Linux is amongst the most widely used OSs for web servers. There are quite a few different distributions which use the exact same core, but the vast majority have a couple of things in common - they're absolutely free to use, which minimizes the total cost of the web hosting service as license fees will not be included in what you will need to pay; they're very easy to take care of; and last, but not least, they're significantly more secure in comparison with competitor OSs, as random files, particularly virus-infected ones, can't be executed on the web server. This way, you can enjoy a reliable service and spend the time building and promoting your web sites, not worrying about basic safety issues. Many Linux-based machines use the Apache server to manage the HTTP traffic, since this software is extremely fast and is also simple to maintain and individualize as per the requirements of the web hosting provider. A Linux hosting 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 apps nowadays require LAMP, that refers to Linux, Apache, MySQL and PHP.
