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."
"I find the satellite feature the most valuable. It allows us to manage disconnected workstations, keeping their patching, software updates, and bug fixes up to date."
"The high availability capability and the support functions we get from Red Hat Enterprise Linux are among the most valuable features."
"The console is user-friendly. The web console provides an interface to manage all your resources."
"Satellite has no parallel in the Linux distro world, especially for an enterprise, enabling me to manage my servers, patch them, create content, get them binaries, updated security updates, and all that."
"Red Hat Enterprise Linux provides a strong foundation for compliance and offers extended support, which is particularly valuable for critical upgrades and assistance."
"The systems are just bulletproof. We do not have problems with it. Support for file system differences and migrations has been solid."
"Red Hat Enterprise Linux's most valuable feature is its seamless integration with Kubernetes, a powerful platform for automating the deployment, scaling, and management of containerized applications."
"RHEL is a very stable product; it's been around for a long time now and its scalability is one of the big selling points, making it as scalable as Unix and suitable for environments from a few hundred to a couple of thousand users without issues."
 

Cons

"The development teams could sharpen their skills. They should offer applications on the net."
"We have encountered some issues with the high availability clustering lately, and it seems that could use some refinement."
"My thoughts on RHEL's built-in security features are that they might be better."
"From the perspective of versions 8 and 9, one area I think Red Hat Enterprise Linux (RHEL) could improve is being careful about ABI, particularly backward compatibility."
"Red Hat Enterprise Linux (RHEL) has not helped me to mitigate downtime and lower risks."
"It would be great to have an overview of how various Red Hat products work together. They can show how to tie all those pieces together and how to have the products that we work together for our day-to-day processes."
"Red Hat Enterprise Linux should provide more training because many people are not very familiar with Linux's user interface."
"Although the security features are good, I'd like to see more added in the security sphere."
"There are performance issues with the response time when accessing the console, but I'm unsure if that's RHEL's fault or if it's due to the lack of CPU or memory on our machines. The enterprise interface could be improved. I can only use the keyboard to transfer files from one system to another. I want to use my mouse on the interface, not just scroll up and down. I would also like my logs archived as an RAR and sent to me."
 

Pricing and Cost Advice

Information not available
"We are an educational institution and as such, what we pay is less than the average company."
"Red Hat Enterprise Linux offers a straightforward pricing and licensing model."
"There are special academic offerings for academic institutes, which is pretty good. We need these offerings. In my personal opinion, the prices are okay. However, for educational purposes, they could be lower. For example, in Germany, the budget in the education sector for IT is lower compared to the huge universities in the US."
"The solution is moving away from its open source roots and licensing is a little bit of an issue."
"It's pretty expensive, but I'm not familiar with the pricing of other vendors for their operating systems. I'd rate it a seven out of ten in terms of pricing. Red Hat Enterprise Linux's main advantage is the support that you get by purchasing their subscriptions."
"The solution's price is reasonable."
"It is cost-efficient."
"I have very little experience with pricing and getting quotes. The whole VMware thing happened, and everybody is looking at different alternatives. At this point, any competitor is probably a good choice based on the cost."
