Different flavours of Unix

vincente · #1 (**permalink**) 05-25-2006

Hi all,

I would like to know why is there so many different kind of unix systems like IBM AIX, SUN Solaris and so on..

What are the issues that we would considering choosing a Unix system?

Newbie to Unix, thus this question

Short answer: early versions of unix were free from Bell Labs, universities added features - BSD comes from Berkley.

You should worry A LOT more about:
1. What hardware platforms are supported by a given flavor of unix ? -
do you need one high end box or several servers.
2. Software costs
3. Contract/maintenance costs

The spectrum on this sort of goes from Linux .. Red Hat Linux ... Solaris ... HPUX and AIX

....in terms of cost and hardware. You can cluster some Unixes making a "big" machine out of smaller ones. We have four HPUX boxes, 137 Intel PC RH Linux boxes for 2000 users.

Are you saying that AIX supports more hardware than linux, or just that it costs more?
