What configuration should I choose to buy a CVM? In view of this problem, this article introduces the corresponding analysis and answers in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible way.

In recent years, cloud servers have become the first choice for enterprises and webmasters to build stations. Compared with traditional stand-alone servers, CVM is more reasonable in price, easy to operate and easy to manage. However, today's cloud service providers are mixed and the quality of their products is uneven. We need to consider the configuration of these aspects when we buy a CVM.

How much is CPU and memory?

CPU represents the computing power of the host. If the website traffic is large and there are more dynamic pages, it is recommended to choose more than 2 cores of CPU. Memory is also an important factor in determining the speed of website opening. The larger the memory, the larger the available cache and the faster the opening speed. The windows operating system does not support the selection of 512MB memory.

How big is the hard disk and bandwidth?

The size of the hard disk should be determined according to the size of the website, and the remaining space should be taken into account when choosing. In addition, the read speed of the hard disk directly determines the reading speed of the file. The reading speed of the hard disk of the CVM is much faster than that of the virtual host, which is generally sufficient. Bandwidth is a direct reflection of the opening speed of a website. The greater the bandwidth, the faster the opening speed when you visit. For websites with a large number of visitors, it is recommended to choose a large bandwidth.

Can there be multiple backups?

For traditional servers and web spaces, it is a single point of backup. The CVM uses network distributed cluster storage, and the data is read and written in multiple backups in real time. For those fake CVMs, the data is only stored on the local hard disk. Once the server fails, there is a risk of data loss. This is the essential difference between true clouds and false clouds.

Smooth upgrade required

Due to the cluster cloud computing technology used in the cloud service, the cpu, bandwidth and data disk of the host can be smoothly upgraded online, and there is no need to reconfigure the server environment. The traditional host rental, but also need to buy hardware to rebuild the environment, time-consuming and laborious, prone to failure and data loss.

Achieve rapid migration

We will inevitably have some failures in the use of the server. For a CVM, if a server fails, the above CVM can be instantly migrated to other nodes through the hot migration feature without business interruption and no need to restart. However, once vps encounters a server failure, it usually needs to stop operation, and the interruption time is relatively long. Therefore, the CVM needs to be migrated quickly.

The answer to the question about which configuration to choose to buy a CVM is shared here. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel to learn more about it.
