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

Conceptually, a cloud server is essentially different from a cloud virtual host.

In the era of VPS, using virtualization technology, a physical server can be divided into multiple virtual machines, and there are few solutions for clustering multiple physical machines. The emergence of cloud computing technology brings clustering to the extreme and greatly improves the reliability of services, while the concept of distributed storage improves the reliability of data, and a new era of virtualization has come.

Cloud is cloud computing, cloud server is the most basic product in the era of cloud computing.

Cloud host is an important part of cloud computing in infrastructure applications, which is located at the bottom of the pyramid of cloud computing industry chain, and the products come from cloud computing platform. The platform integrates the three core elements of Internet application: computing, storage and network, and provides public Internet infrastructure services for users. A CVM is a part that virtualizes multiple independent hosts on a group of cluster hosts, and each host in the cluster has an image of the CVM, thus greatly improving the security and stability of the virtual host. The CVM cannot be accessed unless all the hosts in the cluster have problems.

The virtual host is to build a specific application environment (such as the WEB application environment) in the physical server to become a dedicated server, while the cloud virtual host is a virtual host deployed on the cloud server.

Is the security different?

Many people think that cloud servers are more secure than virtual hosts. Because it needs to be divided into scenes.

A CVM is a server with an independent operating system. No matter how secure the cloud vendor is, there are loopholes caused by the user's own lack of technology, such as port, program usage, operational failure, and so on. The cloud virtual host is a website server environment customized by the cloud manufacturer, so it will deal with a lot of security issues, and the only insecure place is the user's website code.

The characteristics are different:

Cloud virtual hosts generally share IP, and an IP is used by many people. Of course, there is also an exclusive IP. The virtual host cannot install the software on its own and is installed and configured by the manufacturer. Generally speaking, you can only put on the website or store information.

CVM generally has a separate IP address and must have a separate operating system, which can be remote Desktop Management (Windows) or SSH connection Management (Linux). You can install any software or service you need, including making a website, with a wide range of uses.

At this point, the study on "what's the difference between a cloud server and a virtual host" 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!
