Linux is among the most widely used Operating Systems for servers. There are many different distributions using exactly the same core, but the vast majority have several things in common - they're 100 % free to use, which decreases the overall cost of the web hosting service because license fees won't be included in what you'll have to pay; they're very easy to maintain; and last, but not least, they are much more secure as compared with competitor Operating Systems, as random files, specifically virus-infected ones, just can't be executed on the hosting server. In this way, you are able to enjoy a secure service and spend the time creating and advertising your websites, not worrying about security issues. A lot of Linux-based machines use the Apache server to deal with the HTTP traffic, due to the fact that this software is extremely quick and is also effortless to maintain and customize depending on the requirements of the web hosting provider. A Linux web server with Apache is the ideal software environment for your websites and it's not at all a coincidence that a lot of popular script-driven apps out there require LAMP, that signifies Linux, Apache, MySQL and PHP.
