As a teacher, I have used Red Hat Enterprise Linux for server-side applications and containerization. My experience encompasses various system administration tasks, including managing servers, directories, data storage, files, and other related elements.

While teaching my students about Red Hat, I share my knowledge of system administration tools. This prepares them for Linux work environments that use Red Hat, exposing them to these tools and their applications. This also strengthens my organization's position as a Red Hat Academy, enhancing our sector's expertise. Red Hat is a valuable tool for learning system administration due to its widespread use and versatility.

In any Linux operating system, the patches come through, whether it's through long-term support solutions or community support. It's rapid overall. So when it's there, it's immediate and there's option to install and pass those updates.

The web console is beneficial as it provides an alternative method of accessing the operating system through a web-based platform, making it a valuable tool.

The hybrid environment, a relatively new infrastructure for us, offers flexibility and options. While there's always room for improvement, I find it exciting to have the choice between on-premises and cloud solutions. Although I'm still learning the nuances of this technology, it's been a positive experience so far.

Reliability is the most valuable feature.

Any form of technology always has areas for improvement, and Red Hat is no exception. They continually strive to enhance their products, evident in the frequent releases of new versions and updates to their operating system. Given that there is no perfect operating system, further development will always be needed. To facilitate this process, Red Hat provides support and encourages community involvement to identify and implement solutions that enhance its operating system's overall functionality, effectiveness, and user experience.

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

The initial deployment is complicated and requires up to two hours to complete.

While expensive, Red Hat Enterprise Linux offers efficiency and performance. Its commitment to ongoing improvements makes it a valuable resource for businesses seeking a reliable and cutting-edge operating system.

Red Hat Enterprise Linux is eight out of ten.

Regarding challenges, I've attempted to replicate the Linux environment using Red Hat, combining virtual Red Hat clients with third-party platforms to emulate a real-time atmosphere. One major hurdle has been motivating students to understand and utilize the system for these purposes. However, I've consistently found ways to overcome this challenge by using virtual machines and engaging in group discussions to explore the system's capabilities. I strive to emulate the real-time environment using my own systems, demonstrating the potential benefits and encouraging students to visualize how the system works in practice.

I'm using the Red Hat Platform with Open Stack and an RHEL product for storage. The use case is performance IOPS for Ceph Storage, which depends on a bare-metal RHEL server. 

For my security customer, we get greater than 90 percent uptime. RHEL helped us achieve security certification. It helped my end-user pass their security assessment. RHEL's built-in security features scan the third-party layer in the OpenStack and RHEL platform to assess the SSH and firewall security or patch updates from the RHEL platform and reset OpenStack. Security is the number one priority for my end user. They want to prevent hacker access from the outside. 

RHEL supports the hybrid cloud strategy. The goal of using a bare metal server has been to improve availability and database performance. The OpenStack platform uses network capability to improve database performance.

RHEL improves database and application performance for my end users. The application can collect regional and national data for my end user, a strategic customer in Indonesia.

I am confident in the managed services RHEL provides in terms of the OpenStack, Ceph Storage, and OpenShift container-based products. If there are any problems with the RHEL platform, Open Stack, Ceph Storage, etc., I can raise the issue to RHEL global support. 

For the past twenty or thirty years, Red Hat has reengineered its product from bare-metal on-prem to the cloud environment. Migrating an RHEL system from bare metal to cloud is somewhat difficult. They could add a fast boot. 

We deployed one side of RHEL in 2023, and we'll deploy the other side in 2025.

When I deploy RHEL for the first time, I try to learn about the performance and tune the performance. 

Scalability isn't an issue. Our customers haven't reported any performance problems from scaling up.

I rate Red Hat support eight out of 10. I have used Red Hat support since 2023. They escalate the ticket based on severity, and if they can't resolve the issue within the maintenance window, they will pass me to another engineer. 

Positive

We previously worked with Oracle Linux. My customer has two divisions. The network decision is focused on accounting database performance, while the IT division uses Oracle Linux. On the network side, the customer uses RHEL products like OpenStack, Ceph Storage, and OpenShift. 

My end user wanted to upgrade from RHEL OpenStack 16.1 to the latest 17.1.3 in April 2024. We also upgraded Ceph Storage and OpenShift. Now, my customer wants a testbed before upgrading to the RHEL version in live production. If there are problems, we open a ticket with global support and or two people will join our remote call. We have it deployed in Jakarta and plan to deploy it to Bandung.

I rate Red Hat Enterprise Linux eight out of 10. I recommend all the Red Hat products, including OpenShift and Ceph Storage. OpenShift Container is a mature product for RHEL portal customers.

The primary software utilized across our business units is S4HANA, which runs on our SAP server hosted on Red Hat Enterprise Linux. Consequently, most Red Hat systems in our environment support SAP-related services. We operate approximately 105 Red Hat Enterprise servers dedicated to running these SAP services.

Red Hat Enterprise Linux was implemented due to its robust infrastructure, which allows us to efficiently manage our enterprise servers on a large scale using tools like Red Hat Satellite, Insight, and Ansible. This centralized management simplifies the orchestration and control of our extensive RHEL environment. Red Hat Identity Manager also ensures secure authentication and authorization for our remote systems. Beyond infrastructure, Red Hat's robust support is invaluable, providing timely solutions to complex issues. The operating system's strong security posture, including rapid patch deployment for vulnerabilities, further solidifies our decision to implement RHEL.

Red Hat Enterprise Linux simplifies risk reduction by integrating Red Hat Insights. This provides a comprehensive security posture assessment of our Red Hat systems, offering easy-to-understand best practice recommendations and applicable actionable remediation steps.

The knowledge base offered by Red Hat Enterprise Linux is detailed and contains numerous articles that can help resolve our issues.

Red Hat Satellite simplifies our patch process by helping us meet audit and compliance needs. We've set up a lifecycle environment within Satellite to test patches on development and quality systems before deploying them to the operating system. This allows us to roll out patches based on the environment, ensuring thorough testing before reaching production. Additionally, we leverage Ansible automation to streamline provisioning and manage patches effectively. While automation is ongoing, we have successfully implemented Ansible and Red Hat Satellite for provisioning, and we continue to identify areas for further automation within our environment.

Red Hat Insights provides best practice recommendations based on regular system assessments. Like other security tools like Microsoft Azure Defender, it can access a system to offer security improvement suggestions. I have a Red Hat Insights certification and find the tool valuable. It generates actionable recommendations that can be easily implemented through automated processes like FastScript, making it an efficient way to leverage data insights for enhanced system security.

Since implementing Red Hat Enterprise Linux, we have experienced high performance, improved security, excellent support service, and easier system management.

Red Hat Enterprise Linux has enhanced our security posture through timely security patch releases and best practice recommendations, which collectively have increased the protection of our data systems.

Red Hat Enterprise Linux allows me to manage all my Cloud and on-premise systems from one console.

The most valuable aspect of Red Hat Enterprise Linux is its ease of management. A robust suite of tools, including the user-friendly GUI and the powerful Red Hat Cockpit web portal, simplifies system administration. Cockpit provides a centralized platform for managing hosts, while Red Hat Satellite or automation servers excel at overseeing large fleets of radar systems.

Red Hat Enterprise Linux training and certification opportunities for engineers and administrators could be improved. While I have benefited from free training offered by other companies like Microsoft, I have not had similar opportunities with Red Hat. Despite holding a Red Hat certification, I incurred significant costs to achieve it. The training required for these certifications is expensive, and it would be advantageous if Red Hat provided more affordable training courses.

I have been using Red Hat Enterprise Linux for seven months.

Red Hat Enterprise Linux is highly stable.

Red Hat Enterprise Linux is scalable.

The support is good.

Positive

I have used Ubuntu Linux, Windows Server, and other solutions. Compared to these alternatives, Red Hat Enterprise Linux stands out as superior in terms of ease of management, security, and support.

The initial deployment is straightforward. Deploying it manually takes about fifteen to twenty minutes from start to finish using it manually.

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

We have 15,000 users all across Africa that use our systems.

Red Hat Enterprise Linux requires periodic maintenance to apply security patches and updates.

I recommend Red Hat Enterprise Linux and conducting a proof of concept to ensure it aligns with our requirements.

I use Red Hat in data routines for web, database, and container servers. Right now, I'm using three primary use cases.

Red Hat offers compliance consulting services. If we purchase hardware from companies like HP, Dell, or IBM, which also partner with Red Hat, they often guarantee compliance for their hardware. This compliance can extend to security regulations imposed by certain countries or governments, such as those based on NIST or CSSP standards. Red Hat's focus on compliance seems to center primarily around these hardware-related aspects and associated security requirements.

Red Hat's knowledge base requires an active subscription for full access, but developers can utilize a free, annually renewable option. With an activated developer subscription, users gain access to forums, documentation, the latest news, vulnerability reports, and other resources related to Red Hat Enterprise Linux and its associated packages. The knowledge base is now well-documented, and the active community quickly responds to forum inquiries, often within a few hours.

Leap is a feature designed by Red Hat to migrate its operating systems between versions. Introduced to address the end-of-life issue for distributions like CentOS seven, eight, and RHEL seven, eight, Leap allows users to upgrade from RHEL seven to eight, RHEL eight to nine, CentOS seven to eight, and CentOS eight to nine. However, Leap is specifically designed for Red Hat and works optimally only on Red Hat seven, eight, and nine. It does not function as intended on CentOS, Fedora, Oracle Linux, or other community distributions. Red Hat Insights is a complementary tool that provides valuable information to subscription holders about their licensed servers, including package installations, subscription validation, detected bugs, and vulnerabilities. It also offers alerts about new vulnerabilities and patches and facilitates license management and environment oversight.

I've used Convert2RHEL, a tool that simplifies transitioning from CentOS-based distributions like Leap to Red Hat Enterprise Linux. It supports converting only CentOS to RHEL by replacing binaries and installing Red Hat logos. Underlying Ansible scripts entirely handle this process. While I've had success with it, occasional minor issues arise but are easily resolved.

I have experienced minimal downtime while using RHEL. Some of our RHEL systems have operated uninterrupted for over 600 days. The only necessary reboots occur when applying kernel updates. Overall, RHEL has demonstrated reliable and resilient uptime and security.

Due to its built-in compliance features, RHEL is instrumental in achieving certifications for security standards. The system incorporates policies that align with regulations for governance and public institutions. When installing Red Hat Enterprise Linux in the cloud or on-premises, users must implement security policies that activate specific plugins and APIs to maintain compliance. Given its comprehensive coverage of contemporary compliance standards, Red Hat is the most valuable distribution.

Release updates are the most valued feature because Red Hat's rigorously tested release update pipeline sets it apart from other distributions. While many options are available, none match Red Hat's commitment to thorough package testing. Packages are initially delivered to Fedora, Red Hat's community distribution, for testing and validation. Proven packages then transition to CentOS, and after six months, the most stable and reliable packages are incorporated into the new Red Hat release. This well-defined pipeline ensures that Red Hat packages are stable and long-lasting. However, not all packages released in Fedora make it to Red Hat; some experimental or community-driven packages may not meet enterprise standards. Fedora serves as a testing ground, while Red Hat focuses on delivering a stable operational system.

Red Hat, known for its secure distribution, sometimes delays critical security patches for certain packages compared to other Linux communities like AlmaLinux or Rocky Linux. For instance, AlmaLinux addressed recent vulnerabilities in the SSH package within days, while Red Hat took over a week to release a patch. While Red Hat's rigorous testing ensures high-quality patches, the delay in releasing them can pose security risks.

Red Hat Enterprise Linux is a highly regarded but expensive distribution known for its top-notch software. This high cost often precludes smaller companies from adopting it. There is potential to make Red Hat Enterprise Linux more accessible to a wider range of businesses by lowering the price.

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

I previously encountered instability with an assistant. While using a non-Red Hat graphical interface, KDE, I experienced a system crash following a kernel update. This desktop environment proved incompatible with the new kernel. Conversely, servers utilizing only the command line never suffered crashes or downtime. I've observed the opposite trend in my Red Hat infrastructure, demonstrating exceptional resilience. For instance, during a complete data center outage two or three years ago, Red Hat systems recovered within minutes, while Ubuntu servers required significant maintenance. This suggests that Red Hat offers greater stability and reliability in our environment.

Specific features such as path movement and load balancing must be enabled when running routes within a cluster. Pre-installed software simplifies the process for system administrators to implement smart clusters and scale servers. Among various distributions, Red Hat is considered the most proficient in these areas, excelling in scalability and cluster server management.

The deployment was challenging, not because of Red Enterprise Linux itself but because the application runs within this distribution. Certain legacy software required manual installation on this new system, which complicated the migration process. However, the operating system itself is straightforward and plug-and-play. The difficulties arose from configuring the necessary applications within the distribution. I've had no issues working with or migrating to this distribution.

Red Hat Enterprise Linux is only affordable for large organizations.

If I had to choose alternatives to RHEL, I would consider Oracle Linux and AlmaLinux. Oracle Linux is an enterprise distribution based on Red Hat, offering binary compatibility, meaning applications built for Red Hat Linux will run identically on Oracle Linux. It is an enterprise-grade product without the associated costs, as the distribution itself is free, with charges only for optional support. While I believe AlmaLinux is more resilient and reliable than RockyLinux, my preferred alternatives would be Oracle Linux first, followed by AlmaLinux.

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

Cockpit is a technology offering a web-based console for server management. This web console can also perform any action achievable through the command line interface. However, I do not recommend it due to the inherent security risks of running a web server, especially when managing another web server. This introduces additional vulnerabilities and necessitates increased patching efforts. My preference is to maintain a minimalist system that runs only essential services. While Cockpit might be suitable for junior system administrators in the RHEL environment, as a senior administrator, I exclusively utilize the CLI, both on-premises via SSH and in cloud environments. I would only consider implementing Cockpit if we have junior staff and are willing to implement robust security measures such as firewalls, access control lists, and other protective strategies.

I used Red Hat Enterprise Linux to construct systems according to the application team's requirements. I build and support these systems through the development, testing, pre-production, and production phases, fulfilling both developer and operational roles. To ensure the systems can handle the application's demands and meet our cybersecurity standards, I implement all security measures outlined by our cybersecurity team.

The extensive knowledge base offers a full path from beginner to advanced levels. We can access everything needed to study, pass exams, and apply knowledge immediately. The information is presented clearly, without any abstract concepts.

Red Hat offers built-in security features that simplify risk management. Unlike Oracle Linux, which overlooks critical security features like C Linux, Red Hat actively develops and maintains robust security measures. As a result, Red Hat prioritizes system security, consistently providing updates to fortify its machines against potential threats.

Red Hat helps us maintain compliance by enabling us to create and modify firewall rules as needed, allowing for strong security measures that can be adjusted.

The security reports generated every three months are valuable for provisioning and patching as they identify vulnerabilities requiring remediation. I find all the necessary information to address these vulnerabilities and implement patches through the Red Hat Enterprise portal and community resources.

When I started using Red Hat Enterprise Linux five years ago, I noticed the benefits incrementally over time.

Red Hat's greatest asset is its extensive community, which provides valuable support and advice when issues arise. Due to the robust nature of this community, I have never required direct assistance from Red Hat Enterprise.

Red Hat offers customizable tools, such as Assemble, that enhance flexibility within enterprise products. Assemble is a platform capable of managing multiple systems from a single console.

While Red Hat offers essential starting and security documentation, I would like to see it officially recognize the more detailed and customized documents available in the community and make them accessible on its website.

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

Red Hat Enterprise Linux is the most stable system I have ever worked with.

Red Hat Enterprise Linux is scalable.

I changed jobs five months ago, and my new company uses Oracle Linux instead of Red Hat, so Oracle provides support rather than Red Hat.

I find Red Hat Enterprise Linux more flexible, with a larger community and numerous security advisors.

We found it less complex to build a new system on the newer version of Red Hat Enterprise Linux and migrate data rather than upgrading the existing system from, for example, version seven to eight. A simple upgrade risks data loss.

One person can do the upgrades and migrations.

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

The system requires immediate maintenance due to necessary security patches, unresolved vulnerabilities, and a constant influx of operational tasks from other teams. These daily demands include critical adjustments such as modifying service ports and implementing local firewall rules.

I recommend new users visit the official Red Hat Enterprise Linux website to review the guides, explore the community, and research information related to their Red Hat Enterprise Linux tasks. 

We use Red Hat Enterprise Linux to maintain our systems, manage our user logs, and monitor our storage.

The fact that Red Hat Enterprise Linux is stable has led to more enterprises wanting to use it. All the updates are current from a security point of view. So, the fact that we are one-managed or subscription-managed through Red Hat Enterprise Linux keeps us secure.

Red Hat Enterprise Linux's built-in security features simplify risk reduction and help maintain compliance, which gives us peace of mind.

The knowledge base of Red Hat Enterprise Linux depends on the end user. However, the information is always there, and the most reliable information is from the Red Hat system.

We have a dedicated server for provisioning and patching, and I am satisfied with how it works.

Red Hat Enterprise Linux's Image Builder and System Roles improve our productivity by increasing efficiency.

The Web Console is helpful because we use it to monitor and record users if we choose to, as well as check our system to make sure everything is up to date and we are current with the latest patches.

Red Hat Enterprise Linux helps us be more compliant.

Red Hat Enterprise Linux's ease of use in a controlled system, especially when dealing with constant repository updates, is valuable.

From a monitoring standpoint, we have Splunk, which is more versatile in monitoring data files, and Nagios, which can monitor multiple instances via Windows or Linux servers and different boxes. If Red Hat Enterprise Linux can improve its monitoring capabilities, that would be helpful.

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

Red Hat Enterprise Linux is stable.

I have not submitted any support tickets because we can find all the answers we need from the RHEL community for minor issues.

Positive

Red Hat has been the industry standard for most companies, but sometimes, organizations will run a Windows server and Active Directory alongside it.

The critical difference between Red Hat and Windows lies in their user interfaces. While both share a similar underlying structure, Windows offers a graphical interface for easy interaction, while Red Hat relies on command-line prompts. This makes Red Hat a more secure environment.

Red Hat Enterprise Linux helps improve efficiency, reducing vulnerability and, ultimately, a higher return on investment by minimizing IT costs and downtime.

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

We have between 100 and 200 end users. Red Hat Enterprise Linux is deployed in a standard, dev, quality, staging, and production environment.

Maintenance is minimal for Red Hat Enterprise Linux. We only deal with updates and patches.

We use Red Hat Enterprise Linux to run Oracle Databases for CC&B and JDM. All the RHEL stuff is on-prem. The CC&B team manages the customer care and billing stuff, but we take care of the operating systems, and the application users manage the applications. We have 200 to 300 users on RHEL. 

We are missing random devices for patching and everything, and we don't have the Linux data license for that. If we had that, life would be much easier. Right now, we patch using Yum updates and we manually do configuration changes from our end.

Red Hat Enterprise Linux improves our security. On our end, we only use the console to reboot the server and apply security. We patch it completely if we have any security updates. Every quarter, we run a report using quality and whatever it was pulling. That's what we are patching. 

Red Hat Enterprise Linux makes patching and scripting much easier, and it provides all the features I need for patching and VM updates. It's easy to apply Red Hat Enterprise Linux's built-in security features when it comes to simplifying risk reduction or maintaining compliance.

For phone support, we had to buy a license for all our servers, and it was a bit pricey for us. 

I have used RHEL for 21 years.

Red Hat Enterprise Linux is highly stable. We've never had any problems or crashes. It's very smooth from our end.

It's easy to scale Red Hat Enterprise Linux. Right now, we're discussing what will happen a year from now, when we plan to increase our usage. 

I rate Red Hat customer service eight out of 10. Their knowledge base is fantastic. You can easily find whatever you need. Their support responds immediately, whereas we struggled with support from Oracle. 

We were using Oracle Linux, and I don't see much difference except the support. We were not getting good support from Oracle because it took too long whenever we opened a ticket. Oracle was also too expensive, and patching is much easier with Red Hat Enterprise Linux. We were not looking for more features. Oracle Linux has a lot more packages than we need.

Setting up Red Hat Enterprise Linux was straightforward. You need at least two system admins to do so. Migrations and upgrades are also easy. Our main products are CC&B and JDM, with an Oracle database on the back end. We were highly satisfied with Red Hat Enterprise Linux for migrating all of those. We also have other solutions like SQL Server, which is on the Windows operating system.

Performance-wise, this Linux is better because you can ignore some packages if you don't need them. 

Oracle Linux is free, but we were having many other issues with it.

I rate Red Hat Enterprise Linux nine out of 10. Red Hat Enterprise Linux is very easy to install and manage. 

I use Red Hat Enterprise Linux as an operating system for government contracts. 

I like the flexibility Red Hat Enterprise Linux offers in terms of permissions. The patch management is much shorter and easier. Red Hat Enterprise Linux helps us move workloads between different clouds and data centers. It's pretty smooth and transparent. 

We use AMIs — machine images — for provisioning. The image builder is nice. It's a vertical Amazon machine image. They have each machine image, so you don't need to install anything. You can just copy the machine image. 

There's an operating system called EdgeOS, which is an edge operating system used by edge computing nodes in the cloud. If Red Hat Enterprise Linux had a version incorporating EdgeOS-type functions, that would be great. Otherwise, you have to learn a little bit of EdgeOS to work with those nodes.

We have used Red Hat Enterprise Linux for several years.

I rate Red Hat Enterprise Linux nine out of 10 for stability. 

I rate Red Hat Enterprise Linux nine out of 10 for scalability. 

I rate Red Hat support nine out of 10. 

Positive

Red Hat offers better support and stability. There are several others, including Windows, and Red Hat Enterprise Linux is a pretty stable standard operating system. 

I rate Red Hat Enterprise Linux nine out of 10 for ease of deployment and migration. Deploying an AMI is straightforward. We hardly had to do anything. It's pretty much automatic and uninterruptible. 

I wasn't involved in the licensing, but Red Hat Enterprise Linux's price should be reasonable if the government and others get it. 

I rate Red Hat Enterprise Linux 10 out of 10. It's the top of the line.
