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 most valuable feature of Red Hat Enterprise Linux is its command-line capabilities, which allow you to execute large operations quickly. For example, let's say you want to create a hundred files or directories. In Windows, you need to create each one by hand, which is difficult and time-consuming. Linux has multiple commands to create files in a few seconds. It also has the "top" command that gives you all the processes running and their utilization of resources like CPU, RAM, etc. That isn't possible with a management console or GUI."
"When it comes to security, scalability, and robustness, Red Hat Enterprise Linux (RHEL) excels in all aspects. That's why we rely on this operating system."
"Red Hat is a good partner for us, and the service and support guides are really valuable for understanding and improving our knowledge in this area."
"The stability is awesome because we have had only a few issues in operations."
"The stability and reliability of the RHEL platform are good."
"Red Hat Enterprise Linux (RHEL) scales with the growing needs of our company quite effectively, as we're still on-prem and a VMware shop, so it functions seamlessly."
"The customer service and technical support for Red Hat Enterprise Linux (RHEL) is pretty good."
"OpenShift is the most valuable feature because it can be used to create applications on the fly."
 

Cons

"The development teams could sharpen their skills. They should offer applications on the net."
"The customer service and technical support for Red Hat Enterprise Linux (RHEL) are okay; I would rate it a five out of ten."
"I would say Red Hat Enterprise Linux (RHEL) is definitely expensive. Compared to open-source Enterprise Linux like Rocky Linux or Alma, it's definitely very expensive."
"I would like to see the GNOME system monitor feature, which shows CPU usage and other aspects. It will help to save time."
"I believe they need to improve in terms of compatibility between services. I know that it's difficult to follow the different versions and maintain compatibility."
"Regarding improvements, I think RHEL could benefit from better user interface enhancements for future releases."
"The price is something that can be improved, as they are still being undercut."
"My number one request for improvement would be better Kickstart functionality, as I feel the Kickstart notation is outdated and it's not programmatic, so that would be my focus point, based on what I do."
"Deploying clusters on Red Hat, as well as on Oracle Linux, is a bit involving. I'd like them to simplify the setup or at least give meaningful log files to be able to see what's happening at the cluster level."
 

Pricing and Cost Advice

Information not available
"In terms of the solution’s single subscription and install repository for all types of systems, we can have as many RHEL installations as we want because we have a specific subscription that entitles us to have as many RHEL services as we want. We pay for a subscription and with that we get RHEL and Satellite as well."
"We use open source. We only have a subscription for support."
"My company has acquired five to ten licenses from Red Hat Enterprise Linux (RHEL)."
"Its licensing is pretty confusing. There are a lot of subscriptions, and it isn't always clear which subscription is the best, but with their support, it's easy to find the right one."
"The licensing with Red Hat is on par with other organizations like Microsoft. We have a site license, which gives us a certain number of servers, perhaps 25,000, for the type of license that we have. That works really well for us."
"I'm unsure what the standard RHEL license costs for one machine. We pay for premium support that guarantees a response in two hours."
"Red Hat is stable, and we always opt for the lower-tier subscription, which is affordable."
"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."
