Linux is among the frequently used OSs for servers. There are several different distributions using the same core, but the vast majority have several things in common - they're free to use, which minimizes the total cost of the website hosting service since license fees will not be included in what you'll have to pay; they're easy to manage; and last, but not least, they're way more secure as compared with competitor Operating Systems, since random files, particularly virus-infected ones, just can't be executed on the hosting server. Thus, you will be able to enjoy a protected service and spend the time building and promoting your websites, not bothering with security issues. Many Linux-based machines use the Apache server to manage the HTTP traffic, because this software is very fast and is also simple to maintain and customize in accordance with the needs of the website hosting provider. A Linux web server with Apache is the most suitable software environment for your sites and it's not a coincidence that lots of popular script-driven apps nowadays require LAMP, that symbolizes Linux, Apache, MySQL and PHP.
