原创 花絮2 云 Cloud 云态

我们经常会网购、聊天、存储、邮件等。对我们来说，这是非常繁琐的重复的活动，对于一个服务器集群来讲，处理每个人的这些日常活动所消耗的资源微乎其微，即使一台普通的电脑都可以胜任成千上万类似的请求。但是我们估计一下，当X亿的操作同时进行时，对应的资源需要多大？想象一下，每一下上网的请求是一滴小水珠，当几亿滴小水珠汇集在一起以后，是否形成天空中美丽的云？

We often go shopping, chat, mail, and more on web. This is a very tedious and repetitive activity for us. The resources consumed to handle each of these people's daily activities are minimal for a server cluster, even a normal computer can handle thousands of requests . How much resources be need when the billions operations are carried out simultaneously? Every web request is a water droplet and when billions of drops of water come together, it forms a beautiful cloud in the sky.

分布式是云的基础，分布式的核心在于将巨大的计算能力。它是利用诸多联网计算机CPU 的闲置处理能力来解决大型计算问题的一种计算科学。分布式基础上产生了云，区别在于分布式解决的问题是大而专，云解决的问题是小而杂。

Distributed is the foundation of the cloud, and the core of the distributed is the great computing power. It is a computational science that solves large computational problems by using the idle CPU processing power of computers on the Internet. The cloud is generated on a distributed. The difference is that the problems solved by distributed are large and specialized, and the problems solved by cloud are small and mixed.

根据使用的种类，云计算还有一些细分的概念。例如，云存储是指将文件或数据存在网上，云办公是指网络端的办公系统等。

根据云计算资源的使用属性分类，公有云指的是服务于大众的云资源，私有云是服务于某指定客户的云资源。

According to the service property, cloud computing has some subdivision division. For example, storage cloud refers to the data  existence on the Internet, and office cloud refers to the office system on the network side.

According to the user of cloud computing resources, a public cloud refers to a cloud resource serving the public, and a private cloud is a cloud resource serving a specified customer.
