If you acquire your own server, you will have more flexibility as to what you can install and run compared to a shared Internet hosting account. With a shared service, you've got access only to your own account, hence you are not able to install server-side software. While this is not a concern for most script-driven applications, there are several which have particular requirements and need particular software to be present on the hosting server either for some additional functionality or for them to work at all. If you have experience, you will not have any issues to run the server, but if you don't, you may simply not have the knowledge to handle everything and use the script apps that you want. If that's the case, you'll be able to use our Installation & Troubleshooting upgrade, which means that our system admins can set up everything for you and help you with any difficulties that you might encounter.
