Flavor of Unix

I would like to know wich Unix to get and run, because I have access to "ALL" paid and non paid versions

What I would like to do is set up Cloud Computing from home so that I may gain experience in this area for my resume. I have read that the best right now is Ubuntu Server v9.10

Can anyone tell me about this or is there a better option?

I am open to Solaris,IRIX,Free BSD,Open BSD,Linux,Mandrake,Corel Linux Delus,Fedora,Ubuntu Server,RedHat Enterprise, ETC..

If it helps I would like it to also run on a desktop or a mainframe as seen in the tv show Level 9 :slight_smile:

Red Hat (the company) has been particularly active in the area of cloud computing, so you may want to try that distribution as well. It must be said however that cloud computing is not something someone new to Linux and UNIX should start out with, since it still requires considerable expertise to set up and maintain. I do encourage you to try it.
