With holiday approaching, are you going to have a journey? Then how are you going to tell your friends about your travelling plan?

Call them? You are out of fashion!

Today what you need to do is to login to Google Docs with your Google account number, create a new document, write down your plan and send this URL to your friends. Then they can request the URL and read your plan. And no matter how many of your friends are sharing the plan, they can edit the document together with you. What’s more, you can upload the scenery and your feelings in your journey instantly to share your happiness with everyone.

If you are gone on this experience of editing documents, well then, you are enjoying a new network application pattern – Cloud Computing.

What is cloud computing?

Cloud computing is a new commercial computational model. It makes use of transmission capability of the high-speed broadband network to transfer the process of data processing from personal computer to computer groups on the net. These computers are ordinary industry standard servers which managed by a large-scale DPC (data processing center). The DPC distribute computing capability according to the clients’ need and eventually brings ab out the same efficiency with a super computer. (From Chinabyte)

Of course, we can understand it in a nonprofessional way: cloud computing is a computing model based on high-speed internet. In the remote data center, thousands of computers and servers are c onnected as a “computer cloud” (a romantic analogy). Individual users connect to the data center with terminal units as of desktops, laptops, mobile phones and PDAs to request the “cloud” to process data in accordance with

their needs.

Cloud computing is referred as the next technological revolution as it will bring us fundamental changes in our business model and working way. Thomas Watson, founder of IBM, said that the world will then need five computers in all. And Bill Gates claimed in a speech that individual users will need only 640K RAM (Random access memory).

You must have had such experiences: you upload photos and videos to a website to share with friends; you have a mail box of which the capacity is dynamically changing in accordance with your needs; you store contact information of schoolmates on a website instead of an address book… You know what I am talking about: personal homepage of Tencent Traveler –Q-zone, video sharing websites and , Gmail, address list services. These are all manifestations of online storing and sharing functions of cloud computing. There is a proper analogy: the function of data storing is just like saving money in banks. Just like our saving money in banks that are safer instead of purchasing a safe box to store it, we store our data in the cloud servers instead of a big hard disk.

Of course, the outstanding features of cloud computing are its mighty computing capability, extra-low hardware requirements and low service charge which will be explained in detail in the following sections.

Is cloud computing remote from us?

To most people, cloud computing is an unfamiliar and even mystic concept. In fact, we are unconsciously enjoying the convenience brought by cloud computing.

We are using IME (input method editor) every day. SCIM (smart common imputing method) allow us to put aside Zhi Neng ABC (an early IME which can’t intelligently get phrases of Chinese or sentences that users input). While today with large IME firms’ joining in the contending for the market of “cloud inputting”, SCIM will be much “smarter”. With the mighty computing power of service providers’
