Cloud computing

1. Introduction

Cloud 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. Therefore, the ranking of

national competitiveness will change accordingly.

2. Cloud computing definition and application

The 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

provides 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 technology

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 better 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 according 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. Advantage

By providing a large and secure data storage centers for

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, another

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, 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 reflect 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 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 most 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 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 the

world-renowned market analyst firm IDC. The research show

that cloud computing will create 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 increase

re-investment and work opportunity. 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 believe that cloud computing will reduce jobs by

mistake, the opposite, it can create a lot of jobs around the world,
