云计算:体系架构与关键技术

Cloud computing:architecture and key technologies

系统地分析和总结云计算的研究现状,划分云计算体系架构为核心服务、服务管理、用户访问接口等3个层次。围绕低成本、高可靠、高可用、规模可伸缩等研究目标,深入全面地介绍了云计算的关键技术及最新研究进展。在云计算基础设施方面,介绍了云计算数据中心设计与管理及资源虚拟化技术;在大规模数据处理方面,分析了海量数据处理平台及其资源管理与调度技术;在云计算服务保障方面,讨论了服务质量保证和安全与隐私保护技术。针对新型的云计算应用和云计算存在的局限性,又探讨并展望了今后的研究方向。最后,介绍了东南大学云计算平台以及云计算研究与应用方面的相关成果。

Based on the analysis and summary of the previous work,the cloud computing framework can be divided into three layers：core cloud services,cloud service management and user access interface.To realize low-cost,reliable,available and scalable cloud services,the up-to-date key technologies and research progresses of the three layers within the cloud framework are reviewed intensively and extensively.Regarding cloud infrastructure,the strategies for data cen-ter design and management are introduced together with the virtualization technology.In respect of large-scale data proc-essing,several platforms and their resource management and task scheduling mechanisms are investigated extensively.With regard to cloud service quality,both QoS guarantee and security/privacy protection are discussed in depth.The prospects for future research are further explored based on the new application models and limitations of cloud comput-ing.Finally,the cloud computing platform and research work of Southeast University are introduced.
