A main virtual server or a virtual private server (VPS) is one of the most common and widely used solutions for web hosting. A virtual private server enables multiple virtual servers to run on only one server. In VPS hosting, the hardware is controlled by the web host provider but the software and operating system are under the control of the owner of the website.
There are many advantages of using a main virtual server. One of the advantages of VPS is it enables every virtual server to have its own operating system and domain-related software installed. Each vps is isolated from another virtual server, meaning that even if one server crashes the other servers will not be affected.
Each VPS also has its own allocation of disk space and CPU memory. This enhancements the performance of the virtual servers and stealing of other virtual server's allocated space and memory is not possible.
In terms of security, a main virtual server can be advantageous since each website runs using its own operating system. This makes it harder for other virtual private servers to get past the security measures of the VPS. Main virtual servers also provide mail and traffic security as well.
While there are many advantages of using a virtual private server, there are disadvantages as well. For one thing, maintenance can be a bit of a problem since each virtual server has its own operating system. You have to update, maintain, and patch each server separately due to different operating systems. It can be time consuming as you have to attend updating, security issues, patches, and installation of each virtual server.
Since the disk space and memory is allocated to each specific server, it can be difficult to handle large traffic on the website since it is limited. This can affect the speed of delivery of a website.
Using a main virtual server has its own pros and cons. It would be a good idea to weigh the advantages against the disadvantages to determine if this web hosting solution is best for you or not.
