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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Red Hat Enterprise Linux is stable.

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

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

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

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

We have Red Hat Enterprise Linux deployed in one location.

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

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

We use Red Hat Enterprise Linux for servers. We have deployed application servers and database servers on it. We run Oracle Database, WebLogic, Apache, and JBoss on it.

Red Hat Enterprise Linux is very important for our organization. We are very sensitive to security.

It is not difficult to move workloads between the cloud and the data center using Red Hat Enterprise Linux. Mostly, our teams use file servers centrally, and then they use scripts so that it is done automatically in the background. Initially, they may get problems while connecting due to the security or firewall, but once the connection is established, we do not see any problem with that.

Red Hat Enterprise Linux has helped to avoid cloud vendor lock-in. I am not sure how much our organization has saved in costs by avoiding cloud vendor lock-in, but we would have saved a good amount.

It is very stable and robust. My team is very comfortable working with it for all end-to-end activities. They can work with it very easily. They prefer working through the console rather than the GUI.

Its resiliency is good. There is no doubt about that.

I don't prefer Red Hat Enterprise Linux for desktop over other options.

I have been using Red Hat Enterprise Linux for a good amount of time. It has been eight to ten years.

It is very stable. I would rate it a ten out of ten in terms of stability.

It is very scalable. I would rate it a ten out of ten in terms of scalability. It is highly available and scalable for servers.

It is good. I do not see any challenges. I would rate their support a nine out of ten.

We choose an operating system based on the needs and the use case. We use different operating systems for different purposes, so they are not comparable. For example, for desktops, Linux is not the best. For desktops, Microsoft Windows is the best. Similarly, if you are using any Microsoft products, such as SQL Server, Microsoft Windows is the best option. However, nowadays, we also have Microsoft products installed on Linux.

I am not involved in its deployment and maintenance. We have a separate team with 40 to 50 people around the globe for that.

We most probably have both on-premises and cloud deployments on a private cloud, but I am not sure. Our infrastructure services team takes care of that.

We have got a good ROI, but I do not have the metrics. I would rate it an eight out of ten in terms of ROI.

Its pricing is good and competitive.

I would recommend it based on the use case and the budget. If it meets your needs and budget, Red Hat Enterprise Linux is the best option.

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

I provide consultation to clients for their mission-critical applications. Its primary use case is running containers and microservices on Springboard.

My customers use versions 7.2 or 7.3. I have used versions 8.2 and 8.4. I have tried version 9, but I use version 8.4 specifically because it supports HighPoint RAID for storing the data, whereas the client applications run on the much lower version.

There are benefits in terms of price, security, and stability to reduce the risk of applications going down or something like that. A vast majority of systems are on Red Hat Enterprise Linux than on other distributions, which is another benefit.

Red Hat Enterprise Linux helps to achieve security standards certification. They use it in the PCI DSS segment, so it enables the applications to be compliant with all these security aspects.

Red Hat Enterprise Linux is very stable. It has been in the market for many years, and it is used by large organizations.

Their documentation and knowledge base are valuable. As an individual developer, whenever I have problems, it is easy to find the information. Their knowledge base is seamlessly integrated with the software. Whenever I have a question, it directly takes me to the knowledge base. It is well documented.

It supports scripting very well. Everything is scripted. A snapshot is taken in the VM, and the script is applied. It lends itself to better security and governance processes.

Its installation on a RAID or cluster system is something difficult. There are specific teams working on that. The GRUB configuration is also a little different from the other Linux distributions.

In terms of additional features, as technology keeps evolving, the product will also have to evolve. For example, Microsoft Windows has come a long way. In Windows 11, there are so many features that are fundamentally the same as the oldest version, but there are other aspects or processes that have improved. macOS has also evolved over time. Similarly, in the Red Hat Enterprise Linux that I used in 2003 and the one that I am using now, some things are the same and some things have changed. Red Hat can continue to engage clients, understand the use cases, and update them.

I have been using Red Hat Enterprise Linux since 2002 or 2003. Red Hat has a vast variety of products. I have only been using Red Hat's operating system. I have not used Red Hat's other products.

It is very stable.

It is scalable, but I do not have experience in building hundreds of systems on a VM.

I have not used their technical support at all. I only use their documentation portal for self-support. Our production support team interacts with Red Hat's support team.

As a developer, I use both SUSE as well as Red Hat Enterprise Linux. My personal preference is Gentoo, but no one runs Gentoo on a production system. Gentoo is better in terms of customization. You can choose what you want.

I am not directly involved in its deployment, but I am planning to build an application. At that time, I will be deploying it myself. In the organization where I work as a consultant, there is a segregation of roles. There is a production support team, there is a development team, and there is a DevOps team. I am a part of the development team.

Its initial setup is straightforward. It is not complex. It also depends on the architecture, high availability, etc.

In terms of deployment, earlier, it was on-prem, but now, it is on the cloud. My client runs about 150 VMs on the cloud in the production, staging, and QA environments. Most of the things have been consolidated into VMs. The migration is complete. It was not that complex.

I have not measured that, but it should pay back for itself easily. The ROI should be reasonable. The cost over a period of time should be minuscule. As compared to other OSs, it is better to go with a big, known, and trusted vendor.

As a developer, I pay around 10,000 Yen, which is around $100 per annum for support. SUSE and Red Hat are typically the same without standard support. The pricing is not a big deal. Enterprise customers will pay for the support. Enterprises have the money for one or two products like this that are reliable and supported.

As a consultant, I advise customers to go for support. You mitigate risks by having support. For your personal usage, you can manage without support, but when it comes to the enterprise level, you need to delegate things to people, and it should be through the proper channel. You need a proper point of contact.

I would advise following the best practices recommended by Red Hat. It will minimize the downtime of the application or system. Partner with the vendor and get that support. Know the business case and build a strong relationship with the vendor. Trust them and tell them your use case, and they will come up with the best solution possible.

I am not a big authority on Red Hat or other Linux or Unix products. Only recently, I have been exposed to the concept called hardening and penetration testing. I do not know whether Red Hat provides a hardened version of the OS. My basic distribution is Gentoo which provides a hardened version of Linux. On the client side, the organizations we work with have different departments, such as the security department and the compliance department. For security, they work with various options that are available. For penetration testing, we engage a penetration testing consultancy company once a year.

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

My organization has different departments. In my department, we mostly work with containerization. I am using Red Hat Enterprise Linux as a part of OpenShift. I use the basic package and base image of Red Hat Enterprise Linux.

For scale-up in our platform, we use CoreOS as the master, and for the workers, we use the Red Hat Enterprise Linux service. From OpenShift version 4.10 onwards, we cannot use Red Hat Enterprise Linux 7 worker nodes. We were using Red Hat Enterprise Linux 7 worker nodes, so we upgraded to Red Hat Enterprise Linux 8.

For OpenShift, there are some recommendations from Red Hat in terms of what needs to be used for the control plane and what needs to be used for the worker nodes. When you are using CoreOS and Red Hat Enterprise Linux worker nodes, there are some difficulties in managing them. For example, when you upgrade OpenShift, you need to upgrade two times. The control plane is upgraded separately because it uses CoreOS. The control plane has a lot of certificate updates that will in turn be updated on the worker nodes, so you have one restart of all worker nodes, and then when you need to upgrade your worker nodes, there will be one more restart.

Overall, you have two reboots in your production environment, which is an issue, but it is related to your choice of product in your environment. We have this issue because we opted to use Red Hat Enterprise Linux 7 or Red Hat Enterprise Linux 8 worker machines, whereas Red Hat recommends using CoreOS because it is pretty fast in terms of rebooting and functionality. When you upgrade the control plane, that itself will update the worker nodes, so you are done in one shot. When you need to upgrade your Red Hat Enterprise Linux machines, you need to use the Ansible Playbook. You can then upgrade to Red Hat Enterprise Linux 7, 8, or any other version. Regardless of the versions, you can upgrade the operating system and the OpenShift version. For this purpose and for some ad-hoc activities, we are using Ansible Playbooks.

For us, its security, management, stability, and hardening are most valuable. All of these features are better in Red Hat Enterprise Linux as compared to Microsoft Windows.

Red Hat Enterprise Linux is very good in terms of risk assessment. It is also good for maintaining compliance. It is better than Microsoft Windows.

From the administration perspective, I do not have any issues with Red Hat Enterprise Linux. For me, it is more convenient than Microsoft Windows.

My organization has been using Red Hat Enterprise Linux for a long time. They have been using it before I joined the organization.

It is pretty good in terms of stability. It is a stable product. I would rate it a nine out of ten in terms of stability because sometimes the packages can have bugs.

Its scalability is good. I would rate it a nine out of ten in terms of scalability.

We never encountered any issues while using OpenShift.

I have mostly been working with Red Hat Enterprise Linux.

I have been involved in the deployment of OpenShift. It is pretty straightforward. We just need to get the licensing, and we just need to create a pool for our containers session in Red Hat Satellite. We can do the configuration from there. It does not take long because we are adding the nodes to OpenShift. During the scale-up process, we only need to subscribe to the nodes with the Red Hat subscription. It does not take much time. If we have a good spec, the scale-up would not take much time. It would take less than twenty minutes. It is pretty fast.

In terms of maintenance, when we have the bug report, we need to do the security assessments. Over time, there might be some bugs related to some packages. At that time, if it is critical, we will be scheduling a maintenance activity on our platform.

Red Hat provides high availability from the application perspective. You get high availability when you are using OpenShift, so when you are doing a maintenance activity on the OpenShift side, there would not be any downtime. The high availability is very good. For the end-users, there would not be any application outages if you configure your application with proper replicas. They would not even realize that there is a maintenance activity happening to the underlying workers.

It was implemented in-house.

We did not evaluate other solutions. Red Hat Enterprise Linux is the choice of most of the companies.

If you want to integrate with OpenShift or build an OpenShift cluster with the master Red Hat Enterprise Linux and worker Red Hat Enterprise Linux, you can do that, but you need to plan your upgrade or maintenance activities. It would be better if you choose CoreOS for both. CoreOS would be a better choice in terms of maintenance activities or upgrade activities in the future. If you cannot afford that, you can go with the Red Hat Enterprise Linux operating system, but you need to do two upgrades. You first need to upgrade the control plane and then you need to separately update your worker nodes. That is the only thing you need to keep in mind.

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