Naim Khan - PeerSpot reviewer
DevOps Engineer at SMC Labs, LLC
Private cloud practice has become seamless and deployments run smoothly for my projects
I follow the documentation for AlmaLinux, which I believe could be more extensive for enterprise setups. My primary use case remains deploying private cloud infrastructure using OpenStack Yoga, thus suggesting improvements to cater to specific cloud instances like AWS Graviton or Azure NVMe. Driver or kernel updates for new hardware or cloud instances like AWS Graviton or Azure NVMe tend to arrive a little later in AlmaLinux than they do in the Red Hat distribution. Therefore, I suggest that faster releases of cloud-optimized images and updated hardware drivers could enhance AlmaLinux's competitiveness. Additionally, I find it sometimes difficult to find answers on forums due to the community not being as large as that of Red Hat or CentOS. My suggestion is to create an active forum or Q&A session where developers can directly address user problems, growing the community and providing optional enterprise support tiers for large organizations. Additionally, I have continued to consider improvements. For server administration and language runtime management, I encountered conflicts on production servers with older and newer versions of tools such as Python and Node.js. Simplifying the application space management would reduce the friction in multi-language development environments. Moreover, including more pre-configured or auto-remediation scripts like CIS Benchmark or STIG compliance would be immensely helpful for enterprise security hardening.

Quotes from Members

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

Pros

"We saved approximately 70% of our budget with AlmaLinux, and the system is stable and 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."
"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."
"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."
"Overall, AlmaLinux is really good, easier as well, and I do not see much difference between CentOS and AlmaLinux."
"AlmaLinux has delivered a significant positive impact on my organization through cost savings while maintaining enterprise-level reliability."
"I have seen a return on investment through significant time and money savings."
"AlmaLinux offers the best features in that it is freeware for RHEL, and it is really reliable."
"Flatcar's support is good, and the version I am using is stable and allows us to make needed changes."
 

Cons

"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."
"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."
"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."
"It is not supporting the latest hardware, so that is not good."
"I wish host access control in AlmaLinux could be made easier the way it was in CentOS because host access control was not working as expected in AlmaLinux during the initial stages."
"AlmaLinux could be improved by enhancing security and increasing speed."
"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."
"One area for improvement with AlmaLinux is the use of SELinux to secure and harden my server, which I find to be a complicated beast."
"The development teams could sharpen their skills. They should offer applications on the net."

Questions from the Community

What is your experience regarding pricing and costs for AlmaLinux?
In AlmaLinux, I do not have experience with pricing, setup cost, and licensing.
What needs improvement with AlmaLinux?
In my opinion, AlmaLinux is already very good, so I do not know if it is really necessary to improve something that already runs very well, because better is the enemy of good.
What is your primary use case for AlmaLinux?
I have been using AlmaLinux in my organization for about two years. My main use case for AlmaLinux in my company is hardening and customizing Kickstart files to have a fully customized OS for the c...
