Red Hat Enterprise Linux (RHEL) Reviews

My main and only usage of Red Hat Enterprise Linux is for the on-premise workload. We use it for running Red Hat Ceph Storage and running automation using Ansible. Other than this, I use it for doing any auto test that I would like to do on a Linux-based machine.

From a security perspective, the most valuable feature is SELinux. SELinux provides good security. It's doing a good job of protecting my real estate.

The portability of applications and containers built on Red Hat Enterprise Linux is great.

It has its own ups and downs. Most of the time, it's pretty stable, but sometimes, you'll find some weird bugs that could affect the availability of your running machine. Red Hat can improve its operating system by making it better from the quality assurance perspective. Users do find bugs, which they, of course, shouldn't encounter. A better QA would probably make the job a lot better. It would make the product a lot more stable than it's today.

I've been using Red Hat Enterprise Linux for over three years.

It has its own ups and downs. The operating system itself is pretty much stable, but there could be some bugs that could affect your availability. While running the Red Hat Enterprise Linux operating system, I did experience some bugs from time to time that did affect the availability on my machine.

Overall, it's pretty stable, but when you do something more hardcore or special, then its stability could be affected. I can't recall anything that I faced in the last few weeks or months, but as you go around production with Red Hat Enterprise Linux and have lots of machines running on it, you can get stability issues or kernel issues. A machine might suddenly be rebooted for no reason. That's my experience with Red Hat Enterprise Linux's stability.

It's deployed at multiple locations. Approximately, there are 200 people using this solution.

The support in Israel from the guys sitting in Israel is great, but when contacting the support engineers across the globe, the support level just decreases, and the reliability decreases as well. The support guys locally in Israel are great, but the support guys worldwide aren't that reliable. Overall, I'd rate them a seven out of ten.

Neutral

I used Ubuntu and Fedora, but mainly Ubuntu. Ubuntu was a great operating system. We had to change from Ubuntu to Red Hat Enterprise Linux due to subscriptions. The enterprise had more and more need for container orchestration, so we ended up purchasing the Red Hat OpenShift container platform, and the use of Red Hat Enterprise Linux in the organization grew significantly.

The security features of Red Hat Enterprise Linux are aligned with the entire industry. They do not have any higher advantage over other competitors, such as Ubuntu from Canonical, so security-wise, it's okay.

It was pretty much straightforward. Deployment of the Red Hat Enterprise Linux operating system didn't take longer than two days.

It was deployed in-house. Three to four people were involved in its deployment.

In terms of maintenance, it just works unless you do anything special with it.

It's pretty expensive, but I'm not familiar with the pricing of other vendors for their operating systems. I'd rate it a seven out of ten in terms of pricing.

Red Hat Enterprise Linux's main advantage is the support that you get by purchasing their subscriptions. 

We looked at OpenSUSE, but we eventually ended up with Red Hat Enterprise Linux because of the support that Red Hat has in my country. In Israel, Red Hat is a lot bigger than OpenSUSE, so we ended up going with Red Hat Enterprise Linux because of the available support in the country.

If you're evaluating this solution, I'd recommend having your own architects discuss your architecture with the local Red Hat personnel in your state. Red Hat Enterprise Linux is a good product, and it could be even better if you know how to integrate it based on the preferences of your organization. So, my advice would be to have your guys discuss your IT architecture with the local Red Hat people and then decide how to specifically integrate your IT infrastructure with the Red Hat software.

Overall, I'd rate Red Hat Enterprise Linux a seven 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.

We use Red Hat Enterprise Linux for OpenShift. We run KVM and then deploy OpenShift under it. Additionally, these are my customer's use cases. 

We run it in-house for prototyping applications. Moreover, my customers utilize it to port older Solaris applications to Linux. I also use Linux on Z.

The customers would benefit from quickly identifying vulnerabilities as they arise and being able to fine-tune machines if certain features are not properly fine-tuned. 

Since we use it for virtualization, KVM has been quite valuable. It's been very solid running OpenShift under KVM. The toolset has been pretty good.

By implementing Red Hat Enterprise Linux, the customers were getting off older hardware like Solaris. They're trying to migrate their applications off those boxes and also cost savings. They were migrating over to consolidate onto Z.

However, none of my current customers use Red Hat Insights. I'm trying to encourage them to adopt it, but since they operate in air-gapped environments, Insights needs an internet connection. I mainly work in the Federal space.

Personally, I like the terminal-based tool called Tusa for certain activities. Sometimes we just don't have a web interface available for repetitive tasks. It would be nice to have a web-based tool for Red Hat Enterprise Linux since we don't always have access to a web browser.

The stability of Red Hat Enterprise Linux is solid. It performs well and handles the workload effectively.

It scales well on my platform. We are running OpenShift and other machines on it, and it scales without any issues. Although, it's largely due to the platform itself.

The initial setup can be complex in certain cases, particularly when dealing with a fed customer that operates in an isolated environment. But, in other installations, it has been mostly straightforward. Red Hat Enterprise Linux could still work on making it a little more streamlined in terms of deployment.

There have been some issues we've had with portability, picking it up and moving it somewhere else.

In terms of simplifying risk reduction and maintaining compliance, Red Hat Enterprise Linux is good. The customers I work with don't use them extensively. However, during the machine building process, we apply some security features at build time rather than later on. We take measures such as applying a stake during the build process. While I keep pushing the customers to use the provided tools, some of them operate in air-gapped environments, preventing them from accessing the internet for the latest rules.

The portability of applications and containers built on Red Hat Enterprise Linux is pretty good. We actually build applications on one platform and successfully deploy them on another, so that's pretty good. Overall, using Red Hat Enterprise Linux is definitely a strong set for my customers.

My customers definitely see an ROI. Especially when running it on Z platforms due to fewer processors and, consequently, fewer licenses required. They have experienced a return on investment. 

When I previously worked in a Linux shop using Tusa, it was more expensive. But I think Red Hat Enterprise Linux has become more competitive, particularly for Z platforms.

One example is the consolidation of their infrastructure, getting off of Solaris, and not paying high maintenance costs. Consolidating onto Linux, specifically Red Hat, has been helpful for one of my customers.

There are not many choices available on the system they use, probably only two or three options. Red Hat Enterprise Linux is the preferred choice, especially since it is widely used in the enterprise.

The other two choices are SUSE and Ubuntu, which are commercially available systems. Honestly, no one is going to use Ubuntu because it's not popular enough. So it's really a choice between SUSE and Red Hat Enterprise Linux. SUSE has been around longer on my platform and system settings. But I think people are shifting over to Red Hat Enterprise Linux as it runs on Intel and is more enterprise-oriented.

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

We installed the product at a very large hospital as their underlying operating system for Kubernetes, but it is not OpenShift. We use it for one-off servers and lab machines.

Copious documentation is probably the best feature of the solution. If you have a lot of high-quality documentation in one location, it is easier to search and get exactly what you need. It's more efficient when I get stuck on a problem or need help configuring something. It saves us time searching through Google or looking through GitHub Issues to solve the problems. It is a top-notch solution.

If the solution were easier to use and understand, it would not get disabled as often as it does. The solution should be made more secure. The changes made to CentOS make it hard for somebody to spin up and test it without having a preexisting relationship and license. 

If somebody wants to get something going quickly and is trying to settle on Red Hat, they don't have a free version to go to. Ubuntu and SUSE provide such platforms to the users. It is one Achilles heel in Red Hat at the moment. 

Even if Red Hat would enable a full version trial for people to test it, it would be less than what others are doing. Others are giving it away for free until you actually need support, and then you can choose if you need to buy it. With SUSE you can install it with SUSE Leap. It's pretty much the same thing. When you want support, you must enable support, and it becomes SLES.

There's nothing in Red Hat where I can run along on the free version for as long as I need to, and then when I want support, activate support on the same product. I have to reinstall it if I want Red Hat. Even with CentOS, it still wasn't possible to just activate it for Red Hat and make it become Red Hat Enterprise Linux. That's been something that's long been lacking in the product.

I have been using the solution since 1996 or 1997.

I have no complaints at all about the stability of the product.

As time goes on, the solution gets better. It adopts new features. I would say that it does a pretty good job.

The few times that I've encountered support, it was great. I don't really go through support channels. However, when I reach out and ask a question to the people I know in support, I get answers pretty quickly. I find that they have a good deal of product knowledge.

Positive

When I first started using the product in the 90s, it was just Red Hat. So I used Red Hat, and I used IBM Slack. I've used quite a number of different Linux distributions. Red Hat Enterprise Linux has been around longer than Ubuntu. I still use other solutions along with Red Hat Enterprise Linux.

Typically, the initial setup is pretty straightforward. If it's virtualization, it is really easy because we have an image already, or we can create one. We can use Kickstart. I used to run a 5000-node HPC cluster in the early 2000s based on Red Hat Enterprise Linux. We used a combination of SystemImager and Kickstart for it.

It's the default posture of a lot of the third-party vendors that you should just disable and leave them off. With containerization being prevalent everywhere, portability is across the board. Red Hat Enterprise Linux adopted Podman as opposed to Docker. Podman is a good tool, and I like it. Red Hat Enterprise Linux is the standard on which many others have based their platforms.

Using SELinux is largely misunderstood. If used properly, it provides a great platform for us. Red Hat is a big corporation, and we have people we can reach out and talk to. The same goes for SUSE. For Ubuntu, I have always gone straight to NVIDIA for support. I personally don't know of any great differentiators between all the products. I know Red Hat. It's been around longer, and I've had a long history that makes me comfortable. 

I wouldn’t recommend one over the other. It would come down to the use case. If someone wants Kubernetes on-prem, I would probably guide them toward OpenShift. I do have customers that don't run OpenShift on-prem. I often find that the customers already have a preference because they already have a license. So it's never really a decision that falls on me.

Red Hat Enterprise Linux uses firewalls, so configuring a firewall is easy. I have deployed the solution in multiple places. Overall, I rate the product an eight out of ten.

We use the solution for deploying middleware applications and many different applications that we have, like the ones we can use in the marketplace with different users. We use other kinds of solutions in many of the applications we develop. But in general, we use Red Hat Enterprise Linux.

Benefit-wise, the product is very stable. The product is also very compatible, and many people want to use it.

There are a lot of features in the solution. Red Hat Insights is one feature that we rely on currently.

The model, specifically the consumption model, is an area that needs improvement in the solution.

We had a really big challenge striking a chart between on-premises and the public cloud. The approach is that you pay as you go in Red Hat Enterprise Linux. In general, you pay for whatever you use instead of preparing for a full year.

At times, language is a barrier when it comes to support. That's one of the aspects I would like to improve about the solution.

I have been using Red Hat Enterprise Linux for six to eight years. My company has a partnership with Red Hat Enterprise Linux.

Red Hat's support is good. Sometimes cases take a little bit longer to resolve. If you are clever enough to upgrade the case and put it at a very high level of priority, then it gets resolved faster. In general, the support is good. I rate the support an eight out of ten.

Sometimes, a customer doesn't speak English or we need people who speak Spanish for the case to be easier to understand. In those cases, we lose time. I can't push all my engineers to learn to speak English. My customers and our engineers speak Spanish.

Positive

We've been working with Red Hat Enterprise Linux since the beginning.

I was involved in the deployment a long time ago. The setup process is easy. The solution is also easy to use.

Regarding the time taken for deployment, we can do it with a machine at this moment using Ansible. In our orchestration, we passed more or less, creating one machine for Red Hat and the entire environment. It took us eight days and an hour. At this moment, we can deploy it on a machine in an hour with all the security. If a developer comes to us and tells us that they need a new machine or new instance, we can provide that in an hour on-premises. In the cloud, we have to use a lot of tools.

I have purchased the license via hyperscalers and transferred it as well. I purchased the license from the marketplace and also from Red Hat.

Pricing is something that can always be better.

We have not evaluated other options since we trust Red Hat Enterprise Linux.

I am running my workloads on-premises and on the cloud. I mainly use AWS.

Resiliency-wise, the solution is very good. It's good because we don't have a problem with our environment at this moment. When we don't have a problem, we don't need to explain what is to be improved in the solution. It is reliable and doesn't break or bring us any problems.

Regarding how easy or difficult it is for me to move workloads between the cloud and my data center using the solution, we don't have problems. In general, it's easy.

We are talking about moving applications from on-premise to the cloud. We need to see if that represents any cost savings. We would need to go through a migration process, and that would be an extra cost.We would need to see if that is beneficial.

I rate the overall solution a nine out of ten.

We are running our critical applications on it. We are using versions 7, 8, and 9, and we are running our workload on private clouds. We are currently testing Azure, but we don't have the production workload on it. 

By implementing Red Hat Enterprise Linux, we wanted to solve some of the reboot problems of Windows. Every patch on Windows affected our applications because the system had to be rebooted. Red Hat Enterprise Linux has improved the uptime of the applications.

For our company, Red Hat Enterprise Linux is a very secure operating system. It's much better than the Windows system. It's great for us. SELinux is a great tool to protect us from attackers. SELinux is the most important for us.

We have been Agile for two years, and Red Hat Enterprise Linux has been a part of it.

Its stability is most valuable. I'm a technical guy, and I love Linux. For me, it's the best platform.

Writing SELinux policies is sometimes very hard if you want to deploy a new application on it.

I started working in 2006, and my first job was administering the Red Hat Enterprise Linux system. 

It's very stable.

Its scalability is extremely good. You can scale it everywhere if you want. We have 600 to 700 Red Hat Enterprise Linux systems. 

The support from Red Hat is very good. The response time is rather low. We have premium support, and we sometimes get an answer to our questions in one hour. If you explain to the support guy your problem, you will get the current answer. Overall, I'd rate them a nine out of ten because you sometimes get someone who doesn't understand your question.

I don't know about the knowledge base of Red Hat Enterprise Linux, but I know the knowledge base of OpenShift is very good now. In the past, it was updated in one single version, whereas now, the change is there for each major and minor version. There is separate documentation, and that's much better than in the past.

Positive

It's getting better and better. In the past, versions 3 and 4 were very complex, but now, it's very easy to do it. We are now creating images and deploying it on our VMware farms, and it's much easier than making a PXE boot from our bare metal systems. 

We evaluated other solutions. We went for Red Hat Enterprise Linux because of better handling. It might also have been cheaper, but I'm not sure. My company decided to go with Red Hat.

As an operating system, I would rate Red Hat Enterprise Linux a ten out of ten.

I use the solution to develop OS for our internal use. I deliver it to our internal clients, so they can use it for whatever applications they may need to use it for.

The product is very stable. The knowledge base is excellent.

The solution should improve its documentation.

I have been using the solution for 16 years.

The solution scales well.

The support is good. I would rate support an eight or nine out of ten. The documentation should be improved to make it a ten.

Positive

The deployment is very easy for me because my organization has been doing it for a long time.

The product’s resiliency is pretty good. It responds fast to security updates compared to some other closed-source vendors. 

We moved from other priority operating systems to Red Hat Enterprise Linux because it saves us costs on the commodity hardware. Overall, I rate the solution an eight or nine out of ten.

Its use cases include general system management, setting up service with the web server, setting up a virtual, private wall with OpenVPN and FTP servers, etc. I have been working with all the aspects of the system in general.

The stability and the number of users that can access the servers are some of the valuable features. 

The stability of Red Hat Enterprise Linux is most valuable. I have machines running and working for hours, weeks, and months. The servers don't go down. In Windows, too many services hang, but in Red Hat Enterprise Linux, the servers continue working for months. I have had to reboot the machine only two times in years. The system keeps on working. So, stability is the best feature. 

Red Hat Enterprise Linux is very secure. There hasn't been any successful attack from hackers in years. It's one of the best features. The iptables command is helpful for setting your firewall policies. Only the machines that have the permissions can access the box.

We have had issues with the identification of new volumes when you add new disks or storage. You need the remove the machine, which can cause problems when you have high availability. If they can resolve the problem of detection of new volumes, it would be good for system administrators.

I've been using Red Hat Enterprise Linux since version 6.

It's very stable.

I don't have direct contact with their support, but I know that their support is good because I know people who work directly with their technical support.

I've worked with Ubuntu, Debian, SUSE, and other companies. In the past, Debian was the better operating system for servers and Red Hat Enterprise Linux was the better system for desktops, but nowadays, Red Hat Enterprise Linux, CentOS, and Oracle Linux are the better system for servers in my opinion, and Ubuntu is better for desktops.

This operating system is used by our clients. We don't have it in our organization. We use Windows. I'm not the one who decides about this. My director is the person who take decisions, but I prefer Linux. I like Red Hat Enterprise Linux in servers because there is support, stability, and more users that can access the service. However, in our organization, we use Microsoft Windows because they are partners. 

Most of our clients are institutions or public organizations. They have their own infrastructure for security reasons. Having a cloud environment has its own advantages and having your own infrastructure has its advantages. I prefer having my own infrastructure. When you have your own infrastructure, you have more control over all the processes and data of your organization, but I understand that having a cloud setup has advantages because you can manage and automate several systems or processes in the organization.

It's easy to install Red Hat Enterprise Linux. It's not difficult to install. You have the typical steps of the installation of any Linux-based operating system. Anyone can install this operating system. If you want to install servers such as an Apache server or a web application server, you need certain skills, but the installation of the operating system is easy.

I don't know about the pricing because I am not responsible for taking decisions about products used in the enterprise. Our clients use this product, and we use this product with the clients. In my home office, I use a free operating system. There is no support, but I can use it to practice. Our clients need support because it's used in the production environment. I don't know the price of the product, but I understand that with the support that Red Hat offers, compared to other operating systems, Red Hat Enterprise Linux is cheap.

It's easy to install and secure. You can customize it and manage various aspects. It's a good operating system for servers with security. It can run on machines without a powerful CPU or a lot of memory. It's stable.

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