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."
"Red Hat Enterprise Linux is very stable. It has been in the market for so many years, and it is used by large organizations."
"User friendly with good compatibility."
"The most valuable aspect of Red Hat Enterprise Linux is its ease of management."
"The reliability and long support lifespan of RHEL are crucial for us. It lasts for ten years, meaning we don't need frequent changes."
"I see so many features in Red Hat Enterprise Linux that I do not see in other Linux operating systems, such as Ubuntu. That is why Red Hat is very popular"
"The reason we're using it is because it's stable and we know we can get support."
"RHEL is stable, mature, and relatively easy to handle. I'm pretty confident in it. We haven't had to raise a serious support ticket for any server in I don't know how many years."
"We run Satellite on a lot of these, so having a central repository that we can use for patch management and remote execution is huge. That's something that is very difficult in a Windows environment. We're very compliance driven, so to have that built into Red Hat is easy. We don't need an agent or anything like that to get a lot of work done, so Satellite and centralized automation are the most valuable features for us."
 

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."
"The solution should provide demos so that users can learn to use it and improve their environments."
"Red Hat Enterprise Linux (RHEL) is already good and perfect. They can continue to improve the AI features."
"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."
"There are some things that we've seen from RHEL that have given us a little bit of consternation. Their IdM product could be improved greatly."
"With Red Hat Enterprise Linux (RHEL), there's a lot of fragmentation in the documentation across different versions, and ensuring that the right version is being read can be challenging."
"Compared to Red Hat Enterprise Linux (RHEL), Ubuntu is more stable for Kubernetes and Docker-related applications."
"I'm not sure how the support is being changed in terms of needing to pay for it. That's an area that can be improved. They should offer support without charging users for it."
"Cloud licensing is confusing. We have subscriptions available to us, which is why we opted for bring-your-own-subscription. However, even then, the options make deployment difficult since we need to ensure the OS is registered to our satellite system for subscription management, not through the cloud services."
 

Pricing and Cost Advice

Information not available
"It seems to be fair. It is not overpriced."
"My company has acquired five to ten licenses from Red Hat Enterprise Linux (RHEL)."
"The pricing is fair. The workstation licensing cost is fair. If you're running enterprise-level deployments, depending on what you're using, the volume licensing is good. I personally am worried that if they get so successful, they can increase the price, and then it won't matter because we'll be stuck on them. Hopefully, their open source mentality keeps that from happening. Where it's right now is good."
"Red Hat Enterprise Linux is a more cost-effective solution than Windows Servers."
"The solution is moving away from its open source roots and licensing is a little bit of an issue."
"Pricing is something that needs to be worked out with the vendor. The more you have, the less you pay. That is the model nowadays in IT, but it is very cost-effective. You get what you pay for."
"Red Hat Enterprise Linux offers a compelling value proposition for corporations due to its robust support infrastructure, which is essential for maintaining enterprise-level systems."
"Operating in the cloud space, we typically point our customers to pay-as-you-go licensing, which comes through the various cloud providers repository services."
