摘要
云计算作为一种新型的计算模式,在工业界和学术界得到了越来越广泛的应用和研究.本文首先阐述了云计算的基本概念,然后从云存储结构、编程框架、虚拟化和资源管理、安全与隐私、网络拓扑结构、能源管理等几个方面论述了当前云计算核心关键技术的发展现状,分析了其中的优势和不足,并进一步介绍了当前工业界主流的云计算平台以及学术界的开源云计算框架和实验系统.最后本文探讨了云计算进一步发展的研究问题,并展望了云计算的发展趋势.
Cloud Computing as a new computing model, has been more widely used and studied in industry and academia. This paper introduces the basic concept of the Cloud Computing, and then discusses the c state-of-the-art of key technologies and analysises its trengths and weakness from the cloud storage architecture, programming framework, virtualization and resource management, security and privacy, network topology, energy management and other aspects of cloud computing. And further information on the current mainstream of the industrial cloud system and academic open source framework and test platform of Cloud Computing. Finally, this paper discusses the main challenges of cloud computing research issues, and the cloud computing trend.
