Red Hat Enterprise Linux for SAP with HA and Update Services 9.0

I am currently working with Red Hat Enterprise Linux (RHEL)  as I administer a lot of Kubernetes  clusters installed on Red Hat Enterprise Linux (RHEL) .

For Red Hat Enterprise Linux  (RHEL), I use it as an operating system for our platform which powers all our company's software, mostly for Kubernetes  or for IBM BPM  or IBM PEL.

Red Hat Enterprise Linux  (RHEL) is a robust operating system, and I believe it is much better than Windows. I work with Windows and Ubuntu , but Red Hat Enterprise Linux (RHEL) is the best distribution I have worked with.

The knowledge base offered by Red Hat Enterprise Linux (RHEL) is excellent. Red Hat documentation is the most valuable documentation in the market.

For Red Hat Enterprise Linux (RHEL), I think the most time-saving aspects come from Red Hat Ansible  because we use Ansible  to automate many tasks and repetitive tasks on Red Hat Enterprise Linux (RHEL) and Windows. Ansible automation and the Ansible automation platform are the most valuable products that save us time and money.

Overall, Red Hat Enterprise Linux (RHEL) helps me save time through automation using Ansible. For OpenShift, the core of containers saves time by automating the DevOps processes using the Red Hat pipeline built into OpenShift, Tekton , and source-to-image build. All of this saves us time.

Red Hat Enterprise Linux (RHEL) helps to mitigate downtime and lower risks for me, as most of my work is with OpenShift which enables us to do a zero downtime deployment. The deployment is done without any downtime. Red Hat OpenShift  is a stable system. Red Hat OpenShift  and Linux are very stable and the downtimes are very minimal.

I think Red Hat needs to implement more AI features in the operating system or Red Hat OpenShift.

I have been working with Red Hat Enterprise Linux (RHEL) for about 14 years.

Red Hat Enterprise Linux (RHEL) is very stable. The product is very stable and very mature. All issues are documented in documentation or in the support portal and support knowledge base. When I have an issue, I primarily search the knowledge base and the support portal and find the solution. Red Hat Enterprise Linux (RHEL) is a very secure operating system, and they provide security patching every month.

I find Red Hat Enterprise Linux (RHEL) scalable.

We have many cases where Red Hat helped us with Red Hat Enterprise Linux (RHEL) or OpenShift, and their support is great. On a scale of one to ten, where ten is the best, I would rate the tech support a nine.

Most enterprises work on Linux, and as I am a DevOps and platform engineer, most of our systems run Linux, including Kubernetes, OpenShift, and the DevOps pipeline, all working on Linux. This is why I switched to Linux.

For Red Hat Enterprise Linux (RHEL), the setup is very straightforward. OpenShift is a little complex, but once you do it once, you will master it.

I performed the deployment all by myself.

When it comes to our business value, most of our customers are enterprise-grade customers from banking and government sectors, and they prefer to use an enterprise-grade operating system, not Ubuntu  or CentOS . Additionally, in many cases, we need enterprise support from Red Hat as Ubuntu does not provide this.

I use Red Hat Enterprise Linux (RHEL) , and we have a couple of customers using OpenShift, the Kubernetes  platform based on Red Hat, and also Red Hat Virtualization. My first contact with the Linux platform was with Red Hat.

The best features of Red Hat Enterprise Linux (RHEL)  are its stability and the RPM, Red Hat Package Manager, which is perfect. They also deliver Satellite, a platform for updates. It is a very robust, excellent platform.

For me, and for every Linux distribution, the most important security feature in Red Hat Enterprise Linux  (RHEL) is SELinux. Security is often misunderstood by others. SELinux is very important because it provides security for the kernel. Many people disable SELinux, but it is the most important and most misunderstood feature. People do not understand it. The updates and SELinux are very important to me. SELinux is very good, but it is complex, and I have seen many administrators disable it because instead of helping them, it causes trouble. For example, securing my NGINX  configuration is a pain. It is a very good security option, but I would say it is excellent only if one is an expert.

Red Hat Enterprise Linux  (RHEL) documentation is very good and very complete. Regardless of my opinion about the IBM acquisition, the documentation is excellent.

IBM committed two major mistakes with Red Hat. The first was destroying the CentOS  project, which was a fork of Red Hat. The second was limiting the use of free options and restricting hardware to support Red Hat on just some limited hardware. One can use the system for free, but the statement is not entirely true because it is limited to a couple of virtual processors and I do not remember if it was 24 or 16 GB of RAM. If one goes beyond that configuration, one has to pay, and IBM is IBM. Many companies were in trouble because from one day to the next, IBM said they would no longer support CentOS  and told them to move to another distribution. People had to migrate, and for that reason, there are Rocky Linux , AlmaLinux , and other Linux distributions that are trying to rise and taking advantage of that situation. Red Hat Enterprise Linux (RHEL) is just for corporate companies with money to waste on licensing.

Red Hat Enterprise Linux (RHEL) is very expensive. In the case of our customers, the couple of customers with OpenShift, they have enough money to license Red Hat. They bundle Red Hat with virtualization and OpenShift packages. However, it is not suitable for an SMB company. It is not payable or affordable. For me, it is very expensive.

I use Red Hat Enterprise Linux (RHEL) a lot, though I do not remember the exact frequency.

I have worked with Red Hat support, and it is very good because they have very good engineers. In Latin America, during my time, the support in Spanish was mostly provided by engineers from Argentina. In Colombia, I have worked with a couple of engineers from Colombia, and they were very good. I have not worked with support in English for Red Hat, only in Spanish with those engineers.

My first Red Hat Enterprise Linux (RHEL) certification, Red Hat Certified Engineer, was for version 6, which was approximately 12 to 15 years ago.

I have tried Red Hat Enterprise Linux (RHEL) Image Builder and System Roles, and it is pretty good.

I would rate the support at an eight out of ten. My overall rating for this product is ten out of ten.
