We are a fintech company that uses Red Hat Enterprise Linux for enterprise and financial applications. Red Hat Enterprise Linux is deployed on servers at two sites. Access is mostly limited to IT staff because it is only used on our servers, not employee workstations.

Red Hat Enterprise Linux
Rock solid Linux
Best Enterprise-level OS out there
Solid, Stable, Secure Server OS
The Linux operating system makes better use of system resources than Windows-based servers. For this reason, any Linux makes better use of things like memory and CPU. RHEL generally sets up a small subset of required processes (that you can also easily tailor to your needs) on install. Things are a little more "additive", meaning it will start with more bare minimum services, and you add what is needed for your particular case. They try to strike a balance between most commonly-needed things, and security.
Having software installed via RPM and centralized in repositories (which you can self-host by purchasing Satellite) makes it incredibly easy to keep your environment updated and scriptable.
Offers performance stability, and it's easy to scale up or down by adding servers
What is our primary use case?
How has it helped my organization?
Red Hat Enterprise Linux offers performance stability, and it's easy to scale up or down by adding servers. The OS is easy to monitor and integrate with other systems. We use all these applications as containers. Red Hat has a container platform called OpenShift that we use to deploy containers. It's effortless to deploy and redeploy Red Hat Enterprise Linux. You can easily deploy it across multiple platforms and move it from one provider to another.
The operating system helps us meet security standards for the financial industry. You need high levels of security in this business to protect your financial data. Red Hat Enterprise Linux has various security features.
We use the System Roles feature primarily with Ansible. It's powerful. You can use it to perform complex tasks, and it simplifies processes. For example, it helps you change network settings for storage, security, monitoring, etc. System roles help us automate security configurations and maintain consistency across systems. They have playbooks we can get from their website, and it's all based on system roles.
My company uses Red Hat Insights only for systems with internet access, but most of our environment is offline.
What is most valuable?
Red Hat Enterprise Linux is easy to manage, update, and integrate. I also like Red Hat Enterprise Linux's built-in security features. You need to enable them by default or keep them enabled if you want your system to be secured. It protects most of the system components.
What needs improvement?
Red Hat Enterprise Linux's monitoring could be improved. I would like additional monitoring features, like a greater ability to monitor services and workloads running. Satellite can provide centralized monitoring of subscriptions and deployments. You can build a monitoring console, but there is no native monitoring.
For how long have I used the solution?
I have been using Red Hat Enterprise Linux for four or five years.
What do I think about the stability of the solution?
Red Hat Enterprise Linux is stable like every other Linux distro. It works fine. We have had no issues.
What do I think about the scalability of the solution?
Red Hat Enterprise Linux is easy to scale. You can clone it, deploy another instance, and scale it up with a few changes.
How are customer service and support?
I rate Red Hat's support an eight out of ten. I contact them often. Red Hat's support is helpful. They can solve your issue most of the time or point you in the right direction.
How would you rate customer service and support?
Positive
How was the initial setup?
Deploying Red Hat Enterprise Linux is mostly straightforward, but it depends on your requirements and the settings you need to apply. We typically do everything in-house. Red Hat Enterprise Linux requires a little maintenance. We need to do patching, clean up the file system, rotate logs, etc.
What other advice do I have?
I rate Red Hat Enterprise Linux a nine out of ten. If you don't know anything about Red Hat Enterprise Linux, you should read up on it. It will do everything you want. Red Hat Enterprise Linux is excellent.
