Reliable patch management, high uptime, and incredible knowledge base
In terms of security, it does a lot of things that most people still turn off. SELinux is turned on by default. They have pretty good firewall rules in their defaults. The audit rules always take tweaking, but, overall, it comes out of the box not too bad. I used to write scripts to harden them from there. There are multiple ways to provision and patch. You have everything from local repositories to doing it by hand. Their knowledge base is incredible. There is so much information out there. It has never taken me longer than 30 minutes to find an answer to anything, even very tough ones. One company I worked for was a security company, and we did a lot of patching on everything. It was designed around security and email hosting, and uptime was pretty much whatever we wanted it to be. I have had a couple of times when the uptime was bad, but it was caused by a third-party solution. In fact, the Norton antivirus was definitely the worst. Red Hat had nothing to do with it.

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."
"The most valuable feature is the reliability of Red Hat's support."
"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."
"The tool is simple and easy to use. It has good support and doesn't have many outages due to the OS."
"It's a rock-solid operating system. We don't need anything fancy from the operating system itself. What we need is something that doesn't crash, stays up to date, and provides the security features that we need to keep external players out."
"Technical support is pretty good. It's one of the main reasons we chose Red Hat over competitors."
"It is hardware-independent. We can use Dell, HPE, or any other hardware. It is also more reasonable than the other operating systems."
"The product is super easy to use."
"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"
 

Cons

"The development teams could sharpen their skills. They should offer applications on the net."
"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 can be tricky at times, but all operating systems are. The moves to systemd and NetworkManager haven't made the product more user-friendly. Let's put it that way. The network management they had before was easier and somewhat more reliable than NetworkManager, which Red Hat forces us to use now."
"The numerous links to different pages disrupt the flow of information and make it difficult to maintain focus."
"When we initially began working with containers, we encountered some challenges with compatibility."
"I like the way the operating system works now, and I do not really see any bad functionality with it. The only thing I would say is getting rid of some aspects. That is the one part that a lot of admins probably get annoyed with."
"Red Hat Enterprise Linux analytics are cryptic."
"Some problems may occur with the product if you don't patch it after a year or two."
"Linux overall needs improvement. They cannot go much beyond what Linus Torvalds's kernel implementation can do. I come from AIX, and there were very cool things in AIX that I am missing dearly, e.g., being able to support not only adding, but also reducing memory and number of processors. That is not supported on Linux right now, and it is the same for the mainstream file systems supported by Red Hat. There is no way of reducing a file system or logical volume. Whereas, in AIX, it was a shoo-in. These are the little things where we can say, "Ah, we are missing AIX for that.""
 

Pricing and Cost Advice

Information not available
"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."
"The pricing is great for virtual systems."
"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."
"It seems to be fair. It is not overpriced."
"I like my developer account. The free sixteen licenses that they give with the developer account are great because that gives me the ability to keep using it at home instead of trying CentOS or something like that."
"We are an educational institution and as such, what we pay is less than the average company."
"The setup cost is non-existent. With licensing, there was a little snafu because I misread something. There was a slight learning curve because we use virtual data center licensing. We had to understand how it all maps. We had to understand how that mapping works when the hypervisors are Red Hat or VMware. There is a slight learning curve, but it worked out. It ends up being easy."
"Red Hat Enterprise Linux licensing is expensive."
