Linux is amongst the most widely used Operating Systems for web servers. There are many different distributions using exactly the same core, but the greater part have a number of things in common - they are 100 % free to use, which cuts down the total cost of the web hosting service because license fees will not be included in what you will have to pay; they're very easy to manage; and last, but not least, they are a lot more secure as compared with competitor OSs, since random files, specifically virus-infected ones, simply can't be executed on the web server. In this way, you can enjoy a protected service and spend the time developing and advertising your web sites, not bothering with security issues. Many Linux-based machines use the Apache web server to deal with the HTTP traffic, since this piece of software is really quick and is also very easy to maintain and individualize as per the requirements of the hosting provider. A Linux server with Apache is the ideal software environment for your websites and it's not a coincidence that a lot of popular script-driven apps these days require LAMP, that refers to Linux, Apache, MySQL and PHP.
