If you obtain your own server, you shall have more independence on what you'll be able to install and run compared to a shared hosting account. With a shared service, you've got access just to your own account, so you're not able to install server-side software. Although this is not an issue for most script-driven programs, there are a few which have certain requirements and need certain software to be present on the hosting server either for some additional functions or for them to work at all. In case you have experience, you won't have any difficulties to run the machine, but if you don't, you may simply not have the skills to handle everything and use the script apps that you want. If that is the case, you are able to use our Installation & Troubleshooting upgrade, and so our system admins can setup everything for you and help you with any difficulties that you could face.
