什么是云计算？ [英] What is Cloud computing?

问题描述

有人可以用简单的话说明云计算的工作原理吗？
我已阅读维基百科文章，但仍然不确定我了解如何云

b 基本上你的程序需要的所有资源都在互联网上的某处。您通过定义的服务合同与他们互动; SOAP，REST，POX或者什么，以后发生什么，取决于服务提供商。

例如，如果您想要存储文件，您可以可以选择使用Amazon的S3云系统。您连接到服务并上传文件;你不知道或不在乎文件存储的位置，只是该服务的入口点的位置。

如果你有一个应用程序，那么它也可以运行在云中，假设它是合适的。例如，Live Mesh是一个虚拟机，您可以在本地和云中对其进行编码和运行软件，因此您的用户只需访问URI并找到您的程序，您就不必关心它在哪里在云端。

Could anybody explain in plain words how Cloud computing works? I have read the Wikipedia article, but still not sure that I understand how cloud actually works.

解决方案

Aside from the latest marketing term?

Basically all the resources your program needs are held "somewhere" on the internet. You interact with them via a defined service contract; SOAP, REST, POX or whatever and what happens after that is up to the service provider. You don't care about how your information is stored or how the service is provided, just that it is.

If, for example, you wanted to store files, you may choose to use Amazon's S3 cloud system. You connect to the service and upload your files; you don't know or care where the files are stored, only the location of the entry point to that service.

If you have an application then it may also be ran in the cloud, assuming it's suitable. Live Mesh for example is a virtual machine which you can code against and run your software both locally and within the cloud, so your user simply goes to a URI and finds your program, you don't care where it is beyond it being available somewhere on the cloud.
