Cloud computing features:

1. Virtualization Technology

It must be emphasized that virtualization breaks through the boundaries of time and space and is the most significant feature of cloud computing. Virtualization technology includes application virtualization and resource virtualization. As we all know, there is no spatial connection between the physical platform and the application deployment environment. It is through the virtual platform that data backup, migration and expansion are completed for corresponding terminal operations.

2. Dynamic scalability

Cloud computing has efficient computing capabilities. Adding cloud computing functions to the original server can rapidly increase the computing speed and ultimately achieve dynamic expansion of virtualization. Layers serve the purpose of extending applications.

3. On-demand deployment

Computers contain many applications, program software, etc. Different applications correspond to different data resource libraries, so users need strong computing power to run different applications. The ability to deploy resources, and the cloud computing platform can quickly allocate computing capabilities and resources according to user needs.

4. High flexibility

Most IT resources, software, and hardware currently on the market support virtualization, such as storage networks, operating systems, and development software and hardware. Virtualization elements are unified and managed in the virtual pool of cloud system resources. It can be seen that cloud computing has very strong compatibility. It can not only be compatible with low-configuration machines and hardware products of different manufacturers, but also enable higher-performance computing with peripherals.

5. High reliability

Even if the server fails, it will not affect the normal operation of computing and applications. Because a single-point server fails, applications distributed on different physical servers can be restored through virtualization technology or new servers can be deployed for computing using the dynamic expansion function.

6. High cost performance

Placing resources in a virtual resource pool for unified management optimizes physical resources to a certain extent. Users no longer need expensive hosts with large storage space. Choosing relatively cheap PCs to form a cloud can reduce costs on the one hand, and on the other hand the computing performance is not inferior to that of mainframes.

7. Scalability

Users can take advantage of the rapid deployment conditions of application software to expand existing and new services they need more simply and quickly.

Cloud computing is a type of distributed computing, which refers to decomposing huge data computing processing programs into countless small programs through the network "cloud", and then processing them through a system composed of multiple servers And analyze these small programs to get the results and return them to the user. In the early days of cloud computing, to put it simply, it was simple distributed computing, solving task distribution and merging calculation results. Therefore, cloud computing is also called grid computing. Through this technology, tens of thousands of data can be processed in a very short time (a few seconds), thereby achieving powerful network services.
Function
1. On the cloud computing network platform, everyone can build and launch their own website in a few minutes, with large space, fast speed, low cost and information security. Data in the cloud can be increased infinitely. The increase in data only increases the number of servers, and the speed of data extraction by the system is not affected.
2． Information search is faster, more precise and richer. The first cloud computing network platform to create a large-scale comprehensive portal based on China's administrative divisions and covering every region in China. The number of regional portal sub-sites has reached 60,000, including 1 Chinese site, 34 provincial-level sites, and prefecture-level sites. There are 333 stations, 2,861 city and county-level stations, and 41,636 township-level stations, some of which have been established in natural villages. Stations are interconnected and shared, and information is displayed in order from the smallest administrative unit to the largest administrative unit. The regional portal is a comprehensive portal. There is only one operator for each place name, who is responsible for website operation.
3． A platform for industry entities to publish and search information. The first cloud computing network platform, 99 large-scale portals have been created according to the industry. There is only one industry portal sub-site operator in a region. It is an exclusive operation, unique and leads the role of covering the entire industry. It is an entity product management company in various industries. Those who want to have their own industry portal company or personal cloud computing platform. Each sub-site is an independent information release platform, and the released information is quickly spread through information genetic technology.
4． Yunzhong Web Business Channel is a window for government and corporate image building, product display, and online business. You can create unlimited Web sites in Yunzhong. Merchants can log in to the Web Business Platform in Yunzhong, display their image according to the characteristics of the region and industry where the merchant is located, order online shopping, publicize and recommend, and create business opportunities.
5. The first cloud computing network platform is close to people's lives, "find items online and conduct transactions offline", enabling shopping within 3 kilometers in 30 minutes.
6． Information balance. The first cloud computing network platform provides underdeveloped areas and rural areas with the same website platform as developed areas. Technically, it ensures that the information platforms in developed areas and underdeveloped areas are at the same level, solving the problem of the informatization process in developed areas in China. The gap between China and underdeveloped regions is further widening.
7． Provide opportunities and conditions for grassroots people to take charge of their own affairs. Countless sites have been opened across China, ranging from provincial sites to township and village sites, to realize the "dividing fields into households" of the Internet.
8. Provide a large number of direct or indirect employment and entrepreneurship opportunities. The first cloud computing network platform currently has more than 6 million independent website platforms. Each platform can provide at least one employment and entrepreneurship opportunity. It can also manage and apply public information resources through the platform, provide business services, and obtain profits.
