Linux is among the most popular OSs for web servers. There are several different distributions using the same core, but the great majority have a couple of things in common - they're totally free to use, which decreases the overall cost of the hosting service as license fees will not be included in what you have to pay; they're easy to maintain; and last, but not least, they are significantly more secure than competitor Operating Systems, as random files, especially virus-infected ones, can't be executed on the web server. That way, you can enjoy a secure service and spend the time creating and advertising your websites, not bothering with safety issues. Many Linux-based machines use the Apache web server to deal with the HTTP traffic, as this software is incredibly quick and is also very easy to maintain and customize as per the needs of the hosting provider. A Linux web server with Apache is the perfect software environment for your sites and it isn't a coincidence that a lot of popular script-driven apps on the market require LAMP, which stands for Linux, Apache, MySQL and PHP.
