Indistinctively of having subscribed to a free web hosting plan or an unlimited one, the sort of web hosting service that you have is named Shared Hosting. With this plan, you and other users have a share in storage on a web server. As the expenses of web hosting services are also partaken by all the users, the web hosting providers are able to offer rather reasonable fees for their services. Nevertheless, all the files that are on a same shared server are exposed to all users. Meaning that, if one of them commits a mistake in scripting, all the other servers are afflicted. As a result, and to reduce the chances of this occurring, all users subscribed to Share Hosting are unauthorized to run programs of their own.
More than once, business or experienced programmers have the necessity of running their programs. Given the case, they are conveyed with the possibility of renting a server (a Dedicated Server) for themselves. But, a service like this is around 100 dollars a month.
Virtual Private Servers (VPS) is an option for the ones who need to run customized programs without spending too much. Simply put, VPS users share the server with others, but they have aside computer functions. Rephrasing, files and hosted websites suffer no impact from other users on the server and each VPS is assured resources on the server (like secured 256MB ECC RAM of the web server). With this, the service provides better security and performance. In average, VPS costs around 20 dollars a month.
So, what do you choose between Shared Hosting and VPS Hosting?
For businesses in possession of a webmaster and/or for programmers with experience, VPS hosting is highly recommended since VPS users are in full control of the assigned servers. On the contrary, for users under a short budget, share hosting might be the best option.
