What is the difference between a CVM and a vps host? CVM is a very popular network infrastructure, and users can automatically adjust computing resources according to business needs and scaling strategies. Compared with vps, the performance is superior!

Vps hosts are often sold as cloud servers by some unscrupulous merchants, that is, the so-called "fake cloud servers" in the market. Here's the difference between real cloud servers and "fake cloud servers"-vps.

1. Physical architecture support

The underlying layer of true CVM is composed of large-scale server clusters, which form a massive pool of computing, storage and network resources in the cloud, and the user needs are allocated as much as possible, thus forming an efficient use of resources.

Vps is served by an independent physical server, and hardware failures cannot be repaired automatically.

two。 Data storage

CVM is deployed in the cloud resource pool built by a large number of server clusters, and there is no single point of failure for network-based distributed data storage. Support the rapid reconstruction of different nodes, even if the computing node is abnormally interrupted or damaged, the virtual machine can be rebuilt through other nodes in a very short time without affecting the integrity of the data.

All the data of the vps host is stored in the local hard disk of a single server, so it is impossible to achieve distributed deployment, so it will always face the risk of machine hardware failure, and once a hardware failure occurs, it can not be recovered automatically and quickly.

3. Data backup

CVM lease supports snapshot backup strategy, which can write multiple data in real time. Even if user data is lost or mistakenly deleted, it can quickly schedule backup and recovery online, which is incomparable with traditional backup methods.

It is difficult for vps to provide real-time snapshot backup, and the most common way to handle it is for the administrator to export the backup data, repair it and then re-import it.

4. Heat transfer ability

Cloud computing servers support hot migration. Even if the hardware of an underlying server fails, user business can be migrated to other cloud servers online, and the migration process does not affect the normal operation of the website. This is something that fake clouds cannot do.

In case of hardware failure such as hard disk damage in vps, you can only manually transfer the data backup to another server to restore work, and only after you have completed the migration work can your website return to normal access.

Is an established well-known cloud service provider, cloud computing resources are flexible and can be adjusted at any time, excellent cloud architecture and computing capabilities to meet a variety of business requirements.
