Red Hat Enterprise Linux (RHEL) Reviews

We have RHEL deployed on the Cloud and also on-premises. We purchased it from a Red Hat representative.

We have several use cases, one of which is in the manufacturing field. In this case, we leverage manufacturing data for R&D engineering workflow purposes. Specifically, we use the HPC workload to visualize the utilization of all compute nodes as a percentage. RHEL also finds application in the automotive industry for specific engineering workloads, including drivetrain simulations, design processes, crash simulations, and driving simulations. Additionally, RHEL is used in the healthcare industry, particularly by highly regulated pharmaceutical organizations, to manage healthcare licenses.

Red Hat Enterprise Linux has provided significant value to our organization through its robust support, extended lifecycle, and valuable insights through the analytics tool that helps to identify and remediate potential issues before they impact the organization. We haven't encountered any Windows operating system that offers a comparable lifecycle length. By analyzing incidents in our management tracker, we were able to realize the benefits of implementing RHEL. For example, we conduct monthly reviews where we examine reports to identify any incidents that have occurred. Following the implementation, we utilized the ticketing tool to analyze incident data and observed a 15 percent reduction in incidents.

Red Hat Enterprise Linux offers several valuable features, including robust security, a subscription-based model that offers comprehensive support for development and distribution, and an extended lifecycle for stable operation.

One area for improvement in RHEL is compatibility with some third-party tools, like those offered by Intel.

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

RHEL is a stable solution. The maturity of the OS helps with the stability.

RHEL is a scalable solution.

The technical support team is knowledgeable and meets their SLAs. If the first level cannot resolve our issue, they will escalate the ticket to the next level until it is resolved. They take ownership of the ticket until it is resolved.

In addition to Windows and Linux, we also utilize Ubuntu depending on the specific product and industry. While any operating system may be suitable for the manufacturing and automotive sectors, regulatory environments like banking, finance, and healthcare require heightened security, encompassing the operating system itself.

Deploying RHEL directly is straightforward, but integrating it with third-party tools requires expertise in both the OS and the specific tools being integrated.

Red Hat Enterprise Linux can be deployed quickly on individual machines.

Red Hat Enterprise Linux provides a golden image builder. This tool allows us to deploy the same image across all compute nodes in the cluster, ensuring uniformity. While we may encounter occasional compatibility issues with specific hardware, we have workarounds in place to address them.

The implementation was completed in-house.

The operating system serves as the foundation for our hardware interaction, contributing to a strong return on investment.

While purchasing a small number of Red Hat Enterprise Linux licenses can be expensive, acquiring licenses for our entire ecosystem or environment often leads to better pricing.

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

Organizations seeking to reduce costs associated with RHEL support or those with internal teams capable of managing and supporting the operating system can leverage the open-source version.

Our system administrators handle maintenance, and we additionally cover annual maintenance costs.

I recommend adhering to best practices and maintaining the system regularly for optimal stability.

We use Red Hat Enterprise Linux across different versions, from six to nine, to run various applications. Our main area of focus involves using Satellite support to manage and patch both the Red Hat Enterprise Linux OS and specific applications like OpenShift and other products supported by Red Hat. We have multiple environments, including Azure, AWS, and a standalone eXs host. 

Red Hat Enterprise Linux's patching process needs improvement, particularly in achieving consistency. Currently, when you patch, you might not have control over the timing, leading to different software packages ending up at different patch levels. This lack of consistency can make it challenging to manage and control the various components effectively. My background is in IBM AIX, so the patching is based on the technology level and the service pack level, so all the related patches stay at the same level.  

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

I would rate the knowledge base offered by Red Hat as average. I would rate their support as a three out of ten.

Negative

We also use IBM AIX. I prefer AIX, but Red Hat Enterprise Linux is cheaper. However, IBM has real technical support. You can call a 1-800 number and get a technician on the line. That's real technical support. Red Hat requires you to email them and schedule a call. 

Overall, I rate Red Hat Enterprise Linux as a five out of 10. 

I don't see Red Hat Enterprise Linux's built-in security features as effectively simplifying risk reduction and compliance. We use AIX, but still, we face a lot of vulnerabilities from Red Hat that need frequent patching, often monthly. This frequent need for updates, along with the rapid changes in Red Hat Enterprise Linux releases, can be frustrating and lead to instability. In the banking industry, where we take vulnerabilities seriously, these frequent releases and lack of stability can be problematic. 

We have general use cases.

It's a well-supported OS. I don't know what we'd use if we didn't have it.

Moreover, the last time I had an issue flagged with the vulnerability, I was able to go to the Red Hat website and find a patch. It worked pretty well.

The built-in security worked well when it came to solidifying risk production and maintaining compliance. The uptime or security of our systems has been pretty solid.

It helps us maintain our security standards and keeps us up to date on security. 

One of the most valuable features is the package manager because it makes it easier to keep everything up to date.

The package compatibility between different releases is a little confusing sometimes.

I have been using Red Hat Enterprise Linux for 10 years. 

We've also used Ubuntu. 

It's a matter of certain servers that need to be kept secure, so we chose Red Hat. 

When I order a server in our organization, it comes installed, and then they spin it up.

I am involved in the upgrade processes. The upgrades weren't complex but required some downtime. We don't normally upgrade until a particular OS version becomes end-of-life and the new one starts.

Our in-house IT department did the deployment. We have a separate IT department that leverages the training provided by Red Hat.

Overall, I would rate the solution a nine out of ten because most of the information I need I could find on the Red Hat website.

We use Red Hat Enterprise Linux as an operating system for hosting Oracle databases.

Compared to Windows as a server operating system, Red Hat Enterprise Linux seems more secure, and we've had fewer intrusions onto our systems. That one, for us, is the single most important thing. In a few instances where we've had intrusions, we've been able to detect them very quickly and get patches that fix those security holes very quickly, thus preventing further intrusions.

In the cases of clients I've worked for, I've never been involved in a ransomware attack or a significant reportable data loss. That is why we continue using either Red Hat Enterprise Linux or Oracle Linux.

The most valuable features are its stability and resilience in that we rarely have to take down the systems completely to patch them.

The operating system configuration and function selection could be improved. Configuring the operating system and selection of options takes a lot of expertise. I'm now going to retire, and I've been doing this for many years. Trying to train people to make those choices is proving to be difficult. However, to get applications to run efficiently in those environments, those selections are absolutely crucial.

Red Hat Enterprise Linux should include simpler storage management.

I have been using Red Hat Enterprise Linux for 20 years.

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

No system is infinitely scalable in a linear manner. As you scale up anything, the fact that you're scaling adds overheads. If I were to compare Red Hat Enterprise Linux to Windows, I would give Windows a seven because you run out of scalability much faster on the Windows side.

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

Red Hat Enterprise Linux's technical support team is not that great.

Negative

Red Hat Enterprise Linux is expensive, but it's hard to quantify. Oracle doesn't have a license. You just download Oracle software and use it, but their support is way more expensive. So they're about the same. With these types of operating systems, you need to have some support. With Red Hat Enterprise Linux, you need to pay a massive upfront licensing fee in order to get support. You don't have to pay a licensing fee for Oracle, but then you pay a massive support fee to get the support.

They're about the same overall. I don't really make that choice for my clients. I ask them to ensure that they do have some support from someplace. If they suffer a breach and need someone to help fix the problem, they should have something up and running when it happens instead of running around trying to arrange it.

Most of my clients have particularly sensitive information. We tend to run on-premises rather than the cloud because of security issues for those highly sensitive databases. We disconnect those databases from the internet so they are ultimately secure. That is something that you cannot do in the cloud.

Red Hat Enterprise Linux doesn't have any particular standout security features, which the other Linux tools don't have. I've also used the Oracle version of Linux, which seems very similar to Red Hat Enterprise Linux. Both seem to be as secure as the other. If I have to give a score in relation to stability, Oracle's version of Linux might be slightly more stable than Red Hat Enterprise Linux.

All the customers I've worked for have been using those operating systems for a long time. For instance, one of our customers has been using Red Hat Enterprise Linux since it was first available over 20 years ago. A return from that is difficult. They were using Unix rather than Linux. The applications they ran were ported from those environments, and migrating them to Red Hat Enterprise Linux was relatively painless. We did those migrations back in 1995 to 1997.

We tend to use the environment for running databases. So, we have very few real users directly connecting to the system. The people who connect to the system do so by applications.

We haven't needed any maintenance for a long time. My last company was a large organization, and we had the internal expertise to provide support. Some net contributors have fixed bugs themselves and contributed those bug fixes back into the Linux open-source community. It was a huge organization, and its IT department was as big as some software consultancies.

Overall, I rate Red Hat Enterprise Linux a six out of ten.

The solution offers stable distribution and is very focused on security. It's very committed to delivering security fixes. That way, we don't have to keep moving forward with new versions. 

They are very focused on security and their products are well-designed in that regard. Their delivery of fixes for all products is great. It helps us maintain compliance and helps with risk reduction.

They provide satellites as an account management solution to deliver fixes. It helps us figure out where there are security gaps in our system. They offer good compliance out of the box.

We are starting to roll out container approaches for delivering new solutions. It's still early. We are using a very simple setup and we're beginning to test OpenShift. 

The product enables us to achieve security standards certification.

We can build with confidence and ensure availability across physical infrastructures. From the OS perspective, they do have a lot of reliability features. The virtualization is being phased out (their previous solution) and now they are moving to OpenShift. We're just starting to adopt it. 

We can automate security configurations. We're using the Red Hat security ecosystem to manage logical access and security. It delivers a lot of information with regard to security and hardening and how to use its products properly with regard to security, and we try to follow those guidelines. 

Overall, they are doing a good job. We're hoping that they continue to onboard open-source products into their operating system.

I've been using the solution for about seven years.

Technical support is pretty good. It's one of the main reasons we chose Red Hat over competitors. 

Positive

We've been working with CentOS. It was used in a very limited scope. We've also used Oracle Enterprise Linux for a limited scope. Red Hat has a more solid community and certifies its products more effectively. 

We're quite experienced with the initial setup at this point. For us, the process is a standard procedure.

The product does require some maintenance. There are about four people dedicated to the technology at this time.  

They are becoming very competitive. There has been more pressure based on competition, which is healthy. They could continue to work on their pricing model. The subscription model for some products needs improvement. The automation shouldn't be combined with managed hosts. Pricing should be based on socket and not endpoints. 

We evaluated Oracle Enterprise Linux. 

I'm a customer and end-user. 

We do not use Red Hat Insights just yet due to some restrictions around sending sensitive information off-premises. We're quite limited in terms of using that feature at the moment.

I'd rate the solution nine out of ten. 

I use the solution for research purposes. 

The solution provides more detailed control. 

The product's built-in security features when it comes to simplifying risk reduction and maintaining compliance can be a tedious topic. It varies from user to user, however, it offers a lot of rapid releases. It helps us to simplify risk reduction and maintain compliance.

The portability of applications and containers built on the product when it comes to keeping your organization agile is good. It's easy to use.

It enhances our security. It helps us comply with company regulations.

When it comes to ensuring availability across physical virtual and cloud infrastructure, it's been okay so far.

It helped us to avoid emergencies due to security issues.

I consider the solution to be sufficient. I do not use it too much and therefore do not see any underlying problems with the solution. 

It's sufficient and it doesn't need new features. However, as new technologies enter the market, I hope they will keep up with the changing market.

From a product point of view, it's very efficient for servers. However, the solution is complex in terms of its architecture. It could be simplified. I'd like to see them introduce PDFs or documents to better explain technicalities to new users. 

Memorizing commands can be a bit tedious.

I've been using the solution for two years. 

The product has been stable so far. 

The solution is deployed to the data center, which is managed only by a few teams. 

About 150 people are using the solution. We also have 45 to 50 administrators as they are managing different areas.

The solution is scalable. However, I'm not sure if we plan to scale further in the future.

I have not interacted with support very much. 

I was involved in the deployment. The initial setup was very straightforward.

The deployment is fast and the process is efficient. 

I did a lot of the implementation myself. 

I did not evaluate other options. 

I'd rate the solution an eight out of ten. 

I'd advise new users to learn from someone who has done everything before. It's much easier than trying to learn by yourself from scratch. They should also have their own environment for testing. 

We use Red Hat Enterprise Linux for servers. We have deployed application servers and database servers on it. We run Oracle Database, WebLogic, Apache, and JBoss on it.

Red Hat Enterprise Linux is very important for our organization. We are very sensitive to security.

It is not difficult to move workloads between the cloud and the data center using Red Hat Enterprise Linux. Mostly, our teams use file servers centrally, and then they use scripts so that it is done automatically in the background. Initially, they may get problems while connecting due to the security or firewall, but once the connection is established, we do not see any problem with that.

Red Hat Enterprise Linux has helped to avoid cloud vendor lock-in. I am not sure how much our organization has saved in costs by avoiding cloud vendor lock-in, but we would have saved a good amount.

It is very stable and robust. My team is very comfortable working with it for all end-to-end activities. They can work with it very easily. They prefer working through the console rather than the GUI.

Its resiliency is good. There is no doubt about that.

I don't prefer Red Hat Enterprise Linux for desktop over other options. 

I have been using Red Hat Enterprise Linux for a good amount of time. It has been eight to ten years.

It is very stable. I would rate it a ten out of ten in terms of stability.

It is very scalable. I would rate it a ten out of ten in terms of scalability. It is highly available and scalable for servers.

It is good. I do not see any challenges. I would rate their support a nine out of ten.

Positive

We choose an operating system based on the needs and the use case. We use different operating systems for different purposes, so they are not comparable. For example, for desktops, Linux is not the best. For desktops, Microsoft Windows is the best. Similarly, if you are using any Microsoft products, such as SQL Server, Microsoft Windows is the best option. However, nowadays, we also have Microsoft products installed on Linux.

I am not involved in its deployment and maintenance. We have a separate team with 40 to 50 people around the globe for that.

We most probably have both on-premises and cloud deployments on a private cloud, but I am not sure. Our infrastructure services team takes care of that.

We have got a good ROI, but I do not have the metrics. I would rate it an eight out of ten in terms of ROI.

Its pricing is good and competitive.

I would recommend it based on the use case and the budget. If it meets your needs and budget, Red Hat Enterprise Linux is the best option.

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

RHEL is a phenomenal operating system for three primary reasons: 

• Support compared to the rest of the Linux ecosystem
• Cohesive ecosystem 
• Application platform

The combination of these three aspects has proven to me from an advising perspective that it is key in decision-making.  

Our clients purchase the use cases via cloud provider and hyper-scale. It's a combination of both. Mostly, new clients prefer going for hyper scalers. Whereas the clients with Red Hat licenses, predominantly those from the banking sector, transfer the licenses to the cloud depending on their hyper scaler plan.

The main benefits my clients have seen are the supportability, maintenance of the operating system, security, and the ecosystem that ties it all together.

The solution has a phenomenal operating system. Its support features are best compared to the rest of the Linux ecosystem. Generally, applications don't rely on operating systems per se. When combined with the container ecosystem, security is the paramount feature that is most asked for.

The problems our clients try to solve by implementing Red Hat Enterprise Linux vary. The main ones include containerization, cloud transformation, and visual transformation in terms of how you get to the cloud in a hybrid mode. The key aspect that I give advice about is how for the operating system in terms of the scalability to bridge the cloud to the on-prem world, so where they could have the OpenShift ecosystem that it runs into and helps them manage both systems together. 

The solution's operating systems are phenomenally resilient and stable. The good part is that Red Hat has backing and support. Also, combined with IBM, it gives more confidence to my customers.

The solution's ecosystem is good but it would be better to create cohesive components in all of the development tools. 

A developers' hub feature would help. 

OpenShift already provides excellent visibility, but bridging the gap with Kubernetes would be key because Red Hat Enterprise Linux drives OpenShift.

I'm a big open-source user. I've been using different forms of Linux for quite some time. For my enterprise purpose, I use the RHEL for other purposes and a few other different Linux operating systems. We have been using Red Hat Enterprise Linux for more than ten years.

I have experience working with Ubuntu, Fedora, Canonical, etc. From that perspective, the solution's stability is good. The security feature plays a key role in terms of the pace at which it receives updates for operating systems to maintain it.

In terms of the architectural perspective, the nature of the solution is scalable.

The solution's technical support is very good. My clients generally manage it, and I have received positive feedback. They have a responsive support organization to communicate with.

I have used Canonical and Ubuntu. In comparison with Red Hat Enterprise Linux, Ubuntu's ecosystem consists of multiple operating systems and container platforms like MicroK8s. The partnership with hyper scalers in terms of deployment is one of its benefits as well. On the flip side, it has some drawbacks regarding licensing and export control, where Red Hat shines well.

The solution's pricing and licensing are good. Although the open-source space is becoming more competitive, Red Hat brings value in terms of support. At the same time, different operators like Canonical Kubernetes are catching up. Thus, the price would become the differentiation factor regarding packages for support, and container ecosystem combined with Ansible. All these key elements would add more value to the pricing.

The solution's key element is its cohesive ecosystem between hybrid and cloud environments. It helps clients such as giant banks create a single space for managing workloads in different hyper scalers. This way, it helps in cost management and visibility. It creates a single platform to manage work. It helps in saving costs, especially with subscription plans. It provides them with a consistent cost structure. Also, being an open-source solution has benefits that fit within the ecosystem.

I rate it an eight out of ten, primarily for the support and licensing terms. It helps some of our enterprise clients navigate open-source licensing and export control complexities.

There are areas of improvement, such as the cycle of updates and the ecosystem as a whole. Also, the elements like Ansible are priced separately. For automation, there is an opportunity to combine everything. Even though they are different products, they shouldn't be charged separately from the ecosystem perspective.

We use the solution majorly for JBoss, Apache, Java workload, and Comcast. We also use it for Apache Sattelite to do all the patching and database management. We use it for almost everything. We were a pure RHEL shop, up until recently. 

The most valuable feature is Satellite. Its consistency in patch upgradation is great. For the ten-year lifecycle, we have been able to rely on it and not worry if the patch will break. We do not need additional patching features since it covers everything.

The Modules feature is awesome but it could be even better.

We have been using the solution for 25 years.

The solution is stable. I have never remotely questioned its stability. The downtime is rare. It is usually a vendor's application issue unrelated to it. 

My company only has one complaint; we have been using it for more than seven years out of its ten-year lifespan and have yet to receive any version update. The drivers have become stale. We are trying to upgrade them manually. It would be nice if they had updated the drivers. If they do not update them, the solution will end soon. They should prevent it from crashing every time we try to update it. We are still rolling Ansible to automate some of the functions but, it is complicated to process with a vast sync of firmware and drivers.

The solution is scalable. I am a Satellite owner and we've had scaling issues with it. Those issues are mostly because my company didn't make it scalable in the right way.

They have their own expectations of how to make something highly available. And Satellite doesn't fit into that. 

I rate the solution's technical support as nine out of ten, as there is always room for improvement. I never had an issue with the support services. It is good and worth the value. 

I don't usually put up a ticket for every minor error. I am an expert and know the technicalities required to resolve the issues. So, whenever I contact them, I expect it to get somewhere. Because most of the time, the executives put more than one problem in the same ticket unrelated to another. It becomes more complex and confusing.

Positive

Red Hat Enterprise Linux generates a return on investment. We have everything on it. We have Windows servers for SharePoint and multiple cloud providers as well. In addition, we have OpenShift and Docker Enterprise, and some other open-source applications.

The solution is a good value for money. They keep adding up essential features to the specific subscription plan. I am also not a big proponent of top-level open-source applications as they do not provide support services. Whereas, with Red Hat, I can call them for queries and get answers immediately. In comparison, open source doesn't have that facility. Even if you hire a support vendor, they just give their opinions and try to help but they don't own the project.

At the end of the day, we have a 999.99% reliability of only 20 minutes a year of downtime with Red Hat. It is impossible to get that with open-source vendors as sometimes the applications might break if it doesn't notify about the changes on time. Conversely, Red Hat Enterprise Linux has a ten-year life cycle assurance, so we don't have to worry much. Also, we are in a TAM program. Thus, we can call the support team immediately for any issue.

Our organization constantly evaluates other options, as Red Hat Enterprise Linux's cloud version doesn't offer new features. Other than that, we go back and forth using Centralized and Rocky Linux. We prefer the ones we don't have to pay for the licenses.

It has a strong security posture. I did a SELinux contract for my current company. Compared with open-source alternatives, Red Hat Enterprise Linux provides better support services and reliability. Also, we are rolling out a new Ansible platform for insights. It gathers information about how many jobs we have, how long they take to complete, etc.

We need to manage vulnerabilities for a massive base of clients' systems. We don't use open-source apps for it like Red Hat. We have a third-party tool as we straddle different compliances. However, Red Hat is great about security announcements. I can call them anytime for an update as well. But it is challenging to work with the vendor for scanning machines. It does not know how to work with Red Hat packaging version numbers.

I rate the solution a nine out of ten.

We prefer Red Hat Enterprise Linux as our operating system due to its excellent support. If a business wants something, we deliver it and we prefer a Red Hat Enterprise Linux-based system because of the support. It can be a simple application to a big system. It doesn't have pre-defined roles. It's a go-to operating system. 

Our use cases for it vary from plain operating system management to handling specific tasks such as running Oracle databases or other similar applications. They include quite a broad spectrum of requirements. Also, they are not limited to predefined roles but encompass the entire operating system infrastructure.

The solution's SELinux feature is a gold standard for security. It also has the best ecosystem. 

In addition, its automation platform, ITM, is a good product and works well for us.

Some of the solution's features need to be automated. We encounter the hassle of registering the system and attaching a subscription. Our company has development teams, and we have to develop subscriptions for them. Here, having the solution up and running on the developers' machines is a bit of a hurdle. Although we can run it on platforms like Red Hat Connect but, it needs to be somewhat more accessible so developers can just download it and start with the work.

I have been using the solution for 10-15 years.

The solution is stable.

The solution is scalable when combined with automation features. I rate its scalability a nine.

The solution's customer service is good.

Positive

I have used Ubuntu, Fedora, CentOS, and macOS. Initially, I worked as a Red Hat Certified Administrator in RHEL 5. Later, I began to work for its partner company. That is how I switched to the solution. It was not a conscious choice. It just evolved that way.

The solution's initial setup process is straightforward. You have to follow the steps, copy the template and multiply it.

The solution's price is reasonable. If you have a license for the support, they provide excellent services. The support team is always available for help in case of errors or system downtime issues.

RHEL’s built-in security features for simplifying risk reduction and maintaining compliance are good. If you keep SELinux on, it is all good. If you have a system with SELinux off for a long time, it could get you in trouble. The system will make many changes, like restoring files could break your application later. In case you resolve the problems simultaneously, it is fine. 

The troubleshooting feature of Red Hat is excellent. It can solve many issues on the machine right away. In addition, if you have an external scene, then Red Hat Insights is on. I sometimes go to this feature to see its status and what is happening. 

I don't do this on a daily basis and only check it every two weeks, but it's nice to have. I mainly oversee the high-level view of all the systems. This way, I know if the clients' machines need a patch system. 

There are some missing modules for SELinux in Ansible, like the playbook. It becomes a genuine hurdle to manipulate SELinux at the moment. I have to go to the machine, take a file to the repository, and deploy it.

I rate the solution a nine out of ten.
