Key Benefits of Virtual Private Servers (VPS)

Virtual Private Servers are a core technology that are now used globally by hundreds-of-thousands of companies. This short article will give you the run down on what a VPS is, and why they play such an important role in the computing world.

What is a Virtual Private Server (VPS)

A virtual private server is a dedicated machine designed to run multiple copies of an operating system, be it Linux, windows or any other x86 compatible system, in an isolated and safe manor. Usually the phrase VPS is reserved for talking about the operating system that is running on the host machine and is the phrase you will come across most often.

The VPS system was designed to replace the need for multiple, power hungry, dedicated physical servers. Using a virtual system to run many instances of an operating system all on one machine means that the TPD (total power draw) is considerably lower than using physical machines and keeps hosting costs down. The main goal was to create a system that would allow the same interaction as DPS’ but with none of the constraints and in some cases actually be easier to configure and create.

Using this system a user is able to perform all tasks you would expect from a normal functioning PC. If a standard computer can run your program, so can the VPS. In many aspects this is great functionality, but performance may suffer. The VPS can only be as fast as its host machine and processing time is often shared between multiple instances. For everyday tasks this is not a problem, issues generally only start to occur when running specialised applications that require large amounts of processing power. In these cases, however, the VPS can be assigned more memory/CPU cycles to perform tasks at a more appropriate rate.

Using this flexible system of performance scaling, customers are able to choose the most appropriate price point for them, whether they are looking for a low cost “always on” machine to constantly perform a routine task or a powerful machine to run specialised, power hungry, software; there is always a solution to suit.

With the new age of cloud computing, comes dynamic resource allocation. This utility has been around for many years in highly advance corporations but was usually reserved for dedicated machines that would perform one complex task at a time, in multiple instances. DRA allows a VPS host to actively and automatically adjust how much computing power a client is getting, on the fly. This means that if one machine is idle, it’s allocated CPU and RAM can be used elsewhere to help perform more power intensive tasks. This new method of dynamic resource allocation has opened new pathways on how VPS companies can price their products. By using market research and in-depth analysis, hosting companies can create price packages that offer a lot of power, for very little money. In the past this would cause a large problem because each VPS would have to be restarted to re-allocate blocks of CPU or RAM time. Now, however, this is done on the fly without the user ever having to interact with external software.

We have talked in depth about what a VPS is and does, but have not yet spoken about why you would choose to use one. Using a virtual private server is an excellent way to save money, and physical space, when needing to run applications that do not depend on local hardware. VPS also provide a high level of security from: Virus’, Malware, Spam and malicious attacks. A virtual private server is able to offer such security for a number of reasons:

  • The VPS is hosted away from the clients base of operations
  • The connection to the VPS can be encrypted with any type of suitable encryption
  • A VPS can have a dynamic IP address while remaining accessible through a portal
  • VPS software is separated from all other software through virtualisation

In summary, a VPS would be a perfect choice for any company or individual that needs a low cost solution to powerful computing. There are thousands of applications that a VPS can suit and with new cloud computing technology the number of applications will continue to grow. Not only will support for software never be an issue (a VPS will run any software that runs of a physical machine) but nor will your security. In a time when internet security is of more importance than ever, the VPS is here to stay. Offering up a fantastic solution, to an age old problem.
