Cloud computing:architecture and key technologies

Abstract

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.
