Other than hosting resource-demanding sites, there is a further reason to purchase a virtual or a dedicated server for yourself - to make your hosting company. This is an ever-growing business, because more and more people and businesses start their world wide web presence, so they need website hosting space and a domain name. If you have a website hosting server, you can make hosting offers and then sell them, so you can not only cover your own expenses in case you host your own sites on the server as well, but you can also make a decent profit by having a profitable business. What you need for that is a server, a billing program, which will be the link between the reseller site and your web space, plus a business account with a payment processor for instance PayPal or 2CheckOut, in order to be able to receive web payments. The advantage of reselling server space over the usage of a standard reseller program is that your clients will have a lot more resources and you are able to install the server-side software that their sites may need so as to work effectively. The latter isn't possible with a shared hosting reseller program, since you will have certain restrictions in this regard.
