Likelihood to Recommend

CentOS

For the same type of tasks/roles that I have been using, I would definitely recommend CentOS for my colleagues. 9 out of 10 because it is a very stable and secure solution, but for some different tasks, there are lots of other Linux OSes that could be a better fit. For example, RHEL sometimes has better support of software vendors. Or, Ubuntu-like systems are better for GUI and desktop experience.

IBM AIX

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.

Pros

CentOS

  • Built on the same source code as RHEL. Each version has been thoroughly tested and customizable.
  • CentOS provides a rock-solid basis for applications that rely on maximum uptime. This has helped our services to maintain excellent availability.
  • While commercial support contracts are available, the project has a huge following/community and is always willing to assist.

IBM AIX

  • IBM AIX is a very stable server product, and I can't recall a time when the server has crashed due to a hardware fault.
  • If you have legacy software that can't run on the new-fangled Linux flavors, AIX might be the way to go.
  • AIX has a host of built-in management tools that makes system configuration easy for a novice.

Cons

CentOS

  • CentOS is not a great desktop platform. Although some would disagree with that statement, I think that CentOS is better suited to life as a server.
  • Since CentOS is community-supported some software vendors will not officially support it because it isn't Red Hat.

IBM AIX

  • While there are options to install some standard Linux tools like Bash, they are not always easy to procure
  • Allowing easier flexibility in how some tools and CLI options work would make it easier for admins to float between operating systems.

Again, written documentation is excellent, even on the older versions. The support community is the best. It is comprehensive and I would say that it global because it transcends national boundaries. Also, you find all types of people using CentOS to do all sorts of things so you are bound to find someone to talk to if there are problems.

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.

Alternatives Considered

CentOS

For our development environment, we evaluated CentOS against Ubuntu and SLES, and actually did not end up picking CentOS, as our developers found it primitive compared to the niceties offered out of the box from Ubuntu. In addition, our developers found that Ubuntu had an extensive user community, meaning they could very easily find support if needed from user forums. At that point, CentOS was a non-starter and we didn't move forward.

IBM AIX

AIX is a more mature operating system than Linux and its stability reflects positively on this. Safe application handling and uptime are great positive features as well.
Windows is not even a choice on the availability front, and patching and there are huge concerns about security on the Windows platform.

Return on Investment

CentOS

  • CentOS has just been a positive impact on our company. We have a fast, secure and reliable web server that has the same standards as the Enterprise version of Red Hat.
  • The biggest positive for me personally working as a System Admin is that I don't have to do anything with this server on a daily basis. It does what it is supposed to do for us every single day. Once a month, I run "yum update" and see if there are any updates and install as needed.

IBM AIX

  • 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
