1. Oracle
It’s one of the biggest and most popular companies that offer informatics products and services, it uses Linux and also it has its own Linux distribution called “Oracle Linux”.Oracle is one of my favorites enterprises because it has excellent products like databases, java, virtualization software, operating systems and more. Oracle offers two operating systems: Oracle Solaris and Oracle Linux, if you want to try its Linux distro you can get an Oracle account for free and then download the ISO file to install the system, but you should check the requirements because Oracle Linux can not be installed on all computers.

Novell offers its own Linux distro: SUSE Linux.SUSE Linux: Distro Review Of The Week SUSE Linux is one of the most important distributions because there are a lot of companies that use it.

There are many people that know that Linux is the leader talking about operating systems that make the web works, and Google is a great part of the web, in my opinion, Google is the web for most users.

I meet a lot of people that know nothing about Linux, but all the people are using Linux thanks to Google.

It is one of the most popular social networks, created by Mark Zuckerberg Facebook is, in my opinion, the best social network of the moment because it has too many characteristics that are very useful.If you scan the facebook web address using nmap or another tool you will see that it is using Linux. I’m happy because Facebook’s servers are powered by Linux because it demonstrates that Linux is a good choice to use on a web server. Linux has the power to keep stability even with excessive information.

I know that it is incredible but it’s true, Microsoft loves Linux and is using it. For example, Microsoft Azure offers virtual machines with Linux and also it offers virtual containers with Docker. If you thought that Microsoft hated Linux, you were wrong. I’ve heard that recently Microsoft joined Linux Foundation and now it is a platinum member.
