Technical Solution Development Engineer at Ericsson
Enterprise workloads have run reliably while operations have reduced costs and simplified patching
AlmaLinux is already very strong, but it could be improved in a few areas. Better centralized management and monitoring, easier major version upgrades, and more enterprise-focused automation tools would make administration simpler. Having more integrated tools for patch management, compliance, configuration management, and troubleshooting could reduce manual work for system administrators. The main area for improvement is enterprise management. Better centralized patching, monitoring, compliance, and automation would make it easier to manage large-scale deployments. I would also like to see smoother and more predictable major version upgrades, especially for systems with third-party dependencies. AlmaLinux is already improving in this area through ELEvate and its migration tools.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"AlmaLinux is a very stable operating system that should definitely be considered."
"AlmaLinux offers the best features in that it is freeware for RHEL, and it is really reliable."
"Overall, I would recommend AlmaLinux because it is a stable, simple operating system with a straightforward installation process that I have found reliable so far without any glitches."
"AlmaLinux has impacted our organization positively by providing a stable and reliable enterprise Linux platform without licensing cost."
"What I especially appreciate about AlmaLinux is the long-term support, which I consider a top priority because many companies and other users need to focus on support, and I believe AlmaLinux is the best for it."
"Organizations should consider AlmaLinux if they want a stable, secure, and cost-effective enterprise Linux platform with strong RHEL compatibility."
"The most valuable feature I find in AlmaLinux is the binary compatibility with RHEL and the long-term stability, which makes it a predictable, rock-solid system behavior, while also having small and safe packaging for subsystems or systems that run twenty-four hours a day, seven days a week."
"AlmaLinux has had a positive impact on my organization because the fact that we can customize and offer clients system kernels that correspond perfectly to them, without them needing to go back over them afterward, has greatly satisfied them, and they were very happy."
"Flatcar's support is good, and the version I am using is stable and allows us to make needed changes."
 

Cons

"AlmaLinux could be improved by enhancing security and increasing speed."
"AlmaLinux could be improved by having some basic components, such as ifconfig and netstat, pre-installed on the container image, as that would be really helpful for us."
"AlmaLinux could have more software options. For example, if I need some software from Windows or something similar, it is missing some tools."
"For commercial support, enterprise-level SLAs, and dedicated assistance, AlmaLinux lists third-party commercial providers such as TuxCare, Cybertrust, and Fujitsu."
"After six months of migration, we ended up using more resources for the same websites, and that's not acceptable."
"Regarding my experience today, I installed AlmaLinux 8, and everything is okay, but the significant problem is that AlmaLinux does not ship with Wi-Fi drivers."
"AlmaLinux could be improved by addressing the slow adoption of new software and the dependency on Red Hat Enterprise Linux."
"While AlmaLinux does not provide the same vendor-backed support experience as Red Hat Enterprise Linux, the available resources are more than sufficient for many organizations and administrators."
"The development teams could sharpen their skills. They should offer applications on the net."
