That will always depend ... you'll find that companies where there's
some financial risk involved will commonly choose a commercially
supported distribution like RedHat or SuSE; preparing yourself for
those will require Centos or OpenSuSE ... other companies will choose
whatever their admin staff are most familiar with, or admins for
which appear to be easily sourced.

CentOS is great server operating system. If You are RHCE then You will be very familiar with it because it is based on RedHat Enterprise Linux source and is 100% compatible with it.

If system is mission critical then usually use commercial supported OS - SUSE Linux Enterprise Server or RedHat Enterprise Linux. Commercial Linux will provide faster updates and support will help to solve problems.

Ubuntu is interesting player in market and after some time could be very strong. They doesn't separate commercial and community/free versions (RedHat has Fedora, SUSE has OpenSUSE). If You need support - just start paying. Problem is that it haven't software and hardware certification in required level.

For example, if You will buy HP server then You can be sure that it would work with RedHat and Novell SUSE flawlessly. Lot of commercial software do the same (for example Lotus Domino/Notes) Ubuntu Server haven't such advantage yet.

I'm not expert in Linux desktop market (my desktops are running winXP, sorry ), but Ubuntu is looking better than RedHat and Novell there.

I am working in Telecom sector I haven't seen any single Windows server at my production environment all are Linux and Unix but our Mail server, DNS server and Active directory are Windows servers so as Tinkster said, It's depend on the needs.

No -

You should stop worrying about "buzzwords" and certifications, and try to get as much *practical*, *hands on* experience as you can!

Don't go jumping around from OS to OS: just learn more about the OS you've already installed. "Learning how to learn" is FAR more important than having a "bullet" to put on your C.V.

We use vxworks, QNX, MS, Red Hat, IRIX, Suse, Novell, VMS and OpenVMS, MacOS, and some one of a kind industrial OS's.

You may need to expand your horizons. Almost every production plant I have seen uses any number of systems that may range from modern to antique and include common to obscure.
