When you obtain your own server, you shall have more independence as to what you'll be able to install and run when compared with a shared hosting account. With a shared service, you have access only to your own account, hence you're not able to install server-side software. While this is not a concern for most script-driven applications, there are a few that have specific requirements and need certain software to be present on the web server either for some additional functions or for them to work at all. In case you have experience, you'll not have any issues to run the server, but if you do not, you may simply not have the skills to deal with everything and use the script applications you want. If that's the case, you could use our Installation & Troubleshooting upgrade, and so our system administrators can set up everything for you and help you with any issues that you might encounter.
