To start it off, there is the dedicated hosting service. This kind of hosting services is in fact very advantageous. It is the website owners who will determine the capacity of the bandwidth and storage they may need for their website. They have a server dedicated to run only their website without any interference from other websites possibly in existence. However, what is quite unfortunate about the dedicated server hosting is that it will most likely come with a price that may even cost an arm and a leg.
As a matter of fact, that is often the reason why there are quite a large number of website owners who turn away to the option of having a shared web hosting service. A shared web hosting service is commonly pretty cheap compared to the dedicated one. Better yet, shared hosting now even comes offering unlimited storage and bandwidth for those using it. With that being said, it seems that website owners will no longer have to worry about using up the storage for their website or about the limitations of visits to their website per month.
Well, unfortunately, it is not really that nice and simple. There is absolutely a catch in the unlimited offer in terms of a shared web hosting service. It is of utmost importance for website owners to keep in their mind that the service providers will have to protect their dedicated servers from overload problems. Therefore, the providers will still have to make restrictions in some forms.
Most of the time, unlimited shared hosting service providers will not allow a website owner to use over a certain limit, say 20%, of server system resources. Unfortunately, FTP, CGI scripts, PHP – all of which are essential in modern websites – and even HTTP can use more than the limit. Also, there are often some other restrictions such as the inability to use web crawler of whatsoever types. So, after all, unlimited shared hosting is not entirely unlimited.
