We have extensive contracts with Red Hat. We have it for the operating system. I manage the cloud deployment for GCP, and we have got Red Hat Satellite running in GCP. All of our VMs run on Red Hat Enterprise Linux in the cloud. On-prem, we are running Red Hat Enterprise Linux on our OpenShift cluster, and we have a supercomputer that has got 753 nodes with 50,000 cores running on Red Hat Enterprise Linux. We use a lot of the other products too.

Linux in a high demanding environment
Have been a RedHat SA for 12 years and a lifetime working with computers
Consistent, scalable, and geared toward security
What is our primary use case?
How has it helped my organization?
There is consistency across the deployment. Generally, when you are looking to hire people, if you hire people who know Red Hat Enterprise Linux, they have a certain level of understanding that goes along with using the operating system.
It is easy to secure. It has a lot of built-in security features, and it is very stable, which is a big deal.
It makes it easier to have one team that deals with both on-prem and cloud because there is a uniform operating system and tooling. You do not have to have a set of admins where one knows one thing and the other one knows another.
Red Hat Enterprise Linux has enabled us to centralize development. We are using the same platform everywhere. It is the same tooling, and everyone is working in the same system.
We are using Red Hat Enterprise Linux for containerization projects. We are building out OpenShift on-prem right now on bare metal. We are running the hub cluster from GCP to spin up the bare metal cluster on-prem. We will hopefully be moving more and more things towards containerized workflows. We are running OpenShift, so it all runs on top of Red Hat Enterprise Linux.
For security, SELinux is built in. It is out of the box. It is built towards building a secure system. We are in the process of working on compliance and getting this 800-171 certified. That is in process. They have regular security updates and lots of tools for rolling out updates. In that sense, there is a continuous upgrade path that is well-worn and fairly easy to maintain.
In terms of portability of applications and containers built on Red Hat Enterprise Linux for keeping our organization agile, when it is in a container, it does not matter if you are running a UBI container or some other sort of container. If you have an environment that will run a container, you can throw a container in it, and it will run, so the portability does not belong to the OS at that point. It belongs to the containerization system.
What is most valuable?
It is consistent. It is geared toward security. I am used to it. I know only Red Hat Enterprise Linux. I do not know Ubuntu or any of the other flavors of Linux.
What needs improvement?
It is good. I do not have anything to improve for Red Hat Enterprise Linux, but CentOS could be open-source again.
For how long have I used the solution?
I have been using Red Hat Enterprise Linux since 2014. I have been using Red Hat since 1.2. It was probably 1998.
What do I think about the stability of the solution?
It is very stable.
What do I think about the scalability of the solution?
We have a cluster with 50,000 cores. It is pretty scalable.
How are customer service and support?
Their customer service is good. We have a TAM. Our TAM is great. Without a TAM, it is hard to get new tickets through.
Which solution did I use previously and why did I switch?
I have used many solutions. I have used many that predate Linux. For Linux, I have run Slackware, but that is just for fun. Professionally, it has all been Red Hat Enterprise Linux.
How was the initial setup?
Our deployment experience is good. For the things in the cloud, I use Satellite. I build images and deploy from images to the cloud. It is a mutable deployment chain rather than a standard upgrade path.
What about the implementation team?
We deploy it in-house.
What's my experience with pricing, setup cost, and licensing?
The vendor management takes care of that.
We have an enterprise agreement. From our department's standpoint, everything gets rolled into the enterprise agreement, which is great because we never see it.
What other advice do I have?
To a colleague who is looking at open-source, cloud-based operating systems for Linux instead of Red Hat Enterprise Linux, I would say, "Why would you look at something other than that?" I have built things on Fedora and Red Hat Enterprise Linux. I was out of the industry for a while, and I came back, and I focused on Red Hat Enterprise Linux because it pays better. There are more standardized jobs in the area if you know Red Hat Enterprise Linux. The certification that you get from Red Hat means something quite specific.
I would rate Red Hat Enterprise Linux a nine out of ten.
