自2006年谷歌首次提出“云计算”这一概念以来,云计算逐渐成为信息产业的重要热点领域,其被不少企业和专家视为继个人计算机、互联网之后第三次信息技术革命的核心。针对这一技术变革,很多国家早在几年前相继推出了云的发展政策与措施,助推了该市场的发展。据IDC调查显示,近几年来全球云计算市场增长速度很快,市场平均每年增长达27%,2012年该市场规模将由2009年的160亿美元增长至420亿美元。作为一项新兴的、颠覆性的技术,云计算具有强大的计算能力、存储能力、多样化的服务以及高性价比等优点,这些特点对很多行业产生了重要的影响,如在安防行业尤其是视频监控领域,云计算的发展为其带来强大的推动力。本文将介绍一些国家在云计算方面的发展情况以及多家知名企业推出的基于云计算的VsaaS解决方案、视频服务业务、计算机辅助调度服务,并对美国执法机构关于云安全问题的几个案例作些介绍。
Since Google first proposed the concept of “cloud computing” in 2006, cloud computing has gradually become an important hot area in the information industry. It is regarded by many enterprises and experts as the third information technology revolution after the Internet core. In response to this technological change, many countries launched cloud development policies and measures several years ago one after another, which has boosted the development of this market. According to the IDC survey, the global cloud computing market has been growing rapidly in recent years with the market growing at an average annual rate of 27%. In 2012, the market size will grow from 16 billion U.S. dollars in 2009 to 42 billion U.S. dollars. As a new and disruptive technology, cloud computing has the advantages of computing power, storage capacity, diversified services and high cost performance, which have a significant impact on many industries, such as the security industry in particular video Monitoring, cloud computing has brought a strong impetus to its development. This article will introduce some countries in the development of cloud computing and a number of well-known enterprises to launch cloud computing based on VsaaS solutions, video services, computer-aided scheduling services, and the United States law enforcement agencies on cloud security issues a few cases for Some introduction.
