There are many types of Managed Semi-VPS hosting available. However, UNIX/Linux and Windows hosting dominate them all. The type of hosting you select will completely depend on what technology your website will use. For example, websites should use UNIX/Linux-based platforms if they are utilizing PHP programming and MySQL database (like many Open-Source CMS). Similarly, websites that use ColdFusion, IIS, VBScript, Windows Media, ASP or .NET programming, MySQL database, or other Microsoft solutions like Frontpage, should utilize Windows hosting. Currently, we are only offering Linux hosting in our Managed Semi-VPS hosting packages.
