Cloud computing in the United States have been vigorously developed

Google CEOs describe the concept of "cloud computing," describing how users are turning to computers as the technology evolves. Users will evolve from desktop systems to models based on the central network. In the near future, all network services and applications will provide an online way. This is the basic concept and thinking of "cloud computing."

US President Barack Obama announced the implementation of a far-reaching long-term policy on cloud computing. Then in the budget document released by the U.S. government, they proposed that they should fund a large number of pilot cloud computing projects, demonstrating once again that cloud computing will play an increasingly important role in the strategies of government agencies and IT policies.

What forces prompted the U.S. government and the president to pay so much attention to such a "technological innovation" as another information technology revolution after the information revolution triggered by President Clinton's support for the INTERNET in 2000? It is also the demand of the U.S. strategy. To figure out such a problem, we must first compare the existing environment of cloud computing. Then according to the United States advocated "value analysis" to explore the interests of the.

First of all cloud computing structure is: infrastructure + operating platform + application services, cloud computing infrastructure by a large number of computing host connected by optical fiber and provide massive storage space composition.

The second layer is the operating platform, mainly program development and operating system. Let developers write order, provide services through the Internet.

The third layer is the use of consumers through the browser to run the application.

In theory, cloud computing refers to a new type of computing paradigm that relies not on a personal computer, nor as a stand-alone server, but rather as a "cloud," in which users do not need to care about their internal structure. Cloud computing brings together all the computing resources and is managed automatically by the software without human intervention. In the basic structure of cloud computing, the main part is a cloud composed of multiple servers. In order to maximize its computing power, technologies such as virtualization are usually used. The goal of cloud computing is to "use computing just as hydropower."

The author's comparative study is from the industry's publicity 'users do not need to care about their internal structure of the cloud began to explore;

The specific comparison is as follows:
◆ Amazon cloud computing platform and dawn 3000 cluster operations management system comparison;
◆ Build cloud hardware base sales and supercomputer rankings contrast, who is the biggest beneficiary of cloud;
◆ The use of software after the completion of the cloud distribution of intellectual property, who is the biggest winner;
◆ US government and China's local government to compare the use of the cloud;
◆ Deal with the game strategy of opportunity and risk of cloud computing.

Not because the biggest beneficiary of the cloud computing hardware environment is the United States, the biggest benefit of the application environment is the United States, we go to avoid cloud computing, the current desktop system, the computer giant Microsoft's "Windows" long-term monopoly of the global "operating system ", Making computer makers and consumers continue to pay, manufacturers produce computers to pay license fees, software developers to develop products in the Microsoft architecture have to pay, consumers have to keep updating the version. The rise of cloud computing, application software can be linked to the cloud, do not have to mix in the personal computer, is expected to break Microsoft's exclusive advantage. Windows operating system, though not disappear immediately, but it will no longer be so important. Therefore, cloud computing is yet another destructive innovation in the technology industry. It is also a golden opportunity for many enterprises and even countries to break through the monopoly and break through this monopoly. Therefore, cloud computing far-reaching impact on national competitiveness and our short board is the application development.

Encouraging innovation at the national level to curb the performance of local government cloud computing desire is imperative, the United States has cloud computing, but they also bear the operation and maintenance costs will also increase, so as soon as possible marketing their profit-making means. For the current application, our country is not yet urgent, moreover, our country has mastered the core technology of cloud computing, so focus on limited resources, key breakthroughs, multi-directional study of the development of cloud computing, when our application is bigger and bigger ; China's cloud computing can prop up a piece of our own cloud, get rid of doing "cloud slave" haze.
