Linux is among the most popular OSs for web servers. There are tens of different distributions that use exactly the same core, but the majority have a number of things in common - they're 100 % free to use, which decreases the overall cost of the website hosting service due to the fact that license fees shall not be included in what you will need to pay; they're quite simple to maintain; and last, but not least, they are way more secure in comparison with competitor OSs, since random files, especially virus-infected ones, simply can't be executed on the hosting server. That way, you can enjoy a secure service and spend the time developing and advertising your web sites, not worrying about safety issues. Loads of Linux-based machines use the Apache web server to handle the HTTP traffic, since this piece of software is really fast and is also very easy to maintain and individualize as per the needs of the hosting provider. A Linux web server with Apache is the most suitable software environment for your sites and it isn't a coincidence that a lot of popular script-driven applications out there require LAMP, that stands for Linux, Apache, MySQL and PHP.
