These days the term virtual server has grow to be widespread in the online hosting world. This is definitely not a completely new technology, as the idea has been around since at least the 1980’s, produced by the big computing companies at the time on the Unix system (IBM, DEC, etc.).
Virtual server software (also known as a VDS software), is actually a technology that splits real computing components into several virtual hardware containers which each run their own OS, separate from each other. These virtual private servers can be used for many purposes including:
- Optimising hardware resource utilisation
- Running groups of lower intensity programs
- Providing hardware independent hosting platforms
- Roaming computer’s desktop replacement
There are numerous virtual server technologies currently available, including:
Each of them have their particular pros and cons, however essentially perform a similar function, which is to create a virtual hardware environment as a way to run an independent OS.
Lots of hosting providers offer you virtual hosting solutions as a way to eliminate the need for clients to deploy any server hardware at all. Instead a client simply rents a virtual machine within the hosting company’s facilities and so removes the need to buy any hardware whatsoever. In these hard economic times we are seeing more and more people turning to VPS as a means to deliver their online services. The need to not deploy physical servers for many people has been a huge benefit in terms of saving time and money.
In addition, the use of a virtualised server often leads to increased uptime for the client, as they are less affected by hardware failures. Most VPS virtual server hosting companies will be able to move the VPS to another physical server in the event of a hardware failure occurring on the server physical server currently hosting your VPS.
