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.

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.

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.

It is good. I do not have anything to improve for Red Hat Enterprise Linux, but CentOS could be open-source again.

I have been using Red Hat Enterprise Linux since 2014. I have been using Red Hat since 1.2. It was probably 1998.

It is very stable.

We have a cluster with 50,000 cores. It is pretty scalable.

Their customer service is good. We have a TAM. Our TAM is great. Without a TAM, it is hard to get new tickets through.

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.

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.

We deploy it in-house.

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.

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.

We first used it for application installation to run applications on Windows. We had it running on Windows. We then upgraded it. It was still on the IBM platform, but it was still x86. We have now updated it, and it is now running on IBM Linux Z.

We use it for Internet banking, core banking applications, and other peripheral applications.

It has helped with consolidation. When we first started to do clusters, we were using Oracle cluster and Red Hat cluster. The Red Hat cluster was more stable than the Oracle cluster, so we had to uninstall the Oracle cluster and just use the Red Hat feature to have floating IP addresses between two cluster nodes. Having it in a cluster was the single most useful application of Red Hat in the environment.

We use Red Hat Insights, Ansible, and Satellite. Red Hat Insights is helping us big time. A year ago, I was looking at bolstering my team to about five or so administrators. With Red Hat Insights and other tools, I am satisfied with just two administrators. They are there just to manage the system and not necessarily go down into the trenches.

It seems that Red Hat Insights provides vulnerability alerts and targeted guidance, but my team would know that better. I manage a team that does that.

Its stability is most valuable. Its administrative aspect is also good. It is relatively easy to administer. I am familiar with AIX. AIX is super easy. I did not have to struggle much to adapt to Red Hat.

They can make the extended file system dynamic. Currently, we have to bring down the server to add an Hdisk. We cannot extend the database on the fly. We have to have downtime. We want to ensure that we make the blackout periods as minimal as possible. Currently, there is a gap in the file system management. I want to be able to expand the file system in a simpler way and have the application or the database use that expansion without any downtime.

I have been using Red Hat Enterprise Linux since 2004. It has been 20 years.

There is no problem with stability. It is stable. We have a couple of Red Hat Enterprise Linux 4 still running. We also have Red Hat Enterprise Linux 6 systems. The hardware is functional, but the application was retired. We cannot get an update for it. It has been running since 2008.

Its scalability is fine. There is no problem with scalability. We can do it in real-time. Now with containers and other things, we can scale on the fly without much downtime. We can build a small system and scale it. We can start at a much lower level than several others.

It has improved tremendously. I remember when it used to be centralized. I have been to North Carolina to get training, but now they can come to us for the training. The whole support architecture has improved. We can reserve hours for calls when the need arises. If we do not use it, it is reallocated the next month to some other project. They are doing well. I am impressed.

We were using and still are using AIX, but most of the applications have been imported, so we are between AIX and Red Hat. We are also using Windows, but Red Hat has stood out. It is not yet there with AIX, but it is getting there.

We were using Ubuntu and a few other flavors, but they were not organized. They were still too open. The support and the training for Red Hat Enterprise Linux was spot on. It was exemplary. We could find support easily.

We have them in clusters, and we also have standalone ones. We have DR where we synchronize with DR. We synchronize at the file system level with DR, which eliminates some of the application limitations.

We are using it on-prem, but we have applications to be upgraded in another 18 months, which would be a hybrid cloud.

Its installation the first time was overwhelming. Once you get used to it, the team settles down, and you have knowledgeable people, it is a breeze.

We have an integrator, a reseller, and a consultant. Somebody would come in and help us connect the dots. I guess that is their reseller, and then the integrator helps us properly connect the dots.

Pedro is our accounts manager. He probably comes from Puerto Rico, and then there is Lincoln Walters from Jamaica. Together, they help us identify the resources we need for the things that we want to do.

The biggest ROI is in terms of the reduction of human resources required to manage and maintain it. The administrative duties have been vastly reduced. You can even have resources from Red Hat. They have something where you can block certain hours a month and you can just use them as needed. If you do not use them entirely, you can reallocate them. That means you can reallocate unused resources. There are savings on investment.

We are still learning about it, but our TCO has reduced because we do not have to have as much manpower, hardware, and processes to manage and operate.

Licensing is the most attractive part of it. With Red Hat Insights and Ansible, we now know that it was done with the intention of simplifying the licensing so that you get the support for what you have and not necessarily what you want to have.

Red Hat Enterprise Linux has not helped us to centralize development. We have not capitalized on that as yet. I am here at the Red Hat Summit to learn about Kubernetes and containers. It is all new to me, and at this point, I do not know from where to start. I am getting exposed to so many things, but I still need to understand from where to start. I need to know the foundations. In about 18 months, we will be going to containers. We have people developing Dockers, Kubernetes, and other things, but we need to find a way to integrate them. We will have containers running on OpenShift, but we need to know how to secure, store, and manage those containers.

I have participated in a few presentations, and I see that there are prescribed ways to ensure that you maintain compliance by upgrading. In one of the presentations, one of the presenters said to not expand or scale too quickly because some of the applications get left behind. That is something that I am taking away.

The portability of applications and containers built on Red Hat Enterprise Linux will be good for keeping our organization agile. It is flexible. They say, "Build once and run anywhere." That is the buzzword for me.

To a colleague who is looking at open-source, cloud-based operating systems for Linux instead of Red Hat Enterprise Linux, I would say that Linux is for beginners, whereas Red Hat Enterprise Linux comes with the bells and whistles and the stability for business. It is an enterprise-grade software.

Overall, I would rate Red Hat Enterprise Linux a nine out of ten. There is innovation and adaptability. Ten years ago, it was unheard of. It has grown, and it has been growing tremendously.
