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 secure application hosting and reliable server management
I find the GUI to be good in Ubuntu Linux, and I appreciate the open SSH. The fact that it is free since it is open and open-source is why I appreciate it and feel it is secured. We have multiple different kinds of support related to Ubuntu Linux, including official support and other options. I am currently using laptops, desktops, and servers, and Ubuntu Linux supports all these devices. If I need it for Raspberry Pi or something similar, I can download another Linux distribution. Ubuntu Linux is scalable, especially for servers. We prefer using Ubuntu Linux Servers rather than Windows. The biggest advantage of Ubuntu Linux for me is that it is open-source, secured, and scalable.

Quotes from Members

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

Pros

"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 provides free updates and security, unlike Red Hat, where support must be purchased separately."
"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 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."
"AlmaLinux has impacted our organization positively by providing a stable and reliable enterprise Linux platform without licensing cost."
"Linux-based operating system with good stability, good patching, and a straightforward setup."
"It is a widely used and stable solution. Community members can offer support and technical guidance."
"Since Ubuntu is freely available for download and use, there is virtually no investment required, resulting in a high ROI."
"My total rating for Ubuntu Linux is ten out of ten."
"It is fast and easy to install. It also supports containers and all kinds of libraries. I can do almost everything with it."
"The solution is stable, fast and free."
"You can scale the solution quite well."
"The solution is user-friendly."
 

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."
"The only improvement I would suggest is to switching back to Aptitude. They switched a lot of the packages that used to be running in Aptitude to Snap. I don't find them as usable when they are in Snap. The most obvious instance of this is that it's caused me to have issues with Chrome. Starting Chrome took a couple of seconds before it was up and running, which wasn't pleasant. Back when it used to run packaging in Aptitude, I didn't have this problem. I know they're familiar with these issues because a lot of other people have experienced them too."
"I want more insights and security features in the pro version, specifically activities and vulnerabilities. When releasing a new version, it's crucial to ensure no vulnerabilities. Sometimes, a new version may have minor vulnerabilities, like one medium and one low. These typically take about two weeks to resolve. More regular patching, especially addressing security vulnerabilities, is essential to improve."
"On the GUI, when I use SSH or PuTTY or what is called a console port to connect with the network devices or servers, it is somehow difficult compared with Windows."
"The solution could be more stable and secure."
"Ubuntu Linux could improve by having more out-of-the-box functionality for common plug-and-play devices, such as printers. It's sometimes more difficult to plug-and-play printers with Ubuntu Linux. You need to work a bit and make some drivers work. They need to work a bit on plug-and-play devices."
"It could be easier for beginners and the user interface could be more user-friendly."
"The solution could improve by being more user-friendly, you need to know how to use the command-line interface which you might not understand."
"An easier to configure firewall would be a good add-on."
