基于云计算理论体系对云计算应用和实践的探索和展望

全面分析云计算理论和技术，提供一个比较系统完善的云计算概念框架。同时，简要介绍云计算在Google和Amazon的实践应用和云安全问题，使得云计算这种新兴科技进一步普及，并开辟新应用领域。所谓云计算，既是一种新的商业模式，又是互联网提供新的服务的技术核心，还是一种有别于现在计算技术的新的计算模式。其思想是将大量的网络连接的计算资源统一管理调度，构成一个资源集合，以服务于用户。云计算的出现可以说是计算科学的又一次革命。

Exploration and Prospect of Cloud Computing on Application and Practical Based on Cloud Computing Theory System

This paper attempts to make a systematic and comprehensive analysis and outlook on cloud computing theory and tech- nology, provides a relatively perfect system of cloud computing concept and framework. At the same time, the paper introduces the practical application of Google and Amazon on cloud computing briefly and the problem of cloud security, and makes this e- merging technology popular and opens up new fields of application. The so-called cloud computing is a new business model, which is a core technology of the Internet on which providing new services, or rather a difference from the present computing model, it becomes a new computing model. Its core idea is a management of the large number of computational resources which net-work connection is unified, forming a set of resources to serve the users. The emergence of cloud computing can be said as another computational science revolution.
