In this issue, the editor will bring you the difference between the cloud host and the virtual host. The article is rich in content and analyzes and narrates it from a professional point of view. I hope you can get something after reading this article.

Both the CVM and the virtual host can be used to build a station, with functional similarities and many different differences. So, what is the difference between the two in application?

Elastic expansion

CVM can support flexible expansion and pay on demand. When server performance cannot meet the needs of website business development, users can expand their capacity at any time and upgrade host CPU, memory, hard disk and bandwidth configurations. There is enough business buffer space, while upgrading or expansion of virtual hosts is relatively troublesome, and new space needs to be rented.

Safe and reliable

Based on cloud computing architecture, CVM can automatically switch failed nodes to normal hosts with strong stability, built-in ARP prevention, large-scale enhancement of ddos and virus anti-attack capabilities, and provides a variety of data recovery measures such as snapshots and mirrors. Some virtual hosts are now all located in the cloud technology platform, and their security and stability are also strong. However, due to the sharing of resources such as CPU, bandwidth or IP, the performance is still slightly lower, and the anti-attack capability is not as good as that of CVM.

Cost of ownership

The price of the virtual host is low, and the station can be built at least dozens of yuan, so it has become the first choice for many individual webmasters. However, with the continuous upgrading of cloud technology, the overall cost of ownership of CVM is also reduced year by year. Many service providers still have multi-year discounts, such as an one-time purchase of 50% of the province in 5 years, which costs only 1.36 CNY / day after conversion, to fully enjoy the cost-effectiveness of large-scale IT practice.

Available resources

CVM rental is an exclusive resource, with independent CPU, memory, hard disk and IP addresses, so that you can build more websites and store more files, and it is easier to operate on SEO optimization. Virtual host means that many websites share a server resource, and there are usually restrictions on CPU performance, bandwidth, space, traffic and other parameters.

Management aspect

The cloud computing server can log in remotely, has a centralized remote management platform, and can configure the environment by itself, but at the same time, there is also a certain threshold for technical operation; the virtual host environment is all configured by the business. users can not change and do not need to configure their own website space environment, there is no technical difficulty, management is more convenient, easier to use.

The above is the difference between a CVM and a virtual host shared by Xiaobian. If you happen to have similar doubts, please refer to the above analysis to understand. If you want to know more about it, you are welcome to follow the industry information channel.
