It is a common practice among web hosting companies today, to offer hosting packages, with unlimited features. This is valid especially for shared web hosting packages. However, for the normal internet user, who isn’t familiar with the technical side of the web hosting service, it may come as a bit of a shock, when the hosting company suspends his “unlimited” web hosting account, because of overloading the web server. In fact, there is no such thing as unlimited feature, except for the number of hosted domains slots, in the field of the web hosting services. To better understand this, let us take a look at

How does web hosting work?
Web hosting basically means web server space. A web server is nothing more than a computer, with a bigger processor, RAM slots, network card and hard drives. All of those three, however, have a certain amount of bytes. At this moment, computer science has not yet reached the level of perfection, required to create a hard drive, which can store an unlimited amount of information. Therefore, each web server has a certain amount of physical memory and processor capabilities. And since the server’s hard drive is not unlimited, there is no possible way, for an account on that server, to have unlimited disk space. However, some of the web hosting providers are using the users low level of technical knowledge, in order to lure them towards their web hosting packages. Today, this is a common practice and almost all of the web hosting providers are offering “Unlimited” hosting features, for their shared hosting packages, in order to keep up with the competition. It is true, however that some of the big hosting providers, are indeed making sure that their clients are using the most server resources possible, by taking the “unlimited” features policy and making it into the thing called Overselling.

How does overselling work and where can it be applied into?
Overselling means, of course, selling more that you actually have, however, it also means that you’re doing that in a controlled and adequate manner. The biggest web hosting companies, who have the resources and the ability to do that, divide their web servers into accounts, who are distributed to users from different time zones. By doing so, the users from one side of the world, can use the most server resources, while the users from other side of the planet, are sleeping. The servers are also maintained and monitored 24/7, in order to assure that none of the accounts are putting their peers in danger, by overloading the server. Because of the nature of the shared hosting service, overselling can only be applied on shared web hosting accounts. Users who sign up for dedicated servers and Virtual Private Servers, can actually see what their actual account specifications are, therefore, overselling will be kind of pointless in such cases. And the fact that VPS and dedicated hosting servers cannot be oversold is only one of the many differences between the shared hosting and the private hosting services. To see what the other differences are, let’s take a look at

What a private server is?
A private server is a machine, which is dedicated to only one user. When this one user, is the only one who has root access to the web server, this means that he has complete control over its features and operating system configuration. This of course means that tons of possibilities are opened to the root user, all of which are unavailable on shared hosting accounts. For instance, with root access, the user can install, change and update practically everything that is compatible with the server’s attributes and in web hosting, even the smallest change in configuration of the software installed, can make a huge impact on the performance and the functionality of the hosted websites. Whether it will be e-mail sending, web site functionality, Google search engine optimizations, everything can work better and in higher quantities, if the right changes are made to the web server. And with the introduction of the virtual private hosting, such services are now quite affordable even for the users who are on a more ‘tight’ budget. For instance, there are many hosting providers  offer VPS hosting accounts, ranging from 25 USD/month to 70 USD/month, where a physical dedicated server can range from 100 USD to 1 000 USD/month, depending on the configuration and the provider. Therefore, if you do care for your web site’s performance and security and you do wish your web site to have that one little thing that makes the difference, then the virtual hosting is definitely the recommended service for you.
