Introduction
Linux is used in most servers for many services, such as web servers, contents hosting, database servers, FTP servers, telecom servers such as PBX, load balancer, firewall and router, yes Linux can turn PCs and servers into routers and firewalls instead of buying hardware appliances.
Currently more than 90% of internet servers are Linux according to many statistics, and top sites on the Internet are using Linux.
As a free OS, we can install Linux as much as we need in virtual machines, cloud servers, new PCs, old PCs, physical servers, single board computers, for testing, for production, for commercial, non-chimerical, and for academic institutes.
