Red Hat Enterprise Linux (RHEL) Reviews

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 using Red Hat Enterprise Linux for running various things. We have a lot of virtual machines. The applications that are running on it are a bunch of shell scripts for processing orders, marketing campaigns, generating reports, or running some Java applications.

We have the customization capability. We can easily customize it, and we can also automate and deploy it. I have a command line interface. I am a command line junkie, and I am able to use that, config files, and Ansible to be able to easily figure out what I need to do to automate things. It feels like I know what it is doing and how to make it do what I want. I do not have to weave some magical arcane hack the way I have to do in Windows.

Red Hat Enterprise Linux has enabled us to centralize development in a lot of ways. We have it hooked in through our GitHub. We are trying to combine where we are storing things and then have a standard way of how we are deploying things and have some standard configurations. With every single server, we do not have to worry about how to set this up because we are doing the same thing the same way. We can just do it across the board, and then we only have to worry about the interesting parts.

Red Hat Enterprise Linux's built-in security features are great for risk reduction, business continuity, and maintaining compliance. There are published CVEs, and there is SELinux, which I do not use and I always turn it off. Firewalls and tooling around that make it easy to use. The automation on top of that makes it easy to configure. With a push of a button, it is done.

We do not have to worry too much about portability. We are coming from Oracle Linux. We were primarily an Oracle Linux shop, and because that is based on it, it just works. We have not had any issues.

The fact that it is Linux is valuable. Why I like it in general is that I know what it is doing. I can figure out what it is doing, and I can make it do what I want. I am not delving into arcane registry things.

I am still trying to figure out the features it has. There is so much that it can do. What it does really well is that it allows you to do things.

It was probably 2008 when I first started using it. The company was using Red Hat Enterprise Linux, and I was with the internal help desk supporting the Linux side.

Its stability is great. It is stable and rock-solid.

Its scalability is also great. It does not matter if the host is beefy or not. It is just going to run on it, and it is going to handle the work. Whether you have a couple of cores or 64 cores, it is just going to do it.

Their support is good. There is good responsiveness. They quickly get me to the person who knows the answer, but I have not used them much.

Positive

We were using Oracle Linux. We are switching because of some of the things. Oracle licensing has been a point of frustration. Their support is comparably difficult to work with, and the support documentation is a mess.

Red Hat is so much easier to navigate. It has been overall a much more pleasant experience to work with Red Hat.

We are using it on-prem, and then our cloud is a Kubernetes cluster on AWS, so it is basically on-prem.

Our deployment model is a manual kickstart with Ansible for configuration. My experience with deployment is good. I kickstart it and then hit it with Ansible, and it is done. It is very easy.

I did the deployment on my own.

We have not yet seen an ROI. It has not been in for long enough. There are no savings in terms of manhours because the actual day-to-day usage remains the same with Oracle Linux or Red Hat Enterprise Linux. However, getting some of the metrics with Red Hat Insights is going to be helpful as we get into a better patching cycle. I am anticipating an easier life.

We are expecting an overall decline in the costs because of the differences between the Red Hat licensing and Oracle licensing. We are expecting a net decrease in overall cost. For using it, other than the license, there is no cost.

The setup cost is non-existent. With licensing, there was a little snafu because I misread something. There was a slight learning curve because we use virtual data center licensing. We had to understand how it all maps. We had to understand how that mapping works when the hypervisors are Red Hat or VMware. There is a slight learning curve, but it worked out. It ends up being easy.

I did not evaluate other options mainly because I have had experience with it before. From my prior experience, I already knew what I wanted.

We are trying to use Red Hat Insights. I need to finish updating the playbooks to hook our host. We are in the midst of transitioning from Oracle Linux to Red Hat Enterprise Linux. I have not fully hooked everything in, but we will be using Red Hat Insights.

We just started using Red Hat Enterprise Linux for containerization projects. We have not yet seen any impact of Red Hat Enterprise Linux on containerization projects.

If a colleague is looking at open-source, cloud-based operating systems for Linux instead of Red Hat Enterprise Linux, a lot of it would depend on their use case, what they are going to need for it, and whether they have an enterprise environment. There is a cost associated with it which can be a downside. I am an open-source lover. I do not like paying for stuff, but I get it. They need to look at the cost, and if the cost is prohibitive, they need to look at something that is compatible and as similar as possible.

Overall, I would rate Red Hat Enterprise Linux a nine out of ten. I generally do not give out a ten. There needs to be something spectacular for a ten, so that is my personal bias against the top of the scale.

One of the valuable features is that it's convenient. 

The rest of its features are really nice.

Red Hat enables us to achieve security standards certification. We have been certified for the PPI certification last year. 

Red Hat has been good when it comes to building with confidence and ensuring availability across our infrastructure. We are really confident about the security process.

It is implemented across multiple physical and virtual infrastructures. We have applied it on most production servers. They are integrated quite well. 

We use the Red Hat system roles feature. We have been using this for automation purposes and to find some tests. 

The response could be better for urgent issues. If there's an issue with live services, they need to be faster. 

It would be nice to have antivirus services.

There should be more upgrades to the security features. 

I've used the solution for a long time. My organization has used it for more than three years. 

The stability is good. I'd rate it eight out of ten. 

The scalability is decent. I'd rate the solution eight out of ten. Different teams and departments, including application and development teams. 

We do not have plans to increase usage in the future.

I'm very happy with the technical support.

Positive

We have got some other open systems like CentOS. We just have most of our production services to ReadyX from CentOS and Oracle. Red Hat is more secure. The support is very nice as well.

I joined the organization after deployment and wasn't involved in the implementation. 

I'm not sure if the solution requires any maintenance. 

I'm not really involved in the pricing or the licensing. However, it may be expensive. We have different licenses. 

We evaluated different options.

I'm a customer and end-user.

I'd rate the solution eight out of ten. 

We have over a thousand VMs or physical machines running on Red Hat Enterprise Linux. We have various applications, and we also run the OpenShift Container Platform on-prem, so we have a lot of containers. They are migrating a lot of apps from the mainframe over to Spring Boot type of app. It fits well in the container.

Red Hat Enterprise Linux gave us stability. There is somebody to call when we have issues.

Red Hat Enterprise Linux has affected our system's uptime or security.

Red Hat Enterprise Linux has not yet enabled us to achieve security standards certification because we do not go after any of those. There are some products that we will have to do once we get there, but so far, we have not had to certify anything.

Red Hat Insights gives a lot of insights into known issues that we do not think about unless we call support. It tells us to proactively fix something.

I have used Image Builder and System Roles mainly for Red Hat Enterprise Linux for Edge. It builds out the OS tree build for us, which is very helpful. I do not like to do that myself.

I use the Red Hat console every now and then, but I do not use it heavily. I am old school.

The security updates and the support that comes along with it for applications are valuable.

Red Hat Insights was a nice feature to discover. I did not know about Ansible until probably eight years ago. I learned that language, and that was a void or something that was missing for over 25 years.

I like the SCAP Workbench interface that I can use to build some security around. I use Ansible to go out and do configuration management checks as well. Overall, I feel it is very easy to get the data I need.

We finally started doing Red Hat Enterprise Linux for Edge. That one definitely is an improvement. One piece that is missing is that we are required to use moby-engine, but currently, Red Hat Enterprise Linux for Edge forces Podman, so we have to work around it.

I have been using Red Hat Enterprise Linux for a decade in my current organization, but overall, I have been using Red Hat for over 25 years.

Early on, support was closer to a six, but now, it is a nine out of ten.

Positive

I have used them all back from the early nineties. I have used CentOS and others. The reasons for companies switching from those to Red Hat Enterprise Linux are that most of it is open source, and they get more product features. There is a market. If other companies are doing it, they tend to switch over. Containerization is a major reason as well.

I was involved in the OpenShift deployments. We are also directly involved in every version of Red Hat Enterprise Linux. We are involved in the proof of concept. Its deployment is straightforward.

We used Red Hat with the OpenShift deployments to make sure we were doing it right, and then a lot of other things, such as Red Hat Enterprise Linux 8 or Red Hat Enterprise Linux 9, we just did ourselves.

In terms of our upgrade and/or migration plans to stay current, we are upgrading everything to Red Hat Enterprise Linux 8, and we are going to Red Hat Enterprise Linux 9 already. We are making that a product feature. We are using Red Hat Enterprise Linux for Edge for our remote deployments.

In terms of provisioning and patching, we deploy the base image, and then we use Ansible for the configuration behind it. For Red Hat Enterprise Linux for Edge, we use the OS builders to build out that same image. I use Kickstart to build the base image before the configuration.

I do not track that in the company, but I am sure we have seen an ROI.

It seems to be fair. It is not overpriced. I went to the simple model, and that makes it easier for us to deploy.

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

When I worked for an MSP, we had a lot of requirements for Linux servers. Any customer services that were deemed to be on Linux were on Red Hat 6 or 7. In fact, a good forty percent of our estate was on Red Hat 6 or 7.

Red Hat Enterprise Linux's built-in security features simplify risk management. The operating system is very secure, and we used tools like Puppet to further limit and lock down access with configuration files from a central location. This made Red Hat Enterprise Linux both more secure and easier to configure. The fact that Red Hat Enterprise Linux is open source means that there are a wide variety of tools available to help with security, and the lack of a user interface for some of these tools makes them even more secure.

Maintaining compliance is easy. We used another tool called Spacewalk to deploy patches and update RPMs. It was very easy to connect to a repository. We didn't have any problems with that either.

The portability of applications and containers built on Red Hat Enterprise Linux is beneficial for keeping our organization agile. Red Hat Enterprise Linux is a lightweight operating system that can be deployed on a variety of hardware platforms, from small clusters to large industrial servers. This allows us to easily move applications and containers between different environments, which makes it easier to scale our infrastructure and respond to changing business needs.

Red Hat Enterprise Linux has helped improve our organization's efficiency by allowing employees to use a leave service to work remotely. One of the benefits of using Red Hat Enterprise Linux and other Linux distributions is that they are more stable and less likely to break than Windows. This makes it possible to automate many tasks, such as patching, which can save time and money. In contrast, Windows is more prone to errors and requires more manual intervention. As a result, Red Hat Enterprise Linux has been a valuable tool for our organization.

The time to value with Red Hat Enterprise Linux was quick. It took us only a few months to half a year to realize that we didn't have to do so much tweaking with it. We could just let it run and do its own thing, configuring it once at most, and then leave it alone.

Red Hat enables us to achieve security standards and certifications.

Red Hat Enterprise Linux helps us build with confidence and ensures availability across physical, virtual, and cloud infrastructures. We use PuTTY to connect to them. All of our SSH connectivity was locked down to be only from jump servers, so none of it was public-facing. This was a clustered approach, where users had to first connect to a Windows server and then use SSH or PuTTY to connect to the Red Hat Enterprise Linux server.

The ability to automate security configurations is very beneficial. Once we set it up, it can do its job very well without any further input from us. We found it easy to set up and configure, and it has made our lives a lot easier.

Red Hat Enterprise Linux helps to implement and manage security best practices with reduced overhead.

Red Hat Enterprise Linux has made our lives a lot easier. It is one of those tools like Terraform that takes a lot of the time constraints away from us. This is because we can leave it to do its own thing, and we know that it will do what it is meant to do properly. I think this is because Red Hat Enterprise Linux is lightweight and has a single purpose. As a result, it only needs to be concerned with that purpose. For example, we only have one role for that server, and we are happy and content knowing that it will perform that role.

Red Hat Enterprise Linux is lightweight and can be run on almost anything. It is a valuable product because it can do its job almost perfectly even with limited resources.

Although the price is reasonable, there is room for improvement in order to stand out from other open source solutions.

I am currently using Red Hat Enterprise Linux.

The stability of Red Hat Enterprise Linux is extremely good. Red Hat Enterprise Linux is lightweight, so it does not consume a lot of resources. It can handle a variety of workloads, and we have never had any problems with servers crashing or other issues. The software is also easy to set up and configure, and it runs smoothly once it is up and running.

The system's scalability is good. We deployed it across multiple locations, departments, and other areas. I give scalability a nine out of ten.

The support team is very helpful and knowledgeable about the product. They knew what they were doing and were able to resolve any issues I had very quickly.

Positive

We previously used CentOS. We still have Windows servers, and they can be a bit of a headache. However, we have since moved from CentOS to Route 6 and 7, and we found that this improved things a bit.

We switched because we had a better partnership with Red Hat themselves.

The initial setup is straightforward. We used Terraform to make it even simpler, but I don't think it was complex, to begin with. Deployment for one server takes a couple of hours. If we're just looking at a single server, or if we're building out a small cluster, deployment may take a day or two.

From a technical user perspective, we have seen a return on investment in terms of efficiency. This is because we can now set up a server and let it do what it needs to do without having to babysit it with patching, updates, and upgrades. This frees up time for engineers to work on other tasks, such as developing new features or fixing bugs.

The price is reasonable. I think it's a good value for what it is. It's not overpriced or extortionate. If it's something that's right for our environment, our infrastructure, and other factors, I think it's definitely worth considering. I don't think the price is a major concern.

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

I think open source software is generally cheaper than Red Hat. However, I don't think that cheaper software is always better. And I don't think that Red Hat is necessarily better than open source just because it costs more. It really depends on our specific needs. If we're comparing Red Hat to an open source equivalent, I would say that Red Hat would probably be a better fit for us. This is because Red Hat offers support, a back-end, and a team of experts who can help us if we need it. With open-source software, we're often on our own and have to figure issues out on our own. With Red Hat, we have the peace of mind of knowing that we can get help if we need it.

We have Red Hat Enterprise Linux deployed across multiple contracts and multiple data centers. It was not on the cloud; it was all on-premises. However, we were able to deploy it across multiple data centers, multiple customers, and multiple departments. This flexibility was a major advantage.

We used Red Hat Enterprise Linux to patch and update the system, including drivers, the OS itself, and security updates. We also monitored disk space usage and swap usage, but this was not too time-consuming. We had a team of three or four people to rotate tasks, so no one person was stuck on the same thing all the time.

Red Hat Enterprise Linux is a good product. It has a good ecosystem and support. It is lightweight and does what we need it to do. It is a good alternative to Windows for lightweight containers or servers. It is also good for specific roles.

The operating system is a great way to learn about Linux. While some people will always choose Windows, it is not always the best answer. Red Hat Enterprise Linux is more stable and less resource-intensive than Windows, and it is also more trustworthy. This makes it a good choice for environments where reliability and security are important.

I worked with different organizations. So, the use case varies from organization to organization. Right now, some of the teams are using it for applications like BI, and then there are a few others that are using it for Websphere, middleware, etc.

In terms of the version, most of them are on 7.9, but there are a few on 8.2 and 8.4 as well.

It enables us to achieve security compliance. Our security team is quite happy, especially in terms of patching up our servers, etc. It's compliant with our security requirements. With Windows updates, sometimes, there could be errors and the blue screen issue, and it could become hectic for the applications as well. Our security teams struggled a bit to update Windows, but when it comes to Linux, they are quite comfortable because they know that things will go smoothly.

I'm quite new to this organization, but I know that there has been improvement in terms of performance. We're using Red Hat Linux on Power Systems, which is quite different from the Intel platform. So, admins are much happier, and they are using it quite well now. Previously, we were using Windows for our applications, but now, we have made Linux mandatory for being open source and not bound to Windows. Things can be complicated on Windows. Especially when we're installing it, there are a lot of things, such as registries, but Linux is easier for admins. There is DVS as well.

When I worked in the banking sector, the most important part was user administration where you need to keep things under control for a specific user. The auditor usually looks for an agent or something like that, and it has been quite easy to manage things from that perspective. Things are more manageable now than in the past.

Windows operating system is used everywhere. You will find it everywhere, and every user is able to use Windows. If a user is using an operating system from the start, it becomes easier for them to use it when they come to a professional environment. That's an area in which I believe they need to put in extra effort, especially for the students. Currently, for their final projects, most students use Windows, and this is an area where Red Hat needs to put in an effort. They need to give some training to the students so that when they come to the professional environment, they're already used to it. It would then become easier for them to use it in a professional environment.

I'm also using IBM AIX, which supports a tool called Smitty. You just put Smitty, and you can do anything. At the backend, the command will run automatically. It is not exactly like a GUI, but you just give the input and it will give you the output. That is something that Red Hat should work on. That would be an added advantage with Red Hat.

It has been 12 or 13 years.

It is very stable.

We are mostly using VMware and Power Systems. Scalability-wise, they are always the best. We can upgrade to get all the resources on the fly. We never faced any issues. However, if you didn't add the required parameters on your profile on VMware or the Power System, then there is an issue, but that's not related to the OS. That's related to virtualization.

Application-wise, there are multiple teams that are using these systems. We have the database team, the middleware team, the MQ team, etc. There are also system admins. The system admins are the ones who are deploying it, but the owners of the system are different.

We have plans to increase its usage. Two years ago, we had only 60 or 70 servers of Red Hat, but now, we have 400 to 500 servers. Its usage is always increasing. After a year or two, we might end up with about 1000 servers.

We have contacted them a few times. We did ask the support team to get in when the cluster got stuck and let us know what's the issue and what's the solution. Whenever I have asked for support, they have provided the best support. I always count them as the best. We have never faced an issue with them. I would rate them a 10 out of 10.

Positive

We had Windows. The stability was the reason for switching to Red Hat. The stability of Windows varies, but Linux is quite stable now. That was the main part they were looking for.

We are very comfortable with using Linux. We have been using it for 10 to 15 years, and we can't switch to Windows. We can't use Windows even on our laptops. We are not used to using a mouse and GUI. The command prompt is much better for us.

We also use AIX because we have AIX infrastructure, but a few of the applications don't work on AIX, whereas they work with Red Hat Linux. That gives Linux an advantage. So, we use Linux on Power Systems, rather than AIX.

We have been working with different operating systems, and we also know most of the technical requirements, so it is easy for us. Usually, the OS installation takes a maximum of 25 minutes. If you are making extra file systems, such as for Oracle, it takes 10 to 15 minutes extra. A desktop or a single file system doesn't require much time. We already have scripts. We just run the scripts and everything is done by the scripts. Previously, it used to take two or three hours, but now, things have changed, and we're making life easier.

We deploy it ourselves. We don't ask other vendors to deploy it for us. In terms of maintenance, we have already been updating our maintenance contracts, especially the support contract. There are some old systems running in our environment, and we are in the process of upgrading those from version 6.9. We already have the required support.

There are four people on the team, but for Linux especially, there are only two people. We're easily managing 500 to 600 servers for Red Hat.

When you are running your infrastructure on this, you can always find some discounts with local support, etc. There are always some discounts to match your budget. It is definitely affordable. 

When it comes to virtualization, there are different factors. There is not only Red Hat. There is also IBM, VMware, etc. The third-party vendors always manage to come up with a good offer. Our company can't say no to that, and it works out fine.

We also have IBM AIX, and when you compare these two, there's a huge difference because IBM AIX's support is quite higher than Red Hat's.

To anyone interested in using Red Hat for the first time, I would definitely advise starting with the GUI because now, the GUI option is quite good, and you can do all the things. After that, you can slowly start moving to CMD. For learning, there are a lot of resources available online, such as YouTube and LinkedIn Learning, whereas Red Hat Academy is quite expensive.

The biggest lesson I have learned from using this solution is that when you're using the command line, you need to be extra careful. That's because when using the command line, a single slash can make a huge difference. That's what I learned at the start of my career.

I started with Red Hat Version 5. Now they have version 9, which I haven't used, but if I just consider the evolution from version 5 to 8, 8.2, or 8.4, there has been a huge difference because, at that time, people were scared of using Linux, but now, things are different. There has been a revolution in terms of OS. A lot of things are being changed, but in terms of the things that we do, for us, it is the same because we are doing system administration. As a system admin, there is nothing different for us. We are doing the same things again and again because the applications require the addition of storage.

There is also a change in terms of security features. If I compare the old versions with the new versions, in old versions, adding any exception in the host firewall was a real task, but now, things have either become smooth, or we have gotten used to it. Overall, for me, things have become easier. They are getting more and more secure, but with the vulnerabilities and the assessments that have been done, we need to keep updating. Now, everything has caught up with the latest security required in the market.

In our environment, we're using virtual servers. There are no physical ones. We are shifting to containers in my current organization. Most of the applications we are using are containerized, and it has been easy for us to manage those applications. However, we also require some in-built applications, and for that, a change in people's mindset is required. It's not about the OS; it's about the people who do the development. It is becoming a bit hard for them because they were using a different platform previously, and now, they need to move to the Linux platform. It is a little bit different for them.

Overall, I would rate it an eight out of ten. When comparing it with AIX, AIX is a bit easier in terms of use and it also has the Smitty tool.

I am a database administrator, and we mostly use Red Hat Enterprise Linux to manage databases. Primarily, we use it for Postgres, as it works best on Red Hat Enterprise Linux (RHEL). It's easiest to set up and has the best documentation.

I'm aware of one customer that is thinking about it. But I'm not sure what specific projects they want to use it for. I think there's one customer who is interested in it and is trying to find a solution that might benefit from it. 

Red Hat Enterprise Linux (RHEL) contributes significantly to our business continuity and compliance efforts. The best example is uptime. Many critical businesses need to be operational twenty-four hours a day. If a database goes down for some reason, it is seldom Red Hat Enterprise Linux that is the issue. This provides peace of mind.

It has helped us centralize development because Red Hat Enterprise Linux has many tools that aren't accessible to our Windows customers. 

Red Hat Enterprise Linux's most valuable feature is its reliability. I don't have to worry about the operating system. It's one of the easiest operating systems for databases, and the integration is excellent. It gives me peace of mind because I can focus on my database work without worrying about my OS. I want to ensure I have applications that run on the OS without searching for temporary fixes or workarounds. 

It has some of the best out-of-the-box security features of any Linux distributor. Red Hat Enterprise Linux has more built-in security features than most standard flavors, or it has implemented them better. 

I haven't identified anything that needs to be proved, but I hope Red Hat Enterprise Linux maintains its reliability.

I have used Red Hat Enterprise Linux for the past five years.

Red Hat Enterprise Linux has been perfect. My Windows customers experience a lot more downtime and bugs. Our critical businesses need to be up 24/7. It's rarely its fault if a database goes down. I would estimate that there's about 10 percent less downtime compared to Windows customers. 

I haven't been involved in any real project that necessitates scaling as our needs change.

The support is excellent compared to other solutions like Oracle. They're knowledgeable and easier to work with. We have a nice, transparent working relationship.

The biggest ROI is from Red Hat Enterprise Linux's reliability. If I run databases on Windows, I have to find other tools or workarounds. It's a big hassle. Red Hat Enterprise Linux lowers the total cost of ownership for my customers because I bill fewer hours than I would in a Windows environment. Open-source databases run better on Red Hat Enterprise Linux than on Windows. Most things I need are built-in or can be downloaded from the repo. 

Ubuntu is commonly used, and there's a decent amount of documentation for databases, but it can't compare to Red Hat Enterprise Linux. Setting up Postgres or any open-source database on Red Hat Enterprise Linux is way easier. The documentation is more extensive. It's also easier support because many customers have a subscription with Red Hat.

I rate Red Hat Enterprise Linux nine out of 10.

My advice would be to focus on reliability and ease of integration when choosing a Linux OS. 

Our core business is delivering IT services to public companies, and most of the applications run on Red Hat Enterprise Linux.  We use Red Hat Enterprise Linux to host machines that various teams of developers use. Most of the time, we use Red Hat Enterprise Linux to run websites and various software applications, including CMS tools like Drupal, SIP, and Azure CMS. We also run business-critical applications on Red Hat Enterprise Linux. We're still looking to migrate everything on the mainframe to Red Hat Enterprise Linux, and our middleware databases run on it.

While we don't have any containerization projects yet, we have a few in the pipeline. We plan to add some new Docker clusters and Kubernetes clusters with OpenShift. The presentation on AI workloads looked interesting, but we must implement OpenShift containers first and enable AI tools. 

Red Hat Enterprise Linux is quite good for business continuity. The system has supported some applications and businesses fine for years without any patches. It's highly robust, which is one of the main reasons we continue to use Red Hat Enterprise Linux. 

Red Hat is based on Linux, so the security is more stable than in other systems. For instance, we cannot reuse machine credentials. We use key certificates to connect to the machine. It's not like a user password. Without a key to access the machine, you cannot do anything. There are specific controls on user access, and you can limit the privileges.  

Using Red Hat Insights with a Rapid7 tool, we've avoided breaches by detecting and patching vulnerabilities early. Now, we're using the Ansible Automation platform to manage the system better and provision new VMs more efficiently. 

We've built scripts that have not performed well internally. They can cause problems, but we're using the Ansible Automation Platform to avoid such problems. For instance, a script for creating VMs on VMware and deleted some. That has no longer happened since we implemented Ansible.

Although we are happy with the current capabilities, we would welcome new features, particularly in the AI domain.

I have used Red Hat Enterprise Linux for about five years, but my company has used it for around 10 years.

Red Hat Enterprise Linux is very robust and stable.

Red Hat Enterprise Linux is scalable, and provisioning new setups is more efficient with the Ansible Automation Platform. 

I rate Red Hat support eight out of 10. 

Positive

We joined the company when Red Hat Enterprise Linux was already selected, mainly because of its support and security aspects.

The robustness and support provide the biggest return on investment. It ensures stability and security for critical applications and helps deliver IT services effectively. The support behind it is excellent.

Red Hat Enterprise Linux lowers the total cost of ownership. We have 65 percent of our VMs running on Red Hat Enterprise Linux and 65 percent of the business we provide to our customers is based on the platform. 

The pricing and licensing, especially for options like the Red Hat Enterprise Linux Ansible Automation Platform, are quite expensive.

I rate Red Hat Enterprise Linux nine out of 10. I recommend going with Red Hat Enterprise Linux because it's excellent. I asked a security team colleague why they don't use Red Hat Enterprise Linux, and he couldn't say why. It's one of the best from our perspective, and the support behind it is superb.
