Due to the small price difference between vps hosts and CVMs, many users will ask questions such as the difference between vps hosts and CVMs and how to choose them. The following one of the connected editors will explain the difference between vps hosts and CVM in detail.

CVM

1. The mode of storage

The vps host mainly uses the server's local hard disk for storage, and there is only one copy of data, which needs to be backed up manually to ensure the security of the data. CVM is mainly network distributed cluster storage, and multiple copies of data will be written in real time, which has certain advantages for data backup.

two。 Capacity expansion

Because the vps host is split from the server, different users use different resources, so when users need to expand their capacity, there will be certain restrictions. When the utilization of mother machine resources reaches the highest level, the further expansion will be affected.

The most important feature of CVM is flexible expansion and dynamic load balancing. When the network bandwidth, memory and hard disk are insufficient, it can be flexibly expanded and configured.

3. Stability.

Since vps hosts seldom support hot migration and the mother machine fails, vps hosts will also have problems. CVM is mainly on the scale server cluster, and each server will have an image of the CVM. Therefore, if there is a problem with a CVM, it will be automatically migrated to other CVMs to continue to run. Therefore, in terms of stability, cloud services will be higher than vps hosts.

4. Anti-aggression

At present, many cloud service providers can provide application firewall and ddos high-defense server, but vps hosts rarely have such a defense capability, so their defense capabilities are incomparable.

Through our introduction above, we believe that everyone will have their own choice in choosing vps hosts and CVM. In fact, no matter how to choose, suitable for their own business development is the most important object.
