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.

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.

We are a telco company hosting internal applications on the OpenShift platform. It's for general IT workloads, such as backend systems for billing. We are also using it for containerization projects.

With an open-source solution, there is no vendor lock-in at the OS layer, so it's more flexible. I am happy with the value Red Hat delivers, so we don't see a reason to change that.

I like open source and prefer it over some closed proprietary software. In my early days, I was involved in the open-source community of the Red Hat Directory Server, communicating with developers to ensure password policies were implemented and asking questions. It showed me the power of open source.

While the built-in security features are excellent, we don't use all of them. It has many available capabilities, but it's not always up to the infrastructure people to decide what to use for security. 

I'm happy with the value Red Hat Enterprise Linux delivers, but there's always room to improve. 

I have been using Red Hat Enterprise Linux for almost twenty years.

I've never heard of any issues with Red Hat Enterprise Linux's performance on business-critical workloads. If there is a problem, it's mostly on the application layer, not the operating system.

Red Hat Enterprise Linux has native containerization, so it can scale. It uses open-source technology and has Kubernetes underneath, which gives you the scaling you need. .

I rate Red Hat support seven out of 10.

Neutral

We have been a Red Hat customer for over a year, and we are happy with the value it delivers.

I don't know the exact pricing. Red Hat's subscription model is cost-effective because you pay as you go, which is better than paying upfront high license costs. 

I rate Red Hat Enterprise Linux eight out of 10. If you plan to implement Red Hat Enterprise Linux, make sure you get a vendor who can deliver and support it correctly. 

We use the solution internally for developing our software, including running databases and banking applications. These are the kinds of services we provide to customers, as well as our own internal software products.

The solution has helped enormously in terms of development and infrastructure. It enables us to centralize development and improve productivity significantly by providing a stable platform with documentation and best practices for deploying robust solutions.

One of the most valuable features is the ease of consumption and the extensive community-driven resources. The documentation is extensive, allowing users to get started without difficulty. 

Additionally, the support and stability provided by Red Hat Enterprise Linux contribute significantly to its value.

The solution requires a lot of prerequisites and understanding of the Red Hat ecosystem before one can get started. This complexity could be improved. 

More comprehensive support for OpenShift integrations and a less customized, Red Hat-specific setup process would be beneficial.

We have been using the solution for more than ten years.

The solution has been stable. We partner closely with Red Hat, and the operating system has been reliable for a long time.

I am not directly involved with scaling aspects, so I can't provide specific insights on this.

We have been very happy with customer service and support. Red Hat offers prompt support with a good turnaround time, effectively addressing any issues.

Positive

The pricing is competitive. It is not cheap. That said, it provides value considering what it offers.

I would suggest that anyone starting to develop should consider starting with a community-based version, however, for production workloads, it is important to have the support model from Red Hat as it provides stability and quick issue resolution.

We use the solution primarily for simulation and CAD solutions. It serves as the main use for our operating systems.

The openness of the operating system makes auditing a lot easier, plus the tools for auditing make that a lot easier to maintain. 

Automation makes compliance a lot easier. 

The knowledge gained from using the system completely makes troubleshooting easier and increases the knowledge pool in the company.

The extendibility of the solution and its openness, along with its integration with all of our other open-source projects, are highly valuable. 

We appreciate that it is one of the few enterprise-enabled Linux operating systems we can use. 

It is very extensible, which aids as our needs change.

We have encountered compatibility issues with certain hypervisors, mainly with Red Hat Enterprise Linux six hosts on the newer versions of FoxMox.

I have been using Red Hat Enterprise Linux for over ten years.

The solution has performed really well for our business-critical applications and is very stable. I have no issues.

The solution is very extensible, adapting perfectly as our needs change.

Customer support is very helpful and insightful. I would rate it very well, approximately an eight on a scale of one to ten.

Positive

The biggest return on investment is the knowledge gained by using the system. The access we have to the operating system increases user involvement and facilitates troubleshooting, thus expanding the company's knowledge pool.

The pricing and licensing are reasonable.

For non-business critical applications, a third-party Linux OS may suffice, however, for something running 24/7, it is advisable to go for stability and enterprise support.

We use Red Hat Enterprise Linux (RHEL) to run applications and databases related to the European Parliament's business. For example, we use SAP for financial operations. It's not my domain, but I know the leadership plans to implement AI workloads. We translate every document into 27 languages manually, but we plan to use AI and machine language translation. 

Using a Red Hat Enterprise Linux Cluster in the SAP environments gives us high availability and disaster recovery, so our data is safe. I think it's a geo-cluster for the whole SAP environment. Whenever something happens, it almost automatically shifts to the other.

The support for OpenShift and CoreOS is valuable, as we frequently use support services and rely heavily on Red Hat support for assistance.

When we started using Red Hat Enterprise Linux, it was a struggle to install CoreOS because we were used to using a Satellite server with Red Hat. The people in charge of setting up OpenShift and installing Red Hat Enterprise Linux on the nodes had a hard time. I don't know why, but I think it was because the OpenShift cluster included VMs and bare metal machines.

I joined the European Parliament in 2012, and we have been using Red Hat Enterprise Linux for 12 years. 

We do not have any issues with its performance. The system functions well.

Scaling the operating system is transparent. We work with VMware, so whenever there is a need for more RAM and memory, the process is seamless to the customer.

I rate Red Hat support eight out of 10. Customer service and support are excellent. Support is available depending on the priority and the support package. I am happy with the service. However, navigating through documentation can be challenging.

Positive

We started with Mini Solaris and gradually migrated to Red Hat Enterprise Linux.

Initially, setting up OpenShift and the installation was somewhat complicated, especially when dealing with bare metal machines.

As a nonprofit business, we do not focus on return on investment in monetary terms. However, a big community makes it easy to gather opinions and help from outside sources, which is a return on investment.

We compared Red Hat Enterprise Linux and SUSE. While SUSE is generally the preferred Linux distro for SAP, we chose Red Hat Enterprise Linux because we had more in-house knowledge of the platform and better support. 

I rate Red Hat Enterprise Linux eight out of 10. I used to be an AIX system admin, and I still prefer that operating system. I would recommend considering Red Hat's benefits, such as support. I used to work in IBM support, and Red Hat has a significant advantage in this realm. Also, many corporations merge firms and combine workforces, and RHEL can adapt to these changes.
