In life, if we want to speak on the Internet, we can leave messages in places like blogs or post bars, but your content is sometimes deleted, so how important it is to have your own website. It is very simple to set up a website, but what is important is what kind of space host you choose. The popular understanding of VPS hosts is to use virtual technology to divide physical servers into different spaces similar to independent hosts. Can have independent IP address, operating system and independent memory, CPU resources, etc., can also install programs and systems independently, can restart the server separately. For CVMs, it is similar to VPS virtualization technology, and its management method is the same as that of hosts. Different CVMs are concentrated on a cluster host, and each CVM has an image of the CVM. In this way, the CVM will not crash until all the hosts in the cluster have problems, and the security performance is particularly high. Hostwinds US cloud host VPS uses SSD hard drives, and all solutions have global CDN acceleration capabilities. You can learn more about it on the mainframe detective idcspy.com.

What is the difference between a CVM and a vps host?

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.
