Linux overall needs improvement. They cannot go much beyond what Linus Torvalds's kernel implementation can do. I come from AIX, and there were very cool things in AIX that I am missing dearly, e.g., being able to support not only adding, but also reducing memory and number of processors. That is not supported on Linux right now, and it is the same for the mainstream file systems supported by Red Hat. There is no way of reducing a file system or logical volume. Whereas, in AIX, it was a shoo-in. These are the little things where we can say, "Ah, we are missing AIX for that." We are not loving our servers anymore. If we need them, we create them. When we don't need them, we delete them. That is what they are. They are just commodities. They are just a transient product.

Their pricing and documentation can be improved. They need to have developer variance that's more developer-friendly and less costly. They have a free developer version, but that's very limited in terms of features from RHEL. They also need to build their own open-source community.

It is mostly better than other solutions. However, it is sometimes difficult for disaster recovery, so we have to plan accordingly.

Sometimes they don't have new versions for applications like Apache or PHP. I understand it's because they have to have support for them, so they can't have the latest version all the time, but that's the main thing I see that could be improved. So when you use RHEL and you want to install, let's say, Apache or PHP, you do a "dnf install php" and you get a specific version that Red Hat releases. But that isn't the latest version that PHP has released, because Red Hat has to make sure that they can support it. The compatibility with the latest version of Apache or PHP lags because RHEL does not release updates of the latest versions. It's the same with the kernel. Sometimes they are a bit behind in the kernel version. That's the same issue. They have to test it and support it for so many years so that's why they are a bit behind on the kernel as well.

"Benchmarks" is an ambiguous term. Are you referring to security benchmarks or performance benchmarks? In either case, which specify type of benchmark are you looking for?

Doing any kind of benchmark between an OS developed exclusively for workstation (Windows10) and an OS developed mostly for Servers doesn’t make any sense.

Red Hat Enterprise Linux is fantastic. It is an inexpensive solution that has excellent security, performance, and stability, and also lots of features. I specifically like that the solution has features that simplify adoption for non-Linux users, which makes it easier for administrators too. RHEL also has good customer support. In addition, RHEL enables me to deploy current applications as well as emerging workloads across all virtualized hybrid cloud and multi-cloud environments, which I find to be very helpful. Besides the stability and reliability of the OS, it provides a great user experience. Moreso, the fact that it is open-source and leading the open-source market trends and technologies speaks for itself. Although RHEL has a lot to offer, sometimes it can be difficult during disaster recovery. But if you know that ahead of time, you can plan accordingly. And their documentation definitely has room for improvement. In the past I have used Centos. Generally it was good, but the reason why I switched was because it used to be very stable and now it is not. Its operating system used to be great but when the updates came out, something changed. Additionally, if you are new to using Centos, the initial setup is not that straightforward unless you have prior experience with Linux and know your way around. (In which case installation won’t be difficult.) I also found that CentOS didn’t scale as well as I expected it to. For my needs, I was also hoping it would have more options built into the wizard. Conclusion: Although CentOS is a very efficient product and is very powerful with a lot of capabilities, I would still recommend RHEL. On a scale of one to ten, I would rate RHEL an eight. As someone who has used other systems, I can say from experience that Red Hat is one of the best - specifically in terms of its ability and consistency of the operating system.

@Netanya Carmi,This is an insightful article.  But in my opinion, Rocky Linux (as a potential successor) of CentOS, will be the next big thing in the open-source world, as already many solutions are supporting it though only the BETA version for now.  Still, your article is quite a heads up. Thanks!
