Linux hosting and Windows hosting are the two most popular operating systems for any type of hosting (i.e. shared, a dedicated server, a VPS, etc.) and frequently there is a debate if Linux hosting or Windows hosting is better. To some extent the debate is fueled by the fact that Linux hosting uses open source software to provide the hosting service, while Windows uses proprietary software.
In fact, the debate of Linux hosting versus Windows hosting is more of a debate “open source versus proprietary software” rather than which of the operating systems is the better hosting platform. Both Linux and Windows have their strengths and weaknesses as host operating systems and in many cases what can be considered a strength quickly turns into a weakness - i.e. as a rule Linux is more secure, but if the admin is inexperienced and doesn't know how to configure security properly, a Linux server can be a real security disaster.
