What is the difference between cloud servers and general servers?

The difference between cloud servers and ordinary servers:

1. Cloud servers are virtual; ordinary servers are real physical devices.

2. Cloud servers have automatic data synchronization and backup functions by default; ordinary servers need to add hard disks as RAID to achieve automatic backup.

3. Cloud servers usually have relatively low configuration and bandwidth; ordinary servers have high configuration and sufficient bandwidth.

4. Cost: Cloud servers save hardware costs and are relatively cheap; ordinary servers cost relatively more.

5. Scope of application: Cloud servers are generally suitable for small and medium-sized websites or applications; ordinary servers are generally suitable for larger-scale websites and applications.

6. Technical aspect: Cloud server is based on cloud computing technology and integrates various software and hardware technologies such as computing, network, and storage. Physical machines will not integrate these resources;

7. Security: Cloud servers have natural protection against ARP attacks and MAC spoofing, snapshot backup, and data will never be lost. For example, Xun Cloud Server is divided into caching, precipitation, and backup layers. The three layers process, cache, and disaster recovery respectively. The three layers are synchronized in real time. Data security reaches 99.999%, and high availability reaches 99.99%. Physical machines do not have this function;

8. In terms of reliability: cloud servers are based on server clusters, so the hardware redundancy is high and the failure rate is low; while physical machines Relatively speaking, there is less hardware redundancy and a higher failure rate;

9. In terms of flexibility: cloud server users can add their own configurations online in real time, and the scalable space is large, and the cloud server provides A variety of instance specifications (CPU, memory), bandwidth, and cloud disks are available for users to choose from, and they can be upgraded at any time to meet various business needs; physical machines have limitations in this regard.

10. In terms of performance: cloud servers realize complete isolation between cloud hosts at the hardware level; high-end servers are used for deployment, and centralized management and monitoring are used to ensure business stability and reliability;

11. In terms of stability: Cloud servers can automatically migrate when faults occur, which means that if a cloud server fails, the applications on it will automatically migrate to other cloud servers. When a physical machine is down, it is down and cannot be saved.
