What are the characteristics of CVM and stand-alone server? With the rapid development of cloud computing and the increasing use of cloud technology in the Internet, more and more IDC companies provide cloud hosting services for users. In the server and cloud hosting business, some users do not know how to choose the products that meet the development needs of their own enterprises.

A CVM is a part of multiple independent hosts that are divided into a group of cluster servers. Each machine in the cluster will have a mirror backup of the CVM. When one of the machines breaks down. The system can access backups on other machines on its own. Therefore, CVM is more powerful than vps in terms of security and stability.

A CVM has the following characteristics:

1. Better price: zero down payment, zero deposit, zero maintenance, monthly payment, monthly use, lower price for the same performance.

2. High reliability: the host service supports multi-level backup and recovery, including standby, system backup and application backup.

3. Security: achieve fault isolation from the hardware level, built-in ARP attack protection capability, distributed and large-scale to improve the ability to prevent ddos attacks.

4. Self-service: through the browser-based self-service interface, customers can remotely install the operating system and remotely manage the CVMs distributed in different data centers, saving worry and effort.

5. High performance: the host business unit is independent, monopolizes hardware resources, provides exclusive bandwidth, and ensures high performance.

6. Fast supply: provide a variety of standard images of operating systems and applications, whether one or a hundred, Windows or Linux, can be instantly supplied and deployed.

Characteristics of stand-alone servers:

A stand-alone server is a real physical device. It is very powerful in terms of performance and security. On the one hand, the hardware is relatively stable in the process of running. On the other hand is physical hardware. The performance is very strong, under the same configuration. The performance of CVM is not as good as that of stand-alone server. In terms of safety, it is appropriate for people. Because it also has something to do with the usual usage habits and the understanding of safety common sense.

If the performance and security requirements are high, you can choose. In pursuit of higher performance-to-price ratio, it is still a cloud host, which is much cheaper than server rental after all.

After understanding the characteristics of CVMs and stand-alone servers, users can make choices according to their needs. Recommended for cost-effective CVM.
