云计算领域的作用(云计算的认识与作用)

1. Concept
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 , these small programs are processed and analyzed through a system composed of multiple servers to obtain results and returned to the user. In the early days of cloud computing, to put it simply, it was simple distributed computing that solved task distribution and merged 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.
The cloud service mentioned at this stage is not just a kind of distributed computing, but a hybrid evolution of computer technologies such as distributed computing, utility computing, load balancing, parallel computing, network storage, hot backup redundancy and virtualization. And the results jumped.
2. Function
Cloud computing can provide flexible information resources and services on demand. Cloud computing is a take-on-demand, pay-on-demand model. Its core is to integrate all resources on the network through the Internet into a configurable shared pool of computing resources called "cloud", such as networks, servers, and storage. , application software, services, etc., and then uniformly manage and schedule this resource pool to provide users with virtual, dynamic, on-demand, and elastic services, gradually developing into a system based on computer technology, communication technology, storage technology, and database technology. comprehensive technical services.
Cloud computing can be divided into private cloud, public cloud and hybrid cloud according to deployment type. Different clouds correspond to different user groups. The core difference between private cloud and public cloud models is whether customers using cloud services have their own corresponding cloud infrastructure. The advantages of flexible configuration and low cost of the public cloud model are welcomed by small and medium-sized enterprises, while large enterprises pay more attention to the pertinence of solutions and information security, and are relatively insensitive to costs. At the same time, the deployment of public clouds in industries such as banking and electric power is also restricted. .
Cloud computing is currently widely used in computer technology. We are basically exposed to cloud computing every day. For example, we use mobile phones to surf the Internet, shop, online payment transactions, etc. These are all realized through cloud computing. We just didn't discover it ourselves. Nowadays, the application scope of cloud computing is expanding day by day, and its potential is immeasurable. Alibaba Cloud in China is a very successful case of using cloud computing.

1. The definition of cloud computing
In fact, as the name suggests, cloud computing is divided into two parts, one is cloud and the other is computing. We all know traditional computing, even from elementary school We started to get in touch. The key here is the cloud. In fact, we can also understand the cloud. The cloud is a metaphor for the network and the Internet. In this way, cloud computing can be understood as network computing and Internet computing. This is Isn't it easier to understand than cloud computing? I just need to simply know that cloud computing is a kind of network computing, and we use this kind of network computing every day. There is no need to delve into the infrastructure and principles of cloud computing. , because it’s hard for us to understand too.
2. What are the functions of cloud computing
Since cloud computing is a kind of network computing, then we can imagine how huge its role is. Why is the computer called Computers, because computers finally complete the instructions input by humans through countless operations. The operation of computers can be said to be based on operations.

What exactly is cloud computing and what is its role? This video will help you understand the most popular cloud computing concepts at the moment.

Concept: "Cloud" is essentially a network. In a narrow sense, cloud computing is a network that provides resources. Users can obtain resources on the "cloud" at any time and use them according to demand, and It can be seen as infinitely scalable, as long as you pay according to usage. The "cloud" is like a water plant. We can receive water at any time, and there is no limit. We only need to pay the water plant according to the water consumption of our home. Broadly speaking, cloud computing is a service related to information technology, software, and the Internet. This shared pool of computing resources is called a "cloud." Cloud computing brings together many computing resources and realizes automated management through software. It only requires a few steps. With fewer people involved, resources can be provided quickly. In other words, computing power, as a commodity, can be circulated on the Internet, just like water, electricity, and gas. It can be easily accessed and the price is relatively low. In short, cloud computing is not a brand-new network technology, but a brand-new network application concept. The core concept of cloud computing is to provide fast and secure cloud computing services and data storage on the website with the Internet as the center, allowing everyone to Anyone who uses the Internet can use the huge computing resources and data centers on the network. Cloud computing is another new innovation in the information age after the Internet and computers. Cloud computing is a big leap in the information age. The future era may be the era of cloud computing. Although there are currently many definitions of cloud computing, overall Although cloud computing has many meanings, in a nutshell, the basic meaning of cloud computing is the same, that is, cloud computing has strong scalability and demand, and can provide users with a new experience. Cloud computing The core is that it can coordinate many computer resources together, so that users can obtain unlimited resources through the network, and the resources obtained are not limited by time and space.
Function: Internet search engine and Internet mailbox. The most familiar search engines are Google and Baidu. At any time, as long as you use a mobile terminal, you can search for any resources you want on the search engine, and share data resources through the cloud. The same is true for online mailboxes. In the past, sending an email was a troublesome and slow process. However, driven by cloud computing and network technology, email has become a part of social life. , as long as it is in a network environment, real-time mail can be sent. In fact, cloud computing technology has been integrated into today's social life.
