If you get your own hosting server, you shall have more flexibility in regards to what you can install and run when compared with a shared Internet hosting account. With a shared service, you've got access only to your own account, thus you aren't able to install server-side software. Even though this is not an issue for the majority of script-driven apps, there are some which have specific requirements and need particular software to be present on the server either for some additional features or for them to work at all. In case you have practical experience, you won't have any problems to run the server, but if you don't, you may simply not have the knowledge to deal with everything and use the script applications you want. If that's the case, you'll be able to use our Installation & Troubleshooting upgrade, so our system admins can set up everything for you and help you with any issues that you could encounter.
