Red Hat Enterprise Linux (RHEL) Reviews

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

We've implemented OpenShift on top of OpenStack. It's a Red Hat OpenStack environment, which is the virtualization layer, and then OpenShift is for the cloud technologies.

It's currently on-prem on a private cloud. In the future, we might utilize a public cloud if the government approves that. Currently, the banking industry isn't allowed to go to the public cloud.

There is a big move towards digital banking. They prefer to have their solution up and running as soon as possible when the request comes in. They have to have the libraries and all the containers up and running. In a couple of minutes or seconds, they have their whole infrastructure up and running.

With regard to security, most companies are moving towards the black box approach and Red Hat. It's much more secure compared to the other vendors.

There's consistency, and it's resilient as well.

With regards to OpenShift, everything is related to cost. If you need a vanilla OS, you have to spend a lot on the licensing that is tagged. You have to spend on the infrastructure and the licensing on a core basis, and whatever is required on your containers, you just have to give minimum hardware specs.

Red Hat Enterprise Virtualization isn't up to the mark as compared to VMware and Hyper-V, but they're moving everything on OpenShift for containers and virtual machines, which is stable. If you go into the virtualization layer, they still need to improve a lot of things, but with regards to OpenShift, containers, Docker, and other things, they are doing well. 

We've been using it for three to four years.

Compared to Windows and other operating systems that I've used, it's stable. 

I'd rate it a nine out of ten in terms of scalability. We have plans to increase its usage in the future. Our infrastructure will be able to scale. We have a plan to grow it every three years.

Their support is very good. Most of the things are already listed in their knowledge base. Support cases are only raised when you end up with any critical situation. I'd rate their support a nine out of ten.

Positive

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.

It was very straightforward. When we did the proof of concept, we had everything ready within two or three days, and then the engineers who came to deploy it did it in a day's time once we had all the infrastructure up and running. This was just for the proof of concept.

With regard to the implementation, they had a timeline, and they did deliver before the timeline.

It has been deployed on Nutanix as well. They are present even in the marketplace for AWS. It's a straightforward installation. They have two categories: UPI and IPI, and the installations are very straightforward, but it requires a lot of expertise if you want to deploy it on a public cloud.

It was implemented by Red Hat. In terms of maintenance, it does require maintenance, but once it is highly available, it's easily done.

We've seen an ROI. It has had cost benefits. 

It has saved us money. We did a proof of concept with the VMware Cloud Foundation and OpenShift. We saw the feasibility and how fast it can be deployed. There were a lot of considerations. We evaluated it from all perspectives. Compared to the VMware Cloud Foundation, we noted that it was just 50% of the cost. If you go for VMware, they charge you on a core basis, and the licensing costs are huge. You'll have to spend on Microsoft licensing, and then you'll have to spend on the OS as well. Comparatively, it's much cheaper.

We purchased it directly from Red Hat. Compared to open source, it's very pricey, but you get the support, which makes it much better.

You have to deploy it and evaluate it. You can see that there's a lot of difference compared to other operating systems. It also depends on where exactly you're going. There are mainframes and other different places where you can deploy it. Even on the mainframe, it makes a lot of difference.

With Red Hat, there are a couple of things you need to consider while building your infrastructure. You need to have good hardware, and you need to have a compatibility matrix to be able to have a stable environment. It has to be tested in a proper way, rather than deploying it on any box.

In terms of the golden images created by the image builder tool, we have vendors who come with their solutions. They come with the containers, and they deploy them. Most of them are using GitHub, and we just provide the infrastructure. From a technical perspective, there's a solutions department that's into APIs. They handle everything, and we just provide the infrastructure.

Overall, I'd rate it an eight out of ten. 

We are running databases and applications on it. We are also using the Squid proxy server, NGINX, and Apache, so we are running multiple services on the servers.

We are using Red Hat Enterprise Linux eight and nine. We also use Red Hat Satellite and Red Hat Ansible Tower.

I've mostly worked with the telcos and banking sectors, and they mostly have on-prem setups. We do have a hybrid environment where we have multiple machines running on AWS. I am based in Saudi, where they are using another cloud called Din. They are running Red Hat Enterprise Linux on Din as well.

Their trainings should be free.

It's more stable than the other operating systems. That's why everyone is using the Red Hat Enterprise Linux platform instead of Windows on the server side.

They regularly send us updates regarding patches and security vulnerabilities. We patch our servers quarterly. Mostly, we do patching every three months. They always send us updates on our official email, so it's quite good.

It would be very good if we can easily migrate from CentOS to Red Hat. We are about to move from CentOS to Red Hat. It would be great if they can give us a free version. Otherwise, we need to purchase licenses, which are quite expensive.

I've been using Red Hat Enterprise Linux for five to six years. I have only been working with Red Hat Enterprise Linux over these years.

Its stability is quite good. I'd rate it a nine out of ten.

I'd rate it a nine out of ten in terms of scalability. It's being used in the banking center, and they are running their applications and databases on it. 

We have LVM configurations, so according to the application, we can increase the disk size. The environment is quite good for my use.

Their support is quite good, and they're responsive, but they first send us to the platform to check the issues. They don't provide direct support immediately. For a new engineer, it can be quite difficult. It would be good if they put us directly on the call in case of an emergency.

Some of the newer engineers require support in a quick manner. Those of us who have experience of six to seven years don't require the support, but in the beginning, we required support, and their support was quite good.

Positive

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.

It's best in terms of security features. We configure the templates and then we implement the CIS controls, security features, and complete patching of the server.

In terms of maintenance, Red Hat provides us with the details about the security vulnerabilities, and the engineer needs to implement all the security on the servers.

We did it on our own.

We haven't seen an ROI.

From a management point of view, it's quite good, but everyone is complaining that it's more expensive than the other operating systems.

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

We run various application servers. We have application servers for Java and Python. We also run Postgres and different applications. We have Kubernetes, Docker, Docker Swarm, etc. We have a wide variety. 

We weren't trying to solve a particular problem by implementing Red Hat Enterprise Linux. We've used Red Hat Enterprise Linux for so long. We used to modify the Kernel in the early versions of Red Hat, but that's not needed anymore. We are currently using versions 7, 8, and 9. 

Red Hat Enterprise Linux has enabled us to centralize development in our hybrid cloud environment because the containers can be migrated from Red Hat Enterprise Linux to AWS. It's not an issue. There is also a Red Hat-supported programming tool called Skupper, which is a layer seven service. It's an open source product. It's supported by Red Hat, so we could use that to migrate our containers back and forth on the cloud and on-prem, which is very much needed.

Red Hat is pretty good at containing risks. We have a firewall, but we also use iptables and SELinux. SELinux has proved to be very valuable. We have certain tools where when somebody tries to break SELinux, we immediately get alerts.

We don't have a problem with compliance. We also use Red Hat Satellite. Our Red Hat Satellite server is helpful in terms of meeting compliance requirements.

We're able to modify and migrate containers and redeploy containers very easily. We do that on the Red Hat platform. We do it with other tools such as VMware. Red Hat API works very well with other vendors, so that's definitely a plus. In terms of changes, for instance, if we want to connect to ServiceNow to create a ticket in Ansible, we're able to do that without any problems whatsoever. We can create a ticket in ServiceNow. We can remediate it, and we can close the ticket on ServiceNow from Ansible. Ansible is a big part of Red Hat.

It's a rock-solid operating system. We don't need anything fancy from the operating system itself. What we need is something that doesn't crash, stays up to date, and provides the security features that we need to keep external players out.

The CVEs that come out for the vulnerabilities are very fast. We try to do patching in different tiers. Our regular patching happens once every ninety days, and then we have special iterations that need to be done, and those are on demand, or if there's a high-security risk and it's absolutely immediate.

The other thing that we like about Red Hat is the support for open source. That for us is a slam dunk.

They should work more on container documentation. The only issue that we have is that Red Hat specifically promotes OpenStack, and we don't use OpenStack. It's good if you're using OpenStack, but if you're not using OpenStack, and you're using Docker or something else, it isn't that good. Having more support for non-OpenStack would be very helpful, but, of course, as part of their business, we don't expect it.

I've been working with Red Hat Enterprise Linux for many years.

It's very stable.

It scales very well. We have about a thousand servers, but we could scale to five thousand servers without a problem.

Their support is good overall. It's better than some of the other vendors. The staff is very friendly. The people I've met hear and discuss issues. We're very much interested in open source, so we use a lot of open source. The engineers have been extremely helpful. 

I'd rate them an eight out of ten. I'm not giving them a ten. Some of it has to do with the time cycle, and some of it has to do with different levels of quality with the support. You could get a junior support person, and obviously, that's going to be a very different experience.

The knowledge base offered by Red Hat is very good.

Positive

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.

We use certain tools from HashiCorp, such as Packer, so deploying it is very simple. We have a script that runs every night, and it creates via the CI, goes up to GitLab, gets whatever it needs, such as parameters, and sends it to Packer. Packer grabs the ISO, and it creates a very specific, customized deployment. It's done with a couple of right clicks. That's it.

We've absolutely seen an ROI. It's in terms of reliability, stability, security, and usability. You name it. The use cases are out there.

The licensing structure is very convoluted. It's very confusing. We have a Satellite server, and we license it through the Satellite server, but if we didn't, we'd have to buy individual Red Hat licenses. That would be a nightmare to maintain in terms of renewing it every year and things like that. 

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

I work in the energy sector, so we use Red Hat Enterprise Linux for a variety of purposes. These include high-performance computing, running applications like SAP, geospatial applications, and Oracle. We rely on Red Hat Enterprise Linux for a wide range of applications, including those that require running Oracle databases.

It is important to our organization to have a solution that avoids cloud vendor lock-in. We just don't want to be locked into just one side or the other. We want to have the flexibility and availability to explore other options.

One of the main reasons we chose Red Hat Enterprise Linux was its reliability and stability. Compared to the Microsoft Windows environment, the Linux environment provided much greater stability. Therefore, we decided to use Red Hat Enterprise Linux for all our critical applications at that time, as they required a Linux-only environment.

We use Red Hat Image Builder as well. The golden images created by Image Builder are okay. In our organization, we prefer to create our own images because we need to incorporate our own security measures and harden the images accordingly.

Red Hat Enterprise Linux could do better in live patching. In this day and age, vulnerabilities are constantly emerging, I feel that Red Hat Enterprise Linux has fallen backward in terms of live patching, particularly live kernel patching. There are other products available that can perform this function, and they often follow their direction. 

Currently, my company has a live patch solution where we can patch the kernel without rebooting. This is essential because certain applications cannot tolerate downtime for reboots. However, there is a security concern when the patching process is delayed, as it exposes the system to high vulnerabilities and risks. So, when critical applications go down due to rebooting, it has a significant impact on both the financial and operational aspects. It requires a lot of money and manpower to schedule and execute the reboots, and during that time, the application downtime results in losing money. I believe this is an area that Red Hat Enterprise Linux should focus on to address this challenge.

I have been using the Red Hat Enterprise Linux operating system for around 20 years. We transferred our existing subscriptions to the cloud version. We are actually exploring hybrid solutions and availability options. As we transition to Azure, we are bringing our own subscription.

The scalability is good. We are able to scale efficiently. In our high-performance computing department, they handle a lot of scaling, and it's going well. Red Hat Enterprise Linux scales well.

I'm not particularly fond of the support. For example, when we have a server that's down, we raise a ticket indicating the severity of the issue. Then we receive another email suggesting things we can try to resolve the problem. I miss the days when we could directly speak to someone because sometimes, depending on the maintenance contracts and SLAs, it can take a lot of time without actually making any progress. Whereas speaking with a support representative could significantly reduce the downtime. So, I'm not really crazy about it.

The knowledge base is good. I would rate it a nine out of ten. 

Neutral

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.

Personally, I find the deployment process straightforward, but I've been doing it for quite some time. I can't speak for someone who is new to it. However, from my experience, it's relatively straightforward. I've been in this role for a while, so I'm familiar with the process.

Currently, we use Azure AVS, which allows us to migrate existing physical machines to the cloud until we can fully modernize them. It's much easier than it was a couple of years ago, but there is still some work to be done. Overall, it's manageable for us to move workloads between the cloud and on-premises or data center environment using Red Hat Enterprise Linux.

We have streamlined our deployment process within our guidelines. I can build a server in just three minutes. The time required depends on the type of server we need. If it's a more specialized server, it may take longer. However, it's nothing like the old days when it used to take several days. Especially in the cloud environment, it's quite fast. On-premises is a different story because we need to consider hardware availability, which can take longer. But once we have the hardware, the deployment itself typically takes less than an hour, especially when we leverage tools like Satellite for automation.

We have indeed realized a return on our investment. If we hadn't, we wouldn't still be using Red Hat Enterprise Linux. However, we are always striving to improve our return on investment. That's why we continually conduct due diligence and explore other operating systems to ensure that we're not blindly sticking with a particular company. We want to find the best solution that can potentially save us more money while delivering an equal or better return on investment.

Red Hat Enterprise Linux is starting to realize some other companies are gaining some footing in the industry. Red Hat's pricing still needs to get a little bit better. When you look at what you pay for a subscription compared to what you can pay with some of these other companies that do offer a lot of technical backing behind them, it starts turning heads.

Red Hat should focus on making enhancements and providing better support in that arena.

Before choosing Red Hat Enterprise Linux, we did evaluate other Linux-based solutions. When we initially chose Red Hat Enterprise Linux, we had options like Solaris and SGI. However, even recently, we have continued to evaluate other distributions because the Linux landscape is constantly evolving. There are new solutions emerging, so we have to perform our due diligence and assess what they can offer.

For customers looking for alternatives to Red Hat Enterprise Linux, my advice would be to choose something that aligns with your requirements and that you are happy with. Don't just pick something because it's cheap. You gotta look at the long term. Also, know what is needed for your project. For example, if you have issues, can you get those issues resolved in a timely manner? If you run into an issue, you're stuck, and they can't help you out, this means your project will be delayed. You will need to weigh that out.

Primarily, we use it for a couple of different servers. Some are doing data hosting, and some are doing network management-type functions.

We use it on-premises. We do not use it on the cloud. Because of government work, we're not cloud-based.

By implementing Red Hat Enterprise Linux, we were mainly looking for stability. By having a lot of open source solutions, we ran into problems where there were too many flavors and too many variables. We ran into issues with ISO and other things where this particular site was a one-off from this site, which was a one-off from this site, which was one-off from this site. That became a problem for making sure that we stick to a consistent level and patch to a consistent level across the board.

The portability of applications and containers built on Red Hat Enterprise Linux has been good. We do a lot of containerization and a lot of microservices. It has worked really well. It helped in keeping our organization agile. Our partners provided us with a lot of quick utilities and reuse of things. We can shut down a container and spin up a new container to introduce new capability quicker. 

The biggest feature that I have found valuable is stability. 

The way it lent itself to automation has been very invaluable for us. It makes the setups a lot more consistent and repeatable across the board. We're able to deploy the product quickly in a very consistent manner, which meets our timelines. A lot of what we do has very short spending dates, and they need a lot of product work.

It has been pretty good for us. I have no complaints as such. We just learned that we can get access to more support documents by going through the portal. I didn't know that. If it was something that was more known or advertised, that would have helped us to find out some of the information a little better.

I have been using Red Hat Enterprise Linux for about a couple of years.

It's a 10 out of 10 in terms of stability.

It's a 10 out of 10 in terms of scalability.

The customer service is good. There is a lot of support documentation out there for anything you're looking for.

Positive

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.

It was very straightforward. We've pushed in further to make our own ISOs, so we're making sure that everything is getting the same applications and everything is deployed across the board, and we are able to virtualize in some cases. It has been good.

You definitely get what you're paying for. From what we've seen, it has been great. It has also allowed virtualization and making their own ISOs. We're able to package all that up, and it has worked consistently and repeatability. We've written our own Bash scripts so that we can automatically deploy that and stick it as part of the build. We're saving a lot of time and getting to a common platform repeatedly.

Overall, I'd rate it a nine out of 10. There's always room for a little bit of improvement.

We use Red Hat Ansible Automation Platform. We are using version 8.4, but we started with 8.3.

The solution’s stability is its most valuable feature. It has only been two years since I first started using the product. So far, I have seen a subtle comparison of the solution’s stability to other operating systems.

It is challenging to use the knowledge base and the deployment documentation. Some of it is all over the place, and it's challenging to piece them together.

It has been two years since we put in the first footprint of Red Hat Enterprise Linux in our organization.

We have about 30 to 40 servers.

The support team is pretty good. Whenever I send support requests and ask questions, the team is knowledgeable enough to get me the necessary answers. Sometimes there are delays in the response. However, it has been a positive experience for me.

Positive

I was the main engineer during the initial deployment of the product. The initial setup was straightforward. Whatever was in the documentation was exactly what was meant to be done.

We did not struggle with the documentation because I have been an engineer for years. Someone who is just getting started might have a different perspective on the ease of setup.

We purchased the solution from a third-party vendor.

I use Ansible Builder to build my containers. However, I do not use Red Hat Enterprise Linux’s image builder tool.

We do not use Red Hat Insights yet, but we're planning to use it in the near future. As soon as we get more servers in our environment, our firm’s directors might decide to start using Red Hat Insights. Right now, we are just using Automation Analytics. The solution’s resiliency is pretty solid.

We implemented the solution because we wanted automation. We cannot install Ansible Automation Platform in operating systems other than Red Hat Enterprise Linux.

Overall, I rate the product an eight out of ten.

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

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

The solution should improve its documentation.

I have been using the solution for 16 years.

The solution scales well.

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

Positive

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

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

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

I work in the financial industry in Brazil and my first job was to use Linux.

We deploy Red Hat Enterprise Linux on-prem and in the cloud. Our cloud provider is AWS. 

We use Red Hat Enterprise Linux for web applications, including the JBoss data bridge. We also have some applications for prevention and risk. Red Hat Enterprise Linux is used for most of our applications in Brazil, so it is used for almost everything.

We run our workloads and applications on AWS.

There are many Linux-based operating systems. We wanted an operating system that was mature and reliable, and Red Hat Enterprise Linux was the best choice for us.

Red Hat Enterprise Linux is a highly resilient operating system. It has a strong XFS file system, kernel, and package build.

Migrating workloads between the cloud and our data center is easy. There are no problems.

The knowledge base offered by Red Hat Enterprise Linux helps a lot. It is very useful and has helped me to resolve the issue by looking at the documentation.

The integrity of our operational systems is very stable. Red Hat Enterprise Linux has a good file system type and good kernels. It does not crash for any reason. This makes it a very stable platform for me. It is the best solution for our needs.

There was a reduction in the amount of detail provided in backlog messages between Red Hat Enterprise Linux versions six and seven, compared to versions eight and nine. This makes it more difficult to troubleshoot errors in versions eight and nine, as users must dig deeper into the operating system to find the source of the problem. Versions six and seven provided more detailed error messages, which made it easier to identify and fix problems. Deploying applications using Red Hat Enterprise Linux versions six and seven was seamless. However, there is a chance that something could be broken when deploying with versions eight and nine, and we may not know it.

I have been using Red Hat Enterprise Linux since versions four and five.

Red Hat Enterprise Linux is extremely stable.

One of the reasons we adopted the Red Hat Enterprise Linux ecosystem is because of its ability to scale.

I have not had a good experience with Red Hat engineers. When we have an issue, it is very difficult to have it resolved in the first call. They always have to escalate the issue and involve multiple people. At a minimum, we have to escalate an issue three or four times before it is resolved. The support team in Brazil has helped me a lot because they work with me to resolve the problem, but if I have to open a ticket and follow the steps I never get proper service.

I give the technical support of Red Hat a zero out of ten.

Negative

The initial deployment is easy. I can deploy Red Hat Enterprise Linux myself using a base image within a few minutes both on-prem and in the cloud.

The implementation is completed in-house.

We purchased our license from Red Hat.

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

Cloud vendor lock-in is inevitable when we adopt the cloud. This is because once we adopt a cloud service, such as DynamoDB or AWS, we become dependent on that provider for support and maintenance. It is very difficult to work with multiple clouds 100 percent of the time, as this can lead to problems with failover and other issues in multiple cloud environments because the risk is high.

The Red Hat Enterprise Linux ecosystem is more attractive because we are not just buying an operating system. We are buying an ecosystem that helps, supports, and secures our platform. I believe this is the better option.

Applying patches in the new versions of Red Hat Enterprise Linux is more time-consuming than in Oracle Linux because Oracle Linux does not require legacy environments to be patched or changed through applications.

For someone looking for an open source cloud-based Linux OS instead of Red Hat Enterprise Linux, I recommend AWS Linux. It is a very stable version of Linux and does not require a subscription.

We have a private banking client who initially started to use Red Hat Enterprise Linux for approximately 30 nodes. They found that Red Hat Enterprise Linux was the perfect operating system for implementing Ansible automation and managing their infrastructure efficiently. They also deployed Red Hat Ansible Tower for centralized management. Due to the stringent security and compliance requirements in the banking industry, they chose Red Hat Enterprise Linux as their preferred operating system to ensure security and governance across their infrastructure.

In terms of clustering, Red Hat Enterprise Linux provides robustness and scalability compared to non-Red Hat Enterprise Linux operating systems. Clustering is not as straightforward with non-Red Hat Enterprise Linux systems. Red Hat Enterprise Linux's scalability is particularly important for us. We utilize Red Hat Enterprise Linux as the operating system to achieve scalability in our operations.

Moreover, Red Hat Enterprise Linux's strong security posture and its ability to scale applications on emerging technologies across the hybrid cloud is next-generation. I believe that's what people are seeking in Red Hat Enterprise Linux. It is built with a strong focus on security, ensuring effective governance and managing security aspects well. We have high hopes that Red Hat will continue to invest more efforts in enhancing security. When it comes to container-based applications and microservices, Red Hat Enterprise Linux plays a crucial role in the hybrid cloud environment.

One challenge we've faced is with databases. Configuring and implementing DBs is much easier in non-Red Hat Enterprise Linux systems, especially in Microsoft. However, as a partner, we faced some challenges with Red Hat Enterprise Linux, particularly when it comes to enterprise applications, especially on the IBM side since it's an IBM core company. There are still several IBM products that need to mature on Red Hat Enterprise Linux. Additionally, we require more comprehensive documentation. We face difficulties with the limited availability of documentation for Red Hat Enterprise Linux. It's a different community compared to the Microsoft market, so we need the right documentation to encourage end users to use Red Hat Enterprise Linux.

We've been using Red Hat Enterprise Linux for the past seven years. As a business partner, we use the application deployed for our clients, providing consulting services. The clients run their workloads on both Red Hat Enterprise Linux and non-Red Hat Enterprise Linux systems. They have two options for cloud providers, hybrid deployments on IBM Cloud and AWS.

The benefit of using a hybrid approach is often discussed when it comes to migrating workloads to the cloud. Due to the OpenShift community, Red Hat Enterprise Linux has become the preferred operating system as it provides stability and frequent patches and fixes. Maintaining the total cost of ownership is also more manageable on the cloud.

It's excellent; in fact, it's the most stable. The presence of kernels is the key factor contributing to this stability. When it comes to security, scalability, and robustness, Red Hat Enterprise Linux (RHEL) excels in all aspects. That's why we rely on this operating system. Personally, during my time as a technical assistant from 2015 to 2016, I installed a couple of IBM applications. I found that everything ran smoothly on Red Hat Enterprise Linux without any failures.

So the stability in Red Hat Enterprise Linux is remarkably good.

The scalability is nice. Red Hat Enterprise Linux doesn't encounter any issues as a supporting core. It can scale effortlessly.

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.

Regarding centralization, we have a combination of on-premises and cloud environments where development activities take place. Currently, I don't see a specific use case for centralized development and operations, but Red Hat Enterprise Linux is being widely used both in on-premises and cloud setups. As for hybrid deployments, I haven't personally come across many instances of it. There may be a few customers who are utilizing it but not with us thus far.

Red Hat Enterprise Linux's built-in security features in terms of ensuring application and container portability are not an easy task. Although it's not my personal experience, I've observed that in the industry, there is a lot of discussion about moving toward container-based applications. However, only a small number of clients, especially those in highly regulated industries like banking, government, and oil and gas, have actually embraced containerization. They are facing significant challenges when it comes to adopting container-based applications. Many of them still rely on legacy systems running on-premises, such as mainframes.

I have seen an ROI. The most important determinant is the security aspect. Because you rely on the security of Red Hat Enterprise Linux, that's something you are paying for.

When it comes to Red Hat Enterprise Linux pricing, I have a case to share. We recently sold Red Hat Enterprise Linux OS to one of our clients. Before that, I had another client who had concerns about the OS licensing and Red Hat Enterprise Linux's pricing model. The licensing model needs to be more flexible and dynamic because the cost of a single operating system license is relatively high. I'm not suggesting a reduction in cost but rather the introduction of a different model that allows clients to choose scalable options. For example, if a client has licenses for a few operating systems and wants to expand to 50, 100, or even 200, there should be a proposal that offers them flexibility. 

Currently, most clients tend to opt for a limited number of licenses and rely on the community for additional usage, which results in revenue leakage. Red Hat should consider adopting a more aggressive open license policy that encourages higher volume licensing with clients.

When you use Red Hat Enterprise Linux in production, it's worthwhile considering the cost. But even for non-production environments, the client will definitely calculate the expenses since it's a massive implementation for large clients with an operating system. You will open your laptop, and you just need an OS. So my suggestion is for Red Hat to create a business model that also targets the user level and desktop level, where Microsoft is widely used. Considering this eventuality and how many people are switching or still using Red Hat Enterprise Linux, we, as a partner, mandate that all our Red Hat team members use Red Hat Enterprise Linux. We don't allow them to use any Microsoft operating system or other operating systems. When engineers join the company and work in the Red Hat pillar, they have to use Red Hat Enterprise Linux.

Red Hat Enterprise Linux's built-in security features, in terms of simplifying risk reduction and maintaining compliance both maintaining compliance and security, are essential aspects. Compliance requirements vary across different industries, such as banking, with each industry having its specific rules. However, security is a common concern that applies universally. Therefore, we need to address both areas.

Red Hat Enterprise Linux provides various logs and event triggers that assist in monitoring the operating system's security. Since the operating system sits as the layer between the hardware and the application, it plays a crucial role in safeguarding against security breaches and penetration attacks. A secure application relies on robust application security, followed by a well-protected OS. By ensuring the OS's security, we can establish a strong foundation for the entire ecosystem. If the OS is secure, we can confidently state that the application is at least 80% secure.

Overall, I would rate the product an eight out of ten.
