Today, I will talk to you about how to choose a cloud server. Many people may not know much about it. In order to make you understand better, the editor has summarized the following for you. I hope you can gain something according to this article.

Cloud server is favored by many enterprises because of its powerful performance, convenient operation and simple management. How to distinguish the authenticity of the cloud servers provided by various brands in the market should be viewed from the following aspects.

1. Storage: see whether the service provider uses local storage or distributed storage. When the physical server where the VM is located has a hardware failure (such as damage to the motherboard), can you switch the CVM to another backup node and restore the service within 5 minutes?

two。 Private network: if 10 CVMs are needed, is there a private network connection between these 10 CVMs? Is it a private intranet?

3. Migration: whether hot migration is supported. Because the load of the original cluster is too high, whether it can be hot migrated without downtime and whether the IP remains the same when you need to migrate to a new cluster. The physical computing server will definitely be upgraded in the future, and whether it will cause the interruption of the CVM during the maintenance of the physical server.

4. Expansion: whether you can expand the content, the hard disk, the bandwidth, whether the server needs to be migrated and how long the interruption is.

Some unscrupulous merchants will use vps to sell as a cloud server. Vps is a server that provides services for multiple users. The bandwidth, hard disk IO performance and CPU capability of these VPS sub-servers are all limited by the performance of this "parent server". If the parent server has hard disk damage, motherboard damage, etc., all of the above VPS servers will be down and it will take a long time to restore service.

A CVM is a cluster of several servers that provide services at the same time. The downtime of one or two servers in the cluster does not affect the normal use of the CVM. The disk IO performance, bandwidth and memory of the CVM are not limited by a single server, and can be expanded flexibly and conveniently. Therefore, a server serving multiple VM is a fake cloud, while multiple servers serving a VM at the same time is the real cloud!

When choosing a CVM provider, users should identify the reliable brand and recommend the CVM to ensure their professional quality.
