As a system administrator, I specialize in building infrastructure on Red Hat Enterprise Linux, with a focus on automation from initial design through to implementation.

Red Hat Enterprise Linux has significantly helped our company grow by enabling automation, allowing us to provide multiple services simultaneously and reduce repetitive tasks through the creation and sharing of solutions with other teams.

Red Hat Enterprise Linux enabled us to centralize development.

Ansible is one of my most-used tools, and I especially appreciate its automation capabilities.

While Red Hat Enterprise Linux offers many valuable features, some, particularly the latest ones, are not immediately available until deployed on-premises. Additionally, although I need to become fully acquainted with its built-in security features, the dashboards could be enhanced to provide more comprehensive security insights.

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

Red Hat Enterprise Linux is stable. I've never had any problems with its stability.

The scalability of Red Hat Enterprise Linux is.

The customer support and technical support are good. Normally, I can find my own solutions and if not, I can reach out to the vendor for assistance.

Positive

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

We face restrictions in accessing the latest features for various tools, including Elastic and Red Hat. For instance, we cannot utilize certain Elastic features because they are not publicly available. Similarly, with Red Hat, we must wait for the newest features to be released on-premises before we can access them. This limitation hinders our ability to leverage the most up-to-date technology.

The key advantage of Red Hat Enterprise Linux over other open-source Linux distributions is its comprehensive support, which includes access to updates, security patches, and technical expertise.

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.

Streamlining the packaging process would enhance efficiency and ease of use for administrators.

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

Red Hat Enterprise Linux is a stable platform.

Red Hat Enterprise Linux is highly scalable. By adding more hosts and doubling the number of VMs, it has successfully worked for our needs.

Technical support responds quickly to urgent issues, but minor bugs may take a considerable amount of time to resolve.

Neutral

Our projects utilized various solutions, including XLD and UCD, as well as some legacy technologies. Red Hat Enterprise Linux proved easier to configure than previous platforms, offering greater flexibility and alignment with current best practices.

While I lack direct deployment experience, I understand that Red Hat Enterprise Linux facilitates straightforward modifications, minimizing concerns about system disruptions.

Red Hat Enterprise Linux offers the greatest return on investment through its invaluable support, which is crucial for our critical applications. The comprehensive documentation and extensive resources, including Q&A and solutions to previous issues, are also essential.

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

Red Hat Enterprise Linux offers robust built-in security features that help with risk reduction, business continuity, and compliance. However, hosting external tools within a bank environment can create challenges in synchronizing policies and meeting security expectations. Ensuring the tool's security configurations align with the bank's server requirements can be complex, but this challenge is not unique to Ansible and is a common issue when integrating external tools into secure environments.

Red Hat Enterprise Linux offers greater control and a higher level of security compared to some open-source alternatives, which can be crucial for enterprise applications where stability and reliability are paramount. This focus on security is a key factor in choosing Red Hat Enterprise Linux.

We have a multitude of use cases for Red Hat Enterprise Linux within our organization. We have machines running this operating system, and in our landscape, we also have combined database services.

We are currently using it on-premises but have a roadmap towards a hybrid cloud solution. Because of the way our business operates, it is something that we utilize only on-prem currently.

They are a technology enabler for us. It is a part of one of the core functions in the organization, where the operating system supports running various services, not just on devices but also SQL-based services and applications. They are definitely a technology-enabling organization for us. 

We have the ability to manage all of our infrastructures in one area. The support is also there. We utilize it in our organization due to the fact that it is very good.

The regular updates and fixes from them for vulnerabilities help with risk reduction. To maintain compliance, we have a relationship with the vendor. They assist us in making sure that we have all our vulnerabilities covered. From a business continuity perspective, we make sure that we use the technology to its best capability.

Red Hat Insights provides vulnerability alerts and targeted guidance. It definitely minimizes your downtime. You have more proactive monitoring than reactive monitoring. A lot of the tools out there only give you the capability to handle something that has already happened. This is something that enables you to be more proactive and do your patch management for security vulnerabilities and so forth.

The high availability capability and the support functions we get from Red Hat Enterprise Linux are among the most valuable features. 

Also, Red Hat Insights is a key feature. You have a central view of all of the infrastructure in the organization. It is definitely something that other organizations need to invest in. It also streamlines things. You have the capability to have reporting, insights, and other things within one space.

One area for improvement could be moving towards a more agile DevOps way of working. Other technologies out there have enabled agile and DevOps practices, and this is something Red Hat Enterprise Linux could focus on. 

Our organization has been using Red Hat Enterprise Linux for quite a few years. Following LCM, we always stay up to date with the current version.

Red Hat Enterprise Linux is definitely stable.

It definitely has scalability from an up-and-side perspective.

Customer service and support are very good. We can always rely on them to assist when we run into issues. I would rate them a ten out of ten.

Positive

We have multiple operating systems in our landscape, but Red Hat is most likely the leader as an open-source solution. The choice of a solution comes down to fit for purpose. Red Hat Enterprise Linux fits our purpose.

The biggest return on investment is reliable support, as we can always rely on them to assist with any issues.

In terms of total cost of ownership, it is definitely something for which you have to work with the vendor and ensure that you have a cost-effective solution in place.

I work closely with the licensing department in determining licensing costs and requirements. Pricing is something that needs to be worked out with the vendor. The more you have, the less you pay. That is the model nowadays in IT, but it is very cost-effective. You get what you pay for.

When choosing a solution, it is crucial to ensure it is fit for purpose. There is a reason why you pay for support. At the end of the day, it comes down to the support that you get from the vendor.

We do not utilize the containerization part, but definitely, in the future, we will move to a hybrid way of working. Everyone is moving to more of a hybrid cloud solution these days rather than having it only in the cloud or on-prem. Red Hat Enterprise Linux supports working in a hybrid environment. It is definitely an enabler.

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

We use Red Hat Enterprise Linux for our infrastructure, and in recent years, we have also been using it for Ansible, primarily for appliance deployment on the customer side.

Red Hat Enterprise Linux is deployed on-premises on our virtual machines.

Red Hat Enterprise Linux provided our organization with increased stability over the past decade.

Red Hat Enterprise Linux has allowed us to centralize development and focus on our projects by providing a consolidated platform for our enterprise distribution.

We are satisfied with Red Hat's built-in security features, which effectively reduce risk, ensure business continuity, and maintain compliance. Red Hat Enterprise Linux provides a more secure operating system than other Linux solutions due to its robust security features and a supported kernel that receives regular security updates.

Red Hat Enterprise Linux, when used with Ansible, has significantly automated various tasks, leading to a reduction in the total cost of ownership.

It has helped save the organization costs.

I find the most valuable aspect of Red Hat Enterprise Linux to be its comprehensive support, encompassing both technical and security issues.

Red Hat's comprehensive documentation eliminates the need to contact technical support for any issues encountered.

The deployment learning curve for Red Hat Enterprise Linux could be more user-friendly.

I have been using Red Hat Enterprise Linux for 14 years.

Red Hat Enterprise Linux offers exceptional stability, with downtime limited to scheduled maintenance periods.

Although Red Hat Enterprise Linux is designed for scalability, our current deployments are not large.

Our organization has always used Red Hat Enterprise Linux.

Deploying Red Hat Enterprise Linux can be challenging, but the documentation provides valuable assistance.

The implementation was completed in-house.

Red Hat Enterprise Linux offers a significant return on investment through Ansible, a powerful tool that enables the automation of our environment.

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

Red Hat Enterprise Linux distinguishes itself from other vendors by offering exceptional support and ensuring that organizations have readily available assistance when needed.

Red Hat Enterprise Linux is the industry standard compared to other Linux vendors.

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

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

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

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

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

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

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

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

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

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

Positive

The initial setup is smooth.

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

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

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

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

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

The primary use case for Red Hat Enterprise Linux is automation. We have Ansible running on some Red Hat Enterprise Linux servers, and a lot of it is geared towards automation. We have the automation of processes like patching, upgrades, OS enhancements, or OS upgrades. Additionally, our stores run on Red Hat Enterprise Linux.

Red Hat Enterprise Linux is pretty secure, but we rely on our network products to handle a lot of our security. We have Cisco products. These servers that we are currently running are not necessarily tightened down on the ports, traffic, etc. We rely on Cisco firewalling to handle a lot of the traffic, load balancing, and so forth. I have not configured a lot of security per se right on the server itself at a kernel level.

I like the knowledge base. They have a pretty good knowledge base portal. On their website, they have a lot of great classes. I do appreciate doing that. I have taken several myself, so I am pretty impressed by that.

We use Ansible Playbooks for patching our devices, especially those that are out in the field. We are using Ansible Playbooks to handle patching. We are using the systemctl command that goes into the repos to grab whatever patches we need. So far, the management experience has been good.

I have used a lot of different Linux distributions, and one thing that I like about Red Hat Enterprise Linux is the support. The support from Red Hat is very good. They offer excellent customer and vendor support. 

The ease of training is great, and I appreciate products like Ansible Tower. 

Its interface is good. It is a very solid operating system.

Some of the documentation that I have run into or encountered appeared to be a bit outdated. That would be an area for improvement.

I have been using Red Hat Enterprise Linux since early 2000. It has been about 20 years.

Red Hat Enterprise Linux is very stable. I have not experienced any instances of crashing with the Red Hat servers that I have worked on.

Other than the issues with the legacy software or some of the IBM AS/400 that we tried to add to it, it has been pretty seamless. Building them out and migration to the data center or the VMware environment has been pretty seamless. 

Customer service is great. We use a support portal to open a ticket, and the response time is good. We usually get an email response or an update to the ticketing system, and then if necessary, we get a callback within four hours. The response time also depends on the priority. If we are looking at a massive data center outage, I am sure it is a priority one. Most of the tickets I submitted took one to four hours.

Positive

I have used SUSE in the past. They have a pretty good support system. They have got a good OS. I am not sure what the market share is for those guys, but they are pretty good.

Our environment is a combination of the cloud and on-premises, but we primarily use Red Hat Enterprise Linux on-prem. We have a few development test servers running on Azure. They are not used in production. They are just for testing.

I was involved with the migration from SUSE to Red Hat, but that was close to a decade ago.

From what I recall, the initial setup was not that difficult. We did have some engineers from Red Hat who came out to help us. It would have been more difficult if we did not have them there, but from my recollection, it was not very challenging or difficult. We were able to get that done pretty quickly. There were some issues with legacy software, but those applications were built on the Windows platform. They were a little bit of a mess. Other than that, it appeared to go pretty smoothly for us.

It does not require much maintenance. Other than patching and keeping up with bulletins as to what might be out there, there is not much. There is not a huge amount of maintenance. They run pretty solidly. The uptime is great. I do not have to restart a lot of these servers. I might have to restart a service here and there, but nothing that I can remember.

We had help from Red Hat engineers during the implementation.

Red Hat Enterprise Linux provides a much more secure and stable system than Windows infrastructure, and the support is also great. Of course, you pay for the support.

We were able to see its benefits after some time. Some of the returns are seen after a while, not immediately. Sometimes, migrations might be difficult to do if you are running legacy software.

I am not involved in the budgetary aspect, but from what I understand, the pricing is competitive, similar to what we paid for SUSE.

Having a solid foundation in Linux can be very helpful. Learn as much as possible. Automation has become a very important part of the industry now. Learning how to automate with Ansible, Kubernetes, Docker, and Python along with Red Hat Enterprise Linux should set you up for success.

We have not tried Red Hat Enterprise Linux Image Builder or System Roles. Image Builder sounds good, but I have not tried Image Builder. We build our images from vCenter. Image Builder would definitely be something to check out.

Using it in a hybrid environment is a very interesting concept, where we keep some of the hardware and applications on-prem and then maybe rely on Red Hat to handle some of the networking or other configurations externally. I would like to try that hybrid approach.

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

We use Red Hat Enterprise Linux as our server operating system to install and configure various applications. Its uses include system troubleshooting, DNS configuration, and many other tasks, especially in a mixed environment with Ubuntu.

Patching Red Hat Enterprise Linux in our environment is a straightforward process that utilizes Red Hat Satellite. We identify necessary patches for production servers in the content view and notify customers two days in advance via email. Before patching, we verify the Nagios servers for identification purposes. We then execute a pre-configured Ansible playbook to efficiently patch our 300 servers. This playbook was already established, and our only interaction with it is to run it.

The web console is handy, especially for tasks like command line operations. Its secure environment allows for the safe execution of queries.

Red Hat Enterprise Linux is most valued for its reliability, as evidenced by my daily use.

The documentation needs improvement. Providing more detailed explanations would make it easier to work on projects.

I have been using Red Hat Enterprise Linux for my entire career, which spans over eight years.

Red Hat Enterprise Linux is stable. There has been no significant issue regarding lagging or downtime.

Red Hat is highly scalable and essential in the industry. I would rate scalability nine out of ten.

The customer support from Red Hat is good. They are always there to help when needed.

Positive

I have used Ubuntu, and Kali Linux alongside Red Hat.

I have been involved with migrations to Red Hat Enterprise Linux, which are not complex. For example, migrating to Red Hat Enterprise Linux 7 or 8 is easy, requiring only the installation of necessary dependencies and the creation of a file to sync files to the new system.

I typically work as part of a team rather than implementing integrations on my own.

Red Hat Enterprise Linux is quite expensive, particularly its technical support, which can cost $500 per hour.

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

Realizing the benefits of Red Hat Enterprise Linux took time, as post-deployment troubleshooting was often necessary. This included tasks like opening ports and verifying functionality, which were sometimes prerequisites for the system to operate. These requirements varied depending on the specific application used and its security needs.

We perform maintenance on Red Hat Enterprise Linux every weekend, including backups. Incremental backups are done daily, while full backups are completed every weekend.

We use Red Hat Enterprise Linux in the enterprise for production environments. We mostly use it on bare metal servers, which are dedicated. In terms of deployment, we use the on-premises version of Red Hat Enterprise Linux.

Red Hat Enterprise Linux has given us better insights and allowed us to manage the environment more effectively. In terms of overall performance improvements, it has provided us with increased visibility into security, which has been helpful for our cybersecurity team.

Its built-in security features seem pretty sufficient for our purposes, but we have other teams that manage the security and build aspects. I am more involved in the maintenance of it, but in terms of the built-in security features, I find it sufficient. The security team also takes care of the compliance aspect.

I mainly use the Red Hat database for vulnerabilities. It is pretty good for determining whether or not a vulnerability has been resolved. 

We use Red Hat Satellite for patching. I like Red Hat Satellite for patching and keeping us secure.

We have used Red Hat Enterprise Linux in hybrid environments. It seems to work fairly well. For hybrid environments, it is probably one of the easier ones to deploy because it allows us to scale.

We were able to realize the benefits of Red Hat Enterprise Linux immediately after the deployment.

In terms of the organization and structure, the support is on point. The reporting and other things are very standardized. It does not leave much room for error when working in production environments.

When we first deploy Red Hat Enterprise Linux, it is very challenging to determine which security features have been deployed. It would be beneficial to have more insight into this. Additionally, once it is built, there does not seem to be an option to retroactively change security features, which can make it difficult to ascertain which ones have been deployed.

Their knowledge base is very verbose. There is too much information. It can complicate things a little bit. It is very detailed. If they can shorten it, that might be helpful.

We have been using Red Hat Enterprise Linux for a few years now, approximately seven to eight years.

I would rate the stability of Red Hat Enterprise Linux as seven out of ten. We do encounter problems, most of which can be resolved. Occasionally, we face issues that cannot be resolved until the kernel developers address them. These are typically dealt with through quarterly releases or major upgrades.

In terms of scalability, I would rate Red Hat Enterprise Linux about a nine out of ten. It is easy for us to make snapshots when we are patching. If we need to clone, we can do so, although they might not be full backups necessarily.

We use their portal for contacting support. The support from Red Hat is quite quick because it operates on a service-level agreement (SLA). For the paid support features, they are very responsive.

Positive

I am familiar with CentOS, and I have used OpenSUSE and SUSE Enterprise for testing and comparison purposes.

CentOS did not have as many security features. Of course, CentOS had the community support. CentOS was bought by Red Hat, and then the support started lacking. It was then discontinued to promote Red Hat Enterprise Linux.

We have done some physical to virtual migrations using VMware. We have been mostly involved in that. We have done a little bit of virtual-to-cloud migration but not as much as physical-to-virtual.

The migration is more on the complex side. There are quite a few players involved. We need to collaborate with different teams. We need to make sure that the database is there, and that the database team is always involved. It is not terribly simple. It requires quite a bit of project planning and coordination. We usually have a six-month project so that it can be planned and tested.

It does require maintenance on our end but not very frequently.

Red Hat Enterprise Linux licensing is quite costly, but I personally do not deal with pricing.

My advice to new users would be to focus more on the build aspect because it can be overlooked by many new users.

The Leapp utility works well when you do not have a much-customized environment. The more customized your environment is, the more complicated it gets to get Leapp to work to switch over to Red Hat Enterprise Linux. It is possible, but the more customized your environment is, the harder it is because it will require the kernel module. Convert2RHEL is pretty much the same as Leapp. The more customized the environment, the harder it is. It is feasible. It is just a matter of how much time you are willing to spend on it.

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