RHEL 9.6 with support by ProComputers

I am working on a Cloud Infra project in which many analytics applications are hosted on Cloud Infra, and their applications are hosted on Red Hat Enterprise Linux (RHEL) .

The applications are customer-facing and mainly focus on analytics regarding an automotive company.

The experience with pricing, setup cost, and licensing for Red Hat Enterprise Linux (RHEL)  was pretty smooth, as we can subscribe the servers from the RHEL portal.

We use Red Hat Enterprise Linux  (RHEL) on both on-premises and public cloud.

One of the best features of Red Hat Enterprise Linux  (RHEL) is that it is lightweight and it is the industry standard.

Whenever I start the servers, they switch on very fast compared to other Linux servers.

We can deploy clusters in Red Hat Enterprise Linux (RHEL), and we can scale up and scale down our infrastructure with the help of the RHEL server.

The subscription model and vendor support are also good. We can subscribe our servers to RHEL so that we can get the packages installed for our project-related dependencies.

Red Hat Enterprise Linux (RHEL) has positively impacted my organization. The speed of the applications has improved after deploying them on RHEL.

Whenever we face an issue and need to reboot the server, it comes up very fast compared to other servers, and it has improved the latency of our applications.

Time has been saved since using Red Hat Enterprise Linux (RHEL), and the application performance has improved after using it.

There should be some automation for patching the servers in Red Hat Enterprise Linux (RHEL). Patching in the sense that automatically, whatever servers we need, we can patch them using a utility present inside RHEL.

It is stable, but compared to Red Hat Enterprise Linux (RHEL), Ubuntu  is more stable for Kubernetes  and Docker-related applications. If improvements can be made in RHEL so Docker  and Kubernetes-based applications can be deployed more easily, that would be great.

I have been using Red Hat Enterprise Linux (RHEL)  regularly in my current role since 2021, and I leverage RHEL  for our daily Linux administrator administration tasks, orchestration tasks, patching, monitoring, and self-healing, while ensuring compliance with all security standards. From a product perspective, RHEL's robustness allows us to use Ansible , Jenkins , and ArgoCD to optimize our CI/CD processes, and we manage more than 50 clusters across five regions: Amer, Paris, Hong Kong, North Singapore, ensuring all deployments are secure. It is reliable and offers enterprise support, making it suitable for scaling workloads in both on-prem and cloud environments.

I have been using Red Hat Enterprise Linux  (RHEL) on a daily basis as a foundation for my DevOps and Kubernetes  infrastructure tasks, where it stands out as a primary tool for managing clusters. I regularly monitor system administration tasks such as patching, performing OS level troubleshooting on RHEL servers, and executing kernel updates on a monthly cycle, all while leveraging automation using Ansible . For monitoring, we utilize Prometheus, Grafana , and Kibana to visualize performance metrics, health checks, and set up alerts for CPU, memory, and disk usage on RHEL nodes. Regarding container orchestration on Kubernetes , we are responsible for deploying and maintaining workload shifts on OpenShift and Kubernetes clusters, which are built on RHEL nodes to ensure stability and scalability. Thus, RHEL is a core VM for both Kubernetes and OpenShift, with OpenShift being the main focus to ensure our infrastructure is stable and ready for daily use.

The best features I have seen in Red Hat Enterprise Linux  (RHEL) include its scalability, enterprise-grade security, and stability. It incorporates features such as SELinux, kernel live patching, and RBAC systems, making it very reliable for production environment workloads, allowing for automated cycle processes akin to Kubernetes, which can manage itself over long-term stability, demonstrating good, consistent performance along with integrated Linux support via Ansible and OpenShift. Thus, RHEL is a trustworthy platform.

Compared to other operating systems, Red Hat Enterprise Linux (RHEL) is specifically designed for production environments. It integrates tightly with OpenShift, Ansible, and other tools that others cannot deeply support. RHEL seamlessly works in hybrid cloud and container platforms, and in comparison to Windows, RHEL provides greater flexibility for containerization and DevOps-related tools, making it a more reliable option.

In Societe Generale, Red Hat Enterprise Linux (RHEL) has helped us maintain a secure environment across our container platforms through SELinux and kernel patching, which has directly lowered the risk of downtime and improved trust in the system. Notably, the ability to automate server patching and manage cluster upgrades has eliminated the need for manual intervention, significantly reducing errors and saving several hours of work. As a result, our team can focus on more innovative topics rather than repetitive tasks, leading to improved deployment times and increased reliability by around 20 to 25%. Overall, RHEL has made scaling applications in hybrid cloud environments much smoother, positively impacting my organization by providing a stable and secure platform.

By using Red Hat Enterprise Linux (RHEL), our team saves approximately 10 hours per week on routine patching and monitoring housekeeping tasks, which allows us to focus more on innovation topics. The time saved has led to improved knowledge among the team on how to create pipelines and better support application teams, thereby positively influencing delivery timelines and productivity.

Red Hat Enterprise Linux (RHEL) is stable and secure, but I think one area for improvement is that licensing should be automatically updated, particularly in multiple environments. Additionally, a faster GUI experience would save time, which would enhance usability.

From the suggestions for improvements, I would advocate for simplifying license management and providing a more efficient web console that can run RHEL faster. Furthermore, built-in tools for monitoring and automation should be made easier to grasp, as we create many dashboards using Grafana , which are much needed.

I have been working in my current field for more than four years.

I have only used Red Hat Enterprise Linux (RHEL) and did not evaluate other options, as RHEL is very stable and designed according to its lifecycle. My consistent experience with RHEL underpins its foundation for OpenShift and Kubernetes clusters, supporting critical applications without unexpected failures, especially with Ansible handling our patching, which contributes to better stability.
