| 中文摘要: |
| 云计算作为全新的计算模式，将数据中心的资源包括计算、存储等基础设施资源通过虚拟化技术以服务的形式交付给用户，使得用户可以通过互联网按需访问云内计算资源来运行应用.为面向用户提供更好的服务，分布式云跨区域联合多个云站点，创建巨大的资源池，同时利用地理分布优势改善服务质量.近年来，分布式云的研究逐渐成为学术界和工业界的热点.围绕分布式云系统中研究的基本问题，介绍了国际、国内的研究现状，包括分布式云系统的架构设计、资源调度与性能优化策略和云安全方案等，并展望分布式云的发展趋势. |
| 英文摘要: |
| Cloud computing as a new computing model, provides computing and storage services to users by the virtualization technology. Users then can request and access elastic cloud resources on demand to run their applications via the Internet. Recently geo-distributed cloud has been a hot research topic in both academia and industry. It federates multiple cloud sites to maintain huge and distributed virtual resources, so as to provide better services for users. Based on fundamental research problems in geo-distributed cloud systems, this acticle describes the international and domestic research progress of this area, including architecture design, resource scheduling schemes, and security mechanisms. It also points out some of the research trends in the field. |
