We performed a comparison between Flatcar Container Linux and Red Hat Enterprise Linux (RHEL) based on real PeerSpot user reviews.
Find out what your peers are saying about Red Hat, Canonical, Oracle and others in Operating Systems (OS) for Business."Flatcar's support is good. The version I am using is stable and allows us to make needed changes."
"RHEL's effect on our organization's management and efficiency is noticeable because we check all the compliance boxes when we run STIG machines."
"The integration with Oracle is the most valuable feature."
"The security it provides is one of the most important features, as are the support and the documentation. The latter helps me to do everything."
"This is a very robust product that doesn't require a lot of handling. It just works."
"The most valuable feature is its security. In Windows, there are risks of attacks or of data leaks because it is using .exe files, but in Red Hat's Linux-based operating system, the data is more secure."
"We find the Red Hat Satellite deployments very useful. It integrates well with other solutions."
"We're very happy with the amount of security customization we've been able to do with RHEL. The fact that Red Hat is really on top of security issues is also valuable. We get daily emails from Red Hat letting us know of possible issues and fixes, which is incredibly helpful for us."
"Until now, RHEL has been the most stable OS I have ever seen. Nothing seems to break, with frequent updates. I have been running it 24/7 for the past 18 months and it runs flawlessly."
"The development teams could sharpen their skills. They should offer applications on the net."
"Sometimes the solution deletes our archives or other features that were useful to us."
"Red Hat can be tricky at times, but all operating systems are. The moves to systemd and NetworkManager haven't made the product more user-friendly. Let's put it that way. The network management they had before was easier and somewhat more reliable than NetworkManager, which Red Hat forces us to use now."
"It could be simplified. I'd like to see them introduce PDFs or documents to better explain technicalities to new users."
"The Authselect tool needs improvement. This tool is used to connect your system to an identity provider or directory service, e.g., openLDAP. There is documentation and descriptions. While there are a few use cases and examples described, it is sometimes hard to use these tools to set up the configuration that we need for our specific environment. I would like it if there was more general information about the tool, not just describing a use case. For example, here is how to do it and how to connect to some kind of openLDAP service as well as more information about when you need to configure certificate services and mutual authentication."
"The biggest thing that is crushing RHEL is documentation. Their documentation is haphazard at best. The man pages that you can use locally are pretty good, they've been fleshed out pretty well, but the documentation from Red Hat itself really needs somebody to go through it and review it."
"Scaling can be complicated and has room for improvement."
"Red Hat Enterprise Linux could do better in live patching. In this day and age, vulnerabilities are constantly emerging, I feel that Red Hat Enterprise Linux has fallen backward in terms of live patching, particularly live kernel patching."
"A completely new setup should not be required when upgrading to a new version."
