This article mainly explains "what's the difference between a virtual host and a cloud server". Interested friends might as well take a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn "what's the difference between a virtual host and a cloud server".

What is a virtual host?

Virtual host is the use of cyberspace technology, a server is divided into many "virtual" hosts, each cyberspace has an independent domain name and IP address, with a complete Internet server function. Cyberspace is completely independent, and in the outside world, each cyberspace is exactly the same as an independent host. The effect is the same, but the cost is very different. As multiple cyberspaces share the resources of a real host, the hardware costs, network maintenance costs and communication line costs borne by each cyberspace user are greatly reduced, and Internet has really become an affordable network for everyone!

What is a CVM?

Cloud server, also known as cloud computing server or cloud host, is a host product in the cloud computing service system. Cloud server is a virtualization technology similar to VPS server. It is also understandably an upgraded version of VPS, which is also different from VPS in that it is a division of multiple similar independent hosts on a set of cluster servers. Each server in the cluster will have an image of the CVM, and when one of the machines fails, it can be automatically redirected to other machines for access, so in theory, as long as not all the machines fail, the access of the CVM will not be affected, so the CVM is more powerful than VPS in terms of security and stability.

Cloud server is an important part of cloud computing services, and it is a service platform that provides comprehensive business capabilities for all kinds of Internet users. The platform integrates the three core elements of traditional Internet applications: computing, storage and network, and provides public Internet infrastructure services for users.

The difference between CVM and virtual host

Both CVM and virtual host integrate high-performance server and high-quality network bandwidth through technology, which effectively solves the shortcomings such as high rental price and uneven service quality of traditional hosts.

Virtual host adopts operating system virtualization technology, high virtualization efficiency, low virtualization License cost, can share operating system, does not provide real Root access, and can not run applications with high performance requirements without physical isolation, so it is only suitable for small-scale concurrent access. Security issues such as ARP spoofing, viruses, corrupted applications, and improper upgrade of the host operating system for one customer can affect all customers on the same physical host. The costs are relatively low, but the quality of service is often not guaranteed, which is limited to personal websites with less views or small business websites dominated by static pages. For example, when user websites or host applications focus on performance, reliability and meet the needs of large traffic, virtual hosting is usually difficult to meet.

CVM uses high-end brand servers for the deployment of cloud computing nodes, and each user monopolizes the host resources, so that different users will not face preemption of resources; good physical isolation ensures that hosts will not affect each other due to host failures of other users; high-quality IDC rooms cover the country to ensure a smooth user experience. Provide real-time OS, RAID and other status information, built-in monitoring and alarm functions, built-in anti-ARP spoofing, distributed deployment can slow down DDOS attacks, users can flexibly choose operating systems and software, can update and patch at any time. The leased cloud space distributed across multiple cloud computing nodes is centrally managed through the Web page.

At this point, I believe you have a deeper understanding of "what's the difference between a virtual host and a cloud server". You might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
