Automation has transformed daily operations and supports secure, continuous infrastructure
When considering improvements to Red Hat Enterprise Linux (RHEL), I see one primary area. Within your portal, if you provided more study material along with demonstrations similar to the sessions we are attending, which feature a user-friendly guide, you could incorporate this into your Red Hat console. When I want to install an agent or something else, typing in the console should provide me with clear step-by-step instructions. Throughout the years, installation steps have been available, but regarding AI agents or Ansible automation, I need to verify whether clear information exists. Including this information would be beneficial. Additionally, if you add the sessions that have occurred to your portal or another location, this would help us review them multiple times to gain better understanding. Time is limited, and many sessions occur simultaneously, making it impossible to attend everything. Making these sessions available on your website would be very helpful.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Flatcar's support is good, and the version I am using is stable and allows us to make needed changes."
"The feature of having a single pane of glass administration point for all systems improves my company's efficiency significantly as my scope of responsibility includes maintaining systems at about 40 data centers across the United States plus internationally."
"Red Hat Enterprise Linux's built-in security features are very good."
"Satellite 6.10 and RHEL integrate with each other perfectly, enabling me to be a single person managing my images since it does a lot of the manual labor that I used to do, such as building patches, doing system maintenance, and keeping systems consistent, which has offloaded those responsibilities and given me more work-life balance."
"I chose Red Hat Enterprise Linux (RHEL) because it is so user-friendly, in every server I need to use it for security reasons, and it is user-friendly for everyone."
"Red Hat Enterprise Linux (RHEL) provides us with a standardized Linux that has controlled package versioning so that there's no scope for issues when we're applying patches."
"For things that just have to be up and running, Red Hat is the product that you want to use."
"Overall, I would rate Red Hat Enterprise Linux (RHEL) nine out of ten."
"It helps our customers save money and do things quickly."
 

Cons

"The development teams could sharpen their skills. They should offer applications on the net."
"This solution could be improved if it was easier to set up and run in cloud environments. It can also be costly to manage a large OpenShift environment."
"Right now, since my company is in an air-gapped on-prem network, it is really tough to go through all the RPMs that we have to have based on different STIGs."
"Red Hat Enterprise Linux (RHEL) is very expensive. It is not suitable for an SMB company; it is not payable or affordable."
"Customer service and technical support needs work. We submit an issue to them and go back and forth for three or four days just defining the issue so they understand the problem."
"Linux overall needs improvement. They cannot go much beyond what Linus Torvalds's kernel implementation can do."
"One challenge we've faced is with databases. Configuring and implementing DBs is much easier in non-Red Hat Enterprise Linux systems, especially in Microsoft."
"Considering an area where the solution lacks, I think we can look into a lot more automation and integrations with Red Hat Enterprise Linux and other products."
"The performance of Red Hat Enterprise Linux (RHEL) could be improved, especially under high load scenarios or when running applications involving AI."
 

Pricing and Cost Advice

Information not available
"We are a huge VMware shop. Our licensing cost works well with Red Hat. We license based on the data center. The way our license works is that we can run as many Red Hat VMs as we want and pay for a single license. On the VMware side, we gain a lot, and it makes much more sense."
"The licensing for Red Hat Enterprise Linux in Peru is very expensive."
"I do not know enough to give a comprehensive answer, but other operating systems are in use at my company because they have more favorable licensing terms."
"The tool is getting expensive."
"RHEL has a decent pricing model. It's a subscription, which makes sense. The OS itself is free, but you pay for the support. I have never heard any complaints about the pricing."
"The setup cost is non-existent. With licensing, there was a little snafu because I misread something. There was a slight learning curve because we use virtual data center licensing. We had to understand how it all maps. We had to understand how that mapping works when the hypervisors are Red Hat or VMware. There is a slight learning curve, but it worked out. It ends up being easy."
"Pricing depends on the model used, costing about $3,000 per virtual host in the virtual environment. It varies depending on whether you get high availability. There are modules that are upsold such as kernel patching, which we do not use due to cost considerations."
"It is very straightforward. We do not have to think much about having to get all the subscriptions related to the Red Hat Enterprise Linux fleet that we have because all the subscriptions came in pairs of CPUs or even for an entire bare-metal server."
