How should I select the appropriate parameters for the CVM? The parameters for selecting a CVM should be based on your website needs and budget. Let's introduce how to select a CVM from several different angles.

How much space is needed for storage?

This problem needs to be calculated from two angles, one is what types of data, including: the space occupied by the operating system itself, the space needed to install the application, the data generated by the application, the database, log files, mail data, and so on. If it is a Web2.0 site, you also need to calculate the storage space for each user.

Second, from the perspective of the timeline, these data are growing every day, and you need to make at least an accurate estimate of data growth in the next year (recommended 2-3 years), which may still require software developers and business people to provide enough information together. Finally, you still need to multiply the calculated results by a coefficient of about 1.5 to facilitate maintenance to do a variety of data backup and file transfer operations.

Region of the server

That is, the region where the CVM data center is located, it is best to choose the area where your main target users are located, so that the website will open faster.

Operating system selection

Related to personal familiarity and the specific conditions of the website, choose which operating system you know better. In addition, the windows system supports asp programs better, but takes up more memory, while Linux systems are more friendly to php programs and save memory, and some programs may only support a certain operating system.

Selection of computer Room Route

If it is for local users, you can choose a single-line server, but the advantage of dual-line server generally lies in double IP, and for a city, broadband telecom and Netcom are different. So at this time, choosing two-line may be a better way to achieve the user experience.

The above is an introduction to how to select the parameters of the CVM. In short, if the budget allows, the priority of performance elements of the CVM depends on the specific application. For high computing requirements, give priority to memory, CPU;, high access requirements, bandwidth, memory, and so on.
