What is cloud computing? It has been nearly ten years since the concept of cloud was proposed. In this decade, cloud computing has undergone tremendous changes from its initial embryonic state to the present. It has already become a towering tree. The most basic cloud services of IaaS are extended to PaaS and SaaS cloud services, but many people still have a vague understanding of the concept of cloud computing. Let me tell you what cloud computing is? In fact, we all think of cloud computing as very complicated. Now let's use a metaphor to explain what cloud computing is? The most impressive cloud computing explanation, no longer afraid of not understanding!
The cloud is actually like the tap water of the family. Does our family need to build a water plant to drink clean tap water? It is obviously unnecessary to turn on the tap to get the water you want to drink. Cloud provides a model for everyone, just like flowing water. What you want in the future does not need a large hard disk, nor does your computer have a strong processing power. As long as you need it, you can get it at any time. This new computing mode has brought us a new way to obtain information in the ubiquitous network environment, or the information use mode is the cloud computing mode!
For example, Xiao Ming is in the excavator business. He bought three excavators. When Wang Village has a construction site, he will dig for Wang Village. When Li Village wants to build a house, he will dig for Li Village... In this way, Lao Wang of Wang Village and Lao Li of Li Village are happy. Finally, they don't need to buy excavators three times. Xiao Ming is also happy. With a good machine, I can make money by pulling it!
That is cloud computing. Lao Zhang and Li are clients, Xiao Ming is cloud, and mining is computing.
The above neutrino network explained cloud computing to you in the most popular terms, because everyone About We all know some concepts of cloud computing, and we can also take cloud computing as a business computing model. It is to put computing tasks into the resource pool of a large number of computers, so that users can obtain computing power, storage space and information services as needed.
We call such resources "cloud". Cloud computing is a kind of virtual computing resource that can be self maintained and managed. It is usually composed of large server clusters, including computing servers, storage services and other broadband resources. The so-called cloud computing is to collect the data in the resource library, realize unattended through automatic management, allow users to call resources automatically when using, support the operation of various programs, and focus on their own business without worrying about details. The core idea of the cloud is to run in a resource pool.
