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.

Positive

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.

I use Red Hat Enterprise Linux for running applications and databases on them.

It has a smaller footprint, so it uses less storage. The product is optimized for resource utilization. Patching is very streamlined for the operating system compared to Windows. We prefer using Red Hat Enterprise Linux over Windows whenever we can. Patching is much easier, and it seems more mature. When we apply a patch, we're less likely to have problems after. It's more stable.

All resources should be available on the website.

I have been using the solution for about three years.

I rate the support a nine or nine and a half out of ten. I am not rating support a ten out of ten because if we were able to receive all of the resources that we could from the website, then we wouldn't need to reach out and contact support. It's a learning curve.

Positive

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.

We're exploring more automation features. Three years is still relatively new for an operating system for our department. As we explore more automation-rich features and tools and subsets of tools, we'll be able to utilize the solution better. Red Hat Enterprise Linux may be very good at it, but our knowledge and experience are still growing. We need to take a deeper dive into implementing automation.

We use Red Hat Enterprise Linux with Microsoft Azure. We did not have concerns about using Red Hat Enterprise Linux in the cloud because we had spoken to other customers of Azure that had been running Red Hat Enterprise Linux. We can install Red Hat Enterprise Linux on our own, or we can use the custom-built Red Hat Enterprise Linux images available through Azure. It makes the deployment of a server much quicker and more efficient.

We have been migrating some workloads and applications from on-premise to Azure. However, we do not constantly move workloads back and forth between Azure. It's more of a one-way migration. We're trying to be less on-premise and more in the cloud. There's definitely a learning curve for the migration. There were some hiccups with learning how to do the migrations. We've done a handful of migrations so far, and each time, we learn from our previous experiences and mistakes. We use our lessons learned and have a better experience each time that we do a migration. It's getting smoother each time.

The knowledge base offered by the product is really good. There are a lot of resources available on the website. We have a direct contact for support, which we utilize on a regular basis. We have enterprise licenses, so we pay for support. We get support whenever we need it. I have been involved in Red Hat Enterprise Linux upgrades. It's pretty straightforward. We just convert from different Linux operating systems to Red Hat Enterprise Linux. My technical team has used Red Hat Insights, Image Builder, and Convert2RHEL.

We keep pretty close to the most current versions of Red Hat Enterprise Linux. There are many different versions of the product. Version 9 is the most current. We're trying to stay up with at least one or two versions close to the most current version to stay updated. We don't want to get to a version that would be at the end of its life.

The solution has helped us streamline and optimize our infrastructure for any applications or databases we run on a Linux operating system. They help us save on our physical resources because they're less demanding. Therefore, we don't have to spend as much money on a server that has a lot of CPU and a lot of memory. We can fit many more VMs on a single physical virtualization host because it's optimized. The support is great, and we can find quite a bit of information either directly through the Red Hat website or through the Red Hat community. We're able to do research on our own and find most of the information that we need. If we can't, support will assist us.

Overall, I rate the tool a ten out of ten.

We have Ansible deployed on our Red Hat Enterprise Linux servers. We use it to manage the security of our fleet of Ubuntu virtual machines.

Red Hat Enterprise Linux is way ahead of Ubuntu in terms of security and compliance. It is mainly the ecosystem of data science tools that our developers want that pushes us in that direction. As a security engineer, I have a lot more peace at night knowing that my Red Hat servers are doing a good job keeping our Ansible infrastructure safe because that has fingers into everything we do. It is pretty critical.

Red Hat Enterprise Linux has not affected our system's uptime in any particularly noticeable way.

Red Hat Enterprise Linux has not enabled us to achieve security standards certification because we do not have any yet. We will have them hopefully in the future.

There are some nice integrations with scanning for vulnerabilities. That is the feature I have enjoyed the most because I am a security person, and that is my bread and butter.

Ansible has certainly been a game-changer. It is a lot easier to keep a whole bunch of virtual machines consistent with each other and make a change consistently across all of them. We use them for data science activities. Our data scientists are constantly trying out new packages and downloading new tools. We have to enable them to have root access on their machines but also need to ensure that they are not doing anything stupid at the same time. There are competitors to Ansible, but we are a big Python shop, so it is a very comfortable environment for us.

The only issue we have had with it is around the SELinux configuration because the way Ansible installs, it sticks the platform passwords in a flat file. We want that locked down more strongly than what is there currently with SELinux. 

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

I would rate their support an eight out of ten.

Positive

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.

We use Red Hat Enterprise Linux in the cloud. We have Azure because it is the corporate standard. We do not have any concerns about using Red Hat Enterprise Linux in the cloud. Obviously, everything in the cloud is more exposed than everything on-prem, but it has got good, sensible, and secure defaults built in, so there are no concerns there.

In terms of Red Hat Enterprise Linux upgrades, when we upgraded Ansible this fall, that pushed us from Red Hat Enterprise Linux 7 to Red Hat Enterprise Linux 8. It should be a little easier from now on. Now that we have made the big jump from the older Ansible to AAP, we will probably be upgrading the systems on a quarterly basis.

We probably have not yet seen an ROI. We purchased it a couple of years ago, but we have not had the time to put it to as much use as we wanted to put it to. The cost is low, so it would not take very long to reach a return on investment.

We have not made use of the Committed Spend.

For its use case, I would rate Red Hat Enterprise Linux a ten out of ten.

We have a lot of Oracle databases, Tomcat, and Java microservices running on Red Hat Enterprise Linux.

A lot of our applications are like Java microservices. Deploying them on a Unix platform is so much easier. It's open-sourced and provides a lot of compatibility. It makes it easier for us to roll out applications. It is compatible with most Java microservices applications.

We like that Red Hat Enterprise Linux is a vendor-supported product. When we have problems, we just call Red Hat Enterprise Linux for support. The product employs a lot of automation tools to manage its OS. We love using Red Hat Satellite. We have close to 5000 servers. Managing individual servers would be a nightmare.

Red Hat Ansible Automation Platform and Red Hat Satellite help us automate our repetitive tasks. Every flavor of Linux distribution has its own specialties. The product offers a lot of integration within the Red Hat products suite. We use Red Hat products mostly, so it works for us.

The vendor keeps rolling out many packets, which complicates our job. We keep patching our servers. CVEs come out all the time. However, having a solid and secure OS will make our life much easier.

I have been using Red Hat Enterprise Linux since 2004.

I never had any problem with support. I didn't have any issues that I did not get a resolution for. Sometimes, it takes a little bit of time, but eventually, it gets resolved.

Positive

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.

I have seen an improvement in our deployment. When we have applications running on Windows, it takes longer to get them set up and provisioned, and the security is different compared to Red Hat.

The pricing could be better. The tool is getting expensive. Before, we could license only the hypervisor where Red Hat Enterprise Linux is running. Now, if a customer has a 12-node hypervisor, Red Hat Enterprise Linux forces customers to license all 12, even though they use only six.

We evaluated SUSE. At that time, SUSE did not have good support. We needed good support worldwide.

We use AWS and Microsoft Azure as our cloud providers. We don't use the off-the-shelf product that we get from the cloud. We build around it because we have a standard template. When we deploy our solution in the cloud, all the security features we need are already within the OS, as opposed to using the cloud OS and applying all the changes we need. It's easier to get our template to the cloud and use it.

The licensing for the cloud environment is totally different than the on-premise one. We use the Virtual Datacenter license on-premises. I don't see any difference because Red Hat Enterprise Linux still supports it, whether on-premise or on the cloud.

Red Hat Enterprise Linux knows its product. Whenever I have an issue, an engineer gets assigned to me. I can always escalate if needed. We're not using every host that we license. We ensure that we can fail over smoothly on every single hypervisor. It's fair to license them. We're not using it, but we're still paying for it. I do not like it, but it is a business cost.

We migrate workloads to the cloud. I never upgrade an OS. I usually replace the old OS with a new OS and migrate the application. I use the OS versions 7, 8, and 9. The migration is pretty straightforward. AWS and Azure have a tool that we can use to integrate with our environment. It's a lift and shift. We grab the VM from our on-premise hypervisors and move it to the cloud.

We use Red Hat Ansible Automation Platform mostly for patching and upgrading to the next revisions. We don't upgrade from one OS to another. We build on a new OS and get all the applications running there. Once the application is running, we move all the workload from the old OS to the new OS. There's no impact on the existing system.

I don't do the day-to-day patching because we have a managed service. However, it does create interruption. When we do a patch, we have to reboot, especially when there's a kernel update. It causes an outage. I have used Red Hat Insights. It gives us insight into what's happening on every single Red Hat VM that we have. It tells us if it's behind or has some performance bottlenecks. It gives us visibility on the health of the whole OS.

People who are looking into the product must get a good account manager. We must have a good account manager who we can always contact and who gives us all the updates that we need. They keep us in the loop on what is happening in the Red Hat world. We are satisfied with the product.

Overall, I rate the tool a ten out of ten.

We use Red Hat Enterprise Linux to run quite a few pieces of software. It's mostly for jPOS, but we also run some Apache solutions and some security applications.

Red Hat Enterprise Linux has streamlined a lot of the support issues. When we've had problems, Red Hat has been proactive about solving the problem with us. Support is always an issue with open-source platforms. By providing this support, Red Hat makes it much easier to adopt Linux.  

I love Red Hat Enterprise Linux's built-in security. You can see who is trying to do what and who isn't allowed. You get an alert for that. We also use a product from Symantec on the Linux system for real-time threat detection, but I think we probably don't need that. Red Hat already has these capabilities, but the security team needs something they can centrally manage. They need to know whether the system is protected and the agent is running. 

We use it on VMware, and we have a multi-site deployment, so it's very easy to patch and keep the servers up. We use Ansible automation for patching, which has really helped with the service uptime.

I like the speed of the OS data and the ease of Ansible automation. I don't need to spend much time managing everything. The provisioning and patching using Ansible is seamless. Ansible automation gives you almost a cloud-like capability on-premise. Most of my group doesn't have cloud skills. I learned it on my own and got my Kubernetes certification. I'm familiar with the automation infrastructure, how to build the execution environment and implement the private automation hub. Others still need training.

I've used Red Hat Enterprise Linux Image Builder for testing and development, but I haven't put it into production. We have a VMware template, and we've been doing training on VMware, but we are not there yet. I think they might move from VMware to another product. They are looking at other options, such as OpenShift, but we don't have training for OpenShift yet. They should try to have a salesman come and get OpenShift training for customers. If they make training free for the customers, more would switch to OpenShift from VMware.

I use Linux on Satellite with Ansible infrastructure. It would be great if there were a universal interface to control Red Hat Enterprise Linux's policy from Satellite. It could be a dashboard showing which policies were enabled on what system and allow you to apply them from the dashboard. 

I think Red Hat training could be cheaper. A company can move fast technologically with enough training. They will be stagnant without training and remain unable to fully leverage the technology. I have been encouraging the group to get a subscription to the training course for five years, but we haven't been able to take advantage of it because of the cost. They should make it cheaper for clients and offer big discounts at scale. 

When people lacked training for the technology we use, we migrated away from it. I worry that if we don't have enough training available to the client, they will eventually migrate away from Red Hat. More affordable training on key technologies like Satellite and Ansible automation will help us retain customers on those products. Downstream it will help them migrate to the latest and greatest Red Hat Enterprise Linux, as well. 

I have used Red Hat Enterprise Linux since 2005.

I rate Red Hat support 10 out of 10. I've been very impressed with the knowledge base and the support from Red Hat. When I create a ticket, they respond and resolve the issue quickly or they point us to the correct resources. For example, we had an NFS issue with ISO, so they helped us with the mounting options. We also had an issue with IBM AIX and Red Hat integration. Red Hat referred us to the IBM support stack, and we were able to get IBM to help us out.

Positive

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. 

The deployment is straightforward because we use Ansible automation to spin up a new system and install applications directly from the Ansible workflow. We were planning to have Red Hat Enterprise Linux 8 online last year, but Red Hat Enterprise Linux 9 came out, so we decided to wait for a bit, and we're almost ready to upgrade to Red Hat Enterprise Linux 9.  The application folks still haven't had enough time and money to migrate everything over, and we need a project manager. 

I rate Red Hat Enterprise Linux 10 out of 10. It comes with all of these nice tools like the Satellite automation web console. 

We use it for databases and applications. In the new model, we keep databases separate from applications. Currently, about 90% of our operations are running in Red Hat 8. Some systems are still on Red Hat 7, but those will be migrated off by the beginning of next year.

It's been great since we have it. It's been reliable and fast. We keep all the security agents, and we've been taken care of right away, and that's the improvement in our company. It's with the new RHEL. There's always something new, something good that works for us. 

Moreover, we might need to move workloads from the cloud in the US to China in the future.

As we're migrating and doing the Elite upgrade, which is an in-place upgrade, we find it great. We use it for databases, and we're testing it for applications. Some applications don't work, but some are functioning well. So far, it's been a positive experience.

Since I'm more focused on migrating, Leapp is awesome. We are able to do something that will work the way it's working.  There are no issues or breaks.

RHEL's knowledge base is great. It's very good. Especially when you try to open a case, it gives you all the options you need, so you don't have to wait for the case to be opened. You can get all the information you need right there.

Moreover, I am in the process of testing Leapp and Red Hat Insights. And then create our images from there rather than create MIs.

At the new company, we've been using it for three years. At my previous company,  we used it for over five years. Personally, I have been using it for almost eight to ten years.

We often have to go through people who have the same labels as us and who have the same knowledge base articles as us, which takes time. But they do it first; it's searching the knowledge way that I search. That I can do. That takes the time before. They do the payment. They sent me exactly what I had already found. And then we can go to the next level. That is taking a little bit more time that we can be a little bit better. So, the initial step of the support process could be improved. 

90% of people who open those bases are administrators who already look on the Internet for all these knowledge bases. So by the time we get there, we're gonna get the knowledge base back. And that's not helpful. 

Positive

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. 

The initial setup wasn't complex, but since we wanted to make it easier to use, it became harder to make it work the way we wanted. Not out of the box, so we can just build a server that is ready to be deployed right away without any more interventions.

We use RHEL with AWS because it's easier for us to maintain since we create our own AMIs and we update that as we need it. So we don't need to follow their schedule until we get it more secure and more reliable for us.

Overall, I would rate the solution a ten out of ten. 

We had a lot of IBM AIX servers. We migrated a lot of them to Red Hat Enterprise Linux. We have a lot of VMs, and we have a few physical servers. Currently, we are moving all the Red Hat VMs to the cloud. There are 1,600 to 1,700 Red Hat VMs that we are currently running.

The main benefit is that it can be easily recovered and easily restored. It is on the VM. We can easily restore every image that we back up on the VM. If something happens, we can easily fix it. Support and maintenance are easy. The most common issues that happen with Red Hat Enterprise Linux are password restore issues. We can go and restore the passwords through the single-user mode. This feature is well-developed and good.

We are using Ansible for the most automations. We can push everything through Ansible. We are moving towards automation to make sure our system can be easily maintained, and we can recover, restore, and do the things that we want. We have 1,600 to 1,700 servers. We have Ansible Tower, and we have a few satellite servers and a lot of capsules to support Red Hat servers.

If anything is supported by Red Hat Enterprise Linux and the feature is available in Red Hat Satellite, we are able to install it on Red Hat Enterprise Linux. We are using Red Hat Satellite to install all the patches and all the packages, so if a feature is available, we can easily install it if it is supported.

Red Hat Enterprise Linux has built-in security features for simplifying risk reduction and maintaining compliance. We are working with most of the security environments. Security is our main concern. We have zero tolerance when it comes to security. We are able to apply security rules and regulations within the Red Hat environment.

We are using Red Hat Enterprise Linux 7, and we normally look at how it can easily support the system. With Red Hat Enterprise Linux 7, we have a high-security system. We have a lot of features there. That is the main thing, but currently, we are moving from Red Hat Enterprise Linux 7 to Red Hat Enterprise Linux 8. 

Red Hat Enterprise Linux Leapp and Red Hat Insights have been useful. RHEL Web Console is also helpful.

We have access to the Red Hat knowledge base. We have frequent meetings with Red Hat. Red Hat partners provided us with all the information and any kind of training.

We are using the features that are available with Red Hat Enterprise Linux and Ansible. As such, there are no specific features that we are looking for. 

We have frequent meetings with them. We have had some issues on the application side and the OS side for which we opened cases and discussed those concerns and questions in the meetings offered by Red Hat.

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

Upgrades and migrations are ongoing processes to stay current. We are a big company. We always have migration going on. We always have the build process. Red Hat's presence keeps increasing in our environment. We are going to have about 2,500 Red Hat Enterprise Linux VMs in the next year.

If there are any concerns, we have a meeting with Red Hat, and they provide the required support. When we have any concerns or questions, they answer them. It is easy. I would rate their support a nine out of ten.

Positive

We have probably seen an ROI. Red Hat is getting better every day. 

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

My use cases are mainly limited to databases. I'm also involved in other ETL tools; I worked on migrations from older vendors, like Windows, and transitioning to RedHat Linux.

The most valuable features are security, performance tuning, storage management, and OS-level automation. If you wanted to automate while adapting with different vendor scripts or your own development because it's Linux, it's not like an operating system itself. It is always going to perform how you expect it to. IAQt's not like other operating systems. It is based on Linux. 

These are the main features. Storage management is another valuable feature that is very critical in an operating system. It works along hardware and software.

Compared to other OS', Red Hat Enterprise Linux is the best from my 20-plus years of experience. It is well-suited for production environments. In 2003 and 2006 I worked with one of the vendors in another country. We were able to run a database instance on Red Hat Enterprise Linux for two years without restarting it. The database was located in a remote location, and the team could not be on-site to provide support. We installed it ourselves and it worked for two years. We restarted the database instance. We didn't need to touch it internally. It works like a charm.

If it works, it works. You don't need to attach anything at all. You just monitor them remotely. Nobody was there on-site. That's the beauty of it. Red Hat Enterprise Linux is great. I love it.

The GUI has room for improvement. It needs to be managed by many administrators. It has basic command lines. They could improve it with better automation. We'd like to be able to create a script, and then have the ability to deploy it where we don't need to write everything manually. That part can be useful for automating. 

We'd like it so that a coder wouldn't need to go through it, read it, go to GUI, and then generate a script. If they want to modify it, they could modify it. If Red Hat Enterprise Linux is going to build something, the REST API can be helpful instead of writing their own, starting from scratch. That would make it easier.

For future releases, there could be more integration. Regarding security, we used a different tool for scanning, but having a tool within Red Hat could enhance it. 

Support is essential for open-source software. If they improve aspects like prevention against hacking, it would be beneficial. 

Before, with a surge in hacking incidents, companies lost data, and once lost, it remains lost forever. You never know when it might be used. Improving security, especially in terms of prevention, is crucial. I would like to see ongoing improvement in this aspect.

I've worked with different companies. In my over 20 years of experience, in the last five or six companies I've worked for, all of them have been using Red Hat. They use it mostly for databases. 

I'm in the database sector, primarily working as a senior technical architect. End-to-end, we always find that Red Hat is best suited for Linux, especially for Oracle and other NoSQL databases. It's reliable, first and foremost, and it offers stability and performance. Performance tuning is crucial, and once it's set up, you can rely on it. 

With the cloud, it's moving into containerization, and most of them support the cloud. 

The customer service and support are really good. 

Positive

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 have seen a return on investment. 

As a consultant, I handle sizing, design, and optimization for new infrastructures and I would recommend Red Hat Enterprise Linux to anybody considering it.  

Overall, I would rate the solution a ten out of ten.

My organization has different departments. In my department, we mostly work with containerization. I am using Red Hat Enterprise Linux as a part of OpenShift. I use the basic package and base image of Red Hat Enterprise Linux.

For scale-up in our platform, we use CoreOS as the master, and for the workers, we use the Red Hat Enterprise Linux service. From OpenShift version 4.10 onwards, we cannot use Red Hat Enterprise Linux 7 worker nodes. We were using Red Hat Enterprise Linux 7 worker nodes, so we upgraded to Red Hat Enterprise Linux 8. 

For OpenShift, there are some recommendations from Red Hat in terms of what needs to be used for the control plane and what needs to be used for the worker nodes. When you are using CoreOS and Red Hat Enterprise Linux worker nodes, there are some difficulties in managing them. For example, when you upgrade OpenShift, you need to upgrade two times. The control plane is upgraded separately because it uses CoreOS. The control plane has a lot of certificate updates that will in turn be updated on the worker nodes, so you have one restart of all worker nodes, and then when you need to upgrade your worker nodes, there will be one more restart. 

Overall, you have two reboots in your production environment, which is an issue, but it is related to your choice of product in your environment. We have this issue because we opted to use Red Hat Enterprise Linux 7 or Red Hat Enterprise Linux 8 worker machines, whereas Red Hat recommends using CoreOS because it is pretty fast in terms of rebooting and functionality. When you upgrade the control plane, that itself will update the worker nodes, so you are done in one shot. When you need to upgrade your Red Hat Enterprise Linux machines, you need to use the Ansible Playbook. You can then upgrade to Red Hat Enterprise Linux 7, 8, or any other version. Regardless of the versions, you can upgrade the operating system and the OpenShift version. For this purpose and for some ad-hoc activities, we are using Ansible Playbooks.

For us, its security, management, stability, and hardening are most valuable. All of these features are better in Red Hat Enterprise Linux as compared to Microsoft Windows.

Red Hat Enterprise Linux is very good in terms of risk assessment. It is also good for maintaining compliance. It is better than Microsoft Windows.

From the administration perspective, I do not have any issues with Red Hat Enterprise Linux. For me, it is more convenient than Microsoft Windows.

My organization has been using Red Hat Enterprise Linux for a long time. They have been using it before I joined the organization.

It is pretty good in terms of stability. It is a stable product. I would rate it a nine out of ten in terms of stability because sometimes the packages can have bugs.

Its scalability is good. I would rate it a nine out of ten in terms of scalability.

We never encountered any issues while using OpenShift.

I have mostly been working with Red Hat Enterprise Linux. 

I have been involved in the deployment of OpenShift. It is pretty straightforward. We just need to get the licensing, and we just need to create a pool for our containers session in Red Hat Satellite. We can do the configuration from there. It does not take long because we are adding the nodes to OpenShift. During the scale-up process, we only need to subscribe to the nodes with the Red Hat subscription. It does not take much time. If we have a good spec, the scale-up would not take much time. It would take less than twenty minutes. It is pretty fast.

In terms of maintenance, when we have the bug report, we need to do the security assessments. Over time, there might be some bugs related to some packages. At that time, if it is critical, we will be scheduling a maintenance activity on our platform. 

Red Hat provides high availability from the application perspective. You get high availability when you are using OpenShift, so when you are doing a maintenance activity on the OpenShift side, there would not be any downtime. The high availability is very good. For the end-users, there would not be any application outages if you configure your application with proper replicas. They would not even realize that there is a maintenance activity happening to the underlying workers.

It was implemented in-house.

We did not evaluate other solutions. Red Hat Enterprise Linux is the choice of most of the companies.

If you want to integrate with OpenShift or build an OpenShift cluster with the master Red Hat Enterprise Linux and worker Red Hat Enterprise Linux, you can do that, but you need to plan your upgrade or maintenance activities. It would be better if you choose CoreOS for both. CoreOS would be a better choice in terms of maintenance activities or upgrade activities in the future. If you cannot afford that, you can go with the Red Hat Enterprise Linux operating system, but you need to do two upgrades. You first need to upgrade the control plane and then you need to separately update your worker nodes. That is the only thing you need to keep in mind.

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

We use Red Hat Enterprise Linux mostly for development.

We use Red Hat Enterprise Linux with Git apps in our closed environment to develop and run scenarios.

Red Hat Enterprise Linux's documentation could be improved. Sometimes when you call up support to have that Red Hat answer, they send you back a Reddit or Google link. I can Google or go to Reddit, but I want an answer from Red Hat.

I have been using Red Hat Enterprise Linux since it started back in the 1980s.

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

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

I rarely call Red Hat Enterprise Linux's support, but when I do, they send me a Google link.

Neutral

Since I've been deploying Red Hat Enterprise Linux for so long, it's not complex for me. Once we configure our kick start, we power up a new system, attach it, and it builds it.

We implemented Red Hat Enterprise Linux directly through Red Hat.

We have seen a return on investment with Red Hat Enterprise Linux concerning the ability to develop what we need, what we do, and our scenarios. The solution saves us man-hours, and man-hours equals money.

We cannot use Red Hat Enterprise Linux on the cloud because I work as a contractor for the government, and all our development is in a classified area where we can't touch the internet at all.

In the last quarter, Red Hat Enterprise Linux products like Satellite Server and OpenShift stood out because of their ease of administration. I do system administration. When my customers need something, assisting them with these products is easier than giving a long configuration of YAML.

I like Red Hat Enterprise Linux's built-in security features. We use their SCAP features when we do our kickstart and build it.

We were using Docker, and the Docker swarm was trying to get all the containment. We're now switching to Podman and getting our developers to learn that more so we can give them the ability to kick off containers.

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