Red Hat Enterprise Linux (RHEL) Reviews

A lot of our Red Hat operating systems run middle-tier applications. We are mostly a JBoss shop, so they are homegrown applications. They are Java-based. We have several types of applications. We have identity, security, Oracle database, etc.

Red Hat Enterprise Linux helps with standardization. A lot of middle-tier applications hosted in the data center or in the cloud are unified in one standard operating system, which is Red Hat Enterprise Linux. On the data center side, we only have Red Hat Enterprise Linux. We have one unified operating system.

For our containerization projects, we are looking into OpenShift. Our Ansible Automation Platform executioner uses container-based Red Hat Enterprise Linux. We use Podman. We have moved to the Red Hat Podman container. It is a lot easier. We can scale up easily and manage it. It reduces the security risk. We do not have to worry about patching. We can just image a new container that is up to date. That is great.

We had a situation where we had to create an image for Red Hat Enterprise Linux 9, and there were built-in playbooks for hardening the system. We were able to run that and create the image. It made the work much easier than it used to be in the past.

Red Hat Insights provides vulnerability alerts and targeted guidance. It has that capability. It has a lot of features built in that not only help with security but also with misconfigurations. If a system is misconfigured, it detects that. It gives you the solution for the problem it captured. It is a great tool, but we have been focusing on the security perspective. We have not been focusing on operating system configurations. I have not yet looked at the new version, but in my opinion, it would be better if Red Hat puts a lot of focus on Insights and take it to the next level where the company could use it for its OS compliance.

We have all types of different versions running in our environment except the obsolete ones. We are moving towards versions 8 and 9. We have had version 7, and it has been very stable until now. It is ending this year around June 30, so we are in the process of moving to version 8, and we have just released an image for version 9. So far, version 8 has also been very stable.

It is a Linux-based operating system. It integrates with our automation base. We have Red Hat Satellite and Red Hat Ansible. All the engineers who are a part of our infrastructure or operation on the Unix side are Red Hat Enterprise Linux certified, so it is a lot easier for us to manage and integrate with the tools that we have. It makes much more sense from the middleware perspective and management too.

The bootup time for Red Hat Enterprise Linux running on physical hardware in the data center can be improved. We have seen cloud-based Red Hat Enterprise Linux, and it is instantaneous. You wait for a few seconds, and the operating system is up and running. It is a lot faster, whereas it takes a very long time when running Red Hat Enterprise Linux on physical hardware.

We used Red Hat Insights, but we are more focused on compliance, patching of operating systems, and things like that. In the past, when we looked at Red Hat Insights, it was its own platform, and then it migrated to Satellite. Companies are struggling to be compliant from the security side. Everyone is focused on how to patch the systems, what the environment looks like, whether they are under 90-day CVE, how their environment is compliant, and where they can see it as a dashboard. I wish Red Hat Insights was focused on that. From the Red Hat perspective, I am not seeing any sessions. I do not see anyone talking about that, which is a huge deal for us. I would like Red Hat Insights to go to the next level where it is focused on patching and compliance.

I do not have any other areas of improvement. It has been stable for us. There is a lot we do in terms of automation and integration. I know Red Hat 8 now has Podman for containers. Cockpit has a UI, so that is good now. That helps with certain things.

We have been using Red Hat Enterprise Linux for close to 20 years.

We have not run into something that caused a huge problem to our environment. If something is happening, such as it is running an Oracle database and that system has kernel panic or something like that, it is usually the database or application software running on the operating system. It is not the operating system itself.

We have not run into any major infrastructure incident costing us because of the operating system. They have it integrated with all other products such as OpenShift, OpenStack, etc.

We have three data centers at different geographical locations. Two are in the state of Georgia and one is in Las Vegas. In all three data centers that we manage, the compute-based are all Red Hat-based. 

We have a Red Hat TAM, and that helps a lot in terms of the problems and things that we run into. He is the interface with Red Hat. He escalates our service tickets and things like that. That is a huge help from our perspective.

The support that we get directly from putting tickets in has always been great. Red Hat Enterprise Linux is probably the best and most stable product that Red Hat has especially in regards to getting support and getting things fixed. They are on top of that. It has been a great experience. I would rate them a ten out of ten.

Positive

We used to run Sun Solaris. We were a Sun Solaris shop in the beginning. This was 15 or 20 years ago. We moved because of the Intel-based hardware, licensing, and cost reduction. Moving away from Sun SPARC hardware to Red Hat was a lot of saving. It saved a lot for the company. We can now run Linux-based systems on Intel commodity hardware using Dell.

Its usage is growing. Our team is working with other business units within the enterprise to get them onboarded to the Red Hat-based operating system. We have multiple entities that are running CentOS and Ubuntu. We have to have a standard operating system, and that is Red Hat. Our portfolio is increasing. We are growing and migrating a lot of nonstandard ones to Red Hat.

We have an enterprise technology group that utilizes Oracle Linux. We have worked with OEM. Our team is managing that too.

We are using Red Hat Enterprise Linux on-prem. We also have a cloud environment, but other teams are using it on the cloud. The cloud provider is AWS. The database team also uses Red Hat Enterprise Linux in AWS.

We use Red Hat Satellite and Ansible for Red Hat Enterprise Linux deployment across all three data centers.

My first deployment experience was almost 30 years ago. I started with Red Hat Enterprise Linux 4 or something like that back in 1993 or 1994. There has been a tremendous change in the way you install it and utilize it now. It is night and day. It has come a long way.

We implement it on our own.

Our costs are reduced. We can allocate that OpEx and focus on some other project. We do not have to struggle and say that this is how much we are going to pay licensing just on the operating system cost. We now have a model that works for us.

We are a huge VMware shop. Our licensing cost works well with Red Hat. We license based on the data center. The way our license works is that we can run as many Red Hat VMs as we want and pay for a single license. On the VMware side, we gain a lot, and it makes much more sense.

We did not evaluate other operating systems and compared them with Red Hat Enterprise Linux. We just went from Solaris to Red Hat.

We are an agile environment. We practice agile methodology. Anything we manage and deploy has to go through a sprint phase. We do not have a fully containerized environment. In the future, once we adopt OpenShift, it is going to increase our productivity because of how we manage things through agile. It is going to help us a lot.

To a colleague who is looking at open-source, cloud-based operating systems for Linux instead of Red Hat Enterprise Linux, I would say that it all comes down to the company and how a company foresees security. Anything we support and manage has to have a support base. If something gets impacted from the security side, we know that we have Red Hat support, and it is reliable. We can get the patch we want. If you install an application that needs a bug fix, you can reach out to Red Hat and open a ticket. If you want to have a stable environment, then I would highly recommend getting the support and running Red Hat.

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

We have a database that we maintain for root passwords, and sometimes I need to break the root password to reset it. We work a lot on logical volumes where I need to grow and shrink volumes on the fly. I did not have to shrink the logical volumes much, but I worked a lot on growing logical volumes on the fly to make them available for the database team. I have done network-related things. I configured network multipathing or IP multipathing where we can parallelly route the traffic to multiple ethernets.

I work a lot on user-related issues as well. We are also using Ansible a lot for automation. I am writing some playbooks, so there are a lot of use cases.

Red Hat Enterprise Linux helps us a lot. We host a lot of our applications on the Red Hat platform. We are using Red Hat Enterprise Linux for both on-prem and VM platforms. Most of them are VMs, but we do have some old legacy systems where we have Linux running on some Dell architecture. Our goal is to get rid of them this year and implement everything on virtualization because virtualization is growing a lot.

Red Hat Enterprise Linux has enabled us to centralize development. We are using it in the production and lower environments. We are using a common platform for our deployments. We have a centralized environment.

In terms of portability of applications and containers built on Red Hat Enterprise Linux for keeping our organization agile, it is flexible. Agile methodologies are very popular nowadays, and they help with coordination between dev and production teams. It is fulfilling the gaps between these teams. It is helpful.

I see so many features in Red Hat Enterprise Linux that I do not see in other Linux operating systems, such as Ubuntu. That is why Red Hat is very popular. All my experience is mostly on the Red Hat side. In terms of features, I like breaking root passwords, and I like the XFS file system over ext4.

I have not used it on the cloud side. I have not heard much about how Red Hat is doing on the cloud side. In the market, AWS and Azure are very popular, and they have captured most of the market. If Red Hat can improve on the cloud side, they can retain their customer base. Their customers do not need to go out for other cloud resources, and they can use the Red Hat cloud.

We are using it on-prem and in the virtual environment on VMware. We are using a cloud, but it is not a Red Hat cloud. We are using AWS in our organization. We have some EC2 instances deployed with Red Hat Enterprise Linux images, but I cannot say it is a Red Hat cloud. It is an AWS cloud, and we have instances. We are depending on a third-party cloud. If Red Hat provides that kind of service to our company, we can retain Red Hat. We do not need to go for a public cloud.

I have been using Red Hat Enterprise Linux for almost 12 years. I started with Red Hat Enterprise Linux 5.

It is a stable platform, but our company still wants to stick to the older version. They do not want to change the application base. They do not want to take risks. Unfortunately, Red Hat is not able to help to provide the patches for older versions. They suggest upgrading, but management is not doing that, so the Red Hat Enterprise Linux side is good, but our management side is bad.

Its scalability is good. We plan to use it more. We are growing. As our infrastructure grows, we are buying more licenses.

Their customer service is excellent. I like it. I am in touch with Ed who is one of the support engineers with Red Hat. He is helping me. 

I am also in touch with a few other people at Red Hat. If I run into any issues, I can simply email them, and I get a quick response from them. Based on the support I am receiving, I would rate them a ten out of ten.

Positive

We did not use any similar solution previously.

We are using it on-prem and in the virtual environment on VMware. Our cloud provider is AWS.

We are using the CI/CD model for Red Hat Enterprise Linux. We are using blue/green deployments as well for our containerized applications, and we have some canary deployments.

My initial deployment experience with Red Hat Enterprise Linux was not great. It was not as easy as the current version. It was difficult during those days. We had to load the GUI and then change to CLI. It is better now. Red Hat has made some improvements in the newer versions. The current version 9 looks better than any other previous version.

I did not use any integrator or consultant. I downloaded an ISO image from Red Hat. I downloaded and installed it myself, and it worked very well. I did not run into any issues with the installation process.

Over the last few years, we have been within budget. We do not have any constraints about Red Hat. We are a big organization. We use a lot of products from different vendors. We are working on cost optimization for some of the vendors but not Red Hat, so Red Hat is still good. We are still happy with it.

The biggest return on investment is the customer base. We are in the telecom industry. We try to get as many customers as we can. Red Hat is not the only product that we are using, but it is a major product that we are using in our company.

We are good as of now. We do not have any concerns about licensing. Its price is still good for us.

We are not using Red Hat Enterprise Linux for containerization projects. We are using Kubernetes and Dockers for that.

When it comes to patching, our goal for 2024 is to make all the systems compliant. Especially at the infrastructure and application levels, I am actively working on the compliance tasks, and our goal is to fix all vulnerabilities. I am working with someone at Red Hat on some issues because I am not able to find the exact patch for certain vulnerabilities.

For now, we are happy with Red Hat Enterprise Linux. We are happy with what we are getting.

Overall, I would rate Red Hat Enterprise Linux an eight out of ten. The reason for reducing two points is that I have not explored other operating systems very well.

I use the solution in the company to build a lot of our software environments, so we keep different baselines on it. Right now, I'm working on setting up and installing Ansible manually, so I haven't used Red Hat Ansible Automation Platform yet, a reason why I have been still using my Red Hat Enterprise Linux (RHEL) server.

In terms of features, I found it great when I talked with Linux subject matter experts about Ansible. They further mentioned that it was native to Red Hat, which is why it wasn't going to bring over more packages or modules. The packages or modules in the tool are already there but are just not enabled because they weren't being used before I asked about them. It is super easy to enable the tool's packages or modules when I want to start messing with it.

Red Hat Enterprise Linux (RHEL) has helped me centralize development because it has a standard, which is why my company can't really have the option to mess with its different technologies. Our company's customers don't want to use Ubuntu or any other such operating systems, which is why my company has to use Red Hat Enterprise Linux (RHEL). I guess the tool is easily centralized because that is its standard, and that is the only option one has unless someone wants Windows, but again, developers don't want Windows, and so there are no other options.

Our organization has a team to take care of the containerization part. I am mostly on the infrastructure side, but my company has started to ask me for Podman Desktop and all these different container platforms, and I haven't used any of them yet.

If I dissect the built-in security features of Red Hat Enterprise Linux (RHEL) for risk reduction, business continuity, and compliance, I would say that we use VMware for risk reduction so that we have a high availability. On the top of my head, I think the Linux team probably knows more about reducing risks. Our security team has all these STIGs they want us to apply, so I don't know how much manipulation they actually have to do.

If I dissect the built-in security features of Red Hat Enterprise Linux (RHEL) for risk reduction, business continuity, and compliance, I would say that we use VMware for risk reduction so that we have a high availability. On the top of my head, I think the Linux team probably knows more about reducing risks. Our security team has all these STIGs they want us to apply, so I don't know how much manipulation they actually have to do. For business continuity, my company uses VMware, considering the ease of making snapshots of our environments, but I believe we could probably do the same with different operating systems. In our company, we just take lots of snapshots, and then if we have another VMware instance, we could just build it right back. The only compliance I know about was associated with our company's customer and their STIG requirements, but I don't know how Red Hat Enterprise Linux (RHEL) helps with it, especially considering that in our company, we have to manipulate it and how we want to do it.

In terms of the portability of applications and containers built on Red Hat Enterprise Linux (RHEL) to keep our organization agile, I would say that we have an applications team that would do it in our company. I just make sure that our company's VMs have OS and network connectivity since there is a different team that takes care of the applications.

Right now, since my company is in an air-gapped on-prem network, it is really tough to go through all the RPMs that we have to have based on different STIGs. Whenever in our company, we have to install the tool, we see that something or the other is missing, and so of the hundreds of things mentioned in the list, we have to find whether we need a particular RPM or if we need to take this one out, and that is always a trouble for the team managing Linux in our company.

I have been using Red Hat Enterprise Linux (RHEL) for more than five years.

When I spoke to one of the speakers the other day, who was a software development manager, I was told how much one could trust Red Hat Enterprise Linux (RHEL). I believe that Red Hat Enterprise Linux (RHEL) is considered a standard for a reason.

I believe that if you have enough license to support the product in your environment, then you can scale the product depending on how big your license is, and it is a super easy process where one can roll out a whole bunch of VMs and VMware.

As my signature block comes with Lockheed Martin, I think the tool's support team has been pretty attentive. If I go to a wide-scale service and once Red Hat Enterprise Linux (RHEL) sees what kind of a customer I am, I get to go to their specialized sectors, and the support has been pretty fast. I have had no issues with the product's support team. I don't use the product's support services very often. I have mainly dealt with Red Hat's support team for Ansible. I rate the technical support a seven out of ten. When I was asking the tool's support team questions when I was off the internet, I just kind of felt weird about it. For any service I ask for from the support team, I have to manipulate it depending on what we need for our company.

Neutral

I have not previously used any other product, and I have worked for the government for the past twelve years using Red Hat Enterprise Linux (RHEL).

The deployment of the product has been super easy, but when we do it through VMware, I just make a VM, and then load an ISO image, after which the deployment is done. The tool's deployment is super easy, and I am pretty much a novice when it comes to Linux.

The solution is deployed on an on-premises model.

My company did not seek the help of a third party to depot the product. The deployment was carried out by our company's employees, who have been around for decades.

The government buys the product for our company and provides us with the license for the solution.

For a colleague who is looking at open-source cloud-based operating systems for Linux, I would say that Red Hat Enterprise Linux (RHEL) is a cool product for small businesses outside of the government. I work for the government, where Red Hat Enterprise Linux (RHEL) is the standard, so if my colleagues are in the government, I would tell them they have no other options.

I am not sure about the product's deployment model since it is kind of ad hoc in nature. If a developer needs another VM, our company just provisions it through VMware, so we don't have a large-scale deployment model across different availability zones. We have our program, after which we wrap it all up and then ship it out to the customer.

As I have not compared Red Hat Enterprise Linux (RHEL) to any other operating systems in the market, I rate the tool a nine out of ten.

We use Red Hat Enterprise Linux primarily for our entire group because most of our applications are based on Linux.

Red Hat Enterprise Linux has robust built-in security features.

It has an extensive knowledge base.

We used to patch our systems manually, and now we use Red Hat Satellite to manage the patching of our systems.

Red Hat Enterprise Linux provides a good way to manage our OS.

It has enhanced both our uptime and security. The system's stability has eliminated any noticeable security issues.

Red Hat Enterprise Linux has enabled us to achieve security standards certification, which has allowed us to maintain business operations without interruption.

Red Hat Enterprise Linux is a stable and supported platform with valuable built-in security features that help reduce risk and maintain compliance.

The cost of Red Hat Enterprise Linux is a bit high. 

Red Hat Enterprise Linux's support could be improved by offering human support in addition to their documentation. While their documentation is helpful, it can be frustrating to be referred to it instead of receiving direct assistance from a support representative.

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

Red Hat Enterprise Linux is stable overall.

Red Hat Enterprise Linux is scalable.

Red Hat's support is generally good, but their response time and overall competence could be improved. Occasionally, we are referred to their documents when requesting assistance, which can be frustrating.

Positive

Red Hat Enterprise Linux has a yearly subscription cost for the licensing that includes maintenance and support.

We evaluated Microsoft Windows Server, Ubuntu Server, and Red Hat Enterprise Linux before ultimately choosing Red Hat Enterprise Linux.

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

I recommend Red Hat Enterprise Linux for its support and stability.

Most of our tech applications are based on Red Hat Enterprise Linux.

We chose Red Hat Enterprise Linux for most of our workloads and applications because it is an enterprise-grade operating system with regular security patches, reliable support, and a guarantee against hacking. Using a different OS would leave us vulnerable to security risks and complicate upgrades.

Currently, 70 percent of our Red Hat Enterprise Linux environment is deployed on-premises, while the remaining 30 percent resides in the cloud.

We utilize Ansible to automate the deployment of numerous Red Hat Enterprise Linux modules. This centralized approach, managed by a single Ansible engine, streamlines our development process.

Red Hat Enterprise Linux performs well for our business critical applications.

Red Hat Enterprise Linux's built-in security features satisfy our security requirements.

Red Hat mitigates risk by rapidly releasing patches for identified vulnerabilities, which is crucial for mission-critical applications.

It offers stability that enhances business continuity, simplifying upgrades, even for minor releases. Its compatibility with OpenSCAP, which provides profiles for various compliance benchmarks, streamlines compliance testing.

Red Hat Enterprise Linux provides regular security patches and proper support, allowing me to focus more on application management than worrying about the operating system.

It helped us avoid emergencies caused by security issues. The CVE reporting and knowledge base are valuable resources.

Red Hat Insights provides the tools for proactive environment management by identifying potential vulnerabilities, such as CVEs before they become a problem. This allows for advanced knowledge of system vulnerabilities and provides specific remediation guidance, which is more efficient than relying on regular scans.

Red Hat Enterprise Linux has helped reduce our total cost of ownership.

Red Hat Enterprise Linux is an enterprise-grade solution where we receive regular security patches and proper support.

Red Hat Enterprise Linux was not used for containerization due to its mutable nature, unlike CoreOS, a lightweight and immutable Red Hat Enterprise Linux variant designed explicitly for containerization and optimized for running authorization.

I am testing AI workloads, and I'm not sure if Red Hat Enterprise Linux is fully equipped. It might not accommodate AI workloads as effectively as needed.

Some Red Hat applications, such as Ansible for automation, are considerably more expensive than the average open-source solution.

I have been using Red Hat Enterprise Linux for 16 years.

Red Hat Enterprise Linux is stable, and I have not encountered issues compared to other applications.

Red Hat Enterprise Linux is scalable.

Red Hat's stability has meant I haven't needed their support for years, but when I did contact them previously, their response was quite fast. While their support for OpenShift is acceptable, I do have some concerns about it.

Positive

A stable OS allows me to focus more on applications, lowering the cost of managing the infrastructure.

Red Hat is stable, and we always opt for the lower-tier subscription, which is affordable. It doesn't have unexpected issues that require a premium subscription.

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

It is important to assess the risk and use case before choosing a third-party Linux OS. For mission-critical applications, Red Hat Enterprise Linux provides insights and rich features like the patching cycle.

We first used it for application installation to run applications on Windows. We had it running on Windows. We then upgraded it. It was still on the IBM platform, but it was still x86. We have now updated it, and it is now running on IBM Linux Z.

We use it for Internet banking, core banking applications, and other peripheral applications.

It has helped with consolidation. When we first started to do clusters, we were using Oracle cluster and Red Hat cluster. The Red Hat cluster was more stable than the Oracle cluster, so we had to uninstall the Oracle cluster and just use the Red Hat feature to have floating IP addresses between two cluster nodes. Having it in a cluster was the single most useful application of Red Hat in the environment.

We use Red Hat Insights, Ansible, and Satellite. Red Hat Insights is helping us big time. A year ago, I was looking at bolstering my team to about five or so administrators. With Red Hat Insights and other tools, I am satisfied with just two administrators. They are there just to manage the system and not necessarily go down into the trenches.

It seems that Red Hat Insights provides vulnerability alerts and targeted guidance, but my team would know that better. I manage a team that does that.

Its stability is most valuable. Its administrative aspect is also good. It is relatively easy to administer. I am familiar with AIX. AIX is super easy. I did not have to struggle much to adapt to Red Hat.

They can make the extended file system dynamic. Currently, we have to bring down the server to add an Hdisk. We cannot extend the database on the fly. We have to have downtime. We want to ensure that we make the blackout periods as minimal as possible. Currently, there is a gap in the file system management. I want to be able to expand the file system in a simpler way and have the application or the database use that expansion without any downtime.

I have been using Red Hat Enterprise Linux since 2004. It has been 20 years.

There is no problem with stability. It is stable. We have a couple of Red Hat Enterprise Linux 4 still running. We also have Red Hat Enterprise Linux 6 systems. The hardware is functional, but the application was retired. We cannot get an update for it. It has been running since 2008.

Its scalability is fine. There is no problem with scalability. We can do it in real-time. Now with containers and other things, we can scale on the fly without much downtime. We can build a small system and scale it. We can start at a much lower level than several others.

It has improved tremendously. I remember when it used to be centralized. I have been to North Carolina to get training, but now they can come to us for the training. The whole support architecture has improved. We can reserve hours for calls when the need arises. If we do not use it, it is reallocated the next month to some other project. They are doing well. I am impressed.

Positive

We were using and still are using AIX, but most of the applications have been imported, so we are between AIX and Red Hat. We are also using Windows, but Red Hat has stood out. It is not yet there with AIX, but it is getting there.

We were using Ubuntu and a few other flavors, but they were not organized. They were still too open. The support and the training for Red Hat Enterprise Linux was spot on. It was exemplary. We could find support easily.

We have them in clusters, and we also have standalone ones. We have DR where we synchronize with DR. We synchronize at the file system level with DR, which eliminates some of the application limitations.

We are using it on-prem, but we have applications to be upgraded in another 18 months, which would be a hybrid cloud.

Its installation the first time was overwhelming. Once you get used to it, the team settles down, and you have knowledgeable people, it is a breeze.

We have an integrator, a reseller, and a consultant. Somebody would come in and help us connect the dots. I guess that is their reseller, and then the integrator helps us properly connect the dots.

Pedro is our accounts manager. He probably comes from Puerto Rico, and then there is Lincoln Walters from Jamaica. Together, they help us identify the resources we need for the things that we want to do.

The biggest ROI is in terms of the reduction of human resources required to manage and maintain it. The administrative duties have been vastly reduced. You can even have resources from Red Hat. They have something where you can block certain hours a month and you can just use them as needed. If you do not use them entirely, you can reallocate them. That means you can reallocate unused resources. There are savings on investment.

We are still learning about it, but our TCO has reduced because we do not have to have as much manpower, hardware, and processes to manage and operate.

Licensing is the most attractive part of it. With Red Hat Insights and Ansible, we now know that it was done with the intention of simplifying the licensing so that you get the support for what you have and not necessarily what you want to have.

Red Hat Enterprise Linux has not helped us to centralize development. We have not capitalized on that as yet. I am here at the Red Hat Summit to learn about Kubernetes and containers. It is all new to me, and at this point, I do not know from where to start. I am getting exposed to so many things, but I still need to understand from where to start. I need to know the foundations. In about 18 months, we will be going to containers. We have people developing Dockers, Kubernetes, and other things, but we need to find a way to integrate them. We will have containers running on OpenShift, but we need to know how to secure, store, and manage those containers.

I have participated in a few presentations, and I see that there are prescribed ways to ensure that you maintain compliance by upgrading. In one of the presentations, one of the presenters said to not expand or scale too quickly because some of the applications get left behind. That is something that I am taking away.

The portability of applications and containers built on Red Hat Enterprise Linux will be good for keeping our organization agile. It is flexible. They say, "Build once and run anywhere." That is the buzzword for me.

To a colleague who is looking at open-source, cloud-based operating systems for Linux instead of Red Hat Enterprise Linux, I would say that Linux is for beginners, whereas Red Hat Enterprise Linux comes with the bells and whistles and the stability for business. It is an enterprise-grade software.

Overall, I would rate Red Hat Enterprise Linux a nine out of ten. There is innovation and adaptability. Ten years ago, it was unheard of. It has grown, and it has been growing tremendously.

We are a Linux shop, so a lot of our engineers are familiar with Linux. We try to push Red Hat Enterprise Linux instead of Windows. The reason for it in the beginning was licensing. Some of it was because of the way the contract was set up. It was cheaper, but we do use it now just for the ease of it. I do not know if it is because of Ansible, which we use for a lot of our day-to-day operations, that we tend to lean more toward Red Hat.

Red Hat Enterprise Linux has affected our system's uptime or security. I know Microsoft publishes zero-day vulnerabilities for Windows as fast as Red Hat, but we noticed that in terms of problems or alerts that we get for attacks or viruses, there is not anything on the Red Hat side. That is why we feel that it is more secure. It might be just the nature of Red Hat where all services and ports are off. It is not like Windows where everything is on, and you have to turn it on. I was having a conversation with one of the gentlemen who is also attending the Red Hat conference, and I got to know that there are built-in NIST features with Red Hat that we could turn on, so we do not have to try to figure out how to harden our system.

The testing of the updates or the packages of the kernel is valuable because I used to be a part of the Fedora project. I know it is all vetted out before it gets to production, but a majority of it is the support and the relationships I have with the Red Hat employees assigned to our account.

As they move over to newer versions, certain things change, which is expected as the technology matures or new things come out, but what really surprises me are the features that are there in the cloud, such as Red Hat Insights. They are not there on-prem. There are a lot of things on the cloud portal that I did not notice before, and I was surprised because we were unaware of them. Red Hat is doing a lot of investment in that sense.

The knowledge base offered by Red Hat Enterprise Linux is good. It is easy to parse through all of the knowledge base. I do not know if Windows does it because I have not looked at it, but in Red Hat's knowledge base, there are a lot of things. They fast-track a lot of things in their knowledge base, even when they are not yet official. Especially with the tie-in with Bugzilla, even though it is not a true KB, we can see and follow if other people in the world are hitting a certain problem or something similar to what we are experiencing. I like that.

It would be great to have an overview of how various Red Hat products work together. They can show how to tie all those pieces together and how to have the products that we work together for our day-to-day processes.

I started with the company around 2012, and they have been using it even before then. At that time, it was Red Hat Enterprise Linux 5, and now, we are up to Red Hat Enterprise Linux 9.

In 10 or 11 years of using Red Hat solutions, I have opened only one or two support tickets. It probably was something during a patch and during Satellite 5 to Satellite 6 migration. I would rate them a 10 out of 10.

In Linux, there are so many different flavors, but I am partial to Red Hat because I have been a part of the Fedora project. At our place, we have only two operating systems: Microsoft Windows and Red Hat Enterprise Linux. I know CentOS, but that is usually because the appliance from the vendor was set up using that. That is why we had a few instances of CentOS in the past, but nowadays, I do not see any other flavors of Linux.

For the majority of our use cases for Red Hat, we have on-prem deployments. There are some things that they are trying to spin up on AWS. I do not know if they are cloud-native apps or not, but I know our developers are now moving on to it.

I have been involved in the initial setup, upgrades, and migration of Red Hat Enterprise Linux. I did not have any problems while going from major OS versions. I always push new upgrades or homogeneous migrations, such as from version 6 to version 7 to version 8. There is probably an option to upgrade in place. Overall, with Red Hat OS, I have not seen many problems. A long time ago, when they went from Python 2 to Python 3, there were certain things we had to change in the script.

I know that Red Hat is moving to Wayland from X11, but I do not see any problems there. From Satellite 5 to 6, it was a bit hard in the beginning, but now, it is pretty self-explanatory. Overall, everything about which we had questions was very well documented.

In terms of our upgrade and/or migration plans to stay current, first, we look at the EOL and the roadmap of Red Hat because of security. We used to offer every single version before the said EOL happened, but now, we just do an n-minus-one. We try to maintain the newest and one level below version. SAP users are the biggest Red Hat Enterprise Linux users in our environment. They have a particular PAM and upgrade path that they have to do with Red Hat. We also wait to be certified to certain versions, but our main strategy is the newest and one major version down. We try to get everybody off the other versions.

Our provisioning is all done using VMware products. We have a vRealize automation, now called the Aria automation, to spin it up. Patching is done through Satellite. I do not do it, but when I watch them doing it, it seems it is just using remote SSH commands against the list of non-prod and prod servers. It is something simple. We do not seem to be doing anything complicated. I am wondering if there is a better way to do versioning control or patching and whatnot, but currently, it is very simple.

I am satisfied with the management experience not only in terms of patching but also the day zero to day one or day two stuff. We are interested in utilizing Ansible to eliminate human error and whatnot. During provisioning, we have Pearl scripts that we have to manually trigger. I know we can use Ansible for that, but it comes down to the cost of entry which is still very high. 

A lot of people are moving into the core count for licensing. We still have a few with one-to-one standard server licensing, but we are utilizing the virtualization host licensing. We license it based on the host, not based on VMs, which is cool. I was very happy that there was certain licensing with SAP to have access to SAP repos. Its cost was the same as the regular one, so I was happy about that.

The only pricing that bugs me right now is the Ansible pricing. We wanted to take a look at Ansible, but the biggest thing a year back with Ansible was that the management did not want to spend half a million on Ansible Tower. They wanted to see first if we would use it and not waste money. I do not know if things have changed now, but Ansible is probably still expensive. That is one of the routes that we want to go to. We will see if we can utilize Ansible Tower, so pricing-wise, that is the only thing that pops up. It is too expensive. The cost of entry seems quite high.

Overall, I do not see any issues with what we have spent on Red Hat. We also have learning subscriptions that we pay to Red Hat for the training, and I do not feel we have wasted any money.

Red Hat Enterprise Linux has built-in features, but we do not use them. It is one of the things about which I need to talk to our account manager. There are so many different ways to skin a cat. My department has so much money, so they bought everything, but a lot of the security features, such as SELinux, are disabled for us. We handle the firewall rules, access lists, and other things at another location rather than on the actual VM itself. It does not hurt to do it at multiple places, but operations-wise, it would be a nightmare, so we try not to do it. I know there are a lot of cool new things built in Red Hat, and that is something we should circle back and take a look at.

I have seen Red Hat Insights. I clicked on it one time when our account manager was showing us something. They have so many features in the cloud that we do not know we can use. Maybe it is wrong to assume, but the reason I do not look at Red Hat Insights is that a part of our patching is already included. We are not that strict about what we patch in terms of the versions. It is useful, but Red Hat emails us anyway. They tell about the severity of an issue. We do not look at Red Hat Insights. We see those emails and we see CVEs. If a package is installed and applicable to our VMs, we just use Satellite and patch that particular vulnerability. 

I have also tried the web console once. It looked interesting, but we do not have much use for it because a lot of our customers or application owners are server admins. About 99% of our Red Hat installs are all minimal installs. We do not have a GUI. There is just a terminal screen. Even though they could console in and do whatnot, it is all done via SSH.

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

Our memory-intensive applications run on Red Hat Enterprise Linux.

We opted for Red Hat Enterprise Linux for our workloads due to its stability and the comprehensive support provided.

Red Hat Enterprise Linux has enabled us to centralize our development to some degree.

We use it in containerization projects for workloads that need to run in private clouds, as it simplifies the process of shipping them as containers. The advantage of this approach is standardization, while the disadvantage is the necessity of shipping the container itself. Deploying containers on a platform like Kubernetes running on Red Hat Enterprise Linux may require some extra steps for scalability, but it is not a significant obstacle.

I appreciate that Red Hat Enterprise Linux, as a foundation for hybrid cloud deployments, is a commercial solution with reliable support.

Red Hat Enterprise Linux has performed well for our business critical applications.

We extensively use Red Hat Enterprise Linux's built-in security features because they are excellent.

Red Hat Insights has significantly helped us reduce risk in our environment by allowing us to identify which CVEs are impacting our systems.

Red Hat Enterprise Linux contributes to business continuity and compliance efforts by simplifying OS migration. Its generational upgrade path allows for easy transitions between versions, streamlining the process and reducing potential disruptions.

The time saved during audits and the ability to map CVEs using Red Hat Insight are valuable security benefits.

It helps avoid emergencies stemming from security issues, non-compliant settings, or unpatched systems.

Red Hat Insights provides the tools for proactive environment management. For example, it simplifies patch verification by confirming the desired automatic patching functioned correctly in one fleet, suggesting its likely success in the next. This clear visibility makes it easy to monitor ongoing operations.

Red Hat's portfolio helps lower the total cost of ownership for our enterprise landscape by providing reliable documentation that simplifies troubleshooting and reduces the need to resolve issues from scratch. 

Red Hat Insights provides good visibility and proactive management of our environment.

The primary issues are related to integration. Red Hat Insights utilizes several APIs that lack proper communication, resulting in inconsistent results.

I have been using Red Hat Enterprise Linux for about four years.

Red Hat Enterprise Linux itself doesn't have issues. It performs well for our business-critical applications.

Red Hat Enterprise Linux scales quite well, allowing us to adapt as needs change.

While the support is generally good, prompt attention often requires escalating issues or marking them as high importance.

Positive

Red Hat Enterprise Linux saves time with good documentation and other benefits.

The licensing is a bit odd because we need to procure the licenses from a third party. We prefer a pay-as-you-go model with monthly increments instead of buying licenses in bulk that expire in a year.

I would rate Red Hat Enterprise Linux an eight out of ten. While it has occasional bugs and software flakiness, updates are regularly released to address these issues.

To ensure your operations are compatible across different operating systems, prioritize OS agnosticism. Unless modifying the OS is a core function, consider a commercial solution like Red Hat. Although cost-effective, Red Hat may not be suitable for all companies.
