云计算是计算架构的一场革命，不仅改变了计算的“地点”，还改变了“方式”（软件的生产方式以及可用于业务流程自动化的工具）。当我们从底层计算资源既稀缺又昂贵的时代过渡到相同资源既便宜又丰富的时代时，云计算就出现了。实现云架构的方法有很多种，大多数人都熟悉 Gmail 或 Facebook 等公共云服务。然而，云计算对经济的大部分影响将取决于大型企业如何实施云架构。云还准备通过新一波商品化浪潮颠覆信息技术 (IT) 行业。在计算资源稀缺的时代，针对高性能而优化的产品正在让位于利用当今廉价、丰富的计算资源的松散耦合、弹性管理的架构。
Cloud computing is a revolution in computing architecture, transforming not only the “where” (location) of computing, but also the “how” (the manner in which software is produced and the tools available for the automation of business processes). Cloud computing emerged as we transitioned from an era in which underlying computing resources were both scarce and expensive to an era in which the same resources were cheap and abundant. There are many ways to implement cloud architectures, and most people are familiar with public cloud services such as Gmail or Facebook. However, much of the impact of cloud computing on the economy will be driven by how large enterprises implement cloud architectures. Cloud is also poised to disrupt the Information Technology (IT) industry, broadly conceived, with a new wave of commoditization. Offerings optimized for high performance in an era of computing resource scarcity are giving way to loosely coupled, elastically managed architectures making use of cheap, abundant computing resources today.
