When you get your own server, you shall have more freedom as to what you could install and run compared to a shared Internet hosting account. With a shared service, you have access just to your own account, so you're not able to install server-side software. While this is not an issue for the majority of script-driven apps, there are some which have certain requirements and need particular software to be present on the web server either for some additional features or for them to work at all. In the event that you have experience, you'll not have any problems to run the machine, but if you do not, you may simply not have the skills to deal with everything and use the script apps you want. If this is the case, you could use our Installation & Troubleshooting upgrade, and so our system administrators can set up everything for you and aid you with any difficulties that you might come across.
