Empowers collaboration through streamlined integration and extensive documentation
Improving Red Hat Enterprise Linux (RHEL) can be tough, however, a significant area is collaboration tools. We have many Windows users that use Outlook and Skype or Teams to collaborate on our network. They want Linux desktops due to the fact that they want to use containers. Their biggest complaint is, 'I need two workstations to do my container work and one to collaborate.' If somehow RHEL can start introducing or collaborating with Teams and Outlook so their users can work with their Windows peers, that would be great. But I don't think that's available yet. Regarding pricing, setup costs, and licensing, there needs to be more of an education piece to it. For instance, when purchasing 10 or 100 node licenses, they could suggest, 'We also offer this 1,000 node license instead, and it'll save you specific amounts.' Just more education on their offerings would be helpful, because usually, we're coming out with the requirements, and then they just provide it to us. They could inform us about saving by bundling it differently or using alternative approaches.

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. The version I am using is stable and allows us to make needed changes."
"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 support. I primarily use the product because it offers a phone number for support when needed."
"The valuable features of Red Hat Enterprise Linux (RHEL) for on-premises are its flexibility and compatibility; it works exceptionally with JBoss."
"It is super easy to enable the tool's packages or modules when I want to start messing with it."
"Of all those Linux systems, I think RHEL is much better, but I find Ubuntu much easier to use than RHEL."
"The most valuable feature is the reliability of Red Hat's support."
"The package management, repository, and satellite repository are easy to use."
"For me, the biggest return on investment when using Red Hat Enterprise Linux (RHEL) is ease of use and quality of life."
"RHELs overall effect on our organization's management and efficiency has been good, as it is easy to support, involves no downtime, and is simple to handle, apply patches, and maintain."
 

Cons

"The development teams could sharpen their skills. They should offer applications on the net."
"The development teams could sharpen their skills. They should offer applications on the net."
"There should be more upgrades to the security features."
"Red Hat Enterprise Linux (RHEL) could be improved with a modernized knowledge base and documentation, better performance under high load, and possibly a reduction in the cost of the professional subscription."
"We have many Windows users that use Outlook and Skype or Teams to collaborate on our network. They want Linux desktops due to the fact that they want to use containers. Their biggest complaint is, 'I need two workstations to do my container work and one to collaborate.'"
"The solution's operating system configuration and function selection could be improved."
"Typically, when we open a support case with Red Hat, it is assigned to the first level of support. Even when we clearly outline the issue and request a timely response, the case often takes longer than expected to resolve."
"The solution should provide better documentation."
"Sometimes I find that Red Hat is not aligned with the rest of the world. They create their own solutions, such as Docker, Podman, Kubernetes, and OpenShift, which can be better than what others offer."
"Even though I don't have complaints, I would like them to focus even more on what they're doing with Lightspeed and the AI assistance, so they could look more into that."
 

Pricing and Cost Advice

Information not available
"Red Hat Enterprise Linux is a more cost-effective solution than Windows Servers."
"I do not know what the pricing is like now. Previously, the pricing model was advantageous as it allowed unlimited installations for a single price, focusing on support. The recent introduction of paywalls complicates the cost landscape."
"Red Hat Enterprise Linux is expensive, particularly for governments operating with limited budgets."
"The licensing is tricky to understand. Enterprises want to be beyond reproach when it comes to licensing. We would rather over-license than under-license. However, that can be complicated with a high-performance development team who may need multiple operating system instances or want to experiment with spinning up many machines to see if something works or sticks."
"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."
"It is more expensive than other vendors in terms of pricing and licensing, but because of its stability, I have to go with it."
"Most Indians will find RHEL a little costly. It's slightly above average. RHEL's pricing has room for improvement because it's more expensive in the local market due to purchasing power parity in India."
"We can always ask for Red Hat Enterprise Linux to be less expensive but when we compare it to other options, there are savings in the long run."
