Virtual Private Servers (VPS) have been used by many for quiet some time, but nowadays they are gaining popularity due to the newer software like FreeVPS, Xen etc. Before buying a VPS, you need to know what is so special about this server and how it works. Just read on to know more.

VPS is a single physical server which is split into several virtual servers. That is, the single virtual server is portioned in such a technique that the sole server appears to be multiple servers. VPS are ideal for those who want something different from the dedicated or shared hosting. Individuals and businesses often look for a VPS as it gives them some customization and privacy than a shared server. But, VPS is not as costly as a dedicated server.

Shared hosting is a good option to consider. But, the minimum available disk space, and the bandwidth and your site’s CPU being affected by other sites hosted from the same server are the main problems you may face with shared hosting. If your site is relatively small, then you may not worry about these things, though you may not have control over things such as scripts and system software in shared hosting.

Virtual Private Server is divided into ‘virtual machines’ with the help of the software operational on the server. However, some resources of the server like disk space, RAM etc. are still shared whereas the VPS gets its own share and functions completely unaided from the others. This independence allows you to run software and scripts or even installation of a different operating system without affecting the other virtual servers running on the same machine.

The main advantage of a VPS is the root level access you get with your server. You can delete or install software that you need and you can create accounts on your own. You can set permissions in the way you like effectively, and all these things that can be done with a dedicated server can be done in a VPS without huge payments.

In a shared web hosting all the websites are functioning with the similar operating system. So, when the server gets hacked, the sites sharing the server will also get affected. But, in virtual private servers this can be avoided since even if one of the portions gets hacked, the other portions will not be visible to the hacker.

VPS can be arranged in numerous ways so you should be aware of the number of portions it was divided by the web hosting provider. In most of the cases, the server’s whole resources are divided evenly by the number of virtual private servers on the machine. For example, if there are 5 virtual servers, then the total RAM, disk space etc. is divided by 5 and every VPS gets 20% of the total. So, inquire these basic details before getting a virtual private server. Then only you can enjoy the freedom that the VPS is providing and can make good use of it.

While Virtual Private Servers (VPS) have long been common place in the computer mainframe sector of computing, they are starting to re-emerge as a new attraction in the internet hosting industry. In simple terms a VPS system allows the host to “separate” off one server into a number of accounts – which basically act like servers within a server. Nothing new in this you may think?

Well, the beauty of this type of hosting is that each sub-server is able to hold its own operating system (allowing different users to use different operating systems on the same main server) and perhaps more importantly each virtual server can be carry out any transactions independently of the others on the physical server, e.g. rebooting, etc.

The emergence of this style of hosting has been encouraged of late by new virtualisation software, which allows each sub-server to act independently of all of the others. Not only does this offer a useful service to website owners, it allows hosting companies to fully utilise any space they have on their servers. The fact that they are able to run at full capacity reduces both the cost to the host, and ultimately the cost to the client.

VPS hosting is a useful hybrid between shared web hosting and dedicated hosting services, allowing the freedom of choice at a fraction of the cost of an individual physical server. You may find that certain hosts will actually put some restrictions on what can and cannot be added to VPS host accounts, but in the main they are proving very useful and very cost effective.
