1、Cloud computing1. IntroductionCloud computing is known as the most anticipated technological revolution over the entire world, and the reason why cloud computing has brought widespread attention is that it not only represent a new technology appeared, but also lead to the entire industry to change.

2、Therefore, the ranking of national competitiveness will change accordingly.2. Cloud computing definition and applicationThe concept of cloud computing is put forward by Google, which is a beautiful network applications mode. Based on increasing in Internet-related services and delivery models, it pr

3、ovides dynamic, easy to expand and virtualized resources usually through the Internet. This service can be related to IT, software and Internet; other services can be supported too. It means that computing power can be circulation as a commodity. As we expect, more and more enterprise use this new t

4、echnology into the practical application, such as webmail, Gmail and apple store use it for computing and storage. With the technology development, cloud computing has given full play to it roles, Industry, Newcomers and Media buy computer technology to make network cheaper, faster, convenient and b

5、etter control.Cloud computing is used in the distributed computers by computing, rather than the local computer or remote server, the operation of the enterprise data center and the Internet are more similar. This process allows companies to be able to switch resources to the urgent application acco

6、rding to computer and storage systems demand access. This means that the computing power can be negotiable, like water and electricity, access convenient and low-cost. The biggest difference is that it is transmitted via the Internet.3. AdvantageBy providing a large and secure data storage centers f

7、or cloud computing, users do not have to worry about their own data which be lost for some reason or destroyed by computer virus invasion, such as some data stored in the hard disk data will be lost by the computer damaged and virus invasion, so that users cannot access the data and recover data, an

8、other disadvantage may also appear when other people use your computer steal the user's computer, such as personal confidential information and business data loss. “Gate of blue photos " is a typical insecure example. If user uploads the photos through the Interne into data storage center,

9、it may have less chance to access personal confidential information. And with cloud computing development, for the user, these services are free of charge, for the future,advanced technology will certainly become a cash cow for merchants, and for the country, the computing power is also able to refl

10、ect a country technological level and the level of overall national strength.As the user data stored in the cloud storage center, can reduce customer demand for the hardware level, coupled with cloud computing extremely powerful computing capability, it can enable users to call data more convenient

11、and quick if can add the high-speed networks. Users no longer need replace the computer caused by having no enough hard disk space and CPU computing power. Otherwise, users only surf the Internet to access cloud storage center and then easily access the data.As powerful data storage centers, the mos

12、t wonderful features is sharing data. No matter computer data or a variety of communication devices such as mobile phones and PDA. When some damaged appeared in your phone, lost or replaced in order to chase the trend of the times and phone, data copy is a tedious thing. However, in another way, you

13、 can solve the entire problem through cloud storage center.Cloud computing services will create more millions of jobs. On March 6, a news show that show that Microsoft statement a commissioned research conducted by theworld-renowned market analyst firm IDC. The research show that cloud computing wil

14、lcreate nearly 14 million new jobs worldwide in 2015. And also predicted that it can stimulate IT innovation and brought the new revenue which can reach about $ 1.1 trillion, coupled with cloud computing efficiency substantially promote, the organization will increasere-investment and work opportuni

15、ty. IDC chief research officer , as senior vice president, John F. Gantz said: "For most organizations, there is no doubt that cloud computing will significantly enhance the return on investment and flexibility, reduce investment costs, and bring revenue growth multiplied as well, we usually be

16、lieve that cloud computing will reduce jobs by mistake, the opposite, it can create a lot of jobs around the world, no matter emerging market, small cities and small businesses will increase employment opportunities and get benefit from cloud computing. "14. DisadvantageWith large storage cente

17、r, cloud computing strongly urges powerful hardware conditions and safety measures, which including a large storage space and powerful computingcapabilities. As today's scientific and technological rapid develop, user increased, hardware capabilities become one of the necessary condition for dev

18、elopment, moreover, the cloud should be kept to enhance their computing power and storage space, and endless. Security measures also include two aspects; firstly, it is necessary to ensure that user data not damaged, lost, and stolen by others, which requires a strong IT team to full range of mainte

19、nance and strict access management strategies. Some information has been confirmed, the existingcloud computing service provider still cannot guarantee no similar problem occurs. For users, this is a very serious problem. Another security issue is a natural or unnatural disaster, also can cause the

20、storage center damaged, can cause users cannot access.Cloud computing services are available via the Internet, therefore, user usually have high demands for network access speed, although domestic access speeds improve fast, but compared with LAN, it will appear delays, incomparable, In addition, no

21、 network, the user will not be able to access cloud services.The rapid rise of Cloud technology, in another perspective, also restricts the speed of 1 Reference1development, which also lead to lower demand for high-end devices. It is the basic reason why can restrict terminal development. Customer n

22、eeds, determine the business requirements for products, if customers reduce the terminal's hardware and software requirements, the business will be greatly reduced the degree of product development and restricted the pace of the terminal technology development.5. Cloud computing development in c

23、hinaIn China, Cloud computing services have been in a state of rapid development. Looking at the cloud computing industry, government accounted for a major position, and in the market they have also been given the affirmation of the cloud computing. The cloudcomputing services major support for gove

24、rnment agencies and enterprises, therefore, the personal cloud computing services in China is a potential big cake and wait for people enjoying. However because of the domestic personal network speed upgrade too slow, and relevant government network supervision, the development of personal cloud com

25、puting services will have more difficult. Due to excessive speculation in the international aspects, in our country, a lot of companies want to get some benefit from the rapid development of technology, exploit cloud computing services projects and promote enterprise development. My personal view is

26、 that enterprises should do some preparation, judge its good or bad and prospects, as well as estimate the strength of the company and do their best. Through access to information discovery, cloud computing as a technology trend has been got the world's attention, but look at the forefront of fo

27、reign enterprise closely, we can easily find almost no companies start the business rely on cloud computing; cloud computing applications and related research are also mostly implement by those large enterprise with more funds. As the prospects for development, for the enterprise, profit is the most

28、 critical issues.Although cloud computing has been integrated into our lives, but the domesticdevelopment of cloud computing is still confronted with many problems, such as lack of user awareness, migration risk, lack of standards, user locks, security and data privacy, safety, standards, data priva

29、cy has become a topic of which we are most concerned. Nowadays, people still lack of comprehensive, systematic cognitive of Cloud computing, part of them just imitate completely others and foreign experience, ignoring the specific conditions in our country, resulting in spending much money, but fail

30、ed to alleviate the complex IT issues. In the original data center, hardware is relatively independent, but migrates to cloud computing data center, systematic assessment and scientific analysis must be essential. Otherwise it may lead to the hardware platform not achieve the proper effect and even

31、the collapse of the application system. Cloud computing products is quite diversity, but the birth of the cloud standard is extremely difficult, the major manufacturers just have their own standards, the Government is also involved, both of them are striving to be able to dominate the major position

32、, so more efforts are still needed. The other faced challenge is how to provide users legitimate services is also very important, except the risks in the systems. Compared with traditional data centers, it cloud provided more services diversity, which also bring more difficult to control. Therefore,

33、 analyze the needs of users, reasonable, enforceable service level agreements (SLAs provided will help users establish confidence in cloud computing services in a large extent. Security problems can be said that a key factor in cloud computinglanding. Amazon failure made people deep in thought, whic

34、h is just one factor of the security. The other security risks include user privacy protection, data sovereignty, disaster recovery, and even illegal interests caused by some hackers. In the era of cloud computing, there will be more user privacy data placed in the clouds, more data, and more value.

35、 Most importantly, lack of users trust will lead to cloud computing landing.Although the development road is very far away, but the Government has been giving support and encouragement. In 2012 Cloud Computing Industry Development Forum was successfully held, which is strong evidence. At the meeting

36、, as a CCID Consulting, cloud industry observers, as well as excellence forerunner of the cloud computing industry,Microsoft, with their co-operation, complete the first "China Cloud economic development Report”, which shows that in-depth interpretation the content of cloud formation and specif

37、y the key factor of economic development in the cloud. The result obtained based on the long-term observation and in-depth research on cloud computing industry. In addition, the participants share their own point about industry environment, market situation, technology development, application service elements and so on; they also can come up with any question about the cloud computing, expects will do their best to give analysis and authoritative view.26.
