摘　　要：随着网络带宽的不断增长，通过网络访问非本地的计算服务的条件越来越成熟，于是就有了我们称作“云计算”的技术。云计算能够给用户提供可靠的、自定义的、最大化资源利用的服务，是一种崭新的分布式计算模式。随着对云计算应用的不断扩大和深入，对云计算的性能提出了更高的需求，因此，很多研究员也在努力提高对云计算的性能。文章阐述了云计算的基本概念，并在此基础上介绍了云计算领域里的数据计算与数据存储的相关技术，重点介绍了多用户隔离机制，最后预测了云计算的发展及其未来。With the continuous growth of the network bandwidth, the conditions are more mature that access non-local computing services through the network, so there is a technology what we call ＂cloud computing＂.The cloud computing is a new application model for de- centralized computing which can provide reliable, customized and maximum number of users with minimum resource.With the constantly expanding and deepening of the cloud computing applications, it asks for higher demand, therefore, many researchers also strive to improve the cloud computing performance. The article explains the basic concepts of cloud computing, and on this basis, it also introduced the technology of data computation and data storage, it has a detailed description to the multi-user isolation mechanism, and finally to predict the development of cloud computing and its future.
