Linux Flavour

 Following are the most common Linux Distribution in used
==============================
1. Ubuntu

My personal favorite was Ubuntu for desktop (#1 in this list) and Red Hat for servers (#5 in this list).

If you are new to any of the distros listed in the top 5, read the rest of the article to understand little bit more about those distros and find out whether your favorite Linux distribution made it in the top 5.

2. Debian

Debian is also called as Debian GNU/Linux, as most of the basic OS tools comes from the GNU Project. Lot of other famous distributions are based on Debian, which includes our #1 distro Ubuntu and many others — such as Knoppix, Linspire, Damn Small Linux etc.,

3. Fedora

Fedora is sponsored by Red Hat. If you are interested in experimenting with the the leading technologies, you should use fedora, as the release cycle is very short and fedora tends to include the latest technology software/packages in it’s distribution.

4. CentOS

If your organization does not want to spend money on purchasing Red Hat support, but still want all the benefits of the red-hat distribution, this is obviously the best choice, as this is totally based on the red-hat enterprise Linux.

As you can imagine the Nort American Enterprise Linux vendor mentioned in the quote below is Red Hat.

5. Red Hat

This is my favorite server distribution.  If an organization doesn’t mind spending dollars on purchasing the red-hat support, this is always my #1 recommendation to any organization who runs mission critical applications.

On a side note, one of the reason I like Red Hat Linux for mission critical production application is that Red Hat tends to take some of the new features from Fedora, which is well tested by the community.
