There are cloud virtual host, VPS host and cloud server for the cloud services in server renting. Because these three servers have similar names and functions, it is not clear to distinguish them. So what’s the difference between the three?
- Cloud virtual host, also often referred to as “virtual space”, “space”;
The main difference between the virtual host and the other two cloud hosts is that the virtual host does not need users to deploy the website environment, usually by default to support a variety of website environment, users can directly upload the website installation can be used. The VM space cannot be connected to the desktop for other operations. Therefore, the server tenant provides a control panel for simple operations such as domain name binding and file decompression.
From a technical point of view, virtual host is the use of special software and hardware technology, a real physical computer host is divided into multiple logical storage units, each unit has no physical entity, but each logical storage unit can work like a real physical host on the network, A single domain name, IP address (or shared IP address), and full Internet server functionality.
Virtual host is a server is divided into a number of virtual hosts of a certain size, each virtual host has given separate FTP permissions and Web access permissions, the disadvantage is that resources are shared, such as IP, bandwidth, CPU and memory.
- VPS host
VPS host is a high-quality service that divides a Server into multiple Virtual dedicated servers by using Virtual Private Server (VPS) technology, that is, a real host is Virtual into multiple small hosts. Each VPS can be assigned an independent public IP address, independent operating system, independent space, independent memory, and independent CPU resources. Each VPS can be remotely connected to a desktop, equivalent to a fully functional computer. In addition to users can allocate multiple virtual host and unlimited enterprise mailbox, but also according to the demand to replace the operating system, installation, deployment environment and restart the server, that is to say, VPS host relative virtual host for a higher level, higher degree of freedom;
- Cloud server
The above VPS host is made up of a real host virtual into a number of small hosts, performance is often not guaranteed, so what about the cloud server?
Cloud server is using more advanced clustering technology, in a group of similar multiple independent virtual server cluster server, each server in the cluster has a mirror of your cloud servers, thus greatly improving the safety stability of the virtual server, unless all the servers within the cluster problems, cloud server would not be able to access. Therefore, cloud server relative to VPS host and a higher level of stability, higher security.
Virtual host < VPS < cloud server
The above is the difference between them, I hope to help you.
