Impressive Performance and Reliability
What do you like best about the product?
Stability and Reliability: RHEL is renowned for its stability, making it an excellent choice for mission-critical systems. Its rigorous testing and quality assurance processes ensure a dependable operating environment.
Security: Red Hat prioritizes security, providing regular updates and patches to address vulnerabilities promptly. Features like SELinux enhance access controls and protect against security breaches.
Long-Term Support: RHEL offers long-term support for each major release, providing customers with extended software life cycles and minimizing the need for frequent major upgrades.
Enterprise Features: RHEL offers a comprehensive set of features tailored for enterprise environments, including centralized system management, high availability and clustering capabilities, virtualization support, and containerization technologies.
Red Hat Support: The company's reputation for excellent customer support is highly valued. RHEL users can access knowledge bases, documentation, and receive direct assistance from Red Hat's support team.
Compatibility and Ecosystem: RHEL's broad compatibility with software vendors and extensive ecosystem of certified applications and tools make it suitable for a wide range of enterprise needs.
Open-Source Philosophy: Red Hat's commitment to the open-source community is appreciated by many users, as it fosters collaboration and innovation within the technology landscape.
What do you dislike about the product?
Cost: RHEL is a commercial distribution, and its licensing fees may be considered a drawback for some organizations, especially when compared to free or lower-cost Linux distributions.
Restricted Updates: While RHEL's long-term support is a benefit for stability, some users might find that the release cycle for major updates is more conservative, which may lead to delayed access to the latest features and software versions.
Proprietary Components: RHEL includes some proprietary software components that are not open-source. This might be a concern for users who prefer fully open-source solutions.
Learning Curve: For users accustomed to other Linux distributions or operating systems, RHEL may have a slight learning curve due to its specific tools and configurations.
Software Repositories: RHEL's official software repositories might not have the same extensive collection of packages found in some community-driven distributions, potentially requiring users to rely on third-party repositories or compile software from source.
Resource Consumption: As an enterprise-focused OS with robust features, RHEL might require slightly more system resources compared to lightweight Linux distributions, making it less suitable for very resource-constrained environments.
Community vs. Enterprise Versions: Some users might prefer the community-driven CentOS distribution over RHEL due to CentOS's previous similarities to RHEL, though this dynamic changed with CentOS Stream in late 2020.
What problems is the product solving and how is that benefiting you?
Red Hat Enterprise Linux aims to solve the challenges of stability, security, and scalability in enterprise environments, while also providing a platform for innovation and flexibility.

Has good security, management, stability, and hardening features
What is our primary use case?
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.
What is most valuable?
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.
What needs improvement?
From the administration perspective, I do not have any issues with Red Hat Enterprise Linux. For me, it is more convenient than Microsoft Windows.
For how long have I used the solution?
My organization has been using Red Hat Enterprise Linux for a long time. They have been using it before I joined the organization.
What do I think about the stability of the solution?
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.
What do I think about the scalability of the solution?
Its scalability is good. I would rate it a nine out of ten in terms of scalability.
How are customer service and support?
We never encountered any issues while using OpenShift.
Which solution did I use previously and why did I switch?
I have mostly been working with Red Hat Enterprise Linux.
How was the initial setup?
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.
What about the implementation team?
It was implemented in-house.
Which other solutions did I evaluate?
We did not evaluate other solutions. Red Hat Enterprise Linux is the choice of most of the companies.
What other advice do I have?
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.
