中文摘要:
      开放科学旨在促进全球科技合作以解决诸如新冠肺炎、碳中和、自然灾害等全球性问题与挑战,然而不同机构建设的开放科学云平台之间相互独立,无法实现最大化的资源共享与科研协作,因此研究云平台互联系统结构与资源共享技术方法成为开放科学领域的一个重要课题。本文针对开放科学云平台资源管理特点,提出了一种对等代理模式的云联邦系统框架(PBMFCS),设计了云联邦系统的总体架构、逻辑架构及部署模型,讨论分析了框架的系统特性及关键技术问题。在此基础上,结合“全球开放科学云”项目需求设计实现了一个可提供基础设施服务(IaaS)层联邦云服务的原型系统,初步验证了对等代理模式云联邦系统框架的可行性与有效性,为“中国科技云”(CSTCloud)与“全球开放科学云”(GOSC)项目的未来建设与发展提供了技术参考。
英文摘要:
      The aim of Open Science is to promote international cooperation to solve global problems and challenges such as COVID-19, carbon neutrality, and natural disasters. However,scientists cannot made the most of scientific resources because of the independence between Open Science cloud platforms built by various institutes. Therefore, research on cloud platform interconnect system architecture and resource sharing methods has become an important subject in the Open Science field. This paper proposes a P2P broker model based federated cloud system (PBMFCS) based on the resource management and sharing characteristics of Open Science cloud platforms, designs the overall architecture, logical architecture and deployment model of the federated cloud system, discusses and analyzes the key technologies and methods of PBMFCS. Then, a cloud federation prototype system is designed and implemented to provide the infrastructure as a service (IaaS) level federated services, which proves the feasibility and effectiveness of PBMFCS, and provides a reference for the future construction and development of China Science and Technology Cloud (CSTCloud) and Global Open Science Cloud (GOSC) project.
