We performed a comparison between Flatcar Container Linux and Ubuntu Linux based on real PeerSpot user reviews.
Find out in this report how the two Operating Systems (OS) for Business solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI.
"The integrated solution approach reduces our TCO tremendously because we are able to focus on innovation instead of operations."
"The most valuable features are the specification and technical guides, they are most important the security."
"The most valuable thing about Red Hat is its stability, uptime, and support for various hardware vendors. Linux servers, in general, are relatively secure and they are more secure than Windows and other products."
"I like the fact that most of the system configuration is Namespace so it's easy to get to and easy to configure, and most of it still uses text documents. Not all of it's a menu-driven-type entry. I also like the fact that it's a very standard file system layout so it's easy to navigate."
"The feature that I like the most is that we can integrate it easily with our existing infrastructure. We found that it is much easier to deploy RHEL in our environment compared to a competing distribution like Ubuntu."
"RHEL is stable, mature, and relatively easy to handle. I'm pretty confident in it. We haven't had to raise a serious support ticket for any server in I don't know how many years."
"The security features are better than many other solutions offer."
"It is a well-established operating system. We have tried to implement almost every feature of a version in our environment, and it has been very reliable. We are not facing many production issues on a day-to-day basis. They have well-documented articles on their documentation site and a knowledge base on their website. When we need to implement anything, we are able to find information about the best practices and the solution."
"Flatcar's support is good. The version I am using is stable and allows us to make needed changes."
"There are several manuals online that are free and available to help you."
"It is stable and modern."
"The auto upgrade operating system feature."
"Ubuntu is free and stable."
"Ubuntu Linux is very easy to learn, manage, and keep updated."
"Ubuntu is great because you get most of the packages or software you need. You get the latest updates and stuff fairly fast."
"What makes Ubuntu easy to use is the large set of applications and the interface. The graphical interface is user friendly."
"This open source operating system promotes very secure environments with less possibility of being attacked. Support for this system is great because of its quick SLA."
"It is a bit on the pricier side. However, due to the stability and support that they provide to my management and me, we really don't see a reason to choose another way to go. It is hard to get good support."
"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."
"Security could be increased."
"I would like to see improvements made to the subscriptions and management of them."
"Large application vendors may not have certified RHEL, or they have certified an older version. Most of the large application vendors are unfamiliar with the versioning that RHEL introduced, which I strongly support. They will support a given sub-version up to a point, not realizing that the sub-versions are essentially additive."
"Their pricing and documentation can be improved."
"An area for improvement in RHEL has to do with security policies. I know they are doing something about this in RHEL 9, but I haven't worked with that version yet. When it comes to security policies in RHEL 8, it is a bit behind. It would be better if we could just enforce a certain security policy such as CIS Level 1. That was not available, out-of-the-box, in RHEL 8."
"It is mostly better than other solutions. However, it is sometimes difficult for disaster recovery, so we have to plan accordingly."
"The development teams could sharpen their skills. They should offer applications on the net."
"It would be nice to see more compatibility with certain Microsoft solutions, such as OneDrive."
"The solution could improve by being more user-friendly."
"More security features are needed to protect the current file system to prevent attacks."
"In general, Windows is easier to use and friendlier to deal with than Ubuntu."
"It could be better for working with software at a high resolution."
"The solution could improve by having better integration."
"When installing software, an online interface has to be used and commands written to run the installation. The solution could be improved if it was possible to click twice in an icon for the installation process to begin."
"I think Ubuntu's performance is fine and so is its user interface. However, the latter is not as fancy as Microsoft Windows. It could be a bit fancier and easier to use."
