Google's "cloud computing" services: As long as access to the Internet, you can rest assured that the use of installed in the "cloud" function, never worry about upgrading maintenance.

IBM's internal "cloud computing" attempt: let more than 300,000 of employees use computing resources remotely without having to buy additional equipment.

Antivirus industry's "cloud security": Support users do not have to install anti-virus software on a single computer, but online with the "cloud" to antivirus, more effective and safer.

Just heard of "cloud computing", really foggy, ask a few experts, get the answer is unintelligible. Always do not like too professional explanation, because some definitions, the wording of the 聱 teeth, implied is actually the lack of ability to express, if not mysterious words. So, to the concept of "cloud computing", do not think it unfathomable, we can simply see its true face in the Yunshan.

Do you remember the diskless station? That is a long time ago the securities Business Department of the necessary facilities, the display of the computer is no hard disk workstation, will not store the calculation, will only issue service requests. As to where to request, users do not need to know and do not care, even to the "cloud" in the request, we want only market data: This is a simplified version of the "cloud computing." There is no common application in the user's computer, even the operating system, but there is a series of hardware and software in a place to provide users with services, its service capacity as large as "cloud", also in the cloud, which is "cloud computing."

"Cloud computing" is a revolutionary move, just as a diversion from a well dug water model to a water supply model. For most people, computers are complex or even unpredictable, performance improvements and software upgrades can never keep up with application requirements, so always run slowly, always virus interference, always insufficient capacity. The improvement of computer hardware performance is always a fantasy, in fact, even if the computer processing capacity of every 18 months to enhance the "Moore's Law" is only a statistical law, no one can guarantee that it is always effective, However, it is a long-standing contradiction to ensure that limited hardware elevation and unlimited application or even virus-consuming system resources. In this respect, the conventional solution has become inadequate. Therefore, in the height of the Internet for computing resources to achieve optimal allocation, can really solve this contradiction, this is the "cloud computing" the original intention.

When I was doing an education project a few years ago, Google started the "cloud" program. The plan brings a lot of surprises to Google, although not so easy to implement: On the one hand, external users use Google's internal computing resources will create security problems, on the other hand, to face hundreds or more computers to program, designers in the ideological dimension of the need for a fundamental revolution.

Google is the "cloud computing" in the field of the boss, is now not afraid of Microsoft angry, early this year they launched the "cloud computing" products-Google Apps software package, the package is basically a simplified version of Microsoft Office, but it must be used online. Microsoft Office and GoogleApps use the way is very interesting: the former to install and maintenance, the latter without installation, as long as access to the Internet, you can rest assured that the use of installed in the "cloud" function, never worry about upgrade maintenance.

IBM's internal "cloud computing" attempt has allowed more than 300,000 of employees to use computing resources remotely without having to buy additional equipment. Google's "cloud computing" service relies entirely on the Internet, while IBM focuses on internal data centers. To achieve a grander vision, IBM and Google are looking forward to merging their advantage technologies.

Microsoft does not really attach great importance to "cloud computing", but its innate advantage in this respect cannot be neglected. Because if you connect hundreds of millions of Windows users over the Internet and offer them windowslive "cloud computing" services, it will be a formidable force. In fact, Microsoft is trying to get users to switch from a normal device storage mode to a networked storage model, in order to compute Google in that area.

Antivirus industry is also in the "cloud" set near. Most people have such experience, the computer in the absence of anti-virus software, running fast, installed anti-virus software, running speed will slow down, although security has been guaranteed. In order to solve this problem, antivirus manufacturers have thrown "cloud security" concept, first rising, followed by trend technology and Symantec, announced the network security into the cloud era. Hackers and viruses are rampant, "cloud security" support users do not have to install anti-virus software on a single computer, but online with the "cloud" to antivirus, more effective and safer.

If Google's cloud vision finally becomes a reality, many of the products Microsoft currently offers are largely ineffective. Because by then the personal computer only uses one module to connect the Internet, all can solve, the operating system or office and so on application software, all will become not much significance. Imagine that if Google's conspiracy succeeds, it will consolidate a powerful platform. On this platform, all operating systems, all applications, all game movies, etc., do not have to be installed on their own hard disk, the personal computer may return to the diskless era, an account can request any service, computing resources will become public facilities, like water and electricity flow into the configuration is not necessarily high computer.
