In this issue, the editor will bring you about the differences between cloud servers and physical servers. The article is rich in content and analyzed and described from a professional point of view. I hope you can get something after reading this article.

The most macroscopic classification of servers is physical servers and cloud servers. With the progress and development of science and technology, the way many enterprises use servers has gradually changed from traditional physical servers to cloud servers. Let's list the comparison between the two below.

Compared with the project physical server CVM product defines that the physical server is real and visible to the naked eye, which is made up of software and hardware configuration. CVM is a cloud virtual resource pool based on a massive physical server cluster. Resource expansion completely enjoys the configuration resources of the whole machine, has the highest administrative rights, and is free to set any level of security configuration and all other operations. According to online demand, resources are scheduled and allocated from the resource pool, so it has the flexibility to change as needed. Its performance is determined by the performance of the underlying server and the performance of cloud computing platform. Security and reliability physical server rental supports the free construction of any required security settings to maximize the security of websites or applications. Cloud servers are based on cloud security platform and can be hot migrated. Virtualization technology is used to make each user have a separate and relatively independent space. The host price physical server must purchase the server and related hardware configuration independently, the cost is high. CVM uses technology to achieve data storage, which has a lower comprehensive cost and is cheaper than physical servers. It takes days to weeks to supply deployment time for the overall deployment of the physical server. The CVM can successfully install the server system program in a few minutes, and you can build one-click deployment.

However, the CVM is also deployed on the physical machine, and abnormal performance of the underlying physical machine or other reasons will lead to physical machine downtime. When a failure is detected in the physical machine where the CVM resides, the system will start a protective migration and migrate the server to a host with normal performance. Once the downtime migration occurs, the server will be restarted.

If you want the application server to recover automatically after the server restarts, you need to set the application to boot automatically, and if the application service connects to the database, you need to set the automatic reconnection mechanism in the program.

Generally speaking, the performance-to-price ratio of cloud servers is higher than that of physical servers, which is more suitable for small and medium-sized enterprises and webmasters. CVM users can freely choose CPU, memory, data disk, bandwidth and other configurations according to different needs. They can also upgrade bandwidth without downtime at any time, and upgrade CPU and memory within 1 minute to support the continuous development of the business.

These are the differences between CVM and physical server shared by Xiaobian. If you happen to have similar doubts, please refer to the above analysis to understand. If you want to know more about it, you are welcome to follow the industry information channel.
