As a developer, I use both SUSE as well as Red Hat Enterprise Linux. My personal preference is Gentoo, but no one runs Gentoo on a production system. Gentoo is better in terms of customization. You can choose what you want.

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.

We also use SUSE Linux and have some implementations that come packaged as an appliance from various vendors. We also have some Ubuntu requirements but those are not managed by the internal Linux operations team.

I've personally used everything from Slackware to OpenBSD, FreeBSD, Red Hat, Fedora, and Ubuntu. I've used everything.

I like the way that everything is predictable with Red Hat Enterprise Linux. You know what you're getting. You know where everything is, and you know that you can find support if you need it. When we're upgrading or if we're adding something, I always know where I could find what I need to find.

I have mostly been working with Red Hat Enterprise Linux. 

I came from a Unix background. I was on HP-UX on OSS and AIX. So, the transition to Linux was very simple. I am a command line person, so I wasn't scared. I just moved into it and found it to be very attractive. In fact, I don't run GUIs on any of my Linux boxes.

The biggest benefit for me, coming out of the Unix arena, was that it matched Unix very closely. So, I am able to draw on my Unix experience and use that in the RHEL environment. There is almost a non-existent learning curve in my situation.

We have always used Red Hat, but they use CentOS for a few applications. Most are using Red Hat. Another team uses Microsoft Windows 2016. It's a different team. The application team decides which one they prefer, but most clinicians use Red Hat Enterprise Linux servers.

The application owners like Red Hat instead of CentOS or another flavor of Linux because the support is reliable. If something breaks, they can call Red Hat support. It's the enterprise standard Linux.

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.

Primarily, we have used Ubuntu. We have had some of our use cases on CentOS, and then, of course, our workstations are all Windows, but I wish they were not.

We chose Ansible, and that chose Red Hat Enterprise Linux for us.

In the past, our work primarily involved Hadoop, and we also dealt with Solid Cloud for security and other purposes, but we found that this setup was slow and not open source. On the other hand, the DLP solution we're currently using is not only cost-effective but also significantly faster. 

I also used a Linux browser, specifically the KCL browser which required me to go through the process of installing packages and various components, while in the current setup, everything is seamlessly connected. We simply use the OC command with a private key to connect to OpenShift. There are no extra or additional steps required, making the whole process exceptionally fast and efficient. It's quite remarkable and makes the workflow truly hassle-free.

We previously used Debian, Ubuntu, and SUSE Linux. In our case, if we wanted a conservative Linux system that did not have the newest version, these were perfect systems. However, if we wanted to install them on our laptops or on our clients, they were the wrong solution. We switched to Red Hat Enterprise Linux for the Red Hat support. Debian also offers its own support. Ubuntu does not offer direct support, so we were required to order it through another company. SUSE had other problems that we did not want to deal with. Red Hat Enterprise Linux support has been very helpful to our back-end admins.

I used to use HPUX and Solaris. We switched to RHEL because HPUX started looking like it was going away, so we started moving to Red Hat. We thought it was our best option. We tested different flavors of RHEL.

When it comes to provisioning and patching, we have a satellite server. We use a lot of Ansible. We are getting used to Ansible and Satellite servers. 

Before I started working for the organization I work for now, I used a product called the FOG Project. At the time, we used Ubuntu Linux. FOG was the equivalent to Satellite and Ubuntu is the equivalent to standard Red Hat.

Comparing the two are apples and oranges. The FOG Project is not as mature as Satellite; it doesn't have the bells and whistles that Satellite does. In general, their lifecycle management tools cannot be compared. Satellite outperforms the FOG project, it's easier to deploy and easier to use.

When comparing Ubuntu and Red Hat, the big difference is that the releases for Red Hat are more stable. They do lag a little behind Ubuntu, as Ubuntu is more bleeding edge. This means that they're pushing out updates a little bit faster, but they're not clean in the sense that they may push out a patch, but then five days later, they have to push out a patch to patch the patch. This is in contrast to Red Hat, which is a little bit more consistent and a little bit more stable. What it comes down to is that Red Hat is much more stable than Ubuntu in terms of patches, updates, and upgrades.

Those are the key differences for somebody who manages that infrastructure. You want something that's easy to diagnose, troubleshoot, and put out solutions. Ubuntu may push out a patch or an update that's so bleeding edge or so out there that vendors haven't had time to come up with solutions on their own, so if it's a driver issue or something like that, with Ubuntu, you may have to wait around as a user for those kinds of solutions.

With Red Hat, they make sure that when the product goes out, that there is some Q&A, and they've done some testing. They make sure that there's compatibility with other products that depend on that particular feature, functionality, or service.

We use RHEL and Canonical. We have some SUSE implementation in the Linux area. In hypervisors, we use VMware and Hyper-V. So, we are in many different technologies, and we are not always on RHEL. RHEL has almost 45% of all our hardware. It is the biggest one, but we use almost all the solutions. In terms of security, Red Hat and Canonical have almost the same level of security.

Previously, we used CentOS. We have also used Oracle Linux, which is based on Red Hat Enterprise Linux's kernel. Now, we're strictly trying to use Red Hat Enterprise Linux. We switched to Red Hat Enterprise Linux because it provides great support.

The products are pretty similar. A lot of the implementations, commands, and updates are very similar. Overall, we've had a more positive experience using Red Hat Enterprise Linux. We have a basic build routine when building new servers, updating, and installing add-ons. When we run those scripts, it seems like it's so much more streamlined with Red Hat Enterprise Linux. It could be because we're converting everything to Red Hat Enterprise Linux.

I was using AIX, which is also an IBM product. IBM bought Red Hat Enterprise Linux. AIX was more expensive and required IBM System p. Moving to Red Hat Enterprise Linux was much easier because it is a lot more compatible with the regular hardware like HP and Dell that we buy on the market.

We run Red Hat Enterprise Linux in parallel with other OS systems. We are satisfied with how well Red Hat Enterprise Linux works with our other products.

We use Red Hat Satellite for managed services for our customers. And, of course, we use a product of Red Hat Enterprise Linux for servers. We started with OpenShift in the lab at the beginning, but now I'm beginning to produce it for our own services. So, now I can offer these to the customers.

One of the discussions in my company at the beginning of this year was to see if we could test our services on-premises for the virtualization, specifically for the KVM virtualization. But since it was not approved, we'll have to see the next step.

I have worked with other open source distributors. I have worked with SCO-Linux and Unix, which is the base of Linux. I didn't personally make the decision to switch. The company decided to switch since we are partners, and we are focusing on putting in the best efforts in terms of the partnership and customers we have with Red Hat.

We still use other operating systems. We've used just about every solution you could name in conjunction with RHEL. We also deploy Ubuntu. In some cases, our application vendor requires us to stick with a given solution. Sometimes it's AIX or Solaris, but mostly we can override that and move to RHEL. Red Hat is now standard for most future enterprise deployments, and we run RHEL on mainframes too, but in a very limited fashion.

We are switching to another solution mainly because a number of databases in use are based on that system. They want to expand that database and some other products that come with switching from RHEL to LEL. That's the main reason. As I understand it, the licensing isn't that different with a more centralized approach, so convenience is a large factor.

We switched to RHEL from AIX because of the developer and the cost. AIX is usually implemented on specific hardware. IBM owned the hardware. So the cost for running AIX is a lot more expensive than running an RHEL solution, which can be run on virtual systems as well as physical systems. And x86 servers are a lot cheaper than a power system.

Open-source was also a factor in our decision to switch to RHEL. Open-source has allowed a lot of development in areas, more ingenuity, innovation, and products than other constricted OSs. My opinion is that when you're dealing with open-source, you have people who are more likely to innovate and create new things. It's easier to develop an open-source platform than it is to use a closed source platform because then you can't get to the APIs, you can't do anything in the system if you want to change things in the system to make your product more available to people.

We had Satellite and Red Hat Enterprise Linux from the beginning, but we also use other flavors like Amazon Linux. 

Our environment is hybrid. Most of our Red Hat Enterprise Linux is on-prem. For the cloud, AWS is the cloud provider, but we are using a different distro for AWS. We use AWS Linux for that. For on-prem servers, we're strictly using Red Hat Enterprise Linux. For desktops, we use Fedora.

The reason for using AWS Linux is that we only have AWS. If we use multi-cloud, for instance, if we use Azure and AWS clouds together, we would definitely need something other than AWS Linux. AWS Linux is very solid too, and our team likes it. We can download the AWS Linux version for on-premises too. I've done that. I tested it, but we're sticking with Red Hat Enterprise Linux.

In the server space, nothing comes close to Red Hat Enterprise Linux. I know that Ubuntu is making a big push, and some people have gone ahead and migrated to Ubuntu, but I think those are going to migrate back. There's just no comparability. They're different. They're like cousins. They're very similar in some ways, but they're very different things. You can install SELinux on Ubuntu, but why bother and why go through the whole configuration? Red Hat Enterprise Linux is more suitable for servers.

I have personally used Solaris. However, we eventually switched from those operating systems, but Red Hat Enterprise Linux has been there since version 4.2, a long time ago. I have worked with versions 7 and 9, and I believe the latest one is version 11, although I'm not certain. I have been immersed in technology for the past couple of years.

One of the most important factors is the community. The Red Hat community is different from others, and it is more active and responsive. If you have Red Hat Enterprise Linux and you want to move your production environment from development or testing, it is easy to switch by simply managing the licensing and purchasing the system. You don't need to make extensive changes at the underlying system level. Your system is ready, and you can deploy it in the production environment. It's up and running. If you want to mitigate risks and ensure security in your production environment, you can simply subscribe to RHEL and use it. On the other hand, migrating from other operating systems can be quite cumbersome and challenging. As a client and partner, I always recommend starting with Red Hat Enterprise Linux in the development and testing environments before moving to production. It makes the journey to production much easier.

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 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.

We also utilize other Linux operating systems depending on the use case. SUSE Linux Enterprise is more optimized for SAP products. When working with an Oracle database, it is preferable to use Oracle Linux.

We had CentOS systems. When they changed upstream, we had to pivot some systems. We pivot some systems to Oracle Enterprise Linux, but then those eventually got transitioned to Red Hat as well.

The main reason for the switch to Red Hat was for the government customer and having a support contract. You can do Oracle Enterprise Linux without a support contract, but if you're going to buy one, you might as well get Red Hat at that point for the added benefits.

We use Kali for a couple of other use cases, and we probably won't replace it with Red Hat.

We've used a lot of flavors of Linux. One thing that sticks out for me, even in just the home lab environment or deploying at work, is that if there's some backward thing that we weren't planning on going into, if I look for a solution, nine out of ten times, I'm going to find an article on Red Hat's website where somebody has either a verified solution or somebody is talking about it and there are comments that are relevant. I hate going on ServerStack, Ubuntu Stack, or something like that, where somebody has the exact problem that you have, but there are no comments and no answers. I find that to be less true with the Red Hat platform.

I have experience with most Linux operating systems, including distributions like Apache, Debian, CentOS, Fedora, and others. From my perspective, Red Hat Enterprise Linux is not necessarily the top standout product, but I know that it is a product that I can rely on. It is the standard image that enterprise users in the community will use. We can rely to a degree on the standardization of how packets are used to support it. However, it does not stand out to us as much as the other products. Nevertheless, I know that it will have a positive partnership with us. Red Hat Enterprise Linux is a more suitable operating system for enterprise environments in terms of stability and reliability.

Ten years ago, I used VMS and AIX depending on the project. 

My job right now is on analytics-based systems so I use the solution. The organization has used it for twenty years. 

We used some open-source Linux flavors that are now obsolete and CentOS. Red Hat Enterprise Linux provides excellent support for migrating from CentOS to Red Hat Enterprise Linux at any level, so kudos to Red Hat for that. There is a great tool that enables us to migrate an existing application without any changes, so we can convert CentOS boxes.

There are one or two commercial Linux flavors that can compete with Red Hat, but their based on different architectures. Red Hat has a large portfolio, including OpenShift and SQL automation, offering deep integration between these tools. I don't think there is a competing product that offers a comparable product portfolio because Red Hat is under the umbrella of IBM now and also provides a multi-cloud solution. 

We used CentOS. It's a different setup than Red Hat. CentOS is also a Linux-based distribution. CentOS is open-source, so we don't need to pay for it. Compared to CentOS, Red Hat has advanced features but the cost is still high, so it's problematic for medium-level customers.

We switched to Red Hat because the service providers like high-performance computing. We mostly have high-performance computing deployed in our data center. We needed Enterprise Linux as a minimum requirement. Red Hat Enterprise Linux supports high-performance computing solutions, and packages have to be installed from their repositories. That's a must for any IT enterprise organization now.

CentOS is an open-source solution and provides 70% of the features that Red Hat provides. We pay Red Hat for the repository and application support.

It has a great set of dependable packages, software, and a collection of utilities embedded in that operating system. We don't need to get apps from the repositories. There aren't a lot of errors in the Red Hat operating system, which makes it useful for our system administrator.

I used to work for a government organization that was heavily into AWS. One of the reasons they embraced open source was because Oracle was too expensive. They put everything into AWS rather than open source, so they will soon be in the exact same position where everything is proprietary. 

I've been with my current company for 10 years. We've used other UNIX platforms, like Solaris and AIX, but those are for different use cases. The company I started at, which was bought, had seven different implementations and I standardized them on RHEL, before the acquisition.

We switched to RHEL because those seven different operating systems were supporting a single team and none of them had a great management infrastructure, or they were just plain open source with no support. And getting to a single, supported, managed environment was the goal.

Red Hat's open-source approach was a factor when we chose the solution. I'm a big fan of the entire open-source consortium. The more people there are who can look at the code, validate it, and make sure it works as it moves upstream into the solidified package that Red Hat supports, the better. It gives you more visibility, more transparency, and you can customize it more. Whereas with closed code, you have no idea what's going on in the background.

My company also uses MariaDB as a database, while at times, we use databases from Oracle or PostgreSQL over RHEL.

Sometimes, I use Ubuntu for some of the end-users in my company. Red Hat Enterprise Linux (RHEL) is useful for servers and not for end users. Red Hat Enterprise Linux (RHEL) is very compatible with servers.

We did previously use a different solution. 

I previously used Canonical in other open-source projects and pushed for a switch to Red Hat because of my familiarity with it in past projects. My current employer does not utilize Red Hat Enterprise Linux because of the high cost.

We prominently use RHEL, but we've also used Ubuntu. We also have used PCF. I use Ubuntu Xenial and have worked with Amazon Linux for a while.

One pro is that at the operating system layer, RHEL has better support from Red Hat, and if something goes down, I found many resources for troubleshooting online.

For example, we predominantly use Amazon Linux if I'm using AWS. There aren't a lot of resources if I run into an issue. RHEL has way more documentation on Linux. It has a bigger community, from an operating system perspective.

I have used Ubuntu, CentOS, openSUSE, and Mint. Red Hat Enterprise Linux definitely has an edge in security and the ability to control what the user at the end stage is doing. However, it is difficult to learn.

We tried quite a few flavors of different things, but nothing provided the consistency that we are getting with Red Hat Enterprise Linux. We tried everything such as Ubuntu, Mint, etc.

Red Hat Enterprise Linux stood out for its consistency and stability. We had several different problems with drivers on Mint. There were so many different flavors. We had one developer who built everything on one, and then another developer built on another, and none of that was coming together. It was not meshing, so we finally went to a common platform with stability and supportability. It was a lot better. It has allowed the developers to focus more on their code rather than having to worry about fighting the underlying things, such as drivers aren't on this one, and that one is not working.

I have used Fedora and Oracle Linux. I have some systems that run CentOS. 

Our organization requires us to use different solutions. We have had instances where products were developed on Oracle Linux. These products are medical, and switching to a different platform is not a simple task. I am encouraging the organization to switch everything to Red Hat Enterprise Linux because, although Oracle Linux is a fine platform, it is eight months behind Red Hat Enterprise Linux.

The main benefit of CentOS is its cost. Both systems are reliable, but Red Hat Enterprise Linux has a major advantage: Red Hat support. With Red Hat support, we have access to top-level Linux experts. If we need help with anything related to Linux, we can call Red Hat and they will connect us with an expert who can help us.

I previously used Ubuntu Linux and SUSE Linux Enterprise. I switched to Red Hat Enterprise Linux because it has better support. I haven't tried the others, but Red Hat looks like it has better support. However, Ubuntu is more compatible with desktop development, making it more user-friendly.

I have used CentOS and Debian.

I also use Oracle Linux which is the same as Red Hat Enterprise Linux. Everywhere that I deploy Oracle Linux, if I deploy Red Hat it works fine.

We had some smaller setups with this where we had some room for development, but now we're trying to standardize everything using smaller footprints, and not having to manage more workspace stuff. Now we're pretty much in RHEL and working on that.

I was part of a working group who decided which major enterprise distributions we would introduce into our organization. Before 2016, we only used a very small number of Linux installations and different distributions. As an outcome of this working group, we decided to use RHEL and have used it since as the only distribution in our data center. We migrated from other distributions, such as SUSE Linux Enterprise or openSUSE, to RHEL.

While all distributions share a Linux kernel, there are differences in how to manage the distribution itself. A very important part is the package management. When you have to deal with tasks like updating packages, downgrading packages, and repairing damaged package databases, you want to have one package management tool that you know very well, not three different package managers where you only know the basics. To ease the management of multiple hosts, we decided to migrate to only one distribution. We hoped that we would have an advantage in consolidation. 

Before 2005, I worked as a Unix engineer for Solaris and Sun Microsystems. Once I left that company who was working with Solaris, that is when I started being more like an administrator for Red Hat Linux for different companies.

We used Oracle Linux before we moved over to Red Hat Linux. We likely switched due to costs and licensing. We also use Windows extensively. Since we used the same architecture, we didn't need to use any third-party applications.

I have used Linux distributions but when it comes to the work I'm doing at my company, we always use Red Hat Enterprise Linux. 

The biggest differences between Red Hat Enterprise Linux and the other OS' are the support, Satellite, Insights, and the fact that Ansible was acquired by Red Hat so you can use all its automation and toolings. The entire ecosystem works very well together.

We still have Windows servers.  

Red Hat Enterprise Linux is very resource-intensive, and it's hard to secure because Windows, the base use case, is all things to all people. 

I generally like Linux server products. I like the way they specialize, and I like the default security posture.

I have used different OS like Motorola, Unix Flavors, Solaris, HP-UX, AIX, DG/UX, and Sonos OS. Unix is dying, and everything is moving to Linux. Linux is open-source and easier to use. 

We did use a different OS. I have used Unix in the past. I started with Unix 30 years ago. I've also used SUSE. Red Hat offered more service and support. 

One of Red Hat Enterprise Linux's pros is that it has been around the longest. When working in a large corporate environment, reliability is crucial. In case something breaks, you want to have the assurance that there is a reliable support system to address the issues. Red Hat Enterprise Linux provides that level of support. 

However, it's important to note that even with a solid distribution like in Red Hat Enterprise Linux, the effectiveness may vary depending on the specific customer or scenario. It's about assessing how well the distribution handles issues when the next customer raises a complaint. So, we need to carefully consider the pros and cons based on our requirements. For certain workloads and development tasks, we might consider freestyle options that don't require paid subscriptions. In my company, we have a development program that greatly supports our decision to go with Red Hat Enterprise Linux.

I previously used AX, HP-UX, and Solaris at a prior job. My current employer has always used the solution. 

We previously used Ubuntu, but RHEL has more features. We are running Windows in parallel for a few of our applications.

We mostly had Microsoft solutions, and we were using Windows 2012, and we had some issues with it. Working with Windows was really painful for us as administrators. For users, there was no issue. The servers were always working. We switched to Red Hat because it had the biggest offering. It is an enterprise solution, and it gives you all the things. With others, you have to do things on your own. It is a complete solution.

When we migrated from Windows 2012 to Red Hat, it was a game-changer. In the beginning, we were working with IIS for deploying applications. Most of the applications were developed in the company, and some of them were not PHP-native.

We also have four servers using Debian Linux, and we have another software that is open-source and built from scratch. It is like Red Hat, but you need to do most of the things from scratch. We're using Docker instead of Kubernetes for everything related to quality assurance for our developers.

I have used Ubuntu, which has its own cloud service. Red Hat Enterprise Linux is a better option if the client has a budget. Red Hat Enterprise Linux can be certified and meet compliance requirements. 

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 also use CentOS for educational purposes. Support and regular updates are advantages of Red Hat Enterprise Linux over others. 

For directory servers, we always use Microsoft because it is easy to manage and easy to control. Implementing and managing domain controllers on Microsoft is easy, and we can apply policies by groups (GPO).

We've used Windows, Solaris, and AIX. The reason for switching to it was that everything is moving to the black box. People want everything to be secured. We got a lot of updates on Red Hat, and it was doing very well in the market.

We previously used Windows but switched to Red Hat Enterprise Linux for cost savings.

Previously, we used HP for our database site before transitioning to Red Hat Enterprise Linux. As we were already utilizing Red Hat Enterprise Linux for our applications, it proved to be a more optimal choice for our database site as well.

I have got experience with Windows and Solaris before that. Red Hat Enterprise Linux is my favorite. With Solaris, that stream stopped a long time ago, but Red Hat Enterprise Linux has all of the nice things about it, and they have continued to develop and build many new things. For instance, when you had to patch on a Solaris box, you had to take the server down into single-user mode and apply the patching. I like it better than Windows in every way. It is more intuitive to me. I like that I can do more things from the command line. It is easier to automate things.

We're using a lot of different OSs. We use Red Hat Enterprise Linux because we are a partner.

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. 

A lot of my clients used to use Oracle Solaris, but many of them switched to Red Hat due to hardware costs. Oracle hardware is expensive, but it is good stuff. We had systems that ran for three years without any issues, but it gets expensive if something breaks or you need to replace hardware due to the lifecycle. 

You can install RHEL on any x86 hardware and deploy it on several Dell servers, which is much cheaper than a single Oracle server. For example, we needed to replace a system because the hardware got sold. We were quoted a price for Solaris running on an Oracle T5. It was four times the price of replacing it with HP hardware. So that's the main reason many clients have shifted to RHEL. 

It's a vicious cycle. As more companies switch, other clients say, "Oh, but there's not much user base left. How long will this run? Let's follow the mainstream trend." That said, I love Solaris. It's unbelievably stable and easy to use, but just the hardware underneath it is too expensive.

I have worked with many different operating systems in the past, including Windows, Linux, and RedHat Linux.

We switched to Red Hat Enterprise Linux because it is a reliable and well-supported enterprise operating system. It is easy to manage, use, and upgrade.

We previously used Proxmox and switched to Red Hat Enterprise Linux because of the price.

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

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

I, for one, was managing AIX, which is a legacy Unix, as my core competency. I still do because we haven't completed the migration. 

RHEL is a value-add right now. As we are migrating more payloads to containers, we are putting less Linux forethought into these container-hosting servers. You just shove your containers on top of them with your orchestrations. This may reduce our need to manage RHEL like a bunch of containers. That changes the business. 

We were paying for premium SUSE support for an initial pilot of SAP HANA on the IBM POWER platform. We were stuck between an IBM organization telling us, "Go to SUSE for your support," and the SUSE organization saying, "Go to IBM for your support." So, we told them both to go away. 

We are so glad that we haven't mixed the Red Hat and IBM more, because SUSE and IBM don't mix, and we were mixing them. That was prior to the merger with Red Hat. In regards to IBM's ownership of Red Hat, we are a bit wary, but we think that IBM will have the wisdom not to mess it up, but we will see. There is a risk.

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

We are a mix of some other cloud virtualization technologies. The overall cloud information will define how we look down the road.

With Linux management, the pros are that it makes management a little easier. Overall, it is just a single view of the images we deploy in the organization. 

The cons are that the integrations are a little tricky sometimes, and then we have to make exceptions to our policies. Better integration, more native service using more credentialless authentication, and authorization like using service principles or managing these over-store credentials would make it better.

Previously, we used AIX. Now, we still use CentOS and Rocky for development.

We previously used Windows and Oracle but migrated some of those systems to the solution. 

I've used some open-source environments like CentOS and some other solutions like Solaris and HBOX. We switched to Red Hat because it's easier to deploy and manage.

Initially, I used Solaris because I liked it the best, but Red Hat Enterprise Linux has improved so much that it has overtaken Solaris. Red Hat Enterprise Linux is easier to use and has better documentation. I also like having the ability to use Satellite and Ansible automation to manage Red Hat Enterprise Linux. 

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

They were using Ubuntu.

We were mainly running CentOS, but then Red Hat dropped their support for CentOS. For us, our security posture is highly important. Our major pain point was around patching. Whenever we had any vulnerable web servers exposed to the public internet, we were not able to get patching for any CVEs that were found. That's why we switched our web servers to Red Hat. Patching was Red Hat's main advantage. In terms of security features and control, such as user management and permissions, Red Hat is quite similar to other distributions. I don't see any difference in terms of other aspects. The switch wasn't because of a lack of features, but after switching to Red Hat, we are now exposed to their enterprise features or tools, such as OpenShift. So, our investment in Red Hat was because of their support and patching.

We also use Red Hat Ansible and Satellite.

I have used Solaris, and I've used different distributions of Linux, however, not always in a professional setting.

It's an interesting situation because we use Oracle Enterprise Linux primarily. It is really not very different from RHEL because it's just recompiled and they resend it. We use RHEL on one of our clusters, which has about 300 nodes in it and is used in research. In short, we use both Oracle Linux and Red Hat Linux, but the reality is that nothing much is different between the two of them.

We initially implemented Red Hat and we consolidated everything to Oracle Linux because it was cheaper from a support standpoint. That was when Red Hat Enterprise Linux version 4 was out. I think that version 5 had only just been released and we switched to Oracle, which is the same thing anyway.

The last time the research cluster was updated, it switched from the IRIX operating system to Red Hat on HP. They weren't necessarily going to implement Red Hat but we had to make sure that everything was licensed correctly, and that's how it came into play. Since it is not using our Oracle license, but it's already bought and paid for, we have not consolidated it. We could consolidate again but it doesn't make a lot of difference in terms of what we do on a day-to-day basis. It runs the same and it operates the same.

We were running version 7 of Red Hat on the cluster and we have versions 4, 5, 6, 7, and 8 running in the Oracle Linux space. The applications running on version 4 will only run on that version, and there are only two of those left. We have three instances of version 5, about 30 running on version 6. We are trying to reduce this number and we had more than 60 running on version 6 a few months ago. The fact that this is going down is nice.

Versions 7 and 8 are still supported, so the specific version is not a concern.

Prior to using Linux, we used Digital's TruCluster. However, after Digital was bought by HP, they discontinued the product.

We've also used Ubuntu. 

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

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

We have been using Red Hat Enterprise Linux since I've been with the company. Linux is our platform of choice.

Prior to using RHEL, I was using Windows. I've also done a lot of work with Ubuntu, SUSE, and other Linux solutions, but Red Hat is the best one. I prefer it over other solutions because I'm used to it, and I find it better than other solutions. I'm used to the commands, and it is easy for me to navigate my way through it. If I have to choose between Windows and Linux, I would always go with Linux and choose RHEL because of its stability and agility.

I also use CentOS for my personal things or running some tests. For example, if I want to run a test with a client, it doesn't make sense to run a test in the client's production environment. I have a test environment with CentOS, and I run the test on CentOS before going to RHEL. I'm pretty comfortable using CentOS. CentOS is like my own testing environment.

The reason I switched over to RHEL was that over here, almost everybody or every client who uses Linux has RHEL. So, I had to understand how RHEL works. I realized that most people use it because of its stability. People find this system and its architecture good. A lot of clients talked about how they preferred the architecture of RHEL. Some clients find the commands to be easily readable, and some clients find it easy to integrate with others. A lot of clients find patching and package management pretty easy.

We were using Solaris 10. We moved to Red Hat Enterprise Linux because it is cost-efficient and hardware-independent.

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.

I don't think our company had a similar solution before RHEL, although that was back before I started with the company. The company started with RHEL because they wanted to have support.

Red Hat, as a company, is a big contributor to the open-source community. That's another one of the reasons that we want to use RHEL the product.

We used Sun Microsystems and Unix on on-prem. 

We have used SUSE Linux. We have also used open-source tools like Ubuntu, Fedora, and CentOS. We switched to Red Hat Enterprise Linux due to its vast exposure to security vulnerabilities. Its support model, subscription model, and its support for HANA are valuable.

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 product selection depends on the company. Telco companies have the budget, and they are using licensed products, whereas small companies usually use the free versions of Linux. They go for Oracle Linux, CentOS, etc.

We are using CentOS and Ubuntu on some of the machines. The company wanted to go for a free product, but I told them that for any support in the future, we need a licensed product, and they are now migrating to Red Hat Enterprise Linux.

We use Ubuntu and SUSE. We switched to Red Hat mainly for the enterprise support that we receive, the documentation, and the container integration.

We used Solaris before Red Hat Enterprise Linux. Solaris' environment is closed, while Red Hat Enterprise Linunx is open-source. 

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

We chose Red Hat Enterprise Linux because of its security. 

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

We are using Red Hat Enterprise Linux and Windows operating systems.

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

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.

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

No, we did not use a previous solution. We knew about Red Hat from our inception. It was a pretty well-known enterprise platform.

We used different solutions. We moved from AIX 7.1 to RHEL 6. Then we moved to 7. Now we're going to 8.

We chose Red Hat Enterprise Linux because we wanted to adopt newer technologies and we wanted to secure our systems. Red Hat Enterprise Linux was a good available option. 

We had a lot of different Linux distributions. The pros of Red Hat Enterprise Linux are that it's the same platform for everybody, and it works for everybody. If you need something very special, you might get issues in Red Hat Enterprise Linux, but you can work around it. 

The biggest issue with Red Hat Enterprise Linux is mostly the old packages. It is a con if you have something that you know is a bug that hasn't really been released in Red Hat Enterprise Linux but has been released in the other products.

I used to have Ubuntu, but I didn't like it. The beauty of RHEL is that you can easily find support, unlike Ubuntu. While Ubuntu has free subscriptions, unlike RHEL, you cannot get support for Ubuntu easily.

With Ubuntu, when I had an issue, I would have to go to Stack Overflow and check the internet. With RHEL, I like that I can go to IRC and post my question and they answer me.

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

I previously used CentOS, which is related to Red Hat. It was our client who decided to switch to Red Hat. I've also used Ubuntu which is an open-source solution with low security and therefore not suitable for enterprise-size organizations.  

We used to use JBoss at my previous company.

We previously used Solaris. We moved to Red Hat because it is easier to manage and more cost-effective. It is also easier to manage patches and security using Red Hat. 

We were using an earlier version of HP UX running on PA-RISC architecture, however we became concerned about the cost of remaining on the PA-RISC HP UX platform and possible future issues at virtualization.

My current company was using Solaris before. I was using Core Linux for three to four years. From Ubuntu, I shifted to RHEL and Solaris because I changed companies and jobs. We are using RHEL and Solaris in my current job, and I had to shift to these operating systems.

I have used the Ubuntu Linux base, I have used Kali-Linux and Debian. Of all those Linux systems, I think RHEL is much better, but I find Ubuntu much easier to use than RHEL.

Ubuntu is Debian-based, and Red Hat is, I think VM based. Another difference is open source systems have less support. Still, the community of Ubuntu is very strong and answers your query very promptly. But Red Hat is a certified, licensed product, and customer support from them is very good.

We previously used Windows and switched to Red Hat Enterprise Linux for flexibility and support.

We previously used Linux. Red Hat meets our needs more comprehensively.

I have used lots of flavors of Linux going back to 1995. Enterprise support was the reason Red Hat was selected.

I have also used Ubuntu and CentOS in different companies and for different clients. The utilization of packages, commands, and configuration files are different in Ubuntu. For example, if you want to restart a service, the commands are different in these solutions. They also have different firewalls. Red Hat uses firewalld and Ubuntu uses ufw.

We have many kinds of the linux version on the all environment but to HPC environment we use Redhat but all another versions work very well

No.
