Cloud hosts are the cloud server that we often say, the server is generally called, including extensive scope (virtual host, cloud host, physical host, etc.). This article mainly compares the cloud hosting and physical server, and analyzes the differences between the two.

　　Cloud host: Also known as the cloud server, it can be understood as a virtual server. Cloud hosts are divided into a group of cluster servers (can be divided into many). Each server in the cluster has a mirror backup of the cloud host. When there is a failure of the server in which the server, the system will automatically access the mirror backup on other machines.

　　Physical server: Physical server is a real existence. It has real physical equipment, such as hard disks, bandwidths, etc., whether in terms of performance and safety, which is much higher than the cloud host. The price of physical servers is relatively high.

　　Judging from the situation described above, physical servers in terms of price, performance, and safety are much stronger than the cloud host. Of course Cloud hosting is the most suitable choice. The performance of the cloud host can also meet our requirements in terms of performance, and the rental price is much lower than that of a physical server. Under normal circumstances, large websites will choose a physical server, and the choice of small and medium -sized websites is the most suitable. Of course, there are also large websites.

　　What are the differences between cloud hosting and server? We can see from the following points:

　　1. Technical level: use cloud computing technology to integrate various hardware and software technologies such as computing, network, storage. The physical server is independent and does not integrate resources.

　　2. Safety level: Cloud hosts have natural anti -ARP attacks and MAC deception, which can automatically use express -backed backup to ensure data security; physical servers do not have these functions.

　　3. Performance level: It is said that the cloud host uses a set of server clusters to automatically mirror backup. When a server fails, the system will automatically migrate the server on the beyond the server. The physical server requires manual maintenance.

　　4. Price level: The cost of renting a physical server can rent a lot of cloud hosts, which is more cost -effective in terms of cost performance.
