Fedora Linux vs. IBM AIX

For experimental use, test lab situations, or very special-purpose tasks, Fedora [Linux] is an excellent choice. We are almost exclusively a CentOS shop for our production stuff, but in labs, we take more risks with things like Ubuntu or Fedora. It's not as appropriate as CentOS for production level endeavors, but it lets us know "this is where we could be going" when we engage in r&d tasks.

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.

• Better cutting-edge software packages than RHEL/CentOS
• Better for an R&D platform than other systems
• Combines the stability of RHEL/CentOS-style systems with more experimental software

Incentivized

• The newer version of IBM AIX allows to apply new patches without system restart
• IBM AIX was the first operating system to have a journaling file system and have enhanced software features.
• IBM AIX will have good vendor support 24/7 and will ensure reliability to the customers and more performance when compared to it peers.

• Stability. It's good, but it's not anything like CentOS for stability
• End-user usability. It has a few glaring holes here and there with UI/UX

Incentivized

• 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.

We are an all-CentOS-shop, but we've done a number of things with Ubuntu and Fedora. Most of the production CentOS machines are only there because prior to that Fedora helped to blaze the trail to get there. It's been a very good platform for testing our new ideas. Ubuntu is similarly positioned in our organization, but Fedora stacks up well in our environment.

Incentivized

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.

Incentivized

• It's been mostly positive. We don't spend a lot on R&D stuff, but Fedora [Linux] gives us a chance to gauge where we are at in comparison to where technology is headed

Incentivized

• 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
