The method of selecting a CVM (CVM) is similar to that of other hosts. To select an appropriate CVM, you need to know about your website and the configuration parameters of the CVM as follows:

1. The situation of the website

Type of website

For example, whether it is static or dynamic, what website programs are used, what are the requirements for the running environment, and whether it is necessary to configure a specific environment, which will affect the choice of operating system and storage mode.

Number of visits to the website

How many people visit the website daily and how many people are online at the same time, which will affect the choice of CPU, memory, bandwidth, etc.

Data size of the website

How big the current data of the website is and whether it will increase rapidly in the future will affect the choice of hard disk.

Target users of the website

Whether the website is for national users or local users, which will affect the choice of computer room route.

After determining the situation of the website, you can make an estimation and selection combined with the configuration parameters of the CVM.

2. Configuration of CVM parameters

CPU:CPU represents the computing power of the host. If the traffic of the website is large and there are more dynamic pages, it is recommended to choose more than 2 cores of CPU.

Memory: memory is also an important factor in determining the opening speed of a website. The larger the memory, the larger the available cache, the faster the opening speed.

Hard disk: the size of the hard disk is determined according to the size of the website, and the remaining space should be taken into account in the choice. in addition, the reading speed of the hard disk IWeiO directly determines the speed of file reading.

Bandwidth: there is no traffic limit for the CVM, so the main consideration is bandwidth. Bandwidth is the direct embodiment of the opening speed of a website. The greater the bandwidth, the faster the opening speed. For websites with more visitors, it is recommended to choose a larger bandwidth.

Operating system: the choice of the system is related to personal familiarity and the specific situation of the website. You can choose which kind of operating system you know better. In addition, the Windows system supports ASP programs better, but takes up more memory, while Linux systems support PHP programs better, saving memory, and some programs only support a certain operating system.

Computer room line: line selection of appropriate computer room

Storage mode: 4 copies of distributed storage data are retained, while ssd solid-state disk is suitable for users who require higher reading speed of Icano.

If you are still not sure which configuration to choose, you can purchase a standard configuration to run for a period of time to observe, and if you find that the configuration is not enough, you can upgrade at any time.
