VPS (Virtual Private Server) technique separates a large physical server into several dedicated virtual server through virtualization.
Each virtual server has its own IP address, operating system, hard disk, RAM, CPU, customized system configuration and so on. On the other hand, virtual server can also be used as physical server to perform the operations like software installation and rebooting.
Background
The shortcoming of Virtual Web Hosting is that the users share all resources of the host. When some user overuses the resource, other users may be affected due to the overburden. Although the performance of a dedicated physical server is satisfying, the maintenance fee of such equipment is comparatively expensive. Therefore, it may not be a wise choice of small projects.
VPS technique separates a large physical server into several dedicated virtual server so that every virtual server has its own operating environment and get balance from sharing the resource. The virtual server can perform as a physical server as it has its own operating system
and IP address while the full control can be obtained. Moreover, as the virtual servers are isolated, they will not be affected by each other.
Features

Advantage of dedicated IP address

2. Promotion Advantage. When a dedicated IP address is used for a website, search engine will consider it as a dedicated website service so that the possibility of being recorded will be increased.
3. Data Confidentiality. SSL protocol can be utilized for a dedicated IP address to provide a better security so that the data will less likely be lost. Such protocol is widely used on different kinds of payment platform.
4. WildCard DNS record. It’s possible that the website cannot be accessed due to a typo made by the user. Such issue can be solved by using the WildCard DNS record if a dedicated IP address is used in your server so that the website traffic can be increased.
5. Direct Access. When dedicate IP address is used for a website, users can use the IP address to visit the website instead of using the domain name.
