FreeBSD is an excellent choice to continue using older hardware and have it perform, it is a great choice for a UNIX based development environment. Although I haven't used it as a server, it is most suited for this - it would make an excellent, secure and robust server for and I would love to start using it for this as well.

IBM AIX is a very powerful and extremely stable operating environment. It is well suited for applications that are business critical and cannot tolerate outages. It is best used to address large enterprise level application needs where stability and scalability are of paramount importance. IBM AIX is less useful for small enterprises.

  • A lot of the built-in commands have not been updated in years. If you're used to some fancy CLI options in Linux, you may be out of luck with AIX.
  • Out of the box, you cannot run open-source Linux utilities on AIX. There is a toolbox you can install, however, it's not the same versions as you would get in different Linux flavors.
  • Tab completion for files and Up arrow to re-run previous commands don't work out of the box without running a Korn shell. A small annoyance, but one that catches me every time!

There is lots of documentation out there for AIX. On the times I've had to address a hardware issue, IBM's support has been great.

FreeBSD is the closest to the original BSD unix. This OS is currently used by vendors in the field of routing, switching, security as well as base OS for MAC devies.

Standard Linux distributions which are used more as commodity servers do not offer the ease of scale and growth that we see with our Aix implementations. IBM owning the HW and SW portions of the stack allows for tighter integrations and better performance windows.

Return on Investment
Open Source
  • As FreeBSD is free - the ROI is at least the cost of some commercial Linux or Windows based OS (which can be very expensive)
  • Allowed the re-use of older hardware that would have otherwise been disposed
  • No cost development environment
  • Opportunity for a no cost server setup also

  • IBM AIX on Power hardware has been the backbone of our most critical applications.
  • The versatility of IBM AIX virtualization has been extremely useful, scalable, and provided configuration with redundant dual VIO servers.
  • IBM AIX is not Linux so special skill sets are needed to actually manage the systems. Finding qualified engineers can often be a challenge
