Cloud? Cloud!


(Last time, I said I’d continue writing something about New Moon. However, I’ve decided to abort the plan. Most of the time, a sequel is not comparable with the original one since the interest and curiosity of the audience has been completely sucked by the original one. So, I must find something new to write about.)

You think I would write the fuzzy intangible agglomeration up in the sky? No way. What I am really going to write about is the down-to-earth technology of cloud computing. Before I came here, my father told me that IBM was negotiating a large contract with our local government to land a “cloud factory” in my hometown, the very first of its kind in China. At about the same time, a new service named document was provided by the new giant Google. It allows people to edit their documents, spreadsheets and slides online. Since then I could see an inevitable trend that all software and even platforms will be provided in the form of “cloud” in the future.

Actually, cloud is a new way of thinking in computing. The concept incorporates infrastructure as a service (IaaS), platform as a service (PaaS) and software as a service (SaaS) as well as other recent technology trends that have the common theme of reliance on the Internet for satisfying the computing needs of the users. Cloud computing services usually provide common business applications online that are accessed from a web browser, while the software and data are stored on the servers. The “cloud factory” mentioned above is a typical example of IaaS. The factory is actually a centre fully equipped with advanced computers to perform grid computing, which allows astronomical data to be analyzed and pocessed within several hours. Google’s new service is a SaaS as it functions just like the software Office provided by Microsoft.

The greatest advantages of cloud computing could be seen in the cost cut and stability. As all the services will be provided online, the capital expenditure will be hugely cut down as the consumption will be based on utility. It means there will be no upfront cost and consumers will only pay for what they have used or the time they have used. Cloud computing largely simulates the displacement of electricity generators by electricity grids early in 20th century. Moreover, the data for common users would be much safer as they are stored on servers instead of PCs, whose stability are really doubtable.

Personally, I am really looking forward to the upcoming service Gdrive of Google, which the beta has already been released. Gdrive will install a virtual drive on your PC and all the documents put in it would be uploaded to Google’s servers. Then you do not need to worry about your data since they are stored on Google’s server. It would be a huge relief for people like me who have experienced breaking-down of the operating system( which equals to the loss of all data in my computer). Though some people are concerned about the privacy problem, I believe it would be solved soon.

Oh! Come on, Gdrive.

  1. Thank you for sharing this information. However, I find it too technical. Anyway, in any new technology, people will get excited to see its potential and how it can be beneficial to mankind.
