"With regard to security, most companies are moving towards the black box approach and Red Hat. It's much more secure compared to the other vendors.""Red Hat Enterprise Linux is very stable. It has been in the market for so many years, and it is used by large organizations.""The security of the OS is the most valuable feature.""Red Hat Enterprise Linux 9 updates the Cipher Suites and the security proceeds it. I wasn't pleasantly surprised because a bunch of our server communication didn't work. Having the Cipher Suites updated is a good thing but was not convenient.""The knowledge base offered by Red Hat Enterprise Linux is good. It is easy to parse through all of the knowledge base.""It's been great since we have it. It's been reliable and fast.""Resiliency-wise, the solution is very good.""Compared to any other product, Red Hat Enterprise Linux provides a stable backported solution for a long time."

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

More Flatcar Container Linux Cons →

"RHEL could be improved in several ways, especially regarding transparency and communication of new features.""If we can update certain parts internally without having to remove them from the entire server, that would be fantastic since, else, there will be downtime, and we will need to reboot.""If they can make the integration with Ansible easier, that would be ideal.""I would like to see additional features, including automation and the introduction of AI/ML-based tools within Red Hat to handle manual tasks that humans are required to do.""The solution is moving away from CentOS and there are growing pains from the customer's perspective.""Some of the solution's features need to be automated. We encounter the hassle of registering the system and attaching a subscription.""The Cockpit interface needs improvement with more features. The information for implementing Red Hat Cluster could be also improved. And there could also be better performance monitoring.""We need to have more flexibility on the developed versions. Not everybody is ready to subscribe to enterprise versions. They would like to test the tool without subscriptions."

Pricing and Cost Advice
Information Not Available
  • "The pricing is a bit on the expensive side, mainly because of the support they provide. However, it is quite affordable if you are an organization. If, as a small company or individual, this is an expensive option, I would recommend CentOS, which is an exact replica of RHEL, minus the customer support."
  • "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."
  • "Red Hat Linux is inexpensive. Linux solutions are generally inexpensive."
  • "RHEL is expensive."
  • "Because it is a subscription, you can go elastic. This means you can buy a year, then you can skip a year. It is not like when you buy something. You don't buy it. You are paying for the support on something, and if you don't pay for the support on something, there is no shame because there are no upfront costs. It changes the equation. However, we have such growth right now on the Linux platform that we are reusing and scavenging these licenses. From a business standpoint, not having to buy, but just having to pay for maintenance, changes a lot of the calculations."
  • "We have a site license on a yearly basis. Generally, we're okay with its price, but everything could be cheaper."
  • "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."
  • "We are an educational institution and as such, what we pay is less than the average company."
