Systems remain reliable and secure with prompt updates and reduced downtime
What is our primary use case?
How has it helped my organization?
My company benefits from these features as our systems must remain operational. When systems go down, it results in significant monetary losses per hour, so having RHEL running and security patches available quicker than other distributions is crucial for maintaining satisfaction.
What is most valuable?
Red Hat Enterprise Linux (RHEL) helps me solve pain points. It's a good server operating system, better than all the alternatives, with full support and stability whereas many other Linux distros may be more flighty and not as stable.
It's more reliable, more stable, and doesn't break down. Stability is the feature of RHEL that I appreciate the most since systems remain operational without rebuilds. Security and stability are definitely important aspects.
We manage our Red Hat Enterprise Linux (RHEL) systems for provisioning and patching using Red Hat Satellite for patch management, which is acceptable but could use some modernization, and we also use Ansible for configuration management. I'd prefer to see those two tools work better together, and if we could use configuration as code for Red Hat Satellite, it would make it even better.
I have been involved in RHEL upgrades and migrations in general. The process typically involves rebuilding and migrating; we rebuild the OS and migrate. We have tried the upgrade-in-place method, but it can be very lengthy and has more room for errors. Generally, we build new and migrate over first, and if we can't do that, we'll do the upgrade-in-place for applications that people understand, really just needing the same setup as before.
What needs improvement?
I would suggest to RHEL to maintain vigilance on vulnerabilities and resolve them more quickly. People compare other operating systems based on vulnerabilities. I know that RHEL is stable, but other teams might look at the overall vulnerability counts. Maintaining performance is also important; RHEL has very good performance, so maintaining those fundamentals is crucial as that's what people sometimes seek.
To make it a perfect ten, I would suggest there is always room for improvement; reducing the frequency of changes would help. There are always significant changes, such as with SystemD, and I understand that's more of the community driving much of this change. Other changes are coming through, such as changing command names. Maintaining backwards compatibility would help turn a nine, which is already very good, into a ten.
For how long have I used the solution?
I have been using Red Hat Enterprise Linux (RHEL) for approximately 12 years.
What do I think about the stability of the solution?
Red Hat Enterprise Linux (RHEL) is stable and secure; these are the two biggest factors that drive our usage.
What do I think about the scalability of the solution?
Red Hat Enterprise Linux (RHEL) scales very with the growing needs of my company. It can natively handle however many servers we need to deploy.
We can manage anything we need to do, and now that we can do it all as code, that enables scaling. RHEL natively works very with code, and everyone that manages Linux in our company does it either through command line or code, which differs from the Windows experience and helps us scale.
How are customer service and support?
The customer service and technical support of Red Hat Enterprise Linux (RHEL) is good. That said, it depends on who you get and how they understand our problems. Sometimes our problems are simple and sometimes very complex. Generally, we're able to get our issues resolved with minimal intervention or administrative burden.
Which solution did I use previously and why did I switch?
We consider other solutions while using Red Hat Enterprise Linux (RHEL), and we're constantly looking at other vendors. Their products aren't as good; they might be less expensive, however, they aren't as fully developed.
How was the initial setup?
Cloud licensing is confusing. We have subscriptions available to us, which is why we opted for bring-your-own-subscription. However, even then, the options make deployment difficult since we need to ensure the OS is registered to our satellite system for subscription management, not through the cloud services.
What about the implementation team?
We decided to bring our subscription instead of purchasing Red Hat Enterprise Linux (RHEL) on AWS Marketplace.
What was our ROI?
From my perspective, the biggest return on investment when using Red Hat Enterprise Linux (RHEL) is its stability and support, with stability being a core fundamental.
What's my experience with pricing, setup cost, and licensing?
My experience with pricing and setup costs indicates that licensing is confusing in the cloud. We have subscriptions available to us, which is why we opted for bring-your-own-subscription.
Which other solutions did I evaluate?
Some other solutions we consider include Canonical and Ubuntu, which sometimes perform better in the desktop world since they have support for desktop distributions. SUSE is another option we consider; those are the big three, and we wouldn't consider anything outside of that group extensively.
What other advice do I have?
On a scale of one to ten, I rate Red Hat Enterprise Linux (RHEL) a nine out of ten.
Which deployment model are you using for this solution?
Hybrid Cloud
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?
Amazon Web Services (AWS)

What problems is the product solving and how is that benefiting you?
High end computing in a secure manor
Easy to use, and very stable with satellite
What do you like best about the product?
Versatile and stable. Like how easy it is to manage 400+ linux vm servers.
What do you dislike about the product?
A bit locked in with tools like libreswan and strongswan no being compiled with options for msChap for example.
What problems is the product solving and how is that benefiting you?
We have many third party tools running on Linux. Also hosting many Oracle Database instances on premissis
product evaluation
What do you like best about the product?
product updates are easy to deploy and the product is stable
What do you dislike about the product?
Enterprise Linux is sometimes too far behind latest software releases.
What problems is the product solving and how is that benefiting you?
easy to deploy applications
Strong security features and reliable performance increase deployment confidence
What is our primary use case?
My main use cases for Red Hat Enterprise Linux (RHEL) are mostly development at first, and then after that, it's actually running full production loads on it.
What is most valuable?
One of the nice pain points that Red Hat Enterprise Linux (RHEL) addresses compared to other distributions is the polished applications within it.
Their repository tends to be more foolproof. The SELinux feature in RHEL is pretty strong.
SELinux is not something that I was ever using before in the open source community, and it was very confusing at first; however, after a while, it made sense why that layer exists. The SELinux feature and other features of RHEL benefit my company by allowing us to lock in the server more traditionally than we would be able to with special permissions.
It's about getting very granular versus just putting an umbrella on some things, and security-wise, it's very effective.
The security features of Red Hat Enterprise Linux (RHEL), including SELinux and its features, make it easier to be aware of compromises.
The Insights tool is very good at providing CVEs to alert us about vulnerabilities quickly. I can't quantify the impact in percentage terms since I haven't faced specific situations. However, the outlook compared to other distributions looks good.
What needs improvement?
To improve Red Hat Enterprise Linux (RHEL), it would be helpful to have a step-by-step process to make setup easier. Cockpit needs more features to manage complex tasks such as RAID configurations, as most of that is reserved for the command line.
For how long have I used the solution?
I have been using Red Hat Enterprise Linux (RHEL) for about a year and a half.
What do I think about the stability of the solution?
I find Red Hat Enterprise Linux (RHEL) to be super stable and super reliable.
What do I think about the scalability of the solution?
I have not scaled Red Hat Enterprise Linux (RHEL) outside of using templates and cloning features. I haven't scaled it out with OpenShift yet; it's something I want to explore, as I now understand what tools OpenShift can offer to scale out RHEL machines effectively.
How are customer service and support?
My experience with customer service and technical support for Red Hat Enterprise Linux (RHEL) is mixed. On a professional level, they are very responsive, which is part of the contract, but on a personal level, responses can take forever, and I often get pointed to community posts.
How would you rate customer service and support?
Positive
Which solution did I use previously and why did I switch?
We did not consider any other OS solutions while using Red Hat Enterprise Linux (RHEL), although there have been discussions about using Ubuntu. I don't think it will go that way because we are very satisfied with what RHEL offers overall.
What was our ROI?
The biggest return on investment with Red Hat Enterprise Linux (RHEL) is that every time I put an application or tool in there, it's going to work. I don't have to second-guess it or go back; I know it will be a polished application.
What's my experience with pricing, setup cost, and licensing?
Regarding the experience with pricing, setup costs, and licensing for Red Hat Enterprise Linux (RHEL), I would say it's beyond my pay grade. That said, it's not cheap at all. While it could always be cheaper, they provide substantial value for the money, and they consistently introduce new features that add value.
What other advice do I have?
I would rate Red Hat Enterprise Linux (RHEL) as a ten out of ten overall.
It's a great OS that has grown on me over time, and the more I use it, the more I understand its value and why it costs what it does.
Which deployment model are you using for this solution?
On-premises
RedHat is the industry standard
What do you like best about the product?
RedHat, for the most part, just works. If it needs to run, and it needs to run reliably, it's the only platform in the game, particularly in offline environments. I use it for both my workstations and servers, and it performs as needed in both use cases.
What do you dislike about the product?
Support for disconnected systems could improve. Much of RedHat documentation presumes internet access, and doesn't always have easy-to-find implementations for environments that do not have, and cannot have, internet access.
What problems is the product solving and how is that benefiting you?
RedHat provides a platform that can be reliably secured to DoD standards and, importantly, still work without too much fuss.
Linux over Windows
What do you like best about the product?
The ability to customize my experience in a desktop environment in Paramount in my workflows. Development is my passion and is so much easier than on windows.
What do you dislike about the product?
I don't dislikes RHEL in anyway. I only dislikes the fact that business are scared of migrating from the Windows Desktop environment to Linux.
What problems is the product solving and how is that benefiting you?
Server virtualization
Great to work with sometimes a pain on major upgrades
What do you like best about the product?
Consistency across versions and stability
What do you dislike about the product?
Initial setup with subscription manager can be overwhelming
What problems is the product solving and how is that benefiting you?
It allows me to have consistency across infrastructure
