摘要 云计算由于其按需、便捷访问弹性公共资源池的计算模式被企业广泛采用。通过云计算,用户可以根据其应用负载快速申请或释放资源。当前,大多数云应用程序都在一个单独的云平台上运行。然而,随着云计算技术的不断成熟,多云协作问题逐渐突出:越来越多的应用程序需要跨多个云平台运行来满足最优成本效率,防止云厂商锁定,提供地理位置敏感服务等。云际计算是一项由中国多家科研机构联合发起的面向下一代云计算的研究项目,旨在解决多云协同工作和更好支持用户个性业务需求等问题。在云际计算中,虚拟专用云是一种重要的服务,被设计为用户提供基于WEB的云工作环境,包含用于满足不同用户个性需求的特定软件栈、环境配置和各种资源等。本文首先介绍云际计算,然后描述虚拟专用云的设计理念,动机实例和使能技术。

Abstract: Cloud computing has been widely adopted by enterprises because of its on-demand and elastic resource usage paradigm. Currently most cloud applications are running on one single cloud. However, more and more applications demand to run across several clouds to satisfy the requirements like best cost efficiency, avoidance of vender lock-in, and geolocation sensitive service. JointCloud computing is a new research initiated by Chinese institutes to address the computing issues concerned with multiple clouds. In JointCloud, users' diverse and dynamic requirements on cloud resources are satisfied by providing users virtual cloud (VC) for special purposes. A virtual cloud for special purposes is in essence a user's specific cloud working environment having the customized software stacks, configurations and computing resources readily available. This paper first introduces what is JointCloud computing and then describes the design rationales, motivation examples, mechanisms and enabling technologies of VC in JointCloud.
