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 has impacted our organization positively by providing a stable and reliable enterprise Linux platform without licensing cost."
"AlmaLinux offers the best features in that it is freeware for RHEL, and it is really reliable."
"AlmaLinux is a pretty fast software for handling those simulations and managing multiple jobs, and I can process my code and my simulation much faster than with Windows."
"Overall, AlmaLinux is really good, easier as well, and I do not see much difference between CentOS and AlmaLinux."
"Moreover, stable OVS networking and floating IP configuration is very easy for me when using AlmaLinux, making it a reliable and highly recommended option for teams needing an enterprise-grade Red Hat compatible workflow without the subscription cost."
"Using AlmaLinux was a condition to do my job, and right afterwards, I have been enjoying it."
"We saved approximately 70% of our budget with AlmaLinux, and the system is stable and reliable."
"AlmaLinux is better than other Linux flavors, and I recommend it for maintaining systems."
"Flatcar's support is good, and the version I am using is stable and allows us to make needed changes."
 

Cons

"If AlmaLinux could provide ten to twenty years of fixes, that would be an improvement because I do not want to update the system all the time, as it becomes more challenging for me as a system administrator to track all the patches and everything I should patch on the system."
"AlmaLinux could be improved by enhancing security and increasing speed."
"AlmaLinux could have more software options. For example, if I need some software from Windows or something similar, it is missing some tools."
"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."
"Despite being subscription-free and reliable, I find some complexities in the documentation and troubleshooting guides which are not as comprehensive as Red Hat's."
"After six months of migration, we ended up using more resources for the same websites, and that's not acceptable."
"For commercial support, enterprise-level SLAs, and dedicated assistance, AlmaLinux lists third-party commercial providers such as TuxCare, Cybertrust, and Fujitsu."
"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."
