云平台中的计算和存储资源.然而,不同云平台的管理接口和管理机制存在差异,使得开发混合云管理系统难度大、复杂度高.提出一种基于运行时模型的混合云管理方法:首先,在云平台管理接口的基础上,构造单一云平台的运行时模型;其次,根据云平台领域知识,提出一种云平台软件体系结构的统一模型;最后,通过模型转换,实现云平台统一模型到运行时模型的映射.于是,管理程序可以建立在云平台统一模型的基础上,降低了混合云管理系统开发的难度和复杂度.另外,还实现了基于运行时模型的CloudStack和亚马逊EC2混合云管理系统,并对方法的可行性和有效性进行了验证.
Abstract:With the development of cloud computing, cloud platforms of different types and purposes are emerging. Hybrid clouds are needed to manage cross-domain computing and storage resources in a unified manner in order to satisfy management requirements such as legacy system integration and dynamic resource scaling. However, there are differences in management interfaces and mechanism between different cloud platforms, which cause great difficulties and high complexity to construction of hybrid clouds. In this paper, a runtime model based approach to managing hybrid clouds is presented. First, the manageability of cloud platforms is abstracted as runtime models based on their management interfaces. Second, a unified model of cloud software architecture is provided according to the domain knowledge of current cloud platforms. Third, the synchronization between the unified model and cloud runtime models is ensured through model transformation. Thus, all the management logic can be carried out by executing programs on the unified model, which decreases the difficulty and complexity of hybrid cloud construction. The experiment on a real-world hybrid cloud, which consists of CloudStack and Amazon EC2, demonstrates the feasibility, effectiveness and benefits of the new approach in managing hybrid clouds.
