软件定义的云际计算基础理论和方法研究进展

Research Progress on the Basic Theory and Method of the Software-Defined JointCloud Computing

云计算生态中云服务提供者的独立性是天然存在的,但由此带来的单一云服务商边际效益下降、云服务用户平台锁定等痛点问题已严重制约云产业的健康发展。为解决云计算发展新时期的瓶颈性问题,云际计算作为一种前瞻性研究对象,应运而生。云际计算支持传统云各个层面(如IaaS、PaaS、SaaS、DaaS等)的各类云参与者(例如提供者、消费者、代理者、监管者等)之间以互利互惠方式进行双边或多边协作,以应对当前云计算发展所面临的重大挑战。本文首先系统介绍了国家重点研发计划项目"软件定义的云际计算基础理论和方法"的提出动机和研究价值;然后,深刻揭示了云际计算模型机理及其背后的设计哲学,进而详细阐释了3项关键支撑技术和1项综合定制技术的核心思想及所取得的研究进展;最后,紧扣云计算和大数据重点专项任务使命,从云计算和大数据两个维度对未来研究重点进行了展望。

The independence of cloud service providers in the cloud computing ecosystem exists naturally,but the resulting pain points such as the decline of marginal benefit of single cloud service providers and the lock of cloud service user platform have seriously restricted the healthy development of cloud industry.In order to solve the bottleneck problem in the new period of cloud computing development,JointCloud computing as a prospective research object came into being.JointCloud computing supports bilateral or multilateral collaboration among various cloud participants(such as providers,consumers,agents,regulators,etc.)at different levels of traditional cloud(such as IaaS,PaaS,SaaS,DaaS,etc.)in a mutually beneficial manner to meet the major challenges facing the development of cloud computing.Firstly,this paper systematically introduces the motivation and research value of the national key r&d project“Basic Theory and Method of Software-Defined Joint-Cloud Computing”.Then,the mechanism of Joint Cloud computing model and the design philosophy behind it are deeply revealed,and the key thoughts of three key supporting technologies and one comprehensive customization technology and the research progress made are expounded in detail.Finally,it looks forward to the future research from the two dimensions of cloud computing and big data.
