We use Red Hat for everything or we have a Red Hat derivative.

We use it on-prem and on the cloud. We use it in a hybrid cloud environment. We see it everywhere. We have a more consistent view. We do not have the same churn that we have with other operating systems. The longevity of Red Hat Enterprise Linux is pretty cool.

We see it being used a lot for containerization projects. A lot of the things that I am involved in involve Red Hat Enterprise Linux. It is a great experience. It is something that we know we can come into and have a good outcome. It is very reliable.

They are at the forefront in terms of built-in security features. I have seen a lot of things that they are doing. We would like to see more of that because security is something that is impacting everyone. 

The portability of applications and containers built on Red Hat Enterprise Linux is great for keeping our organization agile. It is consistent. When I build an image with Red Hat Enterprise Linux, I know what is in it. I know it is trusted. I do not have the same churn that I would have with others. The way they support it and the way they communicate are well-known.

It is the number one Linux operating system that we've run in to, and the way it does things is the way I prefer. I do not know if it is because they did it first, or they just read my mind.

The number one feature we like is that it is a very reliable platform. It is a very consistent platform. There is very little that we cannot do with Red Hat Enterprise Linux, and there is very little that we worry about when we are running a Red Hat distribution.

Red Hat started as a very open and outwardly focused release, but recently, some of the changes that were made have affected that reputation. From the standpoint of what they can add to the product, the product is pretty stable. 

They continue to push the ecosystem forward, but as a consumer, what was most important for me was the reputation of openness that Red Hat has fostered. I would like that back. I wish they did not care about CentOS and things like that. I have seen my customers push away from Red Hat as a result of that perception, which is weird because it does not change anything. I wish they would value that. Because of new owners too, the perception has changed suddenly.

I started with Red Hat before Enterprise Linux. I started in the nineties when Red Hat first went on floppy disks. They had a bunch of floppy disks. That was my first release, and then they started doing it via CD-ROMs. The first Red Hat Enterprise Linux release that I used was 2 or 2.1 in early 2000. I remember the Red Hat person coming to where I was working at the time and saying that they are going to start this enterprise distribution. We were really skeptical. We were like, "We have Red Hat. We love Red Hat. Why are you messing with a good thing?" It is kind of funny.

It is stable.

It is scalable.

It has always been solid. It is getting a little worse than it was before. When you get to the right people, you always get amazing support. It is just a bit harder to get to the right people. I would rate their support a ten out of ten. I love it when we get there.

Positive

It has been very long since I started working with these types of solutions. I have used them all.

We use it in the cloud. We use it on-prem. We use it in a hybrid situation. We use all cloud providers.

Its deployment has always been simple.

I am a consultant and integrator.

For us, our ROI is the predictability of Red Hat. We know what is coming. It is well-communicated. We could see the upstreams. We know how it is supported. We know how they communicate about CVEs and things like that. We know how to iterate the ecosystems. We know how to deal with RPMs. Very rarely, you are like, "This is brand new." It always usually works into a construct. There is always a utility that you can use to wrap complex things, such as SELinux or containers. There is always something.

We have done bake-offs before with the big three that everybody talks about. There is Red Hat. There is SUSE, and there is Ubuntu. Personally, I am not a fan of Ubuntu. I do not run a desktop, which is probably why. The ones that I run into all the time are SUSE or Red Hat Enterprise Linux.

If I were not going with Red Hat Enterprise Linux, I would go with a Red Hat Enterprise Linux clone. In business, I would always use Red Hat. Personally, I would use CentOS just because I prefer the way Red Hat organizes everything, so it has always been Red Hat or a Red Hat clone.

I would rate Red Hat Enterprise Linux a ten out of ten. I love it.

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.

Positive

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.
