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.

"Flatcar's support is good. The version I am using is stable and allows us to make needed changes."

"Red Hat Enterprise Linux is most valued for its reliability, as evidenced by my daily use."

"Red Hat Enterprise Linux has a good file system type and good kernels."

"Open architecture allows for accelerated growth while secure repositories guarantee stability."

"Red Hat Enterprise Linux is lightweight and can be run on almost anything."

"RHEL's effect on our organization's management and efficiency is noticeable because we check all the compliance boxes when we run STIG machines."

"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."

"The package management, repository, and satellite repository are easy to use."

"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."

Cons

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

"A targeted package tailored for small and medium-sized businesses can help increase business."

"As a developer, I would like to have access to this software so that I can install the tools that I need."

"The performance component is available on Red Hat Enterprise Linux, but we need to maintain the dashboard on-premises, which requires us to switch between systems instead of performing all tasks from a single location."

"While their documentation is helpful, it can be frustrating to be referred to it instead of receiving direct assistance from a support representative."

"The initial setup is pretty straightforward but can be tedious at times because of the compliance things that we have to implement."

"Red Hat Enterprise Linux has ongoing potential for improved integration with hosting solutions and VPNs as the demand for these technologies grows."

"To become more competitive, they might consider changing their licensing model, for instance, by offering an instance-based payment for cloud computing services."

"Red Hat Enterprise Linux should be available in a free version that developers could try on their own machines before deciding to implement the enterprise edition. It would be nice to have a community version available with all the features so developers can become more familiar with RHEL."

Pricing and Cost Advice

Information not available

"We are coming from CentOS, so technically, our total cost of ownership has gone up, but it is still cheaper than Windows for a database server and things like that."

"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."

"We like the model that Red Hat makes available for subscription and support. There are some free parts, subscriptions that facilitate solution development and implementation, and then, when the solution is well-defined, we move into the paid support license."

"It is cost-effective."

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

"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."

"That has been mostly handled by Red Hat. As we are a Red Hat shop, we have a lot of people around that already."

"Red Hat Enterprise Linux can be expensive, but its cost is not a deterrent for many organizations willing to invest in its stability, security, and support ecosystem."
