1、中文 3760 字 Cloud computing applications in life Abstract: Cloud computing in common people they did not understand, in order to let the cloud computing into thousands, so that we can know what practical application in life. Through this shows that, to let people understand what is the cloud computing
2、, and what practical purpose， that can be included in the calculation of better development in the area. Keyword:Cloud Computing,Server,Client,Application. Introduction: IT industry is always to introduce some new concept, let us dizzying. NC, grid computing, IPv6, Web2.0, SOA, SaaS. .Some, such as
3、solo, and some have changed our lives. In the grid concept was put forward nearly 10 years later, another similar improved version of its new concept of cloud computing was re-raised. Text: Nowadays, a popular website games in China and the World - “Stealing food”. From Tencent “QQ farms” to the “Fa
4、cebook farm community”； From one country Farm to the worlds Farm . People seem to look for the joy with the the Computer with internet, through this social platform in touch with people all over the world. Nowadays, China and even around the world have also a popular computing- Cloud Computing. From
5、 Google, to AMD；“Cloud Computing”from a country, to the world. Technical staff seem to find value in this area, looking for the joy of success. However, the general public is difficult to“Farm”and”Cloud Computing”linked together. The reason I think is not most peoples understanding of cloud computin
6、g, which allows people to only use, but not knowing for. In fact, the farm is using cloud computing technology and its working principle is very simple. Here can be divided into 3 steps: 1. When we click on the button”harvest”, our computer will send harvested command into the servers in cloud. 2. S
7、ervers according to your instructions which is sended, through its own processing power, overwriting the data, and save on the servers hard disk. 3. The servers will modify the data back to your computers, computers according to the data, change the display. Among our computer did not participate in
8、 the calculation of the main aspects, which have to do is to send data and receive data, that is Cloud Computing. Cloud computing is an Internet-based formula, in this way, shared resources and information to on-demand hardware and software available to computers and other equipment. Run like the wh
9、ole grid. Since cloud computing is an emerging computing technology, it will certainly be a lot of advantages. Cloud computing has four distinct characteristics: 1. First, cloud computing provides the most reliable and secure data storage center, users do not have to worry about data loss, virus att
10、ack and other problems All your data is stored in the cloud it? It has been somewhere in the cloud. And desktop computing is different from the desktop environment, hard drive crashes will destroy your all the valuable data. The cloud computer crash will not affect your data storage. Because the clo
11、ud data is automatically copied, so there will never be any loss. This also means that even if your PC crashes, all your data is still in cloud, you can still visit. In a few desktop users regularly back up their data world, cloud computing can maintain the security of data. 2. Secondly, the cloud c
12、omputing on the client devices require a minimum,using is most convenient You do not need high-performance computers to run Web-based cloud application. Because the application in the cloud rather than in their own personal computers run on traditional desktop personal computer software without the
13、required processing power or disk space. Therefore, cloud computing client computer can be cheap, with a smaller hard drive, less memory, more efficient processors. In fact, the client in this case do not even need CD or DVD drive, because the need to load software programs, and need not save any do
14、cuments. 3. Enhanced computing power This is obvious. When you connect a cloud computing system, the whole of you will have discretionary power. You are no longer limited to a single computer can do things, using thousands of computers and servers, you can perform for Supercomputing type of task. In
15、 other words, in the clouds, you may want to try than greater tasks in the desktop. 4. Unlimited storage capacity Similarly, the clouds provide almost unlimited storage capacity. Imagine your desktop or notebook computer is about to run out of storage space. And the cloud can be used in hundreds of
16、PB (100 million gigabytes) capacity compared to your computers 200GB hard drive-based so insignificant. Whether you need to save something, you have enough space. Any thing with both sides, cloud calculation of course. Apart from the four notable advantages, It also has some disadvantages 1. Stored
17、data may be unsafe Customers to make cloud computing work will reduce the degree of data security, file access is also likely to be ultra vires, and will be more dependent on the network； if hackers or criminals hacking use the cloud server, threat to other peoples information security. 2. Requires
18、sustained Internet connection If you can not connect to the Internet, then, frankly, cloud computing is impossible. Because you use the Internet to connect to your application and documentation, if you do not have Internet connection, then you can not access anything, even if the document is yours.
19、Internet connection failure means a period of time does not work, Internet access in those areas where little or instability itself, the decisive factor which may affect the use of cloud computing. When you are offline ,the cloud does not work. 3. May be slow Even in a fast Web connection on the given application,on the desktop
