Can you please show me what LINUX OS should I use in order to fulfill all requirements described above. More I would like to know about the license related to that Linux OS and the fee asociated with it. The last question is where can I purchase (download) this Linux OS?

Please if you could send me an answer as soon as possible so I could carry on with the ordering of the OS that will do for my Server System.

Thank you very much in advance for your time and your effort.

Best regards
