IBM AIX is well suited for mission-critical applications, especially the ones that need to run on well-performing hardware and need less downtime. It is also perfect for applications that need a lot of CPU, because AIX scales well on the IBM POWER hardware, so adding additional CPU almost always generates higher performance/throughput. IBM AIX runs unmodified from the smallest IBM POWER machine (S1022, with 12 Power10 cores) to the biggest machine (E1080, with 240 Power10 cores). Because IBM POWER systems have very fast CPU’s, you typically need a lower number of CPU’s when compared to alternatives. This may bring a reduction in cost for software licensed per core. Unfortunately, not all software vendors port their software to IBM AIX, so sometimes you may have to run Linux on POWER, or skip the POWER platform altogether. But many vendors happily support AIX and POWER.
Macs, macOS, and the appropriate Mac applications really shine in ease of use. Specifically, the system's media-handling features are excellent. The developer frameworks (libraries) are excellent and provide easy programmatic access to the operating system's features. macOS is very stable and is built on a solid foundation of a Unix kernel. The Swift programming language is very approachable, and macOS supports many scripting and programming languages, opening up a wide variety of coding libraries.
Stability. In the 14 years that I have used the product, I cannot think of a single time that we had an OS level failure. It is rock solid. We have had systems that have been booted and run for literally years without interruption.
Virtualization. We run IBM AIX as LPARS on Power infrastructure. All of our AIX infrastructure is virtualized making it easy to scale as needed.
Their logical volume manager makes the task of managing storage very simple. It is feature complete and they have mitigated much of the complexity that usually is inherent in LVM implementations.
I have a love/hate relationship with Smit. It is their administrative interface. It is very powerful and very complete which is why I marked it as a pro. It is also a bit clunky and somewhat arcane in its interface but still usable.
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!
AIX is robust, helps the systems administrator, is built to prevent easily made mistakes. If you are used to other variants of Unix (in particularly Linux) there is no steep learning curve to get started with AIX. You need to learn the intricacies of the operating system, but that is true for any new operating system. AIX has built-in tools for almost anything you want and has the AIX Toolbox (on the web) for tools that are not included with AIX by default, but can be installed. Installation of AIX is modular, you can select with components and features you want to have installed. Installation of additional components (and usually also removal of installed components) is easy and straight-forward.
I'm sure I'm biased. I've been using a Mac for 30+ yrs. I am significantly more productive on a Mac than on any other platform. It comes down to some personal preference and familiarity, but I just think the interface is more intuitive and streamlined
macOS tends to be very reliable, and Apple distributes updates as needed to patch known vulnerabilities or issues. It is very seldom that a macOS-based system is unavailable, and if that happens, the cloud-based storage and identity management support make it very easy to slot in a loaner machine while the user's primary machine is repaired.
The Apple Silicon hardware allows macOS to perform very well, with rapid response. Local processing for Apple Intelligence-related items is quite fast, and the response is impressively complete. Our experience with integrations to other enterprise systems is that the other system is usually the bottleneck in the process, rather than macOS.
IBM AIX operating system is advanced with most features and also it's more reliable unlike Redhat Linux, Sun solaris, HP-UX and also we will have well support from the vendor if we run into any issues. IBM AIX is more user-friendly when compared to linux and easy to use so i would prefer the customers to have their operating system as IBM AIX for companies who has more customers.
macOS is very easily deployed with central MDM/DDM management systems. There are several of these available to select, depending on the amount and type of deployment needed. We use Jamf Pro to support a "zero touch" deployment model, which makes it almost as easy to deploy 100 endpoints as 10 (other than delivery and unboxing).
