Red Hat Enterprise Linux (RHEL) Reviews

I use it for almost everything. I run a company in South Texas and Mexico. We are a cloud service provider, and we have implementations for almost everything. We are using it for websites, virtualization, orchestration, and containers, and we are also using it a lot for telecommunications. We use almost all of its features.

We have many versions. We have versions 8, 9, 9, 9.1, 9.2, etc. 

When we implemented all the security frameworks with RHEL three years ago, that was the first time we had a non-issue audit. It was a great implementation.

It helps with the headcount. With the kind of orchestration and automation that we have, we don't need a lot of engineers. We can have fewer engineers on site.

There is reliability. We can rely not only on their operating system but also on their server. Red Hat not only has operating systems; it also has many different servers.

It helps to achieve security standards certification. It is one of the most important things that I do every single day. We need to comply with a lot of frameworks of security, such as ISO2701, ISO2717, ISO2721, PCI compliance, and HIPAA for the health sector. We also have some local compliance requirements. For example, in Texas, there is one for financial entities, and in Mexico, there are several based on GDPR. It is very important for us.

It is helpful when it comes to building with confidence and ensuring availability across physical, virtual, and cloud infrastructures. There are many features to ensure or enforce high availability.

It helps us to centralize development with OpenShift. We don't do a lot of DevOps, but we have a supply chain where everything goes to the on-premises cloud, and then it is pulled to the public cloud.

The Red Hat support is most valuable. My team and I are really good at Linux, and we can do almost everything in any kind of Linux solution, but sometimes, we have a really nasty problem, and the Red Hat engineering support at the third level has been fantastic. They know how to fix almost everything. The reason why I pay so much money to them is to have this kind of service and assurance.

Containers are the strongest feature that they have. In terms of the quality, between VMs and containers, Red Hat with OpenShift is fantastic. I have more than a million containers right now in my cloud, and it works fantastically.

Network virtualization resources could be better. When you have any kind of trouble with network virtualization, such as with OVS, which is like a switch in a virtual environment, it takes many hours to find what is happening. Other vendors, such as VMware, and even other Linux implementations for network virtualization have better resources. It is much easier to escalate, and there is better documentation.

I don't use Ceph, which is their software-defined storage, because they don't have the best price. It doesn't make sense when you compare it in terms of the hardware cost, better performance, and better capabilities. That's my main complaint at any meeting with Red Hat. I want to use Red Hat Ceph, but it costs so much money.

I have been using it for about 20 years.

If you have the correct hardware, it is stable, but if you do not, you will have a problem any time soon.

It is reliable. If you don't know how to secure your Linux implementation, Red Hat can do it for you with two or three simple clicks, and you will be very secure without any kind of knowledge.

It is scalable. It is not the most scalable in the Linux area, but for 99% of the companies, it is scalable enough for any kind of workload.

We have plenty of clusters, and we probably have more than 400 servers. We are a private cloud solution provider. We don't have anything in the hyper-scale, such as AWS, Azure, etc. We own everything: the data center servers, racks, networking, and storage. That's our competency, and this way, we can provide a better solution to the kind of customers we are focused on.

We have three different locations: one in the states and two in Mexico. At each location, we have at least three different clusters for three different market verticals. We have one for the financial, one for the healthcare system, which has a lot of compliance requirements, and one for the general public, which doesn't have too much sophistication.

We plan to increase its usage, but it is not my decision. If I sell more, I will buy more.

They are exceptional. We have a lot of experience in these matters. Usually, when we have any kind of issue, it is a really difficult one, and I need to talk to somebody at level two or three in the support area. They skip the line for us because we send everything perfectly documented to open the PR. They put us in touch with the best engineer to solve the issue. If the engineer isn't able to understand what is happening, usually, he calls the RHEL developer or engineer that handles that part of the code. They are usually able to fix a complex problem in less than eight hours.

Their support is fantastic. I have dealt with many different vendors, but Red Hat is the only one that does it in this way. They do it in a simple and fast way. They understand you, and they are willing to help you and fix everything. If you have a problem or situation that is causing downtime for the customer, they understand that it has an impact on your business, and they are affecting the revenue of the company. They are really committed to fixing it as soon as possible. I would rate them a 10 out of 10.

Positive

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.

I am no longer involved in its deployment. I last deployed it about four years ago.

In terms of maintenance, every server requires some kind of maintenance, but we have everything automated. We don't put any effort into it. 

We have 8 to 12 people for deployment and maintenance. They handle the deployment and change of the environment in the data center. For DevOps, I have another team of probably 30 people. They develop solutions for customers.

We have definitely seen an ROI. The return on investments comes in the 14th or 15th month.

For the basic operating system, its price is fair. It is not cheap, and it is also not expensive. For the OpenShift or OpenStack implementation, the cost is a little higher than what I would expect, but it is doable. For a storage solution, it is almost impossible to pay.

In comparison to open-source competitors, RHEL has the most cost-effective open-source subscription model. The way I pay for everything, such as Ubuntu or RHEL, is very similar. When you compare how much money I put in for a customer, in terms of licensing, or even support, my margins with RHEL are really good. If I compare it with VMware or Hyper-V, which are not open source, the difference is totally insane.

I am a vendor-agnostic solution provider. If my customer needs something with RHEL or something that's specifically with another vendor, I use that. If they don't know, or there is a new implementation, I surely send everything to the RHEL implementation. In the end, this is not my decision. It is a market decision. If my customer is telling me that they should be on RHEL, I will bring in RHEL for them.

I would advise paying for the enterprise-level support at least for the first year.
For sure, it is expensive, but it would be helpful. With experience, you can downgrade to the second level.

We have had some issues with container compression that broke everything. So, I don't recommend using it if you don't know how to fix everything.

The biggest lesson that I've learned from using this solution is to read before starting the implementation.

I would rate it a 9 out of 10 because there is nothing perfect.

We have warehouse management systems (WMSs) where we run Oracle as our database. The app tier is basically Java. We are using a vendor-supplied Java, and the application itself is managed by the vendor. There are just one-offs here and there, such as utility boxes, but the majority is Oracle and the application that connects to Oracle.

On larger systems, like HANA, we have it deployed physically. On everything else, we have deployed it in a VMware environment. It is all on-premises. While there is some cloud, that is being done by contractors. 

We are on versions 6 through 8. As soon as version 9 gets released to GA, I am going to start working on getting that image ready. Currently, about half our images are on version 8, two-fifths are on version 6, and then version 7 is squeezed in-between.

The solution provides features that help me tweak or configure the operating system for optimal use, such as Insights Client, which I have used quite a bit to help me.

Our users are removed from the environment. They don't really know that they are running on RHEL. There have been very few complaints about speeds, application, or stability on RHEL platforms. Whereas, on Windows platforms, there are a lot of complaints.

Satellite 6.10 and RHEL integrate with each other perfectly. This integrated approach enables me to be a single person managing my images since it does a lot of the manual labor that I used to do, such as building patches, doing system maintenance, and keeping systems consistent. It does all that stuff for me. So, it has offloaded those responsibilities, giving me more work-life balance.

It is a bit on the pricier side. However, due to the stability and support that they provide to my management and me, we really don't see a reason to choose another way to go. Red Hat offers excellent support in a sphere where it is difficult to find good support.

I have been using RHEL since 2013.

It is a good operating system. It is very stable. It does not take a lot of maintenance. You set it up well and it runs. To give some perspective, we also have Windows admins. That team is about six people and growing. They manage twice as many servers as I manage, keeping them busy all the time. Whereas, I pretty much have a life; the work-life balance is very good.

RHEL is very stable. You build an image and deploy it, then it runs.

As far as the operating system contributing to reliability, it is very stable and has low maintenance. It keeps running.

We found that two of our outages in the past eight years were related to the operating system. All our other outages were related to the application and the use of the application.

I don't find the solution’s tracing and monitoring tools impact performance at all.

We can scale out. When we need more machines, we just build more machines. That is not a problem. We don't do the scale ups or any of the other scaling that is out there. That is partially because of the way our applications work. You need to scale according to the application. If the application requires new nodes, we just spin up another node and it is no problem. I could run 10,000 images, and it is not a problem.

Because we buy companies, we will probably continue to increase the usage of RHEL. I don't think that will be a problem because it is so stable. We are running about 200 images right now and about 60% of those are in production. I can't see it shrinking, but I can see it growing.

I like the fact that they really dig into things and then provide answers. As the single Linux guy, I kind of need that second admin next to me sometimes to say, "Hey, what about this?" and I am able to do that through the portal. I get my questions answered and trouble tickets resolved.

The technical support is superior to many vendors with whom we interact. They pay attention. Rarely will I run into a support person who doesn't seem to know what they are doing, then it doesn't take very long to get the issue escalated to somebody else. Out of a hundred cases, I have probably escalated three times. I would rate the support as 10 out of 10.

Positive

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.

The initial setup of RHEL is about 10 times easier than Windows. It is literally just click, click, bang. It just installs. If you have a problem with the install, you just reinstall it. It takes very little time to install, about 10 minutes. As a base image, it is very easy to set up. Then, you have post tweaks that you need to do, and I have scripts for that. Since I can script it all, I just run another command, then boom and it is all done.

For my implementation strategy, I build the gold image, which is basically just going through the CD and making my selections for a base image. Then, I freeze that image, which is on VMware, and run my scripts. My scripts basically set up logs for auditing. Whether we are going to ship logs or keep logs locally, it sets up the basic users. For instance, it will set up my account with pseudo access so I can do the remainder of the work using my account with pseudo access. It sets up tracing, the host name, IP addresses, and ESXi host files. It sets up the basic fundamentals of an operating system and gets it ready for deploying the application. 

There are also different kinds of file systems that need to be deployed and additional users that need to be added. Those are all manual processes.

We have one admin who manages all the images. That is the return on investment. The company hasn't had to hire a second admin (FTE) to keep things running.

We have moved to the Simple Content Access (SCA) model. It is much easier to do renewals and see how I am using my licenses. I used to have to do it all by hand. It would take me a good couple of hours every few months to make sure that we were up to snuff on everything. However, with the new model that they have, this is very easy. I just go to cloud.redhat.com to look and see how I am utilizing my licenses. If I am running out of bounds, I can find out why. If it is simply that we have images that need to be removed, we remove those images. If we need to buy more licenses, then we can start the process of purchasing more licenses.

I think it is worth the price. I wish the pricing was a little bit more friendly, so when I go to my boss, he tells me, "That's too much money." I can say, "It's not too much money."

Especially if you are a newbie, buy the support and use the support. Get a couple of images going and really play around with them: crash them, burn them, and figure out how support functions when you have a really gnarly situation. Otherwise, it is just inserting the CD and booting the machine. It is very easy to set up and run.

I have looked at SUSE or Ubuntu. They are so radically different in their total management, e.g., everything from getting packages to configuration and in how that is all done. Therefore, it would be a learning curve to go to another solution. So, there is benefit in staying with RHEL. 

I do not have a lot of experience with Ubuntu or SUSE. Those would be the bigger contenders. The thing that I keep coming back to though as I'm talking to vendors and VARs is that though SUSE is a contender out there in the SAP landscape, RHEL has the stability. SUSE appears to function more like a desktop operating system ported to a server environment, whereas RHEL is built from the server hub. The management tools show that. It is a mature management infrastructure.

There are some things that are nice about SUSE. People talk about their app configuration wizards, but if you're coming from a Unix background overall, RHEL feels like a real operating system.

My interaction with Ubuntu has been as a desktop. It is very GUI-oriented. In my estimation, it is more like a toy. It is deployed in server environments, but it is more because admins are familiar with the desktop version of it. They just port that over as opposed to having grown up on Unix and moved into Ubuntu.

A Unix admin will prefer to go into something like Red Hat, Rocky Linux, AlmaLinux, or even Oracle Enterprise Linux because they will simply feel much more like a data center operating system than some of these other solutions.

RHEL provides features that help speed deployment. I am currently learning how to take advantage of those features.

As far as deployment goes, I build a golden image VM and just deploy the images themselves. I don't really use any RHEL tools specifically for the deployment portion.

The solution is constantly expanding and moving into new areas, like jumping into the cloud.

I need more experience with their self-monitoring tools. That is the one area where I feel like I am lacking. I am still using a lot of the stuff that I learned in the Unix realm. I haven't really matured into using the specifics that are being supplied. I am a member of the accelerators team and have been exposed to some of these tools through their lectures. I am starting to play with them a little bit, but I have not fully gone into that arena. So, there is improvement needed on my access to RHEL.

I would rate the solution as 10 out of 10.

My customers primarily use Red Hat Enterprise Linux for application hosting and small databases. It is used for hosting Java applications and small web servers.

Cloud-based Red Hat Enterprise Linux deployments provide cost savings. If customers are purchasing a physical server, they need to have a proper setup. They need to have a data center, cabling, and a lot of other things. For cost-saving purposes, they are going for a cloud. As an operating system, it offers the same functionality on-prem or on the cloud.

It saves money for company owners. It helps our customers save money and do things quickly. They can build servers quickly. There is a menu where they can fill in the VM name and other details and attach storage. In ten minutes, they have a server ready.

I am Red Hat certified. I train people in corporations and educational institutes. Red Hat's material is very good. Their testing system is awesome. If someone is certified in Red Hat, you know that they know it well. There are millions of videos on YouTube, but they are not always updated. On the Red Hat site, the documentation is very clear. You just need to focus and study for two to three months to get certified.

Nowadays, delays are common with their support, and it often takes time to get assistance from experienced engineers.

I have been using Red Hat Enterprise Linux for seven to eight years.

Red Hat Enterprise Linux is an excellent product, and its stability has improved significantly over time. It can operate for extended periods, like six months to one year, without issues.

Red Hat Enterprise Linux scales well with increasing user demands or infrastructure size. It is easily available and efficiently adapts to varying needs.

Most customers host medium-sized applications on the cloud. Storing a big application can lead to higher costs.

The technical support from Red Hat has declined over the past four or five years. It could be because there are not many skilled people. When we raise a case, it is attended by junior people or new people, which wastes two to three days. We might even have to raise the severity of the ticket. However, when senior people take ownership of the case, the support is awesome. They give proper support. This was not the case earlier, so whenever we raised a ticket, we got an immediate response from Red Hat.

Positive

The initial setup is smooth.

We have Cloud-based deployments. We are using AWS, GCP, Azure, and other cloud platforms. We also have on-premises deployment. Some customers also have a mixed deployment with the cloud and on-prem but in such environments, I have seen problems in terms of performance. For example, if my database is on-prem on Red Hat Enterprise Linux, and I am storing my application on the cloud on Red Hat Enterprise Linux, whenever someone hits the website, there will be latency issues. I sorted out such issues for a customer. I suggested they migrate their server from the cloud to on-prem because their database was quite big. With a mixed setup, they were having a lot of issues in terms of performance and storing data. It was very slow. After they moved it on-prem, it was much faster. This is not a Red Hat-related issue. From the operating system side, no improvements are required. However, cloud providers need to improve their facilities.

For patching, I use Red Hat Satellite, and for configuration, I use Red Hat Ansible. Leapp upgrades are also awesome. A month back, I upgraded Red Hat Enterprise Linux 8 to Red Hat Enterprise Linux 9. I created detailed documentation about the procedure. There were about 14 steps. It was straightforward.

With Red Hat Insights, we can see the security threats. Red Hat Insights is integrated with Red Hat Satellite. It will be helpful from the patching point of view. It lets you do subjective analytics of servers.

I did some research on pricing a long time ago, and at that time, it was much cheaper than Windows. I do not have current details about pricing, but it is affordable.

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

Our use case for Red Hat Enterprise Linux is for production applications. 

We are a Managed Service Provider. Red Hat Enterprise Linux enables us not to be worried about vulnerabilities, security, and patching.

The most valuable features are the subscriptions and upgrades. 

We need to have more flexibility on the developed versions. Not everybody is ready to subscribe to enterprise versions. They would like to test the tool without subscriptions. 

We chose Red Hat Enterprise Linux because of its security. 

We use Red Hat Enterprise Linux with AWS. We started our practice with AWS, and most customers use it instead of GCP or Azure. We use the product in a hybrid environment, mostly when shifting the containers or existing workloads from legacy systems. 

Most of the customers use Red Hat Enterprise Linux because it is the only approved OS. The tool's knowledge base is good but is limited to subscriptions. 

The upgrade migration is straightforward. For the initial projects, we used to execute CLI scripts. We plan to upgrade the system if everything works well in the lower environment. 

I have used the image builder feature. I rate the overall product a nine out of ten. 

We primarily use it for OS purposes. 

It's very good for support compared to other operating systems. For decades, it's been providing good support and service. Even during implementation, there's a dedicated team to answer any queries. We are a very big company running critical applications and having that support is very important.

The patching tool is good. We're also introducing the possibility of automation.

The built-in security features are okay when it comes to simplifying risk reduction. It makes life easier, especially in regards to the lifecycle and what we need to install, et cetera. The features and tools help us to maintain security overall. 

It is easy to maintain compliance.

The portability of applications and containers is good. Now we are just starting with the containers and anything related to Kubernetes. 

Red Hat is always providing security on time. Any vulnerabilities are immediately dealt with to fill the gap and deal with the issue.

It's a good tool. I'm very confident with this product.

The system role features for automation security configurations, et cetera, for Ansible, we started using it. We are new in terms of automation. We'll start to use it heavily in the near future. Ansible is another great tool from Red Hat.

It enables us to maintain consistency across systems over time. My role is to maintain stability, even during upgrades and patches. So far, it's been a positive experience. We use the entire ecosystem around Red Hat.

We use Red Hat Insights. From a security perspective, we may stop using it. With Insight, if you have Red Hat Satellite, it gives you an in-depth view of everything. The only thing missing is the insights related to performance. We may not continue with it. We'll see if we'll push it and have everything on the cloud. 

In the area we are using it, we are satisfied.

Maybe in OpenShift, which is our next step, there can be more improvements with integration with Kubernetes. We're not experts there yet. 

Maybe it could have a better user experience and less coding. Reducing the effort for the end user or administrator would be ideal to make daily operation and maintenance easier. 

If they can make the integration with Ansible easier, that would be ideal.

They should offer more in terms of learning materials to make learning easier. 

They need to make things more affordable or accessible. 

The solution is stable. We barely have any issues with a server setup. So far, it's manageable. The biggest challenge is the criticality of releasing patches. When we have any critical alerts we action them. We tend to try to wait for the release of a stable version. 

How many people use the solution depends on the application. We likely have thousands of users. We do have some products that maybe only have a few or a few hundred. 

We've had no challenges with scaling. It can support any type of load within the data center. 

Support is excellent. 

Positive

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. 

I was involved in the deployment. Our team managed the process. It's pretty straightforward. We handle implementation, tuning, and patching. 

How long it takes to implement the product depends. We're trying to mitigate the time by automating with Ansible. We want to handle one VM or server in five or fewer minutes, however, it can take days. At this point, we can provision servers in a few minutes. It's becoming faster. 

We have a team of ten to run the infrastructure on the OS level. 

I'm not an expert on ROI. We are paying to use the solution, however, the utilization we get and the support both offer good value. 

The pricing model isn't something I deal with directly. The pricing is fair, especially compared to virtualization like VMware. We do use VMware and are thinking about moving sandboxes and testing over to Red Hat. This may end up being a big cost savings with our CAPEX and OPEX. 

From the price level, the cost is almost the same for us, if we look at Red Hat versus SUSE, however, we get a higher level of support with Red Hat. 

Red Hat was always our first choice. 

We're a Red Hat customer. 

I'd rate the solution nine out of ten. 

We are a telecommunications operator using Red Hat Enterprise Linux for our technical applications due to its supportability and robust management features.

Red Hat Enterprise Linux's built-in security features aid in simplifying risk reduction. In the past, patches fortified the security features, but now, with playbooks, we can automate and address any findings for any Common Platform Enumeration. When integrated with Red Hat Insights, the solution can identify the CPE and provide the remediation playbook. This expedites detection, remediation, and testing by Red Hat, thanks to the playbooks provided by satellite as well as malware detection.

Maintaining compliance with Red Hat Enterprise Linux is easy because it supports various out-of-the-box compliance policies, such as CIS. Whether we are running OpenSCAP on-premises or Insights, we can perform compliance testing using OpenSCAP to verify adherence to the Red Hat Enterprise Linux security guidelines, as well as other well-known guidelines and framework compliance. I have found that all the compliance policies I required were already included out of the box.

Red Hat Enterprise Linux is ready to help keep our organization agile when it comes to the portability of applications and containers because all the applications are developed by the vendor. Red Hat Enterprise Linux is the preferred choice in our industry because the applications we use are swiftly certified by the vendor, so we don't have to verify them ourselves.

Red Hat Enterprise Linux provides enhanced security for our servers, and we are aware of patching requirements in advance. Additionally, the pre-certification of Red Hat Enterprise Linux applications expedites deployment as we no longer need to go through the certification process ourselves. Moreover, Red Hat Enterprise Linux offers excellent support, ensuring that any issues that may arise are promptly addressed, which is crucial for our environment where we must maintain an uptime of 99.99999 percent.

Red Hat Enterprise Linux enables us to achieve security standards certification because it is driven by various compliance policies that include everything we need out of the box. This makes it easy to enforce security rules, and security patches are applied regularly. With Insights, we have malware detection, CPE filings, and remediation capabilities. In addition to the reactive approach, we also benefit from a proactive approach, allowing us to stay informed about the events around us, which helps us implement temporary solutions if needed until a permanent fix becomes available.

With Red Hat Enterprise Linux, we can build with confidence, knowing that it is available across physical, virtual, and cloud infrastructures. The operating system provides certifications, ensuring that we can deploy with 100 percent certainty, knowing that the applications will work. Additionally, it offers identity security and excellent support from the Red Hat team. Without this support, we would have to rely on searching within the community and downloading untested patches, which may function in small environments but not for larger ones with sensitive applications.

Red Hat Insights helps us prevent emerging issues related to security or noncompliance settings. One of the steps we take before going live is using OpenSCAP to ensure compliance with our standards. This is followed by our own security scanning and verification process. If any issues are not known within Red Hat, we can always refer to all the findings. Once the system is in production, regular monitoring allows us to use Insights to identify any new findings and apply necessary patches or workarounds. The knowledge base available on the servers enables us to take proactive measures even before a security patch becomes available. The new malware detection feature in Insights helps protect end-user information.

Insights provide vulnerability alerts and specific guidance. With each system, we can view the detected Common Platform Enumeration and receive advice on how to address it. These features have protected our systems from potential attacks, thereby increasing our uptime.

Red Hat has introduced a fast server, where Red Hat Enterprise Linux can be integrated or connected to via a client. This connection allows us to identify numerous vulnerabilities in malware easily and facilitates simpler patching. Activating the Red Hat addons on this server creates a perfect match when seeking a well-hardened OS using the gold image, as it eliminates the need to address issues from an existing image. Additionally, Red Hat Insights is a valuable and essential tool. In the telecom industry, we rely on basic products that necessitate an OS with robust security support and regular patches. 

We have not succeeded in creating an image from Red Hat Insights for Red Hat Enterprise Linux, including custom partitioning and custom scripts. This would have been helpful.

Red Hat Insights reporting can be enhanced by incorporating performance components, making it a central tool for vulnerability assessment, compliance monitoring, and much more. The performance component is available on Red Hat Enterprise Linux, but we need to maintain the dashboard on-premises, which requires us to switch between systems instead of performing all tasks from a single location.

Managing the destination for netting on the Netserver using Red Hat Enterprise Linux could be made more user-friendly.

I would like to have enhancements in the data files to help with deployments.

I have been using Red Hat Enterprise Linux for over ten years. I started in 2012 using version five.

Red Hat Enterprise Linux is stable.

Red Hat Enterprise Linux is scalable, but the scalability is achieved at a different layer compared to adding memory to a virtual machine or container.

Compared to other support departments for Red Hat products, the Red Hat Enterprise Linux support team stands out as one of the fastest, most cooperative, and understanding teams.

Positive

The initial setup is straightforward. In the past, it was complex when Red Hat acquired Ansible because many of the modules were community resources that lacked full support. As a result, creating a playbook to deploy the OS was a painful process, as there was a chance it would not work, and we would not have the necessary support. However, currently, deploying Red Hat Enterprise Linux is easy. We have never deployed only one operating system at a time, but it would take less than one hour to do so.

I would rate Red Hat Enterprise Linux an eight out of ten due to the complexity of its network boost management issue.

We have Red Hat Enterprise Linux deployed in one location.

Red Hat Enterprise Linux is used in our environment to run the application for all of our customers, and only around ten people have access to it.

Red Hat Enterprise Linux requires maintenance for applying new patches, releases, and debugging. 

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 the solution majorly for JBoss, Apache, Java workload, and Comcast. We also use it for Apache Sattelite to do all the patching and database management. We use it for almost everything. We were a pure RHEL shop, up until recently. 

The most valuable feature is Satellite. Its consistency in patch upgradation is great. For the ten-year lifecycle, we have been able to rely on it and not worry if the patch will break. We do not need additional patching features since it covers everything.

The Modules feature is awesome but it could be even better.

We have been using the solution for 25 years.

The solution is stable. I have never remotely questioned its stability. The downtime is rare. It is usually a vendor's application issue unrelated to it. 

My company only has one complaint; we have been using it for more than seven years out of its ten-year lifespan and have yet to receive any version update. The drivers have become stale. We are trying to upgrade them manually. It would be nice if they had updated the drivers. If they do not update them, the solution will end soon. They should prevent it from crashing every time we try to update it. We are still rolling Ansible to automate some of the functions but, it is complicated to process with a vast sync of firmware and drivers.

The solution is scalable. I am a Satellite owner and we've had scaling issues with it. Those issues are mostly because my company didn't make it scalable in the right way.

They have their own expectations of how to make something highly available. And Satellite doesn't fit into that. 

I rate the solution's technical support as nine out of ten, as there is always room for improvement. I never had an issue with the support services. It is good and worth the value. 

I don't usually put up a ticket for every minor error. I am an expert and know the technicalities required to resolve the issues. So, whenever I contact them, I expect it to get somewhere. Because most of the time, the executives put more than one problem in the same ticket unrelated to another. It becomes more complex and confusing.

Positive

Red Hat Enterprise Linux generates a return on investment. We have everything on it. We have Windows servers for SharePoint and multiple cloud providers as well. In addition, we have OpenShift and Docker Enterprise, and some other open-source applications.

The solution is a good value for money. They keep adding up essential features to the specific subscription plan. I am also not a big proponent of top-level open-source applications as they do not provide support services. Whereas, with Red Hat, I can call them for queries and get answers immediately. In comparison, open source doesn't have that facility. Even if you hire a support vendor, they just give their opinions and try to help but they don't own the project.

At the end of the day, we have a 999.99% reliability of only 20 minutes a year of downtime with Red Hat. It is impossible to get that with open-source vendors as sometimes the applications might break if it doesn't notify about the changes on time. Conversely, Red Hat Enterprise Linux has a ten-year life cycle assurance, so we don't have to worry much. Also, we are in a TAM program. Thus, we can call the support team immediately for any issue.

Our organization constantly evaluates other options, as Red Hat Enterprise Linux's cloud version doesn't offer new features. Other than that, we go back and forth using Centralized and Rocky Linux. We prefer the ones we don't have to pay for the licenses.

It has a strong security posture. I did a SELinux contract for my current company. Compared with open-source alternatives, Red Hat Enterprise Linux provides better support services and reliability. Also, we are rolling out a new Ansible platform for insights. It gathers information about how many jobs we have, how long they take to complete, etc.

We need to manage vulnerabilities for a massive base of clients' systems. We don't use open-source apps for it like Red Hat. We have a third-party tool as we straddle different compliances. However, Red Hat is great about security announcements. I can call them anytime for an update as well. But it is challenging to work with the vendor for scanning machines. It does not know how to work with Red Hat packaging version numbers.

I rate the solution a nine out of ten.
