This article introduces the relevant knowledge of "what are the advantages and disadvantages of the CVM". In the operation of actual cases, many people will encounter such a dilemma. Then let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Advantages of CVM:

First, cheap.

Because services can be distributed to multiple servers, resources can be fully utilized, thus reducing hardware, power, and maintenance costs. Moreover, the CVM is billed according to usage, using more and paying less, so it is especially beneficial to small websites.

Second, reliable.

Because the service is distributed in multiple servers or even multiple computer rooms, it is not easy to go down completely, has strong anti-disaster and fault tolerance, and can be online for a long time.

Third, good scalability (scalability).

The basic characteristic of the cloud host is the distributed architecture, so it is easy to increase the server and expand the service capacity exponentially.

Disadvantages of CVM:

Some customers are worried about the security of the cloud host and feel lack of control over the service.

Because the CVM only provides the network interface, the customer's data must be arranged by the cloud service company and completely under the control of the latter. Whether the data is safe and confidential depends on the professional ethics and protection ability of the latter.

In most cases, cloud service companies care more about and are better at protecting data than their customers. Some big companies feel that they can't give us their customers' credit card information, but it's safer to put it on their own servers. But in fact, their servers are not as secure as ours, and our data protection is almost certainly better than theirs.

Think about it, who can hire a higher level of cyber security expert, a technology startup whose business is to manage servers, or a clothing retailer? And we are more concerned about data security than they are. If a clothing retailer's server is hacked into, at most, only the company itself, the matter is likely to be covered up within the company, and in the worst case, an employee may be fired. However, if our servers are hacked, thousands of companies may be affected, and this incident may also be published as news on industry websites, making it impossible for us to do business and have to go out of business.

If you want to hide your money in a safe place, do you choose under the mattress at home or the bank? This metaphor applies to all aspects of server management, not only security, but also uptime, bandwidth, load management, backup and so on.
