The biggest return on investment when using Red Hat Enterprise Linux (RHEL) for me is just its compatibility. We have one source of truth that's generally accepted in the industry for application software.

I'm using CICD pipelines to manage the OS, just as we do applications.

The feature of Red Hat Enterprise Linux (RHEL) that I prefer most is Insights. I have been using Insights, and it can give me the health of the system, CPU, memory, and everything, allowing me to see everything including security patches, vulnerabilities, and missing patches.

The customer support is excellent. I reached out to them once about a monitoring matter, and the attention was really good. My rating would be nine out of ten.
