What is cloud computing? I believe that many inexperienced people are at a loss about this, so this article summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

Definition:

Cloud computing (cloud computing) is a kind of distributed computing, which refers to the decomposition of huge data processing programs into countless Mini Program through the network "cloud", and then through the system composed of multiple servers to process and analyze these Mini Program results and return them to users. In the early days of cloud computing, to put it simply, it was simple distributed computing, solving task distribution, and merging computing 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), thus achieving a powerful network service.

At this stage, the cloud service is not only a kind of distributed computing, but also the result of the hybrid evolution and jump of computer technologies such as distributed computing, utility computing, load balancing, parallel computing, network storage, hot backup clutter and virtualization.

Features:

1. Virtualization technology.

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

2. Dynamically scalable.

Cloud computing has efficient computing power, adding cloud computing functions on the basis of the original server can rapidly improve the computing speed, and finally achieve the purpose of dynamically expanding the level of virtualization to expand the application.

3. Deploy on demand.

Computers contain many applications, program software, etc., and different applications correspond to different data resource libraries, so users running different applications need strong computing power to deploy resources. Cloud computing platform can quickly allocate computing power and resources according to the needs of users. [5]

4. High flexibility.

At present, most IT resources, software and hardware in the market support virtualization, such as storage network, operating system and development software and hardware. The virtualization elements are uniformly managed in the virtual pool of cloud system resources, which shows that cloud computing is very compatible. It can not only be compatible with low-configuration machines and hardware products of different manufacturers, but also enable peripherals to obtain higher performance computing.

If the server failure does not affect the normal operation of computing and applications. Because of the failure of a single point of server, the applications distributed on different physical servers can be restored by virtualization technology or the dynamic expansion function can be used to deploy new servers for computing.

6. High performance-to-price ratio.

Unified management of resources in the virtual resource pool optimizes physical resources to a certain extent. Users no longer need expensive hosts with large storage space, and can choose a relatively cheap PC to form a cloud. On the one hand, it reduces costs, on the other hand, computing performance is not inferior to that of mainframes.

7. Scalability.

Users can make use of the rapid deployment conditions of the application software to more easily and quickly expand the existing business and new business they need. For example, the failure of equipment in the computer cloud computing system will not be hindered for users, no matter at the computer level or in the specific application. The dynamic expansion function of computer cloud computing can be used to effectively expand other servers. In this way, we can ensure that the task is completed in an orderly manner. In the case of dynamic expansion of virtualized resources, the application can be expanded efficiently and the operation level of computer cloud computing can be improved.
