Let's follow the editor to learn more about "how to choose a cloud server".

CVM has become a new favorite in the IDC industry. CVM rental is an important part of enterprises' deployment of cloud computing. What problems do you need to pay attention to when leasing?

First, unlike virtual hosts, there may be more issues to consider when choosing a CVM, such as the line of the computer room, the bandwidth, the space, the configuration of the system disk and the data disk, and which operating system is more suitable for the CVM. At the same time, because the cloud server is relatively new, many people do not know enough about the characteristics of the cloud server, and there may be some problems in the choice.

Second, CVM lease actually does not have property rights, which may be different from traditional servers when in use. CVM is a cloud computing server provided through virtual technology, which is similar to virtual hosts. At the end of the use cycle, we will not be able to retrieve the "host" server data, which must be properly backed up.

Third, the ultra-flexible configuration of the cloud server. The elastic cloud configuration provided by China Network Technology can choose a variety of configurations. The computer room can be selected through the area where its main customers are located, because the configuration can be upgraded appropriately. However, the computer room line can not be changed independently (in special cases, you can apply for the company to change the line). This is very critical, and it also needs to be tailored when configuring. Those with a large number of visits can consider increasing the bandwidth, those with a large number of pages can consider increasing the number of CPU cores, and those with constant requests to the database need to consider more memory consumption.

Fourth, pay attention to the backup mechanism of the CVM, such as the snapshot backup of the elastic cloud, on the one hand, through the automatic backup of the system, on the other hand, you can increase the insurance factor with the help of third-party backup, so that the CVM is more comfortable to use.
