From the PC to the phone to detail the cloud you've used

Cloud computing is subtly changing the way people get data and store data. For example, we are using Google search, icloud, and a variety of network disk services. The user finally sees is the operation interface, the actual use experience--fast, the operation is convenient, the humanized design, is the user most concerned question.

How does cloud computing change the user experience? From the origin of the cloud.

The traditional explanation begins with the cloud structure: SaaS, PaaS, IaaS, and it is possible for most of the unprofessional it practitioners to start cutting web pages.

In fact, the cloud is not so obscure, cloud of the prototype is Google's engineers in order to save costs at the same time to improve computer computing speed, with PC and supermarket bought the server saved out.

A simple analogy, a computing task, take a calculator to press, it may take 100 days. But if the task is divided into 100 parts, there are 100 calculator respectively press, calculate and then combine the results, one day can be completed. So cloud computing was born. Only when placed on the server and the Internet, these blocks and operations will be automatically completed by the software algorithm.

Reflected in the user experience, search, upload download files, cloud storage speed will be faster. Users search a keyword in Google's search engine, all need thousands of servers for millions or even billions of operations, and then to the user to present the required information. Without cloud computing, the search engine you see may not be what it is today.

Using a calculator to perform a task, the task cannot continue if the battery is not powered up or is down. But if you have 100 calculators, and when something goes wrong with some calculators, its tasks can be handed to other calculators to continue. The flexible computation ability call can guarantee the game factory or the electric trader to lose several machines, the net swims, the on-line shopping can continue to play still.

With so many calculators, how does cloud computing help companies save their IT costs?

Simply put, cloud computing can allow companies with light assets to buy servers, hire operational personnel, and rent cloud services over the Internet. General physical server memory usage only 20%-25%,70% more than the computing power of most of the time idle, the use of cloud services in accordance with the actual use (there may be time, flow, bandwidth comprehensive billing method) to pay the amount of money. Hardware costs and human expenditures are greatly reduced.

From the user's point of view, the century interconnection Dr Li Zhijian that the cloud can be divided into two categories: life Cloud and work cloud. Take now everybody knows the IT giant example, the apple is the typical life cloud, the user can through the terminal to the audio-visual material, the address Book and so on backup to the icloud, and then through any Apple device at any time synchronization, at any time access. Many of the map services and Life Search services we use now are backed by clouds. Working clouds such as Microsoft's evolving office365, the ideal state of full cloud can be achieved by writing a Word document on the home PC, saving it to the cloud and then going to the company with a laptop to open up on the cloud to continue to operate, on the way home with a smartphone to open check the document for typos.

Unlimited synchronization and backup, this is the cloud to the user benefits.

Century internet Dr Li Zhijian, in an interview with a Chinese journalist, presented his own view of the "pervasive age" of cloud computing: The future terminals will become thinner, the display with high-speed small core processor, connected to the Internet can be used. When terminals and clouds are cheap and simple enough to be acceptable to the public, the "pervasive age" of cloud computing will come true.
