My experience with Red Hat Enterprise Linux
We use Red Hat Enterprise Linux (RHEL) for our entire SAP environment as well as every other Linux based system that is of any importance running production workloads. Support is the biggest business problem that using RHEL addresses. Me being an IT Engineer / Linux Admin means I'm one of the few responsible for managing our RHEL systems.
- It's stable
- Has a support system
- Feels trustworthy
- More up to date kernel for hardware compatibility by default
- Better visibility for which desktop environment is default and how to get others
- Bring back the post RHEL source

Enterprise Linux
So we use Red Hat Enterprise Linux (RHEL) on our virtualized virtual machines. We install the OS. And on top of the OS we have applications like Middleware, component, JBoss, IBM, Webware, or other components which our internal application team needs to use it. We are part of a hosting hosting platform, so all the applications. That's it on enterprise Linux.
- Virtualization, like the operating system level task. I see this product is very good and it blends very well with the middleware components like all the JBoss and other things. And other than that, either you install it or a virtual machine or physical servers, it works seamlessly anywhere. And if you want to go further, like Red Hat OpenShift or those things also work very nice with it.
- I would say for me ease of use is very good. We don't find any much more challenges with the LINUX part. Only thing maybe when we go for appliances or network devices, right? Instead of using Enterprise Linux, we use CentOS or some other product. Probably if they can customize for network devices and all, maybe it's more they use other softwares. So that's the only thing I overall I don't have any specific feedback for Linux. Yeah, it's good. Nice.

Red Hat Enterprise Linux (RHEL) is solid!
We currently use Red Hat Enterprise Linux (RHEL) as a lightweight OS for multiple applications including webpages and developers to develop in. The flexibility and support make it one of the best options for a business in my opinion. The documentation as well is very helpful as well as the community efforts behind Linux to lead to better understanding and use cases.
- Lots of flexibility with what you want or dont want installed using it.
- Support is very excellent with someone willing to chat or email you answers if you have questions
- ability to adapt to different use cases and Red Hat Enterprise Linux (RHEL) adding particular functionality that may be useful down the line to the OS.
- More up front way of providing details on support for particular version of OS. If one has 2 years of support but a minor release has 6 years of support. let us know to upgrade if we want better support. or provide a way of showing when support ends on the server itself
- Easier rollback methods when and update doesnt work properly
- More support for legacy stuff like python 2 (backwards compatibility).

RedHat Review
So business problems that we address is really, it's the underlying platform by which we stand up our server technology that we have to support. So we use it as pretty much high available secure operating system for the different services that we have running on them.
- I'd say as far as security, having security built in and baked in from the start, I think Red Hat Enterprise Linux (RHEL) does really well. I think the packaging, the updating as well as just the Ansible integration in it all, just being able to leverage Ansible in a lot of ways with Red Hat Enterprise Linux (RHEL) has been huge. The imaging process is fairly easy, so I just like it overall as far as it comes ready to be implemented, secured, and deployed to production in a lot of ways. As far as the built-in tools make it easier, and it's something I've been familiar with for a long time and something they've improved upon specifically has been Damon's system. CTL has been a huge help.
- I'd say the more advanced security tooling features, but maybe that's because I don't leverage any of the GUI complimentary software suites. But really just being able to leverage FA policy aid A ID and SE Linux in a more intuitive way. Maybe that's just training. I think training is another thing that could be helpful. Just having the training subscriptions accessible for my team can be super helpful. Really the biggest gap we have, it's just making sure that people are trained on the technology we're leveraging.

Long Time Linux user
We use Red Hat Enterprise Linux (RHEL) on our edge devices, web server and scp server.
Internally we use Red Hat Enterprise Linux (RHEL) derivitives such as Rocky or Alma Linux. We’ve seen a few issues with cyphers not being compatible across major releases. Which slows down access for my users who need to access data on various NFS shares.
My users are scientists conducting oceanography research and model development.

RHEL powerful stability.
We have RHEL installed on all of our servers, which allows us to run Open Stack and/or Open Shift. We also use RHEL to help us with our virtualization platform, which allows us to provide our tenants with virtual machines or Kubernetes pods.
- Stable Upgrades.
- Customer support.
- RCA
- Faster root cause analysis.
- Assist with esoteric hardware option.
We use RHEL primarily for Production-level workloads. We also use RHEL on physical and virtual workstations so developers can utilize and maintain their apps with a GUI. Our business problems include an environment heavily reliant on Linux, but end-users often do not have previous Linux experience. RHEL and the GNOME Desktop make it easy for the end-users to have a familiar-feeling environment.
- Outstanding stability. Some air-gapped systems have been online for several months without any intervention.
- Timely updates. Red Hat owns and supports RHEL, so package updates, including applicable errata, are released very quickly.
- Amazing Package Manager. The DNF/yum package manager, along with the Red Hat AppStream and BaseOS repositories, features many up-to-date package versions and a wide variety of packages.
- Other Software Integration & Compatibility with FIPS.

RHEL OS experience
Meteorcomm uses RHEL as the operating system for our Interoperable Train Control Messaging (ITCM) product. RHEL provides a well-supported operating system which provides stability, performance, and high availability, all features which our messaging system requires. ITCM is also built on top of key Red Hat technologies, in particular Messaging Realtime Grid (MRG), allowing us to leverage a well-documented and supported set of features.
- Performance
- Stability
- High availability
- Core messaging functionality
- Support for 32-bit systems (hundreds of thousands of devices in the field running on 32-bit hardware can no longer be updated)
- Ease of use for clustering technology (stonith and fencing documentation could be made more straightforward)
- Support for lightweight containerization which can be orchestrated on single board computers

Linux admin, performing patching and deploying of servers and applications
- Support
- Global affiliations
- Large userbase
- software compatibility
- additional GUIs to choose from
- something like uptrack for kernal patching

I'm happy using RHEL!
System administration and dev/ops.
- System resource management. Software doesn't over use hardware resources and bad behaved software generally doesn't crash other software.
- Software development. Easy to install many languages and write and compile code in those languages.
- Device communication. Its easy to get and use drivers that communicate with serial, or networked, etc. devices.
- It could be easier to determine dependencies of some packages and find the dependent packages.
- It could be easier to configure some of the packages that are configured in the GUI, from the command line, like nmcli.
I use Red Hat Enterprise Linux for Cloud-based Virtual Machines and to deploy large OLTP solutions in highly performant, highly reliable configurations. Red Hat Enterprise Linux supports workloads for SAP, Oracle and other large scale databases for customers and application providers.
- Red Hat Enterprise Linux for SAP/HANA and SAP Applications
- Red Hat Enterprise Linux with High Availability for NFS file system workloads
- Red Hat Enterprise Linux with Enterprise MSSQL with Regional Failover
- Security update process for packages including in core
- Support for non-standard integrations where there is significant market opportunity
- Support for BTRFS

my review.
Admin for USE Linux servers. Running various applications on-prem and in the cloud. Currently working toward SAP deployment. Approx 400 servers across all platforms. Dell Boomi, JMS, Satellite, and Ansible, are some of the apps that come to mind. Can't think of any problems at the moment. We automate builds and get them to app owners to do their thing.
- security
- reliability
- compatibility
- Command changes.
- More and more tools make things more complex, even though they are meant to ease things.

RED HAT
Close to 5000+ servers running on Red Hat Linux and planing to move to Containersation platform to reduce the hardware scalability
- Scalability
- Compliance and Patch management
- Cost reduction
- Automated way of patching and compliance, we know its already available with Ansible but thinking lot of space to add additional features
- Migration to newer version from old EOL systems makes easier adoption of Red Hat Linux
- Expecting more of contianersation and scalable env for new technolgy business applications

Experience with Red Hat Enterprise Linux
The operating system is used in the company. The system is really stable and scalable. It's supported by a robust company that creates the upgrades and vulnerability patches for the releases and applications and this helps to narrow the bridge between the new software compared with other operating systems. RHEL has also many applications on top of the operating system which easy the configuration as a platform integrated with different packages and software that help to ease, manage and scale the configurations of the System. RHEL also is increasing the portfolio of the RHEL with applications such as containers, Ansible, JBoss, and others to have a robust product that can be configured in a single system. The levels of support and the cost of subscription are also competitive for the use of the technology and the IT costs of today.
- Excellent delivery of patches, upgrades, and solutions for vulnerabilities.
- Excellent support
- Competitive prices for today's IT
- It doesn't have another boot environment, like Solaris (BE) or AIX. This will help upgrade O.S. in physical hardware.
- Training courses, documentation and certification is expensive
- Personalized solutions are lacking and high cost which is joined to expensive training makes some products and configurations less attractive than for example AWS.
Red Hat Enterprise Linux is used across the whole organization for our servers, mainly for the mission-critical environments running Oracle DB. It provides an efficient, secure and stable platform we are happy with.
- Quick turnaround time on security releases.
- Reliable OS providing a strong environnement.
- Excellent support through the RHEL site.
- Complex upgrade policies between major versions.
- Hardware compatibility.
- Cost.

RHEL is worth using
It's been used by my organization and we support the product which is robust and secure. It's easy to understand and helpful in troubleshooting issues with different trees assigned for each function.
- It is very secure where root access is the only option to make any major changes, and profiles and roles have been defined to assign user-level access to different directories.
- During troubleshooting it's easy to fix one since each feature has its own directory to look for and it's easy to point to the issue.
- Vulnerabilities are fixed with easy patch creation which fixed the issue quickly and without affecting the other working features.
- Graphical representation has to be more user-friendly.
- Layman should be able to understand the directory and work on the feature enablement and disablement in Linux.
Currently, RHEL is deployed on a legacy blade server (Dell Poweredge 1950) for testing Redmine project management system to track research projects, as well as to test the defectiveness of Redmine in replacing our current production ticketing system.
In Addition to Redmine, we also use Cockpit on RHEL (in our test/development), which functions as a makeshift NOC

- Stability
- Admin workflows
- Will boot on hardware that other systems may not boot on (especially on legacy systems)
- Upgrading
- RPM is getting old
- I'd like to see RHEL move away from rpms, and use a faster system such as apt

RHEL - still one of the best!!
RHEL provides the flexibility and stability required for the implementation of a company-wide application used in the processing of data retrieved from several databases hosted in Oracle. By using RHEL we were able to implement a custom solution, built upon PostgreSQL and RedHat's Jboss, which allowed the automated conversion of the Oracle data into one usable by other applications. RHEL allowed us to implement:
1. An extremely stable system which can best be described as "power on and leave alone"
2. Custom scripts for monitoring both the OS and application
1. An extremely stable system which can best be described as "power on and leave alone"
2. Custom scripts for monitoring both the OS and application
- Very well thought out package manager, that not only installs the software you want but also the prerequisites when necessary.
- Excellent support through the RHEL site and the overall community
- Straightforward installation with easy to follow menus and guides
- Licensing is thoroughly explained and with full instructions on how to apply for new and renewed licenses
- While the command line installation runs well, the desktop GUI tends to be resource intensive at times
- The GUI based install menu does not scale well at times resulting in some menu options spilling offscreen
- By default a menu based network manager should be included, from my experience particularly with the minimal install, this was not the case resulting in me editing the configuration file directly. Additionally, network tools should also be installed by default.
