摘要
云计算是一种新型的基于Internet的计算机技术。针对云计算的定义,介绍了其发展历史,比较了现有的云计算定义,并结合其虚拟化技术、动态可扩展、按需部署、高灵活性、高可靠性、高性价比等特点,给出了综合的概念。在总结了云计算技术的7种实现形式的基础上,分析了云计算技术的现状以及发展趋势。
Cloud computing is a new Internet-based computer technology. This paper introduces the historical development of cloud computing in the narrow and broad senses. Various definitions of cloud computing are compared, and a generalized concept of cloud computing is put forward combining its features of virtualization, dynamic extensibility, deployment according to need, high flexibility, high reliability, and high cost efficiency. Following a summery of the seven forms of cloud computing technology, the present status and future trend of cloud computing technology are analyzed. The research and analysis provides a guide to the direction of computer network algorithms.
