Reliable long-term hosting has reduced server migrations and lets me focus on projects
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. Better documentation on that part could be useful, although there is a lot of material out there. I choose a nine because nothing is ever perfect. For example, coming from Ubuntu, I found their firewall software easy to use, while with AlmaLinux's entire ecosystem, I always have to look up how to use firewall-cmd. These are just little preferences. I cannot think of anything else AlmaLinux could improve; it serves me well, and I have not been missing anything.

Has supported reliable deployments and simplified issue resolution in complex environments
The most suitable feature of CentOS is its exceptional stability, security, and long-term support, which make it a popular choice for enterprise and server environments. CentOS is widely recognized for providing a stable and secure platform, especially suited for server and mission-critical workloads. Whenever we face critical work, it is easy for our team to handle. For long-term support, each CentOS release generally guarantees long-term updates, ensuring reliability for extended periods. For package management, we use YUM and DNF in the new version for flexible and efficient software management. It depends on our users' requirements for installing CentOS. Licensing for CentOS is above my management details, so I am not aware of this information. CentOS always provides good feedback, is easy to handle, and easy to troubleshoot. The experience with CentOS OS has been very good over the last two months. I rate CentOS nine out of ten.

Quotes from Members

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

Pros

"AlmaLinux provides free updates and security, unlike Red Hat, where support must be purchased separately."
"AlmaLinux has impacted our organization positively by providing a stable and reliable enterprise Linux platform without licensing cost."
"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."
"The long-term support provided by AlmaLinux helps my business by ensuring that we do not have to renew our servers every four to five years."
"Positively, I can say that AlmaLinux has brought a sense of stability, and besides the security patches, we also noticed better virtualization for our use cases."
"The open architecture is useful for us. That's why we're using CentOS."
"The solution is open source."
"The product is free to use."
"We particularly like that we can remove the graphic user interface to minimize attack settings for the operating system."
"The most valuable feature is performance."
"Its performance is most valuable. There is a performance boost as compared to when the applications are run on Windows OS."
"I like how you can alternate certain things and minimize admin features on there and just let it run on specific scripts. It's nice. Even if I had to put it in a container, I'd still do it. I prefer Linux over Windows any day."
"The most suitable feature of CentOS is its exceptional stability, security, and long-term support, which make it a popular choice for enterprise and server environments."
 

Cons

"After six months of migration, we ended up using more resources for the same websites, and that's not acceptable."
"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."
"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."
"Previous versions were unstable."
"The solution’s stability could be improved."
"The product lacks a graphical user interface that can help users automate certain systems using the native features offered by CentOS."
"CentOS could be improved by being more secure. Of course, we use a firewall, but security is always a concern."
"The solution could be more scalable."
"The security could be improved because the server system isn't very secure."
"Integration with Open Stack could be improved."
"The solution might be discontinued but I hope that IBM will continue to develop it and improve on the functionally and features."
