Cloud computing has many definitions. What is cloud computing? There are at least 100 explanations. At this stage, it is generally accepted that the National Institute of Standards and Technology (NIST) defines cloud computing as a pay-per-use model. This model provides available, convenient and on-demand network access, and enters a configurable pool of computing resources (resources include networks, servers, storage, application software and services), which can be quickly provided through little management work or service providers.
trait
Cloud computing is to distribute computing on a large number of distributed computers instead of local computers or remote servers, and the operation of enterprise data centers will be more similar to the Internet. This enables enterprises to switch resources to required applications and access computers and storage systems as needed.
This is like changing from the old single generator mode to the centralized power supply mode of power plants. It means that computing power can also be circulated as a commodity like gas and water and electricity, which is convenient to obtain and low in cost. The biggest difference is spread through the Internet.
The recognized characteristics of cloud computing are as follows:
(1) Very large scale
"Cloud" has a considerable scale. Google cloud computing has more than 1 10,000 servers, and Amazon, IBM, Microsoft, Yahoo and other "clouds" have hundreds of thousands of servers. Enterprise private clouds generally have hundreds of servers. "Cloud" can give users unprecedented computing power.
(2) Virtualization
Cloud computing supports users to obtain application services at any place and using various terminals. The requested resources come from the "cloud" rather than a fixed tangible entity. The application runs somewhere in the cloud, but in fact, users don't need to know or worry about the specific location where the application runs. All we need is a notebook or a mobile phone, and we can achieve everything we need through network services, even such tasks as supercomputing.
(3) High reliability
"Cloud" adopts measures such as fault tolerance of multiple copies of data and isomorphic interchange of computing nodes to ensure high reliability of services. Using cloud computing is more reliable than using local computers.
(4) universality
Cloud computing is not specific to a particular application. With the support of cloud, ever-changing applications can be constructed, and the same cloud can support different applications at the same time.
(5) High scalability
The scale of the "cloud" can be dynamically expanded to meet the growing needs of applications and users.
(6) on-demand service
"Cloud" is a huge resource pool, which you can buy on demand; Clouds can be charged like tap water, electricity and gas.
(7) extremely cheap
Because the special fault-tolerant measures of "cloud" can use extremely cheap nodes to form a cloud, the automatic centralized management of "cloud" makes a large number of enterprises not have to bear the increasingly high cost of data center management, and the universality of "cloud" greatly improves the utilization rate of resources compared with the traditional system, so users can fully enjoy the low-cost advantage of "cloud", and often it takes only a few hundred yuan and a few days to complete tasks that used to take tens of thousands of yuan and months.
Cloud computing can completely change people's future lives, but at the same time, we should pay attention to environmental issues, so as to truly contribute to human progress, rather than simply upgrading technology.
(8) Potential dangers
Cloud computing services not only provide computing services, but also provide storage services. However, cloud computing services are currently monopolized by private institutions (enterprises), and they can only provide commercial credit. For government agencies and commercial organizations (especially commercial organizations with sensitive data such as banks), we should be vigilant when choosing cloud computing services. Once commercial users use cloud computing services provided by private organizations on a large scale, no matter how strong their technical advantages are, these private organizations will inevitably seize the whole society with the importance of "data (information)". For the information society, "information" is crucial. On the other hand, the data in cloud computing is confidential to users other than the data owner, but it is really not a secret to commercial organizations that provide cloud computing. All these potential dangers are important premises that commercial organizations and government agencies have to consider when choosing cloud computing services, especially those provided by foreign organizations.

What does cloud computing mean?
In a sense, cloud computing is a pay-per-use model, which provides available, convenient and on-demand network access, and can quickly provide configurable networks, servers, storage, application software and services. It can be simply understood as a dynamic server cluster. Cloud computing can be regarded as the most important general technology in this era, and its goal is to let people use computer resources like water, gas and electricity. Since its appearance, cloud computing has become more extensive and important, which will bring about fundamental changes in life, production mode and business model and become an important part of strategic information industry in various countries. In China, the cloud computing industry is developing rapidly. According to a data released by the Ministry of Industry and Information Technology, during the Twelfth Five-Year Plan period, the average annual growth rate of China's cloud computing industry exceeded 30%, reaching about 654.38+05 billion yuan by the end of 2065.438+05. At present, there is a great demand in the cloud computing market, showing an explosive trend. According to the data of CCID Consulting, the market scale of cloud services in China has exceeded 50 billion yuan in just 20 16 years. In particular, the policy advantage of developing cloud computing in China is obvious, which gives the industry a good development environment. In 20 18, the 13th Five-Year National Strategic Emerging Industry Development Plan issued by the State Council mentioned that technologies such as Internet of Things, cloud computing and artificial intelligence should be fully integrated and infiltrated into all industries, and a new generation information technology industry system with Internet of Everything, integration and innovation, intelligent collaboration, security and controllability should be built. By 2020, we will strive to achieve a systematic breakthrough in the weak links of the new generation of information technology industry, with a total output value exceeding 12 trillion yuan.

What is the specific meaning of cloud computing?
Look at your own definition: personal explanation: accessing data on a computer is a kind of cloud computing. Official explanation: Cloud computing is a mode of increasing, using and delivering related services based on the Internet, which usually involves providing dynamically scalable and often virtualized resources through the Internet. Cloud is a metaphor of network and internet. In the past, cloud was often used to represent telecommunication networks, and later it was also used to represent the abstraction of the Internet and the underlying infrastructure. In a narrow sense, cloud computing refers to the delivery and use of IT infrastructure, and refers to obtaining the required resources in an on-demand and scalable way through the network; Cloud computing in a broad sense refers to the delivery and use of services, and refers to obtaining the required services in an on-demand and extensible way through the network. The service can be related to IT and software, Internet or other services. It means that computing power can also be circulated as a commodity through the Internet.

What does "cloud computing" mean?
"Cloud computing" means that the increase, use and interaction of Internet-based related services usually involve providing dynamically expandable and often virtualized resources through the Internet. Generally speaking, cloud computing is computing through a large number of computing resources in the cloud. For example, users send instructions to service providers providing cloud computing through their own computers, perform "nuclear explosion" calculations through a large number of servers provided by service providers, and then return the results to users. Extended data:
The evolution of cloud computing: the stage of power plant mode: the power plant mode is like using the scale effect of power plants to reduce electricity prices, making it more convenient for users to use without maintaining and purchasing any power generation equipment. Utility computing stage: 196 1 year, McKinsey, the father of artificial intelligence, put forward the concept of "utility computing" at a meeting. Its core draws lessons from the power plant model, and its specific goal is to integrate the servers, storage systems and applications scattered all over the country for multiple users to enjoy, so that users can use computer resources as if they were plugging a light bulb into a lamp holder, and pay according to the usage. Grid computing stage: Grid computing studies how to divide a problem that requires huge computing power into many small parts, then distribute these parts to many low-performance computers for processing, and finally combine these calculation results to overcome big problems. Cloud computing stage: The core of cloud computing is very similar to utility computing and grid computing, and it is hoped that IT technology can be as convenient and low-cost as electricity.

Cloud Computing [1] (English: cloud computing) is a computing mode based on the Internet, in which the software and hardware resources and information enjoyed by * * * can be provided to computers and other devices as needed. Cloud is a metaphor of network and internet. In the past, cloud was often used to represent telecommunication networks, and later it was also used to represent the abstraction of the Internet and the underlying infrastructure. Cloud computing is another great change after the large-scale computer transformed to client-server in the1980s. Users no longer need to know the details of the infrastructure in the "cloud", have corresponding professional knowledge or directly control it. Cloud computing describes a new IT service increase, use and delivery mode based on the Internet, which usually involves providing dynamically scalable and usually virtualized resources through the Internet, which means that computing power can also be circulated as a commodity through the Internet. The concept of "cloud computing" has been widely used in production environment. XenSystem of Alibaba Cloud and Yungu Company in China, and Intel and IBM which are very mature abroad, the service scope of various "cloud computing" is expanding day by day, and its influence is immeasurable. Cloud computing is often confused with grid computing, utility computing and autonomic computing. Grid computing: a kind of distributed computing, a super virtual computer composed of a group of loosely coupled computers, which is often used to perform some large tasks; Utility computing: A packaged charging method for IT resources, such as charging by calculation and storage like traditional public facilities such as electricity; Autonomous computing: a computer system with self-management function. In fact, many cloud computing deployments rely on computer clusters (but they are very different from grid in composition, architecture, purpose and working mode), and also absorb the characteristics of autonomous computing and utility computing. Quoted from sogou encyclopedia, I hope it will be useful to you.

Cloud is a metaphor of network and internet. In the past, cloud was often used to represent telecommunication networks, and later it was also used to represent the abstraction of the Internet and the underlying infrastructure. So cloud computing can even let you experience the computing power of 10 trillion times per second.
