“云”是个大家熟悉的名词,但当它与“计算”相结合,就赋予它一个全新的充满智慧的新含义,成为了当下科学技术领域最热门的关键词。“云计算”最早是在2006年由美国亚马逊公司和谷歌公司提出来的。从技术上看,“云计算”是网格计算、分布式计算、并行计算、效用计算、网络存储、虚拟化、负载均衡等传统计算机技术和网络技术发展融合的产物,它旨在通过网络把多个成本相对较低的计算实体整合成一个具有强大计算能力的完美系统,并通过网络将这强大的计算能
“Cloud ” is a well-known term, but when it is combined with “Computing ”, it gives it a brand new new meaning full of wisdom and becomes the most popular keyword in the field of science and technology. “Cloud Computing ” was first proposed in 2006 by the United States Amazon and Google. Technically, “cloud computing” is a product of the convergence of traditional computer technologies and network technologies such as grid computing, distributed computing, parallel computing, utility computing, network storage, virtualization, and load balancing. The network integrates several relatively low-cost computing entities into one perfect system with powerful computational power and integrates this powerful computing power
