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.

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.

Cons
IBM
  • 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!

  • Needed more CASE tools like RDi on IBM i to be developed.
  • The webSphere-related hosting procedure needs to improvised for quick turnaround or setup.
  • Just like XML-into, JSON based parser will be helpful to deal with modern data sets.

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.
