This article mainly introduces "what's the difference between a virtual host and a cloud server". In daily operation, I believe many people have doubts about the difference between a virtual host and a cloud server. The editor consulted all kinds of materials and sorted out a simple and easy-to-use operation method. I hope it will be helpful for everyone to answer the question of "what's the difference between a virtual host and a cloud server?" Next, please follow the editor to study!

Virtual host is the use of cyberspace technology to divide the server into multiple "virtual" hosts. Each cyberspace has a separate domain name and IP address, and has a complete Internet server function. Cyberspace is completely independent. From the outside world, each cyberspace is exactly the same as a separate host. The effect is the same, but the cost is very different. Because multiple cyberspaces share the resources of real hosts, the hardware cost, network maintenance cost and communication line cost of each cyberspace user are greatly reduced, and the Internet has really become a network that everyone can afford.

Virtual host function

1. Low cost, suitable for beginners

2, easy to manage, no need to configure the website environment, upload the website program.

3, sharing resources, lack of stability.

Advantages and disadvantages of virtual host

1. Advantages

Because it is shared server bandwidth, IP and so on are cheap. Virtual hosts are usually used by users who have configured the environment, and it is very convenient for customers to purchase and use them.

2, shortcomings

Because the bandwidth is shared, the bandwidth of the virtual host cannot be guaranteed. IP sharing is not secure. Because all virtual hosts that are separated from each other in anti-attack are not strong.

What is a CVM?

Cloud server, also known as cloud computing server or cloud host, is the host product in the cloud computing service system. CVM is a virtualization technology similar to VPS server. It can also be understood as an upgraded version of VPS. Unlike VPS, it is part of multiple independent hosts divided on a set of clustered servers. There is a cloud host image on each server in the cluster. When one of the machines breaks down. You can automatically jump to another computer for access. So in theory. As long as not all machines break down. It will not affect the access of the CVM. Therefore, the CVM is more powerful than VPS in terms of security and stability.

CVM feature

1. Flexible expansion, configurable upgrade, pay-as-you-go

2. Simple and efficient, no need to buy machines in advance, use them at any time, and deploy business quickly.

3. Independent operating system, isolating the dedicated bandwidth of hardware resources

4. Centralized remote management platform multi-level service backup

Advantages and disadvantages of CVM

1. Advantages

Independent IP, independent bandwidth, server speed is guaranteed, independent IP can better protect the security of the site. At the same time, the cloud server also has a mirroring function, which can avoid the loss of server data and further ensure the security of the website.

2, shortcomings

The cost is lower than the traditional server, but higher than the virtual host. The environment configuration of the server needs to be built by itself, and it must be professional.

The difference between virtual hosts and cloud servers

1. CVM can support flexible expansion and pay on demand, but virtual host does not.

2. The CVM needs to configure the environment manually, and the virtual host does not need to configure the environment

3. CVM is an exclusive resource that shares the resources of virtual hosts.

4. CVM can be managed remotely, and virtual hosts can only be managed through ftp.

The difference between the operation of virtual host and cloud server

(I) supply and deployment time

Web hosting-days to weeks

CVM-instant, can be completed in a few minutes, can be deployed with a button, or can install the operating system independently

(2) safe and reliable

Virtual hosts-generally: rented white card servers have a high failure rate, basically no ARP, Trojan and DDOS defense functions, and basically no backup and data backup services

CVM-High: built-in ARP protection to expand DDOS anti-attack capabilities; share the performance and reliability of brand enterprise servers and hardware virtualization. Built-in HA; provides a variety of fast recovery measures, such as backup, snapshot, data backup, etc.

(3) performance and security

Virtual host-good and secure

CVM-good and secure: same physical server

(4) flexibility and scalability

Virtual hosts-capacity expansion requires renting new servers and paying for original leased resources

CVM-instant configuration and on-demand expansion without paying for the original leased resources

(5) cost of ownership

Website hosting-High quarterly costs paid by service providers through capital expenditures; maintenance of leased servers to make Opex higher

CVM-lowest comprehensive cost: no monthly savings, no on-demand, on-demand payment, basic zero maintenance, and can share the cost advantages of large-scale, green energy saving and best IT practices

(6) easy to use and manage

Virtual host-need a remote control card, can only rent brand machine, can not achieve centralized management

CVM-built-in KVM, which allows customers to centrally and centrally manage distributed CVMs through the self-service system; fully own root or Super Admin operating system permissions.

At this point, the study on "what's the difference between a virtual host and a cloud server" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
