一、前言云计算技术在互联网行业,从最初的少数大企业为解决具体问题而演进的离散的技术,到开源社区高速发展形成完整技术生态,发展非常迅速。当前云计算已经为各大厂商的业务发展贡献着不可替代的作用同时业务发展也对云技术提出了更高的要求,业务和技术相互促进,技术、产品、方案的迭代速度越来越快。从前几年云计算进入安防行业开始,也经历着类似的发展路径,从最初的技术概念阶段,到部分基于云计 I. INTRODUCTION Cloud Computing Technology In the Internet industry, the discrete technology evolving from the first few large enterprises to solve specific problems has developed rapidly into a complete technological ecosystem with the rapid development of the open source community. At present, cloud computing has made an irreplaceable contribution to the business development of major vendors. Meanwhile, business development has put forward higher requirements on cloud technologies. Services and technologies mutually promote each other, and the iteration speed of technologies, products and solutions is getting faster and faster. Cloud computing into the security industry a few years ago, has also experienced a similar path of development, from the initial stage of the concept of technology to some based on cloud computing
