English英语译成Chinese汉语 技术/工程设计 IT（信息技术） cloud computing

In the traditional computing model, you use an application to create a document (be it a manuscript, a spreadsheet, a database, or what-have-you). Then, when you want to save the document, the application hands it off to the operating system, which maintains a copy of it in local storage as a file.

Google's model represents a radical departure. In it, the cloud is the computer, from alpha to omega. Because there are no disks or volumes for the user to maintain, there is no need for the artificial concept of "files" or a file system to store them in. Persistent storage is reduced to an abstract concept: {All that exist are applications and their associated documents. }
谷歌的模式却截然不同。在这种模式中，云计算环境自始至终是计算机。因为用户不需要维护任何磁盘或者磁盘卷，所以也就不需要“文件”或者用来保存文件的文件系统这种人工概念。持久性存储沦为一种抽象概念：凡是存在的都是应用程序及相关文档？
