A VPS (Virtual Private Server) is a single virtual server/computer that is hosted on a physical server (generally known as a VPS Node). These VPS Nodes generally have large amounts of RAM and Space so that they can be divided up into multiple VPS.
Each VPS is allocated its own amount of RAM and Hard-drive space (and sometimes even CPU). Each VPS shares the VPS Node’s resources, but each VPS has its own allotment and operates independently like a normal server or computer would. Due to the way VPS’ operate, you can install your own software and OS without ever affecting the VPS Node or any other VPS’ on that Node.
In VPS hosting terms, the customer shares the, hardware, network and power with every other customer on that VPS Node. However, the benefits of a VPS over shared hosting are great! For example the have the following benefits:
- Have access to their own OS and File System
- Are always guaranteed their allocated RAM and Space
- Complete Administrative Tasks – changing server configurations, installing personal software.
- Rebooting and powering down their VPS 24/7
These benefits allow customers to have greater freedom and security. VPS are above shared hosting, but below dedicated hosting.
For those customers who are currently on a shared host, and are wanting to move over to a dedicated hosting environment without a great jump in overall costs should probably take use of VPS Hosting. When you use VPS, there is no need to be worried that anyone else can access your data as each VPS has its own operating and file system which is separated from every other customer on the VPS Node. VPS can be suitable for those who wish to host multiple small sites, or wish to host one single site which uses too many resources for shared hosting, or for those who wish to expand their skills from just shared hosting, up to server management without having large costs for a dedicated server.
