Red Hat Enterprise Linux (RHEL) Reviews

Red Hat Enterprise Linux serves various functions, including operating system tasks, satellite management, and OpenShift deployments. Additionally, we utilize Red Hat's Insight and Subscription Manager products.

Our organization utilizes Red Hat Enterprise Linux, both on-premises and in the cloud. While we maintain on-premises systems, certain departments also leverage Red Hat Enterprise Linux in a cloud environment. As the license manager for Red Hat in our organization, I can confirm that we have a substantial number of Enterprise systems operating in the cloud.

Red Hat Enterprise Linux offers key benefits for enterprise management, including features such as patch management, resource isolation, enhanced stability, and improved performance through automation. Unlike its earlier versions, Red Hat now provides these functionalities out-of-the-box, eliminating the need for extensive scripting and streamlining administrative tasks. Red Hat introduced an online patch management system in Red Hat nine, similar to what AIX offered years ago. This system, which likely will be included in Red Hat ten and eleven, allows for online patching without requiring a reboot. This is a significant advantage for enterprise companies who cannot afford downtime, making Red Hat an even more attractive option for them.

Looking beyond a Red Hat-centric view, hybrid cloud computing significantly enhances customer service. Whether through new service offerings, modernized workflows, or improved scalability, automation, and high availability inherent in cloud solutions, the benefits are clear. Furthermore, Red Hat Enterprise Linux provides stability, avoiding the reboots and challenges often associated with Windows environments. Therefore, hybrid cloud adoption is a strong strategy for enterprise companies, offering substantial advantages.

To enhance future development centralization, our development teams are transitioning to Red Hat Enterprise Linux on our development servers.

Red Hat Enterprise Linux has robust built-in security features that effectively contribute to risk reduction, business continuity, and compliance maintenance. Red Hat demonstrates a solid commitment to security by providing timely updates and fixes to its customers. While the operating system itself is secure, it's important to note that Red Hat Enterprise Linux provides a foundational image that requires further hardening through the implementation of security controls. Red Hat empowers users with a platform and a range of hardening options, enabling them to tailor security measures to their specific application needs. Furthermore, Red Hat's rapid release of fixes and updates, often within a day or two of a vulnerability discovery, ensures that customers have access to the latest security enhancements.

The portability of applications and containers built on Red Hat Enterprise Linux fosters organizational agility by enabling a continuous cycle of learning, trying, adapting, and iterating. Containers offer a streamlined approach to development, allowing for rapid deployment and effortless updates. If a containerized application doesn't work, it can be quickly destroyed and recreated with updated components, significantly reducing deployment time compared to traditional methods. This rapid iteration aligns perfectly with agile principles, enabling organizations to respond swiftly to changing needs and requirements.

Red Hat Satellite provides patching information and compliance percentages for our systems, but in a multi-departmental enterprise environment, Red Hat Insights offers a more comprehensive view. Insights synchronizes data from Satellite and provides a centralized platform to monitor compliance across different application sectors. This addresses the limitation of Satellite, which may not be accessible to all stakeholders. Insights' API-based functionality allows integration with ServiceNow, creating a single pane of glass view of compliance for various teams. Furthermore, the Insights client provides granular visibility into vulnerabilities, further enhancing transparency and management capabilities. This integration streamlines compliance monitoring and improves overall efficiency.

Red Hat Insights provides vulnerability alerts and guidance. While it doesn't necessarily affect uptime, the severity of the vulnerability determines the response. High-severity vulnerabilities require immediate evaluation to assess their impact. Multiple security layers within the environment may mitigate immediate risks. However, vulnerabilities should be addressed promptly. Insights enhance transparency and provide detailed information for timely action.

Red Hat Enterprise Linux offers many features I appreciate, especially the increasing maturity of the operating system and its automation platform. The automation platform, in particular, has significantly evolved over the past three years. Satellite, now known as Insight, is another excellent product, providing easy and convenient patch management for both managed and unmanaged systems. Its reporting on users, vulnerabilities, and other key information is also quite valuable. Having used Red Hat since version three and now working with versions eight and nine, I'm consistently impressed by its progress. The preview of Red Hat ten looks amazing, and I plan to implement it soon after its release.

The area of improvement is patch management, specifically isolating kernel and operating system patching to prevent downtime for enterprise applications.

I have been using Red Hat Enterprise Linux for 20 years.

Red Hat Enterprises Linux is stable, and improvements are constantly made.

We are not extensively using the scalability features, but the documentation and technology are growing.

I am generally happy with Red Hat's customer service and technical support. There are challenges with different time zones, but overall, the service is satisfactory.

Red Hat Enterprise Linux offers a straightforward pricing and licensing model. The subscription manager provides clear visibility into license usage and facilitates tracking usage growth over time. Although the tool is still under development, Red Hat is actively collaborating with customers to improve its features and functionality. The subscription manager enhances transparency by enabling accurate tracking of license consumption and ensuring alignment with customer needs. Red Hat Insights, working with the satellite, further strengthens transparency by automatically calculating and reporting license usage. This comprehensive approach simplifies customer license management and promotes clarity in supplier relationships.

Red Hat Enterprise Linux is a solid operating system, earning an 8 out of 10 rating. While no OS is perfect, and there's always room for improvement, Red Hat effectively meets the evolving demands of the business market.

While numerous open-source operating systems are available for development, enterprise-class companies require the stability and support of enterprise-level solutions. Red Hat Enterprise Linux bridges this gap by offering a forum for feedback and collaboration, allowing users to directly influence feature improvements and updates. Red Hat Enterprise Linux effectively combines the flexibility of open source with the robust support and reliability required by enterprise-class customers, unlike many other open-source operating systems that lack this level of responsiveness.

Our focus is on the enterprise support and open mindset Red Hat provides, looking to customer benefits and services.

We use it for SAP applications. We use it for web hosting, and then we use it for clustering.

We were previously using Windows Servers, but we had challenges with the compatibility with SAP applications, the support, and the frequency of patches. We had compatibility challenges when we wanted to go for an upgrade. We use the SAP HANA database for SAP applications, and the migration process from Windows to Linux was easy. We also got better support. While troubleshooting issues and doing RCA on unplanned events, the support we received from Red Hat was good.

Because of the reduction in compatibility issues, the number of downtimes was reduced. The escalations were reduced from the application side. The frequency of the patching was reduced, so such planned activities were reduced. With Windows, we were forced to go for patching even if the application was not ready for patching. Red Hat Enterprise Linux is a good platform for SAP applications and the database in our organization. We prefer Red Hat Enterprise Linux.

Patch management with the Red Hat Satellite server is also good. When it comes to automation, the automation tool for regular tasks on Windows was very backward compared to the Red Hat automation tool that we are now using. Red Hat Ansible is far ahead. We could automate many more tasks on-premises using the Red Hat platform as compared to the Windows platform.

Red Hat Insights helps us understand vulnerabilities and avoid any downtime and risks. If needed, we can easily reach out to the Red Hat support team for any help related to patching or changes.

The knowledge base offered by Red Hat Enterprise Linux is very good. It is easy to understand. It is not too technical to understand. New users and application support teams can easily understand the information given in their knowledge base.

Initially, we used to do installation and patching manually, but we later implemented the Red Hat Satellite server, which was suggested by their team. We started using the Red Hat Satellite server. It has made deployment, patch management, and lifecycle management very easy.

Red Hat Enterprise Linux has affected our system's uptime. Earlier, the downtime was around six to eight hours, whereas now, it has come down to one hour. We also need less manpower for upgrades.

The file system is very good. We also have flexibility. We can scale the file system and add the mounts on the go without any downtime.

On Windows, for security, we need to have many applications and supporting tools installed externally whereas we get them with Red Hat Enterprise Linux without any issues. Application management is also easy compared to Windows.

Build management is also easier than Windows. When we had to deploy an application on Windows, the process was difficult compared to the Red Hat build process.

If someone wants to build automation, we can give them access to Red Hat Ansible Tower, which was not possible with Windows.

There can be a faster resolution. When we have production issues, they take around 30 to 60 minutes to come up with a solution. It would be quite helpful if their response is faster. They are also not reachable over the phone, so we need to wait for their callback for the ticket. If they are reachable over the phone, that will be quite good. Our account manager is reachable over the phone but only during certain times. Fast help would be quite helpful in the case of any urgent issues.

I have been using Red Hat Enterprise Linux for the last nine years.

For reliability, I would rate it a ten out of ten. The downtime that we have is not because of the OS. That is generally because of the dependencies such as the network or VMware infrastructure.

I would rate it an eight out of ten for scalability.

We have around 4,000 users, but the Red Hat boxes that we use are around 2,000. 

In the case of any unplanned events, system crash, or something else, we get proper answers from their team. They help us with RCA, which is helpful in avoiding any such events in the future. We can also approach them when we want to implement something. When we were moving from version 7 to version 8, their support helped us. We could move a bulk of machines with a small downtime. The application team was quite happy because the downtime was for a very short duration.

Their support for urgent or production issues can be faster. I have had all kinds of experiences with their support. I have worked with their support for the last four or five years. We have had scenarios where we had to close a ticket with no resolution. We have also had an awesome and quick response from them. They have also helped us build up a process, which was quite tedious. Overall, I would rate them an eight out of ten.

Positive

We were previously using Windows Servers. We had challenges related to compatibility, support, and patch frequency. We were not very comfortable with Microsoft's support. Whenever we had any issues, they only asked us to reboot or wait for the patch. They kept giving us some patches. We were not comfortable with that because the applications were not ready for those patches, but they forced us to keep updating them with the patches. Red Hat support is better than Microsoft support. They do not just ask to reboot to solve an issue. They help us with a proper RCA.

We have hypervisors in the on-prem environment. We use VMware on that. We are using Red Hat Enterprise Linux on bare metal and hypervisors. It is quite comfortable. We do not see any issue with either of them. Initially, we had some issues implementing the cluster on VMware, but Red Hat along with the VMware team helped us overcome the issues.

Its deployment was quite straightforward. There was no confusion. It took us some time initially but that got reduced with the help of Red Hat Satellite and Ansible Tower. Initially, it took 30 to 40 minutes for deployment. With the help of Red Hat Satellite and Ansible Tower, it came down to 15 to 20 minutes. We also needed less manpower because the process was quite straightforward. Previously, we had a team of four, but the number was reduced afterward. 

Upgrades are generally quite straightforward because we have spent some time with Red Hat support and built a process for easy upgrades.

We had some challenges with the upgrade from Red Hat Enterprise Linux version 7 to version 8 because of certain dependencies, but the Red Hat support helped us build a process and automate it. It took some time, but it got easy.

We have not used Red Hat Enterprise Linux Image Builder. It did not match our requirements. We built our own images. After moving to the Red Hat Satellite server, image building was quite easy.

It is not fairly priced. If they can reduce the price, it would be nice. 

I understand that they do not have any big competition as of now. SUSE Linux is there, but Red Hat Enterprise Linux has overcome all the drawbacks that it had earlier. Initially, SUSE Linux was a quite comfortable platform for SAP applications, but Red Hat has improved in terms of development. Its kernel suits SAP applications very well. If they can also improve the pricing, it would be even better. They generally do not reduce the price, but they give add-ons. We can get licenses for the Satellite server, Ansible, etc.

I would recommend Red Hat Enterprise Linux because of its support and reliability. In my career, I have worked with various Linux flavors such as Red Hat Enterprise Linux, CentOS, or Ubuntu Linux. Overall, the Linux platform is very reliable for most applications. With Red Hat Enterprise Linux, we get support when we need it.

We do not use the web console much on the support side, but the application team does use it once in a while. They find it comfortable because, for application deployment, they require a GUI. We provide them with the console, and they complete their task. We do not use it ourselves. We are quite comfortable with the command line interface.

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

My main use case for Red Hat Enterprise Linux (RHEL) is server management and cloud operations.

I use RHEL for server management and cloud operations to perform multiple tasks, such as user access management, user management, patch management, and troubleshooting.

Red Hat Enterprise Linux (RHEL) offers multiple features that are really accessible and stable, providing security and compliance, hybrid cloud compatibility, enterprise-grade container support, task automation through cron jobs, and an overall good platform.

Red Hat Enterprise Linux (RHEL) has positively impacted my organization through automation, as my recent task saved a lot of time by reducing the work from months to a day using scripts developed in RHEL, thus boosting our productivity and cutting costs while empowering a skilled workforce, enabling scalable and secure infrastructure, and fueling innovation and digital transformation.

Red Hat Enterprise Linux (RHEL) could be improved with a modernized knowledge base and documentation, better performance under high load, and possibly a reduction in the cost of the professional subscription. Apart from that, I don't see much need for improvement.

I have been using Red Hat Enterprise Linux (RHEL) for more than five years.

In my experience, Red Hat Enterprise Linux (RHEL) is perfect in terms of stability.

Red Hat Enterprise Linux (RHEL) handles increases in users, applications, or data smoothly, which is why we use it for all our projects, as it provides us with confidence. We also use Amazon Linux, but primarily it is RHEL.

I have reached out to Red Hat Enterprise Linux (RHEL) customer support multiple times, and I've found the experience amazing, as issues get resolved in a lesser time compared to Amazon AWS.

I have majorly worked on Red Hat Enterprise Linux (RHEL) only and did not use a different solution before switching.

We have seen a return on investment with Red Hat Enterprise Linux (RHEL), having saved a lot of money and time due to the automation and scripting we perform, resulting in savings on man-hours as well.

I have mentioned earlier that the pricing, setup cost, and licensing for Red Hat Enterprise Linux (RHEL) could be reduced a bit, indicating a scope for improvement there.

Before choosing Red Hat Enterprise Linux (RHEL), I evaluated other options like SUSE and AIX, but I don't think any of them are better than RHEL.

We do a lot of automation using Bash scripts. In a recent task, I had about 2,500 to 3,000 EBS volumes that I needed to change from GP2 to GP3 and calculate their throughput and IOPS, which would have been impossible manually due to time constraints, but we accomplished it with a Bash script thanks to RHEL. It's really very useful.

My advice for others looking into using Red Hat Enterprise Linux (RHEL) is that everyone working on Linux should at least give it a try because it's a great platform.

On a scale of one to ten, I rate Red Hat Enterprise Linux (RHEL) an 8.5 out of 10.

The main use cases with Red Hat Enterprise Linux (RHEL) for me are hosting Oracle databases, Oracle server database, and MariaDB. When we need to install Oracle, we put it on Linux, and it usually was Santos in the past. Then we moved to Oracle Enterprise Linux or Red Hat, and when Oracle released the Linux distro, we moved to Oracle because the devices are really open source.

Some of the best features of Red Hat Enterprise Linux (RHEL) include stability; it doesn't break. Stability, along with management tools and users for management tools that they add to the Linux distro, are important. The main reason is stability. In the server area, we don't want change. That's why we're trying to move back to Debian, because Debian is stable—old, but stable. 

Red Hat Enterprise Linux (RHEL) does help save time because the setup and general installation experience is very optimized and well-established. I made tests installing and setting up radioactive environments for virtual machines, and it was a very good experience, fast.

Red Hat Enterprise Linux (RHEL) is for on-premises only; we try to avoid the clouds as much as we can. In Brazil, we are seeing an interesting movement with small cloud providers because Amazon, Google, and Microsoft are too expensive. I am noticing the rise of many small companies that build small data centers and offer cloud services to small companies. They prosper with a better price and a simpler solution—not a fancy data center with sophisticated security. Just a small space with a decent Internet connection and a stable energy source, and they are good to go. People are prospering with this model of small cloud providers.

The main difference between Red Hat Enterprise Linux (RHEL) and some of the others that I'm evaluating now is that Red Hat tries to use more recent packages. The problem with Debian and some of the stable distributions is that they are too conservative, and they keep the version progress very slow. I sometimes develop and create things that need more recent packages and libraries, and with Debian, I usually struggle with that. Red Hat usually provides the new ones—stable, but new. That's one of the best features of using Red Hat. Ubuntu also upgrades some important libraries from Debian.

I have used Red Hat Enterprise Linux (RHEL) for more than fifteen years, because we have some infrastructure on it.

I assess the knowledge base offered by Red Hat Enterprise Linux (RHEL) as excellent; they have a great technology base on their website, but it requires a subscription. You might think you get free access, but I really don't prefer it. I usually find other sources. I know they have a very good knowledge base with excellent documentation, but I usually don't get access to it. I have not reached out to their support, so I do not have any personal experience with Red Hat support. The support that we really use from time to time is Oracle. My clients use the Oracle database, and they all pay for support. We use it because my partner, who is an Oracle database administrator, frequently deals with problems with Oracle and uses their support, and it works very effectively.

Positive

My thoughts on the deployment with Red Hat Enterprise Linux (RHEL) are that it's easy, there are no problems at all. It's very easy, including in the cloud; they offer many partners, and it's really easy to move your loads to the cloud with Red Hat. I believe it's easier than with Microsoft. However, my clients usually do not get involved with this; most of them are Microsoft-based.

The ROI with Red Hat Enterprise Linux (RHEL) is useful if the company requires accountability or a formal contract, because they usually need someone involved in some kind of accountability process when lawyers get involved. Only in that situation does it make sense to pay that price. Usually, companies that are required by law to have licensed products, such as banks and insurance companies, have obligations by law. This is especially true in Brazil, where the insurance market is very regulated. It makes sense for these companies to have a license contract, particularly in the case of security leaks and similar issues.

My experience with the pricing or licensing for Red Hat Enterprise Linux (RHEL) indicates that our clients never chose to purchase a license. I watched the prices a few months ago while considering buying one for myself, and they were expensive; it's not a reasonable price, especially for small companies. The business value of Red Hat Enterprise Linux (RHEL) is compatible and on the same level as other Linux distributions I have used. They all charge the same for their products. I usually don't see much difference. When I compare the price of Red Hat Enterprise Linux (RHEL) to that of Windows, they are basically the same price, just a little cheaper, a small fraction. All of these big corporations try to squeeze the clients as much as they can. The only exception is Broadcom, which seems to try to charge an absurd amount for their products.

My clients all have their own firewall solutions and network security solutions that they purchase. We usually don't deal with that. We just keep the built-in firewall running, and that's all. That's the main feature that we use on Red Hat and other distros, the built-in firewall. 

Security Enhanced Linux (SELinux) is something we do not engage with. Last week, I tried to install a new version of Oracle Enterprise Linux from Red Hat on an old HP server, Gen 5, but it did not work; I needed to go back to Ubuntu. Ubuntu, even in the new version, uses a kernel that works on old hardware, so we have to deal with this situation. If you have old hardware and need to repurpose an old server, you can't use these new distros. Even Oracle does not work with very old equipment, more than ten years old. 

I would rate Red Hat Enterprise Linux (RHEL) as a seven or eight out of ten.

I use Red Hat Enterprise Linux to manage pre-configured web servers, troubleshooting issues such as "524 errors" and missing configurations in EMV files. Furthermore, I constructed an on-premises Kubernetes cluster on Red Hat Enterprise Linux 9 and configured it for ELK.

The Red Hat Enterprise Linux knowledge base is excellent. When I encountered an error, they were able to quickly identify the issue and guide me through the necessary steps to resolve it.

The Red Hat Enterprise Linux Web Console functioned properly throughout the lab courses.

Red Hat Enterprise Linux is excellent for commercial use and enterprise tools. It's best to use Red Hat for enterprises because it provides robust support available twenty-four by seven, which I have experienced.

To start working with Red Hat Linux was straightforward and user-friendly. I didn't encounter any complexities.

The most valuable feature of Red Hat Enterprise Linux is its comprehensive ecosystem. The detailed documentation eliminates the need to consult external resources, and the knowledgeable support team provides expert assistance with both technical issues and site navigation.

Improvement is needed for supporting Kubernetes clusters because it is less supported by Red Hat according to my experience. There are also some gaps in documentation which affect configuring Kubernetes clusters.

I have been using Red Hat Enterprise Linux for four to six months.

I have not faced any downtime or stability issues with Red Hat Enterprise Linux.

I have not encountered any scalability issues with Red Hat Enterprise Linux.

The technical support is excellent. They promptly addressed my concerns regarding permission issues when I contacted them.

Positive

I used CentOS for non-enterprise purposes but switched to Red Hat for enterprise applications due to its superior support and stability. However, Ubuntu is generally preferred for Kubernetes deployments.

Red Hat Enterprise Linux is nine out of ten.

Red Hat Enterprise Linux does not require maintenance.

Our mid-size organization has between 20 and 50 employees, including our DevOps team, who use Red Hat Enterprise Linux.

I recommend Red Hat Enterprise Linux due to its support and strategy.

Red Hat Enterprise Linux (RHEL) is used to provide servers to our users. A specific example of a service provided using Red Hat Enterprise Linux (RHEL) is Apache reverse proxy servers.

In addition to providing Apache reverse proxy servers, we also manage a database server on Red Hat Enterprise Linux (RHEL).

I have been using Red Hat Enterprise Linux (RHEL) for 10 years. Red Hat Enterprise Linux (RHEL) is used to provide servers to our users. A specific example of a service provided using Red Hat Enterprise Linux (RHEL) is Apache reverse proxy servers.

In addition to providing Apache reverse proxy servers, we also manage a database server on Red Hat Enterprise Linux (RHEL).

I have been working in my current field for 10 years.

I advise others looking into using Red Hat Enterprise Linux (RHEL) to ensure you utilize the learning and training provided by Red Hat to get the most use out of it. I found that going through some of the certification process helped me familiarize myself with the features of the product.

For administering Linux servers, my main use case for Red Hat Enterprise Linux (RHEL) is focused on day-to-day tasks.

I used Red Hat Enterprise Linux (RHEL) on newly deployed on-prem VMs for the company I work for, which adds to my use case.

Stability definitely stands out to me as one of the best features Red Hat Enterprise Linux (RHEL) offers.

What makes Red Hat Enterprise Linux (RHEL)'s stability stand out for me is that I've noticed it's very error-prone, which I appreciate.

Since using Red Hat Enterprise Linux (RHEL) instead of Ubuntu, my organization has seen more stability in our infrastructure.

I noticed fewer outages and less downtime as specific outcomes since we began using Red Hat Enterprise Linux (RHEL).

I appreciate Red Hat Enterprise Linux (RHEL) the way it is right now, and I believe it can be improved but have no specific requests.

If I had to imagine one thing that could be even better about Red Hat Enterprise Linux (RHEL), it would be more information in the man pages.

I have been using Red Hat Enterprise Linux (RHEL) for three years now.

In my experience, Red Hat Enterprise Linux (RHEL) is indeed stable.

Scalability for Red Hat Enterprise Linux (RHEL) is excellent; it can easily grow with my organization's needs, making it easy to add more servers or resources as needed.

I have interacted with Red Hat's support team, and I find their customer support to be pretty much okay.

On a scale of 1 to 10, I would rate the customer support for Red Hat Enterprise Linux (RHEL) a nine.

Before switching to Red Hat Enterprise Linux (RHEL), we used Ubuntu, but we decided to make the switch because of stability.

I think Red Hat Enterprise Linux (RHEL) saved nearly 20 or 30% of our money, indicating a positive return on investment.

My experience with pricing, setup cost, and licensing for Red Hat Enterprise Linux (RHEL) was straightforward, without facing any challenges.

Before choosing Red Hat Enterprise Linux (RHEL), we evaluated SUSE, but we preferred RHEL for its more stable ecosystem.

My advice to others looking into using Red Hat Enterprise Linux (RHEL) is to examine its ecosystem.

My company doesn't have a business relationship with Red Hat beyond being a customer.

I was offered a gift card or incentive for this review.

I don't have any additional thoughts about Red Hat Enterprise Linux (RHEL) before we wrap up.

On a scale of one to ten, I rate Red Hat Enterprise Linux (RHEL) a ten overall.

The main use cases for Red Hat Enterprise Linux (RHEL) are all application-based; it's an enterprise-level OS based on open source. There are many applications. We are using it for Oracle databases and applications which need more security and flexibility. 

Red Hat provides support for a variety of file systems, making it easy to create and manage them. It also allows for straightforward management of volume groups. Although we have not used it for our client, Red Hat offers services such as Satellite service for online patching and automated patching, among other features.

The knowledge base offered by Red Hat Enterprise Linux (RHEL) is excellent. If you have an account created with even a single subscription, you get access to all documents available online free of cost. 

From the security perspective, IP tables are very important for firewall protection and network communication. While these features exist in other Linux distributions, the implementation in Red Hat Enterprise Linux (RHEL) is particularly robust.

Regular patching rollouts and immediate bug fixes help maintain compliance with cyber security requirements. 

All major Linux distributions should have common commands, which would make it easier for users to understand and remember. Each flavor has their own native tools and features, which can be confusing when managing multiple flavors in a single environment.

Documentation is comprehensive and available in one place on the Red Hat Enterprise Linux (RHEL) portal, but connection and integration could be better with more out-of-the-box connectors. 

Recently, I came across something interesting regarding the management of multiple environments. SUSE offers more flexibility in managing multiple environments, as their product can manage Ubuntu and Red Hat Enterprise Linux (RHEL). However, Red Hat Enterprise Linux (RHEL) Satellite server can only patch Red Hat and CentOS, not Ubuntu or SUSE. Cross platform support should be implemented in their product.

I have been working with Red Hat Enterprise Linux (RHEL) for almost 15 years.

It helps to mitigate downtime and lowers risk. Most environments have very high uptime values with Linux machines. Red Hat Enterprise Linux (RHEL) rarely crashes or has issues. All the security features are very good in Red Hat Enterprise Linux (RHEL).

The documentation clearly explains what each patching or update will do to your environment, and whether it is required. When asking for support, even for informational purposes, they provide detailed information about whether it is required for your environment, including bug fixes and CVEs reported by local cyber security personnel.

The business value of Red Hat Enterprise Linux (RHEL) compared to other Linux distributors is their strong support process. While we haven't worked much with other flavors, we are satisfied with Red Hat support. Their technical expertise is excellent, especially for premium support. They helped us solve critical issues, such as when we had a file system corruption in a production environment that we couldn't mount or fix without their support.

Positive

There are other options such as Ubuntu, SUSE, and Oracle Linux. It depends on requirements. Some application vendors want to go with Ubuntu, so we have to provision Ubuntu. Some want to have SUSE. SUSE is used less frequently, but mostly people are using Red Hat Enterprise Linux (RHEL) and Ubuntu here.

Ubuntu is a Debian-based Linux distribution. While all belong to the Linux category, Red Hat Enterprise Linux (RHEL) is more mature and flexible but costlier in terms of support. Ubuntu is less costly but has a different system administration approach due to being Debian-based. SUSE has more inclination towards ERP systems, with most SAP environments running on it.

Red Hat Enterprise Linux (RHEL) operates in a vast environment with multiple products including Ansible, containers, and OpenShift. System administration is straightforward in Red Hat Enterprise Linux (RHEL) because people are more familiar with these open source tools and commands. There is extensive online documentation and free versions available, making administration preferred by most administrators.

The setup is very straightforward. Even someone with minimal experience can follow the documentation and install it.

It brings ROI and measurable benefits. When support is needed for issues such as security vulnerabilities, ransomware protection, or bug fixes, Red Hat will resolve system downtime issues.

The licensing cost for Red Hat Enterprise Linux (RHEL) is comparable to SUSE for premium support. For approximately $2,000 per year, you can get premium support for one subscription which allows you to run two VMs.

I have not tried the Leap or Red Hat Insights feature because we currently work with standalone systems. For image builder and system roles, we can get the recovery system built with Red Hat Enterprise Linux (RHEL) tools, which are very good and handy for recovery.

Since most systems are based on VMs in private cloud or hypervisors, it's straightforward to take snapshots for any changes on Linux. If something goes wrong, reverting the snapshot is simple.

My advice to other organizations considering Red Hat Enterprise Linux (RHEL) is that while other enterprise Linux distributions such as SUSE and Ubuntu are good in their respective areas, they should have cross-environment support for products, especially for patching, centralized monitoring, and user management.

Based on my experience, I would rate Red Hat Enterprise Linux (RHEL) a nine out of ten.

The main use cases were certifying our product with this OS platform, installing our product on this platform, and identifying the challenges we face, such as memory leak issues or OS-level issues, such as some libraries not being supportive, permission-related issues, or glitches due to different folder structures because the paths vary from Windows. Developers mostly keep Windows in mind as they have Windows laptops for the development environment.

Most of the time, we only certify our product with this OS. We perform most of the operations related to that only, leaving very little chance to explore features. However, as I read the news and newsletter from the Red Hat side, there are a good number of features, such as server editions, that can be really helpful.

System roles are helpful because we can achieve security through them. This is a good feature, as we can restrict permissions and policies with their help. 

When interacting with terminals, most of the errors can be a bit complicated for humans to read. If they used more user-friendly error messages, it would help people understand quickly. 

There are also a few changes needed at the library level. Some libraries supported by others, such as Oracle, are not supported by Red Hat Enterprise Linux (RHEL). Especially in terms of Java, as now Java is with Oracle, if the Red Hat Enterprise Linux (RHEL) system could align with those libraries, it would be helpful for end-users, eliminating the need to figure out which library is causing issues.

I have been working with Linux solutions for four to five years.

It is stable.

We create a ticket when we contact Red Hat support, but most of the time, we are able to find solutions through the community. The support is good from both Oracle and Red Hat. I would rate their support an eight out of ten.

I have tried Oracle Linux and SUSE Linux, and we've explored different versions. It depends on the customer's requirement and whatever platform the customer is comfortable with; we have to certify our product with that.

There are multiple factors that led to our decision to move to Linux: pricing is one of the biggest factors, then security because Linux is more secure than Windows. Performance is another reason since malware programs do not run directly on Linux. Additionally, the command prompt is always faster than GUI mode.

When it comes to learning, it's all about perception because most people carry their perceptions from their college days. If someone is new or a fresher joining the industry, they have their own perceptions in mind. They often feel comfortable with Windows because most colleges provide Windows machines, but once they get hands-on experience with Linux systems, they start preferring Linux over Windows.

I haven't seen many complications with the initial setup of Red Hat Enterprise Linux (RHEL) because whenever we provide a build or our product, we have a readme file with all the steps included. It's usually not that difficult. It's a couple of hours of work, and if any difficulties arise, it doesn't take long because we have a good community online to find solutions.

I would rate Red Hat Enterprise Linux (RHEL) a nine out of ten.

I used it previously in environments for APIs, Apache Tomcat, and JBoss. 

The most valuable aspect of Red Hat Enterprise Linux (RHEL) is its reliability. The support is very good. 

The knowledge base offered by Red Hat Enterprise Linux (RHEL) is excellent. It is very easy to search for solutions to problems and apply new features. 

The main concern is the price. 

I used Red Hat Enterprise Linux (RHEL) for five years recently, and about ten to twelve years overall. The last time I used it was last year.

It's reliable. Red Hat Enterprise Linux (RHEL) did not help much with our uptime or security.

The support with Red Hat Enterprise Linux (RHEL) is good, and it is similar to Oracle. 

Positive

In the bank, we use Oracle Linux, but previously we used CentOS.

It was easy to manage in terms of provisioning and patching. We used other products to update the systems, though I don't remember the name. I had other teams to manage the environment. I was satisfied with the management process and the management experience.

It's expensive.

I would rate Red Hat Enterprise Linux (RHEL) a ten out of ten. I would recommend it to others. It is very stable.
