Have you ever wished that you could just host your own web sites rather then relying on the software a 3rd party host uses? Want to be in more control of the features your hosting can handle, install new and different scripting languages, host multiple websites under one system, and not be limited by the hosting company’s cPanel anymore? Then perhaps a Virtual Private Server system is right for you.
A VPS is meant so that people can be in more control of their hosting, without having to pay to rent out an entire machine. If you’ve ever used an emulator before, a VPS works the same way. A computer emulates hardware using some type of software, and one powerful computer can then become many slightly slower ones. Using a remote desktop connection, customers can connect to these emulated computers and modify whatever they want about them as if the machine was their own, without the risk of damaging any of the other systems.
But VPS is not meant for everyone. If all you need to do is run a blog, share some photos, or host a forum, then a VPS is probably above and beyond what you need. Below we’ll discuss the specific instances in which a VPS becomes necessary.
The most common use for a VPS system is for the webmaster who runs many sites. Wouldn’t it be nice if you could run them all using the same machine? Since a VPS gives one access to a file system and allows the advanced webmaster to upload and run their own programs to constantly run, things like performing repetitive tasks across multiple sites can be done with ease. Jobs that used to take hours, such as starting 10 blogs and having to upload, install, and configure WordPress (not to mention all those add-ons) becomes as simple as copying and pasting. SQL databases can be managed in a similar way as well. Not to mention you aren’t only limited to using one type of database, but any kind you want. Heck, you could design your own database system and use that too.
A VPS is in fact absolutely necessary for anyone who wants to develop their own server-side scripting languages and database management systems. Since you have full access to change, modify, or add on to the software that your server uses, you could upload your own programs to let the server understand these languages. There’s always new useful scripting languages being developed on the open-source sites, but to be able to run any of them a server must be used and configured properly from the system‘s end. Having a VPS is very handy when you don’t want your websites to be limited by the functions PHP can perform.
Finally, VPS can be useful where downtime is absolutely unacceptable. For servers that need to complete repetitive processes every time on time, a VPS can be more reliable than a shared system. VPS servers don’t go down for regular maintenance by the hosting company, nor do they go down due to some other webmaster causing an error in the server. The time in which the computer’s processor is used to perform takes is fairly divided between all VPS programs. This way, no one webmaster can try and eat up all of the machine’s resources and slow everyone else down.
