What are the advantages and disadvantages of CVM? Many novices are not very clear about this. In order to help you solve this problem, the following editor will explain it in detail. People with this need can come and learn. I hope you can gain something.

Now a lot of people use cloud servers, because its advantages are obvious and easy to use, so many businesses have launched cloud server products. CVM stores hardware resources in the cloud for segmentation and leases them out, which has both advantages and disadvantages.

Advantages of CVM:

First, CVM deployment is very fast. Regular servers need a series of resources to be configured on the shelf, and a suitable operating system needs to be installed according to the language type, which requires a lot of time and effort. CVM rental can obtain resources to complete the delivery of the server in a few minutes.

Second, the scaling of the CVM is flexible, and the CVM can allocate resources according to the current affairs needs of customers, which is not only flexible and efficient, but also does not waste resources. The ordinary server needs to be estimated artificially, because the bandwidth and resources need to be set in advance, so the estimation should be as accurate as possible, otherwise the estimation is too small, the resources are not enough, and the server will crash instantly. If the estimate is too large, there will be a waste of resources.

Third, the operation and maintenance cost of the cloud computing server is lower, because the operation of the cloud server is simple, and the cloud service provider is responsible for it, and users only need to maintain the internal problems of the cloud server, so compared with the traditional server, operation and maintenance is easier.

Fourth, if an accident occurs when a CVM is leased, the data can be migrated effectively. Because the CVM has the ability of automatic repair and hot migration, even if there is a hardware failure or fire, the CVM can quickly migrate the data and continue to use it.

Fifth, the price is more affordable, because the CVM does not need to customize resources in advance and pay according to the resources you actually need, which is more user-friendly and cost-saving.

Disadvantages of CVM:

First, users of CVM do not have as strong control over data as traditional servers, because traditional servers are fully used by users, and the stored data can only be seen by themselves, while CVM uploads data to the public cloud. If the cloud is attacked, the data is easily stolen. However, the current cloud security strategy is advanced and can be protected effectively.

Second, the cloud server is completely dependent on the network, and the data can be seamlessly migrated in the case of a network, but not in the case of a network. Now the Internet coverage is very high, and there are very few places without the Internet.
