The purpose of this article is to share with you about the difference between a CVM and a stand-alone server. The editor thinks it is very practical, so I hope you can learn something after reading this article. Let's take a look at it with the editor.

CVM has been greatly improved in flexibility, controllability, scalability and resource reusability. With the same function and usage as the server, independent IP and bandwidth, users can install a variety of operating systems and configure a variety of website operating environment according to their needs.

Stand-alone server: is a separate physical server, on which only the user's own content, user websites or applications enjoy the software and hardware resources of this server.

CVM: multiple independent servers are virtualized on a group of cluster servers. It is an elastic cloud technology based on WEB service that provides adjustable CVM configuration, Iaas services that integrate computing, storage and network resources, and CVM leasing services with on-demand use and instant payment on demand.

Different storage modes

The cloud server is divided by the cluster server, using network distributed storage, multiple copies of data can be retained in real time, even if the data is damaged, it does not affect the normal operation of the server. On the other hand, the stand-alone server only stores a copy of the data on the hard disk of the local physical server, which will not work properly if it is damaged.

Reliability difference

The CVM is supported by multiple servers, which can achieve hot spot migration and automatic switching of failed nodes. Each server in the cluster has an image of the CVM. When one of the machines has a hardware failure, the system automatically accesses the image backup on other machines.

Unless there are problems with all the servers in the cluster, the CVM will not be accessible, which improves the stability and security of host leasing, and ensures the normal operation of the website when the server needs to be upgraded or restarted.

The above is the difference between a CVM and a stand-alone server. The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
