云计算具有的特点包括(云计算的关键特征包括)

The characteristics of cloud computing are:
1. Distributed computing and storage
2. Reliable operation
3. Centralized monitoring and management
4. Huge scale of cluster
5. On-demand services and convenient expansion
6. Rapid deployment
Xiaoniao Cloud focuses on providing one-stop core for individual developer users, small and medium-sized, and large enterprise users. Network cloud deployment services enable users to simplify cloud deployment to zero and use cloud computing easily and quickly.

What are the characteristics of cloud computing technology?

The characteristics of cloud computing include virtualization, elastic expansion, network sharing, etc. .

1. Virtualization

Cloud computing abstracts computing resources (such as servers, storage devices, network devices, etc.) through virtualization technology, allowing users to Ability to allocate and use these resources as needed. This virtualization method greatly improves resource utilization and reduces costs.

2. Elastic expansion

Cloud computing can dynamically increase or decrease computing resources according to changes in user needs. Users can adjust computing capabilities according to business needs and achieve elastic expansion. This flexibility enables users to flexibly adjust the use of resources according to actual conditions, improving efficiency.

3. Network sharing

Cloud computing realizes resource sharing and access through the Internet. Users can connect to the cloud service provider's server through the network to obtain the required computing resources and services. This network sharing method allows users to easily access and use various services provided by cloud computing.

Advantages of cloud computing:

1. Flexibility and scalability

Cloud computing allows users to dynamically deploy data based on actual needs. Adjust computing resources. Users can quickly increase or decrease computing power according to business needs to achieve elastic expansion and avoid the waste or shortage of resources in traditional IT systems.

2. Cost-effectiveness

Cloud computing adopts a pay-as-you-go model. Users only need to pay for the resources actually used, avoiding the cost of purchasing expensive hardware equipment and software licenses. In addition, cloud computing also saves the cost of maintaining and managing hardware equipment and reduces the investment in human resources.

3. High availability and fault tolerance

Cloud computing provides high availability and fault tolerance services by performing data backup and redundant storage on multiple data centers and servers. Even if a node or server fails, the system can still maintain normal operation to ensure business continuity.

4. Data security and privacy protection

Cloud service providers usually have professional security teams and security measures that can provide a high level of data security. and privacy protection. User data is backed up and stored in the cloud, which is not easily lost, and can be protected through permission control and encryption.

5. Disaster recovery and backup

Cloud computing can provide users with disaster recovery and backup services, backing up data to remote data centers to prevent data loss and disasters. Data Recovery. This disaster recovery and backup service can greatly improve the reliability and security of data.

[Answer]: A, C, D
Cloud computing (cloud computing) is the addition, use and delivery model of Internet-based related services, usually involving the provision of dynamic services through the Internet Easily scalable and often virtualized resources. Cloud computing has the characteristics of security, ultra-large scale, virtualization, high scalability and minimal requirements for user-side equipment, so it does not require high energy consumption.
