Linux is among the most widely used Operating Systems for servers. There are a number of different distributions which use the same core, but the vast majority have a few things in common - they are absolutely free to use, which decreases the total cost of the hosting service as license fees shall not be included in what you will have to pay; they're quite simple to manage; and last, but not least, they're way more secure in comparison with competitor OSs, as random files, especially virus-infected ones, just cannot be executed on the server. Thus, you can enjoy a reliable service and spend the time building and promoting your web sites, not bothering with basic safety issues. A lot of Linux-based machines use the Apache server to deal with the HTTP traffic, as this software system is incredibly fast and is also effortless to maintain and customize as per the requirements of the web hosting provider. A Linux web server with Apache is the most suitable software environment for your websites and it's not a coincidence that lots of popular script-driven apps available on the market require LAMP, that stands for Linux, Apache, MySQL and PHP.
