This article will explain in detail the characteristics of cloud computing. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

The five characteristics of cloud computing are: 1. Flexible services; the scale of services can be rapidly scaled to automatically adapt to the dynamic changes of business load. 2. Resource pooling; resources are managed uniformly in the way of shared resource pool. 3. Service on demand. 4. The service can be charged. 5. Ubiquitous access; users can use a variety of terminal devices to access cloud computing services anytime and anywhere through the Internet.

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.

Cloud computing uses computer clusters to form a data center, which is delivered to users in the form of services, so that users can purchase cloud computing resources on demand just like using water and electricity. From this point of view, the goals of cloud computing and grid computing are very similar.

However, there are obvious differences between traditional distributed computing such as cloud computing and grid computing.

First of all, cloud computing is flexible, that is, cloud computing can dynamically allocate resources according to the size of workloads, while applications deployed on cloud computing platforms need to adapt to changes in resources and respond to changes.

Secondly, compared with grid computing, which emphasizes heterogeneous resource sharing, cloud computing emphasizes the sharing of large-scale resource pools, increases resource reuse through sharing, and reduces operating costs by taking advantage of economies of scale.

Finally, cloud computing needs to consider the economic cost, so the design of hardware equipment and software platform no longer blindly pursue high performance, but should comprehensively consider factors such as cost, availability, reliability and so on.

Based on the above comparison and combined with the application background of cloud computing, the characteristics of cloud computing can be summarized as follows.

1) flexible service. The scale of the service can be rapidly scaled to automatically adapt to dynamic changes in business load. The resources used by users are consistent with the needs of the business, avoiding the decline in quality of service or waste of resources caused by server performance overload or redundancy.

2) Resource pooling. Resources are managed uniformly in the form of shared resource pools. Using virtualization technology, resources are shared to different users, and the placement, management and allocation strategies of resources are transparent to users.

3) on-demand service. Provide users with applications, data storage, infrastructure and other resources in the form of services, and can automatically allocate resources according to the needs of users without the intervention of system administrators.

4) the service can be charged. Monitor the user's resource usage and charge the service according to the resource usage.

5) ubiquitous access. Users can use a variety of terminal devices (such as PC computers, laptops, smartphones, etc.) to access cloud computing services anytime and anywhere through the Internet.

It is precisely because of the above five features that cloud computing allows users to store personal email, store photos, buy music from cloud service providers, store profiles and information, interact with social networking sites such as Facebook,LinkedIn,MySpace, find driving and walking routes through cloud computing, develop websites, and interact with other users in cloud computing. Make it more convenient and fast for users to deal with life, work and other affairs. This is also an important factor why cloud computing can spread rapidly and become popular in a short time.

This is the end of this article on "what are the characteristics of cloud computing". I hope the above content can be helpful to you, so that you can learn more knowledge. if you think the article is good, please share it for more people to see.
