We use Red Hat Enterprise Linux for our applications. I use it for many applications, especially SAP.

We install it on the server so that we can install our applications running on that server.

The benefits I get from this operating system are that it's secure, easy to use, and stable.

I find the clustering feature of Red Hat Enterprise Linux the most useful. It helps us to cluster our application service to maintain high availability.

I access the knowledge base offered by Red Hat Enterprise Linux through their websites. The knowledge base is helpful to me.

The Image Builder is easy to set up, and overall, it is helpful to me.

I recommend that they improve their virtualization product, specifically the management console.

Support should definitely be improved.

I do not have any complaints with the stability of Red Hat Enterprise Linux.

We use Red Hat Enterprise Linux in multiple locations. We are using it in the IT industry.

I would rate their support a three out of ten. I find them slow to respond. The quality of support is not acceptable in the way they provide solutions.

Negative

I manage Red Hat Enterprise Linux (RHEL) systems by installing it from the disk, specifically from a CD-ROM. It requires maintenance from our side. We have 11 people for maintenance in the team.

I have not seen a return on investment since I started using it. The cost is a reason for that.

I find the cost of this solution expensive.

I would recommend not using Red Hat Enterprise Linux because there are better products out there. I prefer SUSE because of the cost and other features.

I would rate Red Hat Enterprise Linux as four out of ten.

We use Red Hat Enterprise Linux across different versions, from six to nine, to run various applications. Our main area of focus involves using Satellite support to manage and patch both the Red Hat Enterprise Linux OS and specific applications like OpenShift and other products supported by Red Hat. We have multiple environments, including Azure, AWS, and a standalone eXs host. 

Red Hat Enterprise Linux's patching process needs improvement, particularly in achieving consistency. Currently, when you patch, you might not have control over the timing, leading to different software packages ending up at different patch levels. This lack of consistency can make it challenging to manage and control the various components effectively. My background is in IBM AIX, so the patching is based on the technology level and the service pack level, so all the related patches stay at the same level.  

I have been using Red Hat Enterprise Linux for ten years.

I would rate the knowledge base offered by Red Hat as average. I would rate their support as a three out of ten.

Negative

We also use IBM AIX. I prefer AIX, but Red Hat Enterprise Linux is cheaper. However, IBM has real technical support. You can call a 1-800 number and get a technician on the line. That's real technical support. Red Hat requires you to email them and schedule a call. 

Overall, I rate Red Hat Enterprise Linux as a five out of 10. 

I don't see Red Hat Enterprise Linux's built-in security features as effectively simplifying risk reduction and compliance. We use AIX, but still, we face a lot of vulnerabilities from Red Hat that need frequent patching, often monthly. This frequent need for updates, along with the rapid changes in Red Hat Enterprise Linux releases, can be frustrating and lead to instability. In the banking industry, where we take vulnerabilities seriously, these frequent releases and lack of stability can be problematic.
