Three characteristics of cloud computing include

The three main characteristics of cloud computing include: on-demand self-service, network access and resource sharing, and rapid elastic scaling.
First of all, on-demand self-service means that users can freely obtain computing resources as needed without manual interaction with the cloud service provider. This service method provides users with great flexibility, and they can adjust resource usage at any time according to actual needs. For example, when an enterprise needs to perform large-scale data processing, it can independently increase computing resources through the cloud computing platform to meet the processing needs.
Secondly, cloud computing allows users to conveniently use various computing resources through network access and resource sharing without being restricted by geographical location. This means that users can access the computing resources of cloud service providers through the Internet to store, process and share data. For example, users can access data stored in the cloud through mobile phones, computers and other devices anytime and anywhere to perform various operations.
Finally, cloud computing has the characteristics of rapid elastic scaling. This means that cloud service providers can quickly increase or decrease computing resources based on user demand. This elastic scalability enables cloud computing to cope with various complex application scenarios and meet different user needs. For example, when the number of user visits to a website suddenly increases, the cloud computing platform can automatically increase computing resources to ensure the stable operation of the website.
In summary, cloud computing’s on-demand self-service, network access and resource sharing, and rapid elastic scaling enable it to provide users with efficient, flexible, and stable computing services.

Characteristics of cloud computing

The characteristics of cloud computing are as follows:

1. Virtualization technology

It must be emphasized that virtualization breakthroughs Breaking the boundaries of time and space is the most significant feature of cloud computing. Virtualization technology includes application virtualization and resource virtualization. As we all know, there is no spatial connection between the physical platform and the application deployment environment. It is through the virtual platform that data backup, migration and expansion are completed for corresponding terminal operations.

2. Dynamic scalability

Cloud computing has efficient computing capabilities. Adding cloud computing functions to the original server can rapidly increase the computing speed and ultimately achieve dynamic expansion of virtualization. Layers serve the purpose of extending applications.

3. On-demand deployment

The computer contains many applications, program software, etc. Different applications correspond to different data resource libraries, so users run different Applications require strong computing power to deploy resources, and cloud computing platforms can quickly allocate computing power and resources according to user needs.

4. High flexibility

Most IT resources, software, and hardware currently on the market support virtualization, such as storage networks, operating systems, and development software and hardware. Virtualization elements are unified and managed in the virtual pool of cloud system resources. It can be seen that cloud computing has very strong compatibility. It can not only be compatible with low-configuration machines and hardware products of different manufacturers, but also enable higher-performance computing with peripherals.

5. High reliability

Even if the server fails, it will not affect the normal operation of computing and applications. Because a single-point server fails, applications distributed on different physical servers can be restored through virtualization technology or new servers can be deployed for computing using the dynamic expansion function.

6. High cost performance

Placing resources in a virtual resource pool for unified management optimizes physical resources to a certain extent. Users no longer need expensive hosts with large storage space. Choosing relatively cheap PCs to form a cloud can reduce costs on the one hand, and on the other hand the computing performance is not inferior to that of mainframes.

What are the characteristics of cloud computing?

Characteristics of cloud computing:

(1) Virtualization. Cloud computing allows users to obtain application services at any location and using various terminals.

(2) Large-scale integration. The resources in the cloud are very huge. An enterprise cloud can have hundreds of thousands or even millions of servers, and a small private cloud can also have hundreds or even thousands of servers.

(3) High reliability. Cloud computing uses multi-copy fault-tolerance technology, isomorphic interchangeability of computing nodes and other measures to ensure high reliability of services. Using cloud computing is more reliable than using local computers.

(4) High scalability.

(5) On-demand services. Cloud computing is a huge resource pool that users can purchase as needed.

(6) Low cost.

System architecture of cloud computing service model. According to the level of resources provided by cloud computing services, it can be divided into IaaS (Infrastructure as a Service), namely desktop cloud, PaaS (Platform as a Service) and SaaS (Software as a Service).

System architecture of cloud computing service model

From the perspective of deployment mode, cloud computing can be divided into public cloud, private cloud and hybrid cloud. Public cloud services are open to everyone, while private cloud computing is only open to internal users of the enterprise. Hybrid cloud is a combination of public cloud and private cloud models.

According to the three major service models of cloud computing services, IaaS provides network resources, computing resources and storage resource services for the portal system, and belongs to the desktop cloud level.

PaaS provides the portal system with high-availability database cluster services and platform resources required for application operation and maintenance.

SaaS provides portal integration application services based on the SharePoint portal platform. , a cloud computing service SaaS software platform, said that the cloud computing management platform uniformly manages different computing resources and services, and automatically allocates and schedules computing resources according to changes in business needs and access volume of the portal system to achieve a high degree of "elasticity". scaling and optimization use.

The cloud desktop that is closest to life in cloud computing can be used by those who have high computer memory requirements for daily office work, games or 3D design.
