How to choose the configuration of a CVM? Many novices are not very clear about this. In order to help you solve this problem, the following editor will explain it in detail. People with this need can come and learn. I hope you can gain something.

In the construction of the station, many novice webmasters lack experience and do not know how to choose the appropriate CVM configuration. Let's introduce it to you below.

Principles of CVM configuration

When purchasing a CVM, the priority of performance elements depends on the specific application. If there are high computing requirements, priority will be given to high CPU and large memory; for high access requirements, priority will be given to large bandwidth and BGP lines; for high storage needs, priority will be given to large hard disk and SSD storage mode; in terms of daily management and maintenance, certain technical services will be matched according to the needs of practical applications.

If you want to save the IT budget, after determining the server configuration, you can choose a multi-year purchase option with more discounts. For example, CVM offers multi-year discounts as low as 50%.

CVM configuration parameters

CPU/ memory

For general corporate websites or personal websites, there may not be many visitors, so you can choose 2-core CPU or 2G/4G memory; if it is a large forum or web game, it will not only have more visitors, but also generate a large number of data requests, so you should give priority to CPU4 core + and memory 8G + when choosing.

Storage mode

Distributed cluster storage is the default option, there are multiple cloud storage nodes inside the device, and the server data is written to multiple copies in real time, which supports automatic backup and recovery, which effectively avoids a single point of failure and improves data security. Provide SSD solid state disk option, in addition to very fast read and write, there is also a certain advantage in data collection, because the data stored in the flash memory is only temporarily marked for deletion but not overwritten by the new data after the delete operation, so it is possible to recover the data that is deleted only in the file system. The hard drive is generally sufficient, so choose the default recommended configuration.

Bandwidth

The host leased bandwidth is selected according to the nature of the website, which mainly depends on the type, structure and traffic of the website. Generally speaking, there are not many pictures on the new website, and they have been dealt with. 2m is enough. Or choose 2m first, not enough to add, so it is safer. If it is an ordinary website, such as text website, picture website, forum, etc., the bandwidth is very small, and 5000 visitors may use less than 2m bandwidth; if it is a website dominated by video, download, etc., hundreds of people need to occupy more than 10m of bandwidth online at the same time.

Computer room line

That is, the region where the CVM is located, it is best to choose the area where your target users are located, so that the website and so on can be opened faster. CVM provides a variety of common data center line types, and different lines have their own advantages. Among them, telecom equipment room supports IPV6, high-defense lines are equipped with 500G hard defense, and Hong Kong data center does not need to be registered. If the user coverage is wide, it is recommended to choose multi-line or BGP data center.
