Analysis of the characteristics of the development and application of cloud computing in China

One, why is cloud computing so hot?

In fact, the application of cloud computing is much earlier than the name of this technology. As early as 1996, the government agency I worked with had started to share a payroll and welfare system with other government agencies online. The online software (database) allows a large number of government agencies to directly access the payroll and welfare data of other government agencies. By today's standards, it's a typical "SaaS". By 1996, Microsoft had yet to see the prospect of http://www.aliyun.com/zixun/aggregation/5739.html "> Internet technology, and the two founders of Google were still studying at the university, Amazon is just about to sell books Online. But in a few years, by the turn of the century, when we were picking software, it was one of the metrics to "work on browsers". In the 2001, the small company that I owned, stopped buying all the servers and the phones and other hardware used by the company's office. We put the company's core software and databases on Amazon's system, and the company's phone is in the cloud. Although there is a "switchboard", the system is in a company's "cloud". Our respective desktop phones and mobile phones are all connected by that switchboard.

But there was no concept of cloud computing in our minds at that time. The term cloud appears to be popping up. From the "Brief History" above, the concept of cloud computing is not a new technology, a new product, but a "scientific name" for the application of a whispered development. Of course, today's cloud computing fundamentals and technology structures have been vastly different from those of the year before.

To be honest, when I heard about the concept of cloud computing at a conference in 2007, I didn't pay much attention to the idea of old technology being refurbished, new bottles of old wine, and "doping" by those companies. So what is making cloud computing "back to the River", and the IT sector has been "turned upside down"?

The cost of it! The cost of

It is an interesting motivator. People who study market and product development (D&R) know that under the conditions of market economy, competition among similar products is the driving force of product development. For example, HP products compete with Dell computers. Competition makes the products of two manufacturers from quality, appearance, price to after-sales service all make good, to win customers. Cloud computing as a technology of the emergence and application, but no other similar technology as competitors.

During the 2007 and 2008, the "Evil image" of economic development in the United States and the rest of the West has been Nu Duan, and people are beginning to look for opportunities to reduce operating costs in every corner of the organization's operations. We know that with the development of it, the total social operationCosts are relatively low, but the cost of it has not come down because of its rapid growth. For example, 10 years ago to spend 1000 dollars to buy a second generation of DELLPC, today, a second generation of PC prices still around 1000 U.S. dollars, but a lot of good performance. If sharing IT resources on the internet lowers it costs, and there have been precedents before, why not develop it in this direction? In this way, the concept of cloud computing is formally boarded the "elegance."

Cloud Computing can save on IT investments, which is most obvious in reducing TCO (overall costs). This is the main motivation for American companies and government agencies to clouds. As for other advantages, such as energy saving and so on, no one is too concerned. It's like a private car: rich people drive cars, people who don't have money take buses.

to look at the technical benefits of cloud computing in terms of saving it money: From Dr, backup, to data center security, and weekday technical support, the problems that have bothered your CIO all come from the cloud's provider. SaaS, in particular, doesn't have to worry about system upgrades. These questions are more than I understand, not to repeat.

The US side predicts that if cloud computing continues to grow, it will cease to exist in 10 years. Each operation department has one or two people who know more about it. The main task of the IT directors at the first level of the CIO is to manage the accounts for each cloud. In short, cloud computing will change the structure of the entire IT department.
