IBM

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.

Red Hat

[ Red Hat Enterprise Linux] (RHEL) is a great suite for almost everything Linux and has a great ecosystem free Open Source of third party repositories to find what is not provided by default. ... an environment where 24x7 support is required, their support level is awesome, environments with a lot of vendor dependent applications, since almost all of them build their apps for [ Red Hat Enterprise Linux] (RHEL). [ Red Hat Enterprise Linux] (RHEL) could improve: SAP environments, I've compared its integration levels to other Linux vendors and it could be better. Mainframe (390) solutions. Although [ Red Hat Enterprise Linux] (RHEL) support for System Z is great, I believe SUSE's is better.

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!

Red Hat

  • We were hoping to deploy Red Hat Certificate Services but even after professional consulting with Red Hat, we weren't able to integrate it into our Microsoft environment due to the inability of performing workstation auto-enrollment.
  • The license renewal/support costs appear to rival those of other operating system providers which makes you wonder about the added value you are expecting.
  • Hardware compatibility can be a little restrictive if you are using lesser known non-mainstream specialized products.

      RHEL has most of the features that are required by an ERP solution. If you need any additional packages, RHEL has a great repository and a very easy package installation/upgrade process.

      Alternatives Considered

      IBM

      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.

      Red Hat

      While the other flavors of Linux listed above can be used to achieve similar goals, RHEL was chosen due to: 1. Excellent support, both professional and through the community 2. Tried and tested security 3. Its Binary compatibility with Cent OS is a major plus as it allows a test environment to be built without additional licensing

      Return on Investment

      IBM

      • 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

      Red Hat

      • Overall, RHEL has helped us achieve heights in performance management and handling a large crowd at once with its huge management capacities. It is highly reliable and if used with apt load balancers you will not require more than one backup server because the crash frequency is minimal.
      • No negative impacted has been faced as of now since using RHEL.
