Red Hat Enterprise Linux (RHEL) Reviews

My use of Red Hat Enterprise Linux (RHEL) is for on-premise vertical solutions, but everything is on-premise. The main use cases for Red Hat Enterprise Linux (RHEL) include enterprise applications, such as databases and enterprise web applications, or security applications like WebSphere.

I find the most valuable aspect of Red Hat Enterprise Linux (RHEL) is its stability in working with other enterprise devices, such as firewalls and centralized storage. Enterprise applications and devices communicate well with RHEL, and it provides appropriate drivers for those enterprise devices. However, apart from that, I see almost the same performance with other open-source distributions like Ubuntu or Debian.

When assessing the knowledge base offered by Red Hat Enterprise Linux (RHEL), I find their documentation online to be excellent. I would rate the experience I have had with the documentation or knowledge base of Red Hat Enterprise Linux (RHEL) as excellent, giving it a ten out of ten. It is very good and useful for other Linux distributions as well.

The most important security feature in Red Hat Enterprise Linux (RHEL) is similar to that of other distributions, such as user creation and minimum privileges during the operating system's operation. In enterprise environments, I don't notice anything special in terms of security compared to others; it interacts very well with enterprise devices like firewalls and storage solutions.

RHEL has its own firewall, which is SE Linux, and I consider that to be a remarkable security feature. I have not tried Red Hat Insights; I don't know how to use that feature of Red Hat. Regarding the Image Builder or System Roles in Red Hat Enterprise Linux (RHEL), I haven't used them; I only use the ISO image directly for installation.

The solution has high pricing.

My overall usage of Red Hat Enterprise Linux (RHEL) has been uninterrupted. In total, it has been three years.

In terms of Red Hat support, I haven't used it, as everything I need to solve is in the documentation, which is very good.

I have previously used other solutions like Debian or Ubuntu.

I switched to Red Hat Enterprise Linux (RHEL) based on the direct requirements of the customer, not by my own decision.

The initial setup of Red Hat Enterprise Linux (RHEL) is straightforward; I find it very easy to set up.

My experience with the pricing, setup costs, and licensing of Red Hat Enterprise Linux (RHEL) indicates that this was the main topic that made me step away from RHEL. Personally, I don't see good benefits from their support and paid licensing compared to completely free and well-documented Linux distributions, as I find RHEL excessively expensive. Normally, the customer asks for a three-year licensing agreement for Red Hat Enterprise Linux (RHEL).

Overall, I would rate Red Hat Enterprise Linux (RHEL) as a nine technically, however, considering the cost, I would rate it a six, since it is very expensive. Combining technical and financial aspects, I give it a seven out of ten.

My main use case for Red Hat Enterprise Linux (RHEL) is running virtual machines. That's probably the most important use case for us.

Red Hat Enterprise Linux (RHEL) helps us solve pain points related to security. We want security, so it is hardened, and just supports us. As a financial institution we take security very seriously.

The feature I appreciate the most from Red Hat Enterprise Linux (RHEL) is support and simplicity. 

The knowledge base is good; they have a lot of documentation. 

We manage our Red Hat Enterprise Linux systems when it comes to provisioning and patching through Ansible. Everything's straightforward and efficient.

Adding more relevant features to Red Hat Enterprise Linux (RHEL) would be great. I have seen some issues on GitHub where people are suggesting things, such as Ansible. There are many community issues that could be implemented into Red Hat.

We try to stay two versions below the latest one just to make sure that we have security checked there and to avoid running into any bugs or issues with the latest release. We just try to apply patches as much as we can.

The stability and reliability of Red Hat Enterprise Linux (RHEL) are smooth as we have not encountered any problems or issues.

Red Hat Enterprise Linux (RHEL) scales perfectly with the growing needs of my company. It's easy to scale up with the tools we have.

My experience with the customer service and technical support of Red Hat Enterprise Linux (RHEL) has been amazing; they are very helpful. We open up a ticket, and we get someone to help right away.

Positive

The deployment is a smooth process. Some of the issues we have are just related to multiple vulnerabilities, and that's on our side to fix, however, everything else is smooth. We have no complaints.

The biggest return on investment for me when using Red Hat Enterprise Linux (RHEL) is how they have their foundation set. They have everything organized, documentation's there, it's globally used everywhere, and it's good software with good tools.

I'm not in the pricing conversation. I can't speak to costs.

Red Hat Enterprise Linux (RHEL) has helped me mitigate downtime and lower risks. They specifically thrive on criticism, and they don't take it lightly. They mentioned earlier in the panel that they wanted to prioritize the big CVs and any vulnerability that's important. Although some don't get exploited, it's good to have fewer of those numbers. 

We try to stay two versions below the latest one.

I would rate Red Hat Enterprise Linux (RHEL) overall an eight out of ten.

I have used Red Hat Enterprise Linux (RHEL) for most of my career. It is primarily used as the base operating system on which various applications run. Currently, I am attempting to transition away from RHEL due to changes in the organization following IBM's acquisition.

Red Hat Enterprise Linux (RHEL) is still considered better than Microsoft's offerings due to its superior handling of virtualization and faster performance. Microsoft often incorporates parts of RHEL's code, such as the networking stack, into its own products. The LEAP functionality for upgrades between versions is well-written and satisfactory.

RHEL has experienced a change in approach after being acquired by IBM, and the company has shifted away from open-source principles. The knowledge base is now outdated and lacks documentation for features in RHEL 9, relying instead on old documentation from RHEL 7. The introduction of unstable and undocumented products also detracts from the product's reliability.

I have used RHEL since it existed, so since 1991 or 1992.

RHEL has become less reliable due to undocumented updates and the release of unstable packages, which detracts from the product's stability.

Within the same vendor, moving workloads is easy. However, switching between vendors requires a significant migration effort.

The quality of Red Hat's support has declined in the past five to six years after outsourcing support to India. Complex issues are difficult to resolve due to communication challenges.

Negative

I have not switched from RHEL, but I am exploring alternatives such as Rocky Linux and Debian, which offer similar features without the high costs.

Setting up RHEL is quite straightforward, especially for someone familiar with it. The software asks the necessary questions for configuration, and the documentation generally explains these well.

The return on investment with RHEL is challenging to calculate but involves paying more upfront compared to Microsoft solutions for better reliability and stability, avoiding potential downtime costs.

The setup and licensing costs for RHEL are high, especially concerning support and associated applications. Red Hat charges high prices for support solutions like Ansible Tower, which can deter companies from using their products.

Other solutions evaluated include Ubuntu, Rocky Linux, and Debian. These alternatives offer similar functionality at a lower cost, especially concerning support.

Overall, I would rate Red Hat Enterprise Linux (RHEL) a seven out of ten. People are now turning to other Linux distributions due to RHEL's declining quality and high costs. I suggest caution when considering Red Hat due to the divergence from its original open-source model.

Our primary infrastructure operating system is Red Hat Enterprise Linux, predominantly RHEL Eight. While some products utilize RHEL Seven, RHEL Eight point Zero is the standard for most of our operating systems and servers. However, server choices may vary based on specific industry requirements. Our underlying infrastructure relies almost exclusively on Linux distributions.

Our primary Linux installations use Red Hat Enterprise Linux in an on-premises VMware environment, with some instances deployed on AWS.

The built-in security features simplify risk reduction by allowing direct control of the root system's access.

Red Hat's knowledge base is excellent.

While Red Hat Leapp and Insights are helpful tools, they are not part of my daily workflow.

The web console is a good feature.

Red Hat Enterprise Linux enhances uptime and security, boasting faster boot times than other operating systems.

The most valuable feature of Red Hat Enterprise Linux is its security, which is more secure than Windows. 

Integrating certificates from third-party clients into Red Hat Enterprise Linux can be challenging due to the operating system's stringent security policies.

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

Red Hat Enterprise Linux is stable.

Red Hat Enterprise Linux is scalable.

The technical support team was professional and quickly resolved our issue.

Positive

We use Oracle for our database, Ubuntu in our testing environment, and Red Hat Enterprise Linux in our production systems due to its increased stability.

The cloud migration from Red Hat Enterprise Linux Seven to Eight was straightforward due to the absence of underlying infrastructure complexities. However, the on-premises migration presented challenges from existing infrastructure dependencies, resulting in numerous errors.

The migration of approximately 200 servers required a team approach to ensure continuous monitoring. Although two people could have completed the migration, a four-person team completed it within two days. 

The migration from Red Hat Enterprise Linux Seven to Eight was done in-house.

Red Hat Enterprise Linux offers a compelling value proposition for corporations due to its robust support infrastructure, which is essential for maintaining enterprise-level systems. However, the pricing model may be less attractive to individuals or small businesses. Compared to cloud-based platforms like AWS or Azure, which offer flexible pay-as-you-go options, RHEL's subscription-based model can become cost-prohibitive for those with limited budgets or smaller-scale projects.

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

We utilize Ansible to provision and patch our extensive server infrastructure. Ansible's automation capabilities enable efficient batching and management of security patches across all servers.

We test all the patches for some time before we add them to our production environment.

We utilize Red Hat Enterprise Linux in our private cloud and on-premises environments, but I've observed better performance in the cloud, likely due to the greater availability of resources.

Red Hat Enterprise Linux does require maintenance.

Most of the applications I work with, including our primary enterprise-level application, necessitate the robust capabilities of an enterprise-grade operating system. Therefore, we utilize Red Hat Enterprise Linux to ensure optimal performance and stability for these demanding applications.

Red Hat Enterprise Linux is praised for its exceptionally precise documentation, which greatly aids in the learning and implementation process. Troubleshooting is straightforward, and solutions to any arising issues are readily available through a simple Google search.

For provisioning Red Hat Enterprise Linux, tools like Terraform and Ansible are commonly used to automate the process on a base machine. While Terraform handles various provisioning tasks, Red Hat provides its software for patching, although OpenSCAP is also a strong alternative for effective patch management.

Our organization uses Red Hat Insights, leveraging its user-friendly single dashboard to monitor all aspects of our systems. This centralized platform has proven invaluable for maintaining an overview of our infrastructure and ensuring operational efficiency.

We often use the Red Hat Enterprise Linux web console for things like viewing system performance and logs, managing user accounts, and configuring network settings.

Red Hat Enterprise Linux is robust, stable, and well-documented compared to the open-source versions of Linux.

I find the most valuable aspect of Red Hat Enterprise Linux to be its ease of customization. The operating system allows for the simple addition of kernels, modules, and other applications, making it highly adaptable to various needs.

Red Hat has several areas ripe for improvement. In the Asia Pacific region, where cost-optimization is highly valued, Red Hat's support and subscription costs are perceived as high and could be reduced. While their security documentation is comprehensive, some solutions lack open-source availability or training resources, unlike platforms such as Ubuntu. Furthermore, the quality of documentation and training sessions, particularly for OpenShift, could be enhanced. Addressing these issues would strengthen Red Hat's offerings and better serve its customers.

I have been using Red Hat Enterprise Linux for about nine to ten years.

Red Hat Enterprise Linux is extremely stable.

When Red Hat is involved in virtualization or OpenStack, moving from one virtualization platform to another becomes easier. However, when scalability is needed, it depends on the underlying infrastructure security, which is part of Red Hat import.

Communication quality is very good. I find very helpful people in the support section, and the Red Hat portal is robust for main solutions and support. When I receive support, I often find very interesting solutions.

Positive

I previously used CentOS, Ubuntu, and Debian, among other Linux distributions. However, with the growing popularity of containerization technologies like Kubernetes and Docker, solutions like Red Hat OpenShift are becoming increasingly common, particularly in regions like Bangladesh, India, and the Asia Pacific. That is why we are using Enterprise Linux.

The initial deployment and migration of Red Hat Enterprise Linux are straightforward, particularly for cloud-based solutions. However, on-premises migrations present a slight challenge due to the complexities of CVS solutions and potential application compatibility issues. This can involve numerous parameters that require careful consideration. My lack of experience with Red Hat's migration tools may have also contributed to the perceived difficulty.

Red Hat could gain a competitive advantage in the Asia Pacific region by adjusting its pricing strategy. Lowering the cost of enterprise-level offerings could attract organizations seeking operating systems or Kubernetes solutions, as these tools are essential for many businesses in the region. This adjustment would make Red Hat a more appealing choice compared to competitors with potentially higher pricing.

I have not found another operating system that matches Red Hat Enterprise Linux; it receives a perfect score of ten out of ten.

The Red Hat Enterprise Linux upgrade process is generally smooth. However, patching occasionally causes issues, typically due to application incompatibility or bugs in the updated packages. This necessitates restoring from a backup to maintain functionality. While this is a recurring problem, the infrastructure itself remains stable throughout the process.

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.

Positive

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.

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.

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.
