We are using Red Hat Enterprise Linux (RHEL) primarily in the health care industry for AI modeling and edge computing. One use case involves specific monitoring in a room with equipment and hardware.

I'm keen on this product because everything works as expected. It has embedded compliance features. We expect more in version 10. The keynote mentioned embedded OpenSCAP reporting, which is something everyone wants.

Red Hat Enterprise Linux has a lot of specialized documentation. Typically, people search on the Internet and find solutions by trial and error. However, everything about Red Hat Enterprise Linux is there in the documentation. You only need to follow it correctly. 

The security features have room for improvement, especially for highly regulated industries like health care. That's why it isn't the primary OS in health care. It would be great if they added some features to address the specific challenges health care providers face. 

It isn't hard to patch, but migrating between versions is difficult. We have the the latest version, but the previous version is still working very well. It's hard to leave a working version to upgrade. I would like more AI features, but those will be added to the next version. We are in an AI age, and it's an area where we need to keep pace. 

I have been using Red Hat Enterprise Linux since version 3, starting around 2000. Currently, we use version 9.4.

The stability of Red Hat Enterprise Linux is excellent. I have nothing negative to report in this area.

Scaling Red Hat Enterprise Linux as our needs change has been good. The older versions continue to work well even as we introduce newer solutions.

I rate Red Hat support nine out of 10. They provide competent support and help resolve issues quickly. You don't need to spend a long time searching for a solution. I don't rely on them much, but it has been a big help for my colleagues.

Positive

I have been using Red Hat Enterprise Linux for many years, so it is my default choice when selecting an operating system.

I'm a technical guy, so I'm not dealing with the money side of things, but we've seen a return on investment in terms of time saved due to the good documentation and support. 

Red Hat Enterprise Linux is expensive, but I'm not paying anything because it's the company's money. However, it's priced comparably to other enterprise Linux solutions. It costs a lot because you have a large staff working on the concept and improving everything. There is an open-source developer part that is free, so you can test everything before buying it. 

I rate Red Hat Enterprise Linux eight out of 10.  I know this is a good product because I've used it for many years, and it continues to improve. The OS is great, so I continue to use it. If I'm working on a new project and given a choice between another solution and Red Hat Enterprise Linux, I would always choose Red Hat for the community, support, and documentation. 

There's a free developer version. If you are thinking about purchasing Red Hat Enterprise Linux, you can try the developer version for free. Practice using Red Hat Enterprise Linux, and you will see the difference between the other distributions and Linux. If you want the product to perform at an enterprise level, you need to learn the product. There a plenty of tools and also the Red Hat Academy.

I use Red Hat Enterprise Linux (RHEL) for its specific security features.

Red Hat Enterprise Linux has specific security checks that are beneficial. We follow its support and it helps with security verification.

The security features are the most valuable. The long-term support for weekends is also beneficial.

Risks, for example, specific to Linux, need improvements.

I would rate Red Hat Enterprise Linux a nine out of ten.

I am a database administrator, and we mostly use Red Hat Enterprise Linux to manage databases. Primarily, we use it for Postgres, as it works best on Red Hat Enterprise Linux (RHEL). It's easiest to set up and has the best documentation.

I'm aware of one customer that is thinking about it. But I'm not sure what specific projects they want to use it for. I think there's one customer who is interested in it and is trying to find a solution that might benefit from it. 

Red Hat Enterprise Linux (RHEL) contributes significantly to our business continuity and compliance efforts. The best example is uptime. Many critical businesses need to be operational twenty-four hours a day. If a database goes down for some reason, it is seldom Red Hat Enterprise Linux that is the issue. This provides peace of mind.

It has helped us centralize development because Red Hat Enterprise Linux has many tools that aren't accessible to our Windows customers. 

Red Hat Enterprise Linux's most valuable feature is its reliability. I don't have to worry about the operating system. It's one of the easiest operating systems for databases, and the integration is excellent. It gives me peace of mind because I can focus on my database work without worrying about my OS. I want to ensure I have applications that run on the OS without searching for temporary fixes or workarounds. 

It has some of the best out-of-the-box security features of any Linux distributor. Red Hat Enterprise Linux has more built-in security features than most standard flavors, or it has implemented them better. 

I haven't identified anything that needs to be proved, but I hope Red Hat Enterprise Linux maintains its reliability.

I have used Red Hat Enterprise Linux for the past five years.

Red Hat Enterprise Linux has been perfect. My Windows customers experience a lot more downtime and bugs. Our critical businesses need to be up 24/7. It's rarely its fault if a database goes down. I would estimate that there's about 10 percent less downtime compared to Windows customers. 

I haven't been involved in any real project that necessitates scaling as our needs change.

The support is excellent compared to other solutions like Oracle. They're knowledgeable and easier to work with. We have a nice, transparent working relationship. 

Positive

The biggest ROI is from Red Hat Enterprise Linux's reliability. If I run databases on Windows, I have to find other tools or workarounds. It's a big hassle. Red Hat Enterprise Linux lowers the total cost of ownership for my customers because I bill fewer hours than I would in a Windows environment. Open-source databases run better on Red Hat Enterprise Linux than on Windows. Most things I need are built-in or can be downloaded from the repo. 

Ubuntu is commonly used, and there's a decent amount of documentation for databases, but it can't compare to Red Hat Enterprise Linux. Setting up Postgres or any open-source database on Red Hat Enterprise Linux is way easier. The documentation is more extensive. It's also easier support because many customers have a subscription with Red Hat.

I rate Red Hat Enterprise Linux nine out of 10.

My advice would be to focus on reliability and ease of integration when choosing a Linux OS. 

In our environment, we primarily use Red Hat Enterprise Linux (RHEL) for managing customer environments and our own. The customer environments are mostly Apache web servers. Some customers have databases, like Postgres, running on Red Hat Enterprise Linux. Others run native Docker on it to manage application dependencies. 

We run containerization projects in the OpenShift environment based on Red Hat Enterprise Linux OS because that's more suitable for containerized workloads. You can do some machines on Red Hat Enterprise Linux, but not all of them. Your worker nodes need to be Red Hat CoreOS, but your master nodes can be Red Hat Enterprise Linux.

I was more experienced with other Linux distributions and Docker. It's open source, so you can fetch Docker and run it, but they don't have support if you have questions or if something isn't working as expected. Podman is similar to Docker. I don't primarily use Red Hat Enterprise Linux for containerization, but I set something up in Podman on Red Hat Enterprise Linux. It isn't used that much. Tinkering and development are the main reasons you would use Podman on a single centralized Red Hat Enterprise Linux machine. If you want to orchestrate on a larger scale, you use OpenShift.

Red Hat Enterprise Linux has made significant contributions to our business continuity and compliance efforts. If a critical vulnerability is spotted in the wild, Red Hat fixes it most of the time. It's usually within a day if it's a zero-day vulnerability. Log4J was a bit more difficult because it was not a single package, but it was mostly shipped with other products. It's hard to analyze which application is vulnerable and whatnot. The solution lets us centralize development. We use Ansible to orchestrate the tooling deployment or to fetch a lot of information. 

Red Hat always clearly describes the vulnerability on its security pages as a CVE score. You can fix errors by patching or mitigating them. If the patch hasn't been released, you can mitigate it to prevent the vulnerability from being exploited. Red Hat Enterprise Linux helps us guide the data and ensure it is correctly placed. I was monitoring it daily, but it was a bit too frequently. Now, we get vulnerability notifications weekly or monthly about a vulnerability or exploit that's been discovered. I also look on Reddit directly to see if there's a fix or a mitigation we can implement.

Sometimes, when upgrading or migrating systems, there are differences in the repositories of the versions that aren't one-to-one replaceable. For example, there are significant differences in the repositories from version 7 to 8. We needed to upgrade Red Hat Enterprise Linux from version 7 to 8 because it had reached the end of its life. A Postgres database was running on it that used a Red Hat Enterprise Linux 7 package, allowing some database or reporting features. When I upgraded to Red Hat Enterprise Linux 8, it was not in the repository. I needed to install it with some workaround. Of course, it was installed with some minor incompatible dependencies. 

I have mixed feelings about the built-in security features. SELinux must be configured correctly for the port and directory, or applications won't run, so we primarily disable it. Sometimes, we enable it and tinker with legacy systems deployed long before I joined the company. However, chances are it will break something if you enable it. 

We have been using RHEL for three years.

Red Hat Enterprise Linux has performed very well for our business-critical applications, with minimal downtime.

We don't need to dynamically scale our application because of our workloads, as we mostly use Red Hat Enterprise Linux for our internal tools. We don't have much demand to scale out.  Containerization lets you quickly scale out your application with some bots if your hardware supports it, and you have enough resources. 

In VMs, we didn't need to dynamically hot plug some service to compensate for the load. It would be vertical scaling by adding more resources. Sometimes, we need to do that for databases that consume a lot of memory, CPU, power, etc.

I rate Red Hat support eight out of 10. It depends on the priority of the requests. We had to launch several P1 requests because something wasn't working in our OpenShift environment, and we were stuck. The support response was quick.

However, we were annoyed that most of the support was based in India. Sometimes, they don't know what the problem is and need to escalate it to an expert in the US or or Germany. It prolongs the ticket resolution, but once it gets to the expert, they fix the problem instantly because they know more. 

Positive

We previously used other Linux distributions with Docker. We prefer Red Hat Enterprise Linux because of its enterprise support capabilities, which open-source distributions like Debian or Ubuntu lack.

I'm unsure what the standard Red Hat Enterprise Linux license costs for one machine. We pay for premium support that guarantees a response in two hours. 

I rate Red Hat Enterprise Linux eight out of 10. If applications and package installations work correctly, I would give it an 8.5. It's a pleasing OS to work with, especially Red Hat Enterprise Linux 8 and 9, which are more polished than Red Hat Enterprise Linux 7. I briefly interacted with Red Hat Enterprise Linux 6, I'm 27, so I know I'm very young, but I know colleagues who worked with Red Hat Enterprise Linux 4, 5, and 3. 

Other open-source Linux distributions might work if they have high levels of community involvement so the community can identify and fix vulnerabilities quickly. Alma and Rocky Linux are all upstream from Red Hat Enterprise Linux. If you want to go with an open-source distribution, I will point you to Alma and Rocky because they are the one-to-one replacements from CentOS. You don't need a subscription. 

We are a big company with many customers, so we prefer a stable platform with support. You can't open a ticket for open-source distributions like Debian or Ubuntu if you have a problem, ticket. With Red Hat, you can open a ticket if you discover a bug. That's included in your support subscription. You also get regular patches, so we can show our customers we are compliant, etcetera. It's a no-brainer to use an enterprise distribution with support instead of something open source where you don't have a support subscription.

Our core business is delivering IT services to public companies, and most of the applications run on Red Hat Enterprise Linux.  We use Red Hat Enterprise Linux to host machines that various teams of developers use. Most of the time, we use Red Hat Enterprise Linux to run websites and various software applications, including CMS tools like Drupal, SIP, and Azure CMS. We also run business-critical applications on Red Hat Enterprise Linux. We're still looking to migrate everything on the mainframe to Red Hat Enterprise Linux, and our middleware databases run on it.

While we don't have any containerization projects yet, we have a few in the pipeline. We plan to add some new Docker clusters and Kubernetes clusters with OpenShift. The presentation on AI workloads looked interesting, but we must implement OpenShift containers first and enable AI tools. 

Red Hat Enterprise Linux is quite good for business continuity. The system has supported some applications and businesses fine for years without any patches. It's highly robust, which is one of the main reasons we continue to use Red Hat Enterprise Linux. 

Red Hat is based on Linux, so the security is more stable than in other systems. For instance, we cannot reuse machine credentials. We use key certificates to connect to the machine. It's not like a user password. Without a key to access the machine, you cannot do anything. There are specific controls on user access, and you can limit the privileges.  

Using Red Hat Insights with a Rapid7 tool, we've avoided breaches by detecting and patching vulnerabilities early. Now, we're using the Ansible Automation platform to manage the system better and provision new VMs more efficiently. 

We've built scripts that have not performed well internally. They can cause problems, but we're using the Ansible Automation Platform to avoid such problems. For instance, a script for creating VMs on VMware and deleted some. That has no longer happened since we implemented Ansible.

Although we are happy with the current capabilities, we would welcome new features, particularly in the AI domain.

I have used Red Hat Enterprise Linux for about five years, but my company has used it for around 10 years.

Red Hat Enterprise Linux is very robust and stable.

Red Hat Enterprise Linux is scalable, and provisioning new setups is more efficient with the Ansible Automation Platform. 

I rate Red Hat support eight out of 10. 

Positive

We joined the company when Red Hat Enterprise Linux was already selected, mainly because of its support and security aspects.

The robustness and support provide the biggest return on investment. It ensures stability and security for critical applications and helps deliver IT services effectively. The support behind it is excellent.

Red Hat Enterprise Linux lowers the total cost of ownership. We have 65 percent of our VMs running on Red Hat Enterprise Linux and 65 percent of the business we provide to our customers is based on the platform. 

The pricing and licensing, especially for options like the Red Hat Enterprise Linux Ansible Automation Platform, are quite expensive.

I rate Red Hat Enterprise Linux nine out of 10. I recommend going with Red Hat Enterprise Linux because it's excellent. I asked a security team colleague why they don't use Red Hat Enterprise Linux, and he couldn't say why. It's one of the best from our perspective, and the support behind it is superb.
