Red Hat Enterprise Linux (RHEL) Reviews

For the past couple of years, our contractor team has been engaged with the Department of Veterans Affairs, focusing on developing and deploying software and containers and we use Red Hat Enterprise Linux for that.

One of the most valuable aspects is the ease of installing packages on the server. When we need to run specific software, adding and installing packages on Red Hat Enterprise Linux is quite straightforward.

When we initially began working with containers, we encountered some challenges with compatibility. Red Hat provided an older and somewhat outdated version of Docker, which made the early stages of our container journey more challenging than I would have preferred.

I have been using Red Hat Enterprise Linux for three years.

The customer support they provide is highly commendable. I would rate it nine out of ten.

Positive

I've mainly used Windows on my computer or laptop. However, it was a different scenario when we were developing in the cloud and were given Red Hat Enterprise Linux servers to work with.

We regularly perform upgrades on our OpenShift clusters, typically on a monthly basis. When it comes to the Red Hat Enterprise Linux servers, we frequently update the images on our virtual machines to ensure that we stay current with the latest versions. We're actively working on implementing automation using Ansible to streamline and facilitate these tasks.

Overall, I would rate it nine out of ten.

We use RHEL for database servers, a few of them run Oracle servers, and we are also using it for some of the network and infrastructure services.

The best operating system I've ever used is Red Hat, in terms of its ability and consistency of the operating system. Other than that, the vast majority of applications that I had, I could deploy those on Red Hat without much effort as it supported a vast majority of applications. I never faced any major issues with the OS, the support is also very good.

The most valuable features are:

• The stability and reliability of the OS itself
• Being open-source and leading the open-source market trends/ technologies
  
• The wide variety of applications we can deploy on Red Hat
• Their support 

I am a big fan of the OS and the user experience. They're very good. The OS is very stable and very good in performance as well.

RHEL enables us to deploy current applications and emerging workloads across all virtualized hybrid cloud and multi-cloud environments. It is one of the most stable OS that are available. 

We use RHEL to run multiple versions of the same applications and databases on a specific operating system. We have several deployments of database and a few of them are running on a bit older versions of Red Hat and some of them are running on newer versions. We are running different versions on different platforms. The management aspect is also very good, especially when we need updates on the different packages from the RH support network, management is easy.

We also use the tracing and monitoring tools to monitor OS as well as applications running on RHEL platform. The OpenShift is also a big plus through which you can manage and deploy enterprise-ready containerized workloads.

Being an advocate of open source technologies I always wished that Red Hat subscription/ support should be offered free of cost. Having said that, I understand the economics involved in running large enterprise like Red Hat; support cost is one area that can be improved. They should offer it at reduced prices.

I have been using RHEL since the start of my technical career, which was around the mid of 2003. So it's been almost 18+ years. I started using RH when it was version 7.

Stability has always been a plus for RHEL. 

Scalability is excellent. With the introduction of hybrid and multi-cloud support, one can scale up as well as scale out his workloads pretty easily. We usually scale up our traditional workloads when we need more resources i.e., during peak seasons. 

Four people in my team are responsible for deployment and support of Linux based workloads. 

We have around 300 virtual machines (VMs) and roughly 20% of them are running on Linux environment.

Whenever I open a case, I believe the support team will be able to solve my problem. They are very good at it. The documentation RHEL provides is also very good. Almost all the time, I get a solution to my problem. :)

We are using other flavors of Linux OSes, that include Oracle Enterprise Linux (OEL) and CentOS, both of which are binary compatible with RHEL. We are also using a couple of other Linux flavors like Ubuntu and OpenSUSE.

RHEL provides features that help speed our deployment. Installing on a physical server takes more time than installing it onto a virtual machine (VM).

Because of absence of local support in our part of the region, we did find some difficulties in the initial deployments with hardware vendors/ partners when we started in 2003. The local partners didn't have much knowledge of Linux environments at that time, and the support for hardware was also a bit tricky. The deployment took a couple of days until we got support from the hardware manufacturer.

Nowadays, it's very good. I managed to get good support from the hardware vendors after that incident.

We have our own deployment plans for the operating systems that include some baseline configurations and security checklists.

We usually deploy in-house as we have a trained team. Occasionally, little help is sought from the vendor teams, some of them have skilled professionals.

RHEL offers an efficient, cost-effective and reliable OS environment for enterprise-level environments. Similarly cost of running operations and the scalability factors make RHEL a good choice for providing a better ROI. The feature set it offers, support for a variety of applications, ease of deployment, and an excellent level of support all result in a good ROI. 

I believe for an enterprise-level operating system and the feature set RHEL offers, it's like any other enterprise platform cost. The introduction of OpenShift is also a big plus in terms of deployment and management of container based workloads. Red Hat as mentioned earlier can improve a bit on support/ subscription costs.

We had been using a couple of Red Hat variants for some scientific experiments that included Scientific Linux CERN (SLC) and Scientific Linux (SL), which were a confidence booster for choosing and deploying RHEL for production workloads.

Since I started with version RH 7, I believe the GUI is quite close to any other GUI operating system. There have always been a variety of tools and features that attract a non-Linux user.  As already mentioned, RHEL has been a pioneer in open-source technologies; it continued to evolve with changing market needs, that has been a big success for them.

I would definitely advise choosing RHEL if you need stability, scalability, and reliability of the OS platform. I would be a big advocate for the use of Red Hat to any new person who wants to deploy his production workloads, on-prem or on cloud on a Linux environment.

I would rate it a nine out of ten. It's near perfect. 

Most of our servers are low latency, and it's easier to have low latency applications run on Linux. Red Hat Enterprise Linux's installation is easy. We don't have to reboot Red Hat Enterprise Linux like Windows, where there are a bunch of system updates that you have to do. Red Hat Enterprise Linux is just easier to manage.

Red Hat Enterprise Linux's most valuable feature is its stability.

We would like to have a better understanding of what to expect when we move to a different version of Red Hat Enterprise Linux.

A latency always gets introduced when we move to newer Red Hat versions. I wish we wouldn't see that as often as we do nowadays. It would be nice to know the changes upfront rather than when we have to open a case, go through a couple of months, and then find a good resolution. We want a better understanding of what we will see when we update the kernel from seven to eight.

I have been using Red Hat Enterprise Linux for 15 years.

Red Hat Enterprise Linux is a pretty stable solution. Its stability is a lot better than most other operating systems.

Red Hat Enterprise Linux's scalability is better than other competitors.

For the most part, Red Hat Enterprise Linux's support has been really good. Most of the time, we've had to escalate it to get a good response.

Neutral

Red Hat Enterprise Linux’s initial setup is pretty straightforward.

Whenever we see a compliance issue and need a patch, it's been relatively easy to get Red Hat Enterprise Linux to update it.

We have a mix of Windows and Linux. Around 80 percent of our systems are Red Hat, but we also have Windows. So it depends on the application.

Most applications are compatible with Red Hat Enterprise Linux. It's easier to tune on a Red Hat system than on another OS. We could pin applications to a core with Red Hat Enterprise Linux. In terms of tuning, Red Hat Enterprise Linux performs better in the long run.

Overall, I rate Red Hat Enterprise Linux an eight out of ten.

One of our use cases is for our in-house applications that the development team builds. We also use it for typical tasks like running Jenkins, GitLab, and other development tools to make them accessible for the developers who write code and do software development.

One of Red Hat Enterprise Linux’s valuable features is its enterprise-level security. We are guaranteed that it's secure, and that's important for us because we need to comply with security regulations. Security always remains a top priority.

We just run Red Hat Enterprise Linux’s built-in security features day in and day out. We know it's secure, and then we just move on to other tasks. It's like a routine where we don't have to think too much because we know it's already integrated into the whole enterprise. It's the next step, and it gives us more time to focus on other tasks.

We are trying to figure out how to enable encryption or just encryption. The last thing we want is to use locks, which are a hassle for encryption. We don't have the personnel to unlock the system every time it gets rebooted. I know there's a way, like on Windows, where they have TPM. I'm not sure how Red Hat Enterprise Linux’s TPM works. That's one of the issues we face—how to utilize TPM effectively.

I think in the future, if the company requires us to encrypt everything, it would be a time-consuming process. I'm not sure how long that would take or if it will happen. I just want to understand how Red Hat Enterprise Linux and TPM work or if there's an existing solution that works similarly where I don't necessarily have to be present every time my system reboots and enter a password. At least for Windows, we know that it works, but I'm not familiar with the equivalent functionality in Red Hat Enterprise Linux.

In future releases, I would prefer a Red Hat Enterprise Linux image that fits on a DVD. The Red Hat Enterprise Linux image keeps getting larger and larger. One of the biggest requirements for my company is that it has to fit on a DVD. Now, with Red Hat Enterprise Linux 9 approaching close to ten gigabytes, it won't fit on a DVD anymore. The last thing we want to resort to is using Blu-ray. I prefer not to use Blu-ray. So we need to keep the image size on a DVD smaller. That's one of the main issues. And we can't use USB sticks either, even though they're a new option. Everything needs to be burned on a DVD. So having a Red Hat Enterprise Linux image that fits on a DVD would be beneficial for any future versions or releases.

I have been using this solution for eight years now. Right now, we're migrating. I'm trying to upgrade from Red Hat Enterprise Linux 6 to Red Hat Enterprise Linux 7. And that process is painstaking. It's taking a lot of time. I know we want to get that done before October because I think that's when the security support for Red Hat Enterprise Linux 6 expires. We need to move everything to Red Hat Enterprise Linux 7.

We have a lot of legacy systems, and it's very time-consuming trying to figure out what will work and which version of Red Hat Enterprise Linux will support all our applications. So it's just a lengthy process to go through.

In terms of stability, there have been some issues, particularly on the workstation side. The workstation tends to freeze up occasionally, requiring a system restart. The server side, on the other hand, works well as intended. Although Red Hat Enterprise Linux is primarily designed for servers, our developers use it as a workstation, and that can sometimes cause issues after a couple of days of continuous use.

They may need to restart their systems when something freezes or stops working. So it's one of those things we encounter.

I don't really use it extensively. I have some knowledge and experience with it, but I don't heavily rely on Red Hat support. Whenever I encounter a problem, I usually turn to Google for solutions.

The knowledge base provided by Red Hat exists, but I find it difficult to navigate. The information seems scattered and hard to find. I tend to prefer searching on Google since I can get immediate answers there compared to the knowledge base, which can be challenging to navigate. It seems like the knowledge base could use some improvement.

One of the main advantages is the level of support. Red Hat Enterprise Linux provides nearly ten years of support, including two years of extended support, whereas other operating systems typically have one or two major versions released within five years. It can be challenging to allocate the budget for frequent updates over such a short period. So I think that's the main appeal of Red Hat Enterprise Linux—its ten-year support with an additional two years.

Since I've been working with Red Hat Enterprise Linux for a long time, it feels easy for me. However, for someone completely new to it, especially coming from a Windows background, it might seem more complicated. But for me, it's second nature and not that difficult. So the initial setup depends on the level of familiarity with the system.

For a brand-new system, it might take around ten minutes.

I have worked with CentOS, Fedora, and Ubuntu. So I have experience with different flavors of Linux, from the Ubuntu side to Fedora. From a developer's point of view, the main difference, if I compare it to Ubuntu, is that they always get the latest packages, which helps them a lot. 

On the other hand, with Red Hat Enterprise Linux, I understand that it's set up to prioritize security. But sometimes, from a development perspective, it's challenging for them to obtain the latest packages. As an assessment, I have to go out there, fetch the package or compile the new package for the new version, and then bring it into Red Hat Enterprise Linux so that developers can use it. I think that's the issue. It's a balancing act between trying to get the latest package versions and ensuring stability and security. It's a problem that I think everyone struggles with.

Overall, I would rate the solution an eight out of ten because there is always room for improvement when it comes to technology.

We need to build a lockdown version of Red Hat Enterprise Linux to build our application on top.

It gives us a stable and secure platform on top of which we can build our applications.

We use Red Hat Enterprise Linux for containerization projects. It allows us to do better application isolation using containers. If I want to take a program that runs on my system and put it in its own network namespace, I can put it in a container. I can put a physical interface in with it and run them together in that container.

It definitely makes it easy to go back and look at all the Open CVEs and things like that.

It works well for us in terms of the portability of applications and containers for keeping our organization agile. We are able to do the kind of things we need to do. We are able to modify the system to do whatever we need to do to get where we want to go.

Things like packaging and the stability you get from things being downstream are valuable. A lot of times, upgrades are more security-based and not feature-based, so things do not break API-wise as we go forward a lot of times.

I feel like it is going all over the place now. Sometimes it is hard to figure out what is going on. I would like more guidance.

We definitely spend a lot of time developing on top of things, but I am not sure what on the Red Hat Enterprise Linux side can be better.

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

It is very stable.

It is very scalable. I would rate it a ten out of ten for scalability.

It has been great when we needed it. We have not needed a lot of it, but we have had no problems when we needed it. 

Positive

We did not use a similar solution previously. We have only been using Red Hat Enterprise Linux.

We use it on-premises. We use the ISO installer. We install it via CD ROM on-site.

I was not involved in its initial deployment.

It is the guarantee that we are getting the updates that we could backport into the system and we have a stable system to build on.

We have been using Red Hat Enterprise Linux since I have been with the company. They might have evaluated other solutions before I joined.

To a colleague who is looking at open-source, cloud-based operating systems for Linux instead of Red Hat Enterprise Linux, I would ask, "Why?" We plan to stick with Red Hat as far as we see in the future, and we have no plans to change.

Red Hat Enterprise Linux has not helped us to centralize development. It is not something we are looking to use it for.

We use Red Hat Insights very little. We work mostly in an offline environment. It is hard to use Red Hat Insights in an offline environment.

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

We are a Red Hat Enterprise Linux partner and provide host servers for various applications, including web applications and databases.

Red Hat Enterprise Linux's built-in security features simplify risk reduction and compliance maintenance, making them easy to use. We utilize SA Linux, a highly secure operating system. Its risk mitigation and compliance measures are effectively implemented due to the regular delivery of patches, updates, and bug fixes. This continuous maintenance enhances the stability of the system.

We are able to maintain compliance when it comes to the security regulations.

The level of portability succeeds in keeping our organization agile.

We used several platforms, but Red Hat provides us with a more uniform installation process, a more consistent platform, and easier system maintenance. Additionally, the Ansible playbooks are now simpler to manage due to the standardization of our platform. We quickly realized the benefits of adopting a single platform instead of using multiple platforms. This decision has streamlined our operations and simplified license management for our sales department. Additionally, the purchase process has become more straightforward.

We operate a hybrid IT infrastructure consisting of both on-premises and cloud servers. We have had positive experiences with Red Hat Enterprise Linux, which has enabled us to build and deploy applications with confidence and ensure their availability across physical, virtual, and cloud environments.

Red Hat Insights is a valuable tool for preventing emergencies caused by security vulnerabilities, non-compliant configurations, and unpatched systems. Although we haven't faced an emergency yet, we've noticed that the tool provides valuable advice and sometimes even playbooks to resolve security and stability issues. It's a powerful tool indeed.

Red Hat Insights provides us with vulnerability alerts and targeted guidance. All systems are stable and we have no crashes and no failouts.

Red Hat Enterprise Linux's most valuable attribute is its stability.

A targeted package tailored for small and medium-sized businesses can help increase business.

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

Red Hat Enterprise Linux is stable. We have been running the solution for years with no crashes.

Red Hat Enterprise Linux is scalable. We have not encountered any issues. Since we are virtualized, it is merely a matter of allocating virtual CPUs, virtual memory, and so on. The limits are very high, so we are not currently experiencing any constraints.

The technical support is good.

Positive

We switched from our previous solution to Red Hat Enterprise Linux because of the uniformity of the platform. It is also a larger organization that is well known.

The initial deployment is straightforward and well-documented. The deployment time is between 15 to 30 minutes.

I would rate Red Hat Enterprise Linux eight out of ten.

From what I've seen of Red Hat Enterprise Linux, it's well-documented. There are comprehensive notes and documentation available. I've been using it recently, and I've found that all the information I need is readily available. If we can't find what we're looking for, our support organization is there to help.

We have a virtual environment and deploy the solution from a satellite.

Currently, we require two people for the maintenance of Red Hat Enterprise Linux.

We are using Red Hat Enterprise Linux for running solutions, such as database solutions, and enterprise, web, and network applications.

One of the fundamental reasons Red Hat 7 has benefited our organization is that it is fully certified. It has certifications on the DISA STG and other cybersecurity frameworks like Zero Trust. This is what the Department of Defense mandates to be used and it is feasible to receive these specifications and automate the implementation for continuous improvement. By implementing the technical guides, we can receive immediate results and protect environments according to our expectations. There are a group of technical procedures that are shared and that you can implement, if you follow the industry best practices.

The most valuable features are the specification and technical guides, they are most important for cyber security assurance

The accessibility to the resources could be more widespread. The registration of the license information is complicated and this product registration process should be easier for customers to access.

In an upcoming release, they could improve by having more focused security.

I have been using Red Hat Enterprise Linux for more than 15 years.

The solution is highly stable.

Red Hat Enterprise Linux is perfectly scalable. You have some resource limits depending on how you're using the technologies. According to those usage patterns, the system is going to be able to give more or less. However, this depends more on the user side than on the system side.

We have approximately 10,000 enterprise users using the systems. They sporadically log into the applications and make use of the database systems and extract information. 

There is a division between the paid support and the support that is included by the website of Red Hat. I have only used the website support and there is a lot of documentation available.

Positive

I have used other Linux products, such as AWS Linux, Debian Linux, and Ubuntu.

The initial setup is straightforward for our use case. As long as you understand what you're doing, the technologies that are involved, the proper way to style, secure, and prepare them, everything will be fine.

After you have the guide, the printed procedure, the deployment is straightforward. The operating system can be deployed in less than an hour.

Okay, and how long did the deployment take?

The solution requires maintenance, and it is a shared responsibility. They take different maintenance actions or tasks, and sometimes it's the operating system, database system, or application front band that needs maintenance.

The number one advice would be to keep the division between testing and production.

There's one system that you need to set up for testing purposes only, and this testing system can be obtained free of license. There's an evaluation license that can be easily applied. When developing the application on the Red Hat 7 system, stay using the evaluation version until the requirements are fully met, only then should you migrate them to a paid supported version.

The biggest lesson that you learn by using this solution is, you easily reach a point where a single person or a single team can no longer respond to the complexities and challenges of the security or the different versions of the applications. At that moment you need to rely on a serious fused team, that team that is backing the effort.

I rate Red Hat Enterprise Linux an eight out of ten.

I use the solution to build web applications.

The tool provides more support, resources, and documentation than other products.

The product is super easy to use.

The default settings are confusing. I often change these settings to avoid problems.

I have been using the solution for a couple of years.

The stability of the product is very good.

I did not have issues finding configurations and changing settings as needed. I haven't had any issues like bugs or downtime while using Red Hat Enterprise Linux. Overall, it was a good experience. Overall, I rate the solution an eight out of ten.
