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."

"Red Hat Enterprise Linux stands out for its stability and support, which are critical for enterprise applications in the finance sector. We don't want any downtime, so we need fast support support and quick issue resolution."

"The customer service and technical support for Red Hat Enterprise Linux (RHEL) are very responsive."

"The fact that we also use a Red Hat-based container product platform, OpenShift, means it has everything needed to run on OpenShift."

"From a security perspective, the most valuable feature is SELinux. SELinux provides good security. It's doing a good job of protecting my real estate."

"I like most of the features. I like its stability. I like its views. It provides a very stable environment."

"Red Hat Enterprise Linux (RHEL) helps me solve pain points with all the integrated tools that it brings to us, including all the Ansible Towers that we exceedingly use."

"It is a good operating system. It is very stable. It does not take a lot of maintenance. You set it up well and it runs."

"It's usually not that difficult; it's a couple of hours of work, and if any difficulties arise, it doesn't take long because we have a good community online to find solutions."

Cons

"The development teams could sharpen their skills. They should offer applications on the net."

"Sometimes it is not the relevant solution; that can happen one or two times in a year, which seems normal."

"I don't see anything that needs improvement with RHEL itself, but there is room for improvement of the support infrastructure for it. The management and updates to Satellite, which is the support update, have been cumbersome at best, including releases and changes to a release. Communication on how that will work going forward has not been great."

"From a user standpoint, every time they do an upgrade or they bring down the Linux server, I have to re-clone all my repositories."

"The solution should provide better documentation."

"Red Hat, known for its secure distribution, sometimes delays critical security patches for certain packages compared to other Linux communities like AlmaLinux or Rocky Linux."

"Red Hat Enterprise Linux's SELinux can be challenging to manage and troubleshoot, often causing frustration."

"A feature that I would like to see in the image builder is the ability to open the image in live mode and access a command line interface."

"Overall, I am happy with it, but I believe, security-wise, it could be better."

Pricing and Cost Advice

Information not available

"We purchased the Red Hat Enterprise Linux license via Azure and the vendor."

"Licensing is the most attractive part of it. With Red Hat Insights and Ansible, we now know that it was done with the intention of simplifying the licensing so that you get the support for what you have and not necessarily what you want to have."

"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."

"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."

"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."

"I do not have much knowledge of licensing. That is handled by the procurement team, but I know that it is expensive. If they can provide more licensing options, it will be much easier for companies to buy."

"Lowering the cost of enterprise-level offerings could attract organizations seeking operating systems or Kubernetes solutions, as these tools are essential for many businesses in the region."

"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."
