How has it helped my organization?
The company that I worked for that employed RHEL was a PACS (Picture Archiving and Communication System - think of an image repository for x-ray, CAT scan, MRI, etc., that allowed radiologists to read the images and report on their findings). Our software was a FDA-certified medical "device," based on an open-source DICOM toolkit. We had a custom repository that served up our packages. We needed a stable, supported version of Linux since we would have to get FDA certification for each major version upgrade.
What is most valuable?
Enterprise support is available for our customers. Pre-RHEL, I used Red Hat desktop for personal PC.
What needs improvement?
What do I think about the stability of the solution?
Rarely were there stability issues. We regularly had servers running for three years without reboot.
What do I think about the scalability of the solution?
Yes, there were scalability issues, but I blame that more on my employer than on Red Hat.
How is customer service and technical support?
Support seemed to be great for day-to-day issues that our customers would experience (the customer would engage Red Hat support and escalate to me if there was no resolution). I only had to engage support once for an escalated issue and their support team tried to pass the blame onto our Hypervisor vendor, when it was indeed an issue with a Red Hat package.
Which solutions did we use previously?
I have used lots of flavors of Linux going back to 1995. Enterprise support was the reason Red Hat was selected.
How was the initial setup?
Easy. Used Kickstart to automate installation and post install config.
What's my experience with pricing, setup cost, and licensing?
I was an engineer, never discussed pricing.
Which other solutions did I evaluate?
CentOS, Slack, Ubuntu, Arch, LFS.
What other advice do I have?
My advice: Kickstart is your friend.
