EAGER: Unifying Abstractions for OpenCloud -- Supporting a Diverse User Community.

摘要：本项目将设计一个“云管理系统（CMS）”，该系统提供了一种统一的方式来获取和控制从计算到存储到网络，从数据中心到网络边缘的各种资源，但这样做是在多个抽象层次上进行的。该项目将创建一个数据模型（一组抽象对象、对这些对象的操作以及对象之间的关系），这些模型共同定义用户如何与底层研究云进行交互。CMS统一了底层的云资源基板，并通过这些资源的自定义投影和扩展向广泛不同类别的用户呈现。该项目将通过解决其成功的最大风险来证明CMS的可行性：定义一组抽象-以操作数据模型的形式-这两个(a)统一研究云？S多样化的硬件资源，以及(b)支持广泛不同的使用模型。这些抽象构成了CMS的核心，但是它们必须满足两个相互竞争的目标。一方面，CMS为各种各样的计算和网络资源提供统一的接口，这些资源跨越许多自主托管站点，每个站点都有自己的操作策略。另一方面，成千上万的用户希望以截然不同的方式访问系统，从只想要一组VM实例的传统云用户到想要创建新云架构的云研究人员。云计算正在迅速改变计算基础设施的面貌，并且是技术领域的主要经济驱动力。该项目将为未来云计算基础设施的设计提供信息，并为Openstack社区提供原型实现，从而使云计算行业受益。

Abstract: This project will design a "Cloud Management System (CMS)" that provides a uniform way to acquire and control a wide range of resources from compute to storage to network, and from the data center to the network edge but do so at multiple levels of abstraction. The project will create a data model (a set of abstract objects, operations on those objects, and relationships among objects) that collectively defines how users interact with the underlying research cloud. The CMS unifies the underlying cloud resource substrate and presents widely different classes of users with customized projections and extensions of those resources.The project will demonstrate the feasibility of the CMS by addressing the biggest risk to its success: defining a set of abstractions-in the form of an operational data model-that both (a) unifies the research cloud?s diverse hardware resources, and (b) supports widely different usage models. These abstractions form the heart of the CMS, but they must satisfy two competing objectives. On the one hand, the CMS provides a unified interface to a widely diverse set of compute and network resources, spanning many autonomous hosting sites, each with their own operational policies. On the other hand, thousands of users want to access the system in significantly different ways, ranging from traditional cloud users that just want a set of VM instances, to cloud researchers that want to create new cloud architectures. Cloud Computing is rapidly changing the face of computing infrastructure and is a major economic driver in the technology sector. This project will benefit the cloud computing industry by informing the design of future cloud computing infrastructure and contributing prototype implementations to the Openstack community.
