The purpose of this article is to share with you about how to buy a CVM. The editor thinks it is very practical, so I hope you can learn something after reading this article. Let's take a look at it with the editor.

When you buy a CVM, what worries you most is to buy a fake CVM. Therefore, how to distinguish between genuine and fake CVM is very important. Now let's introduce the method.

First, for CVM, it can be configured independently, which generally allows users to configure common parameters such as CPU, hard disk, memory, bandwidth and operating system, while common vps hosts do not have so many operation permissions. Therefore, when you choose a CVM, if many configuration parameters cannot be modified by yourself, you should choose them carefully.

Second, most CVMs use pay-as-you-go mode, which is charged for the service category by calculating the time, and automatically controlled by the billing method. Users can integrate resources through storage, bandwidth and the number of users, which is very controllable.

At present, the cloud computing servers on the market are ready-to-use, while users can also choose according to their own needs, and in any quantitative way, unlimited purchase and use. If when purchasing a CVM, IDC merchants are required to specify how long to purchase, use a set configuration and make an one-time payment, these may not be real CVM, so beware of being cheated.

Third, the CVM has root permission, and users can reinstall or upgrade the operating system by themselves, while the vast majority of vps hosts do not have root permission, nor can they reinstall or upgrade the operating system on their own. Therefore, before purchasing, you can consult the cloud service provider if you can reinstall or upgrade the system, and if not, you should pay special attention.

Fourth, each CVM has its own independent IP, while the VPS host is not necessarily. So if the chosen CVM is a shared IP, it is likely not to be a real CVM. In addition, the CVM is a network distributed cluster storage, and multiple copies of data are backed up in real time, which is very powerful, so you can also identify it through data backup and storage.

Fifth, if the CVM is leased, users can obtain self-service computing resource capabilities without interacting with the host vendor, and provide self-service for server time, network storage and other resources, which is very convenient to try. These functional advantages are not available for general VPS hosts.

I hope the above methods of purchasing CVM can help you to distinguish between true and false. In order to avoid buying fake CVM, be sure to buy it from a regular big brand host, so that you can buy a real CVM. And Xinneng can also be guaranteed.

The above is how to buy a CVM. The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
