AlmaLinux 9 (Alma Linux 9) | Hardened by ProComputers

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 client. A concrete example of how I customize these Kickstart files with AlmaLinux to meet the needs of a particular client is that I modify the Kickstart file by adding lines to remove applications and to automate the download and installation of certain other applications on AlmaLinux, so that as soon as it is deployed, the applications are already installed.

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.

This impact has translated into time savings for my organization because once I master customization, I know what to change and modify. Then I regenerate the kernel and then redeploy, and it goes quite fast. This saves time and allows me to be much more efficient. Of course, I first go through a testing phase before redeploying at the clients'.

In my opinion, the best features that AlmaLinux offers are the fact that I can customize it using the Kickstart files and have very comprehensive documentation on the vendor's website that allows me precisely to completely customize it the way I want.

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.

I have been working in my current field for about ten years.

AlmaLinux seems very stable for my use cases.

Regarding the scalability of AlmaLinux, I find that for now, I have not had the opportunity to evaluate scalability, but I think that if I had to do it, I would not be disappointed; I would be very satisfied compared to everything I have already seen with AlmaLinux. For me, it is a mark of quality.

I rate AlmaLinux's customer support as good because for now, I have not yet had the opportunity to deal with customer support, because everything I have had to do has worked very well. When it did not necessarily work the first time, it was enough to just reread the documentation properly with a clear head and then the problem was resolved.

Before choosing AlmaLinux, I evaluated other solutions, specifically we were on Red Hat 7, and given the security vulnerabilities and the obsolescence of the old distribution, the team leader decided to move us to AlmaLinux.

I have seen a return on investment thanks to AlmaLinux, specifically time savings, but I do not have access to economic indicators, since I only handle the system side; it is more the people on the commercial side who could provide such indicators.

My advice to other professionals who are considering using AlmaLinux is to go for it without asking themselves questions, because all the necessary support is there to start from scratch and manage to do great things with it. Tutorials, documentation, and forums are all available and represent a very good thing. I rate this review as a nine out of ten.

I use AlmaLinux to create simulations, Monte Carlo simulations using C++, and for that I need to use the terminal and put a lot of different jobs to process the code.

AlmaLinux is a pretty fast software for handling those simulations and managing multiple jobs. I can process my code and my simulation much faster than with Windows. AlmaLinux is good to work on folders using the terminal, and if I can change something inside the operational system, I have the ability to do that.

I prefer AlmaLinux because it is free and open. I can change anything in AlmaLinux if I want to. If I need to modify code, multithread, or other elements, I can do that with the flexibility that AlmaLinux offers.

With AlmaLinux, I can use the CERN infrastructure. I can use the server from CERN, and CERN has used AlmaLinux since 2024. They installed it recently. It is fast, and Linux is better for coding in C++, Python, and other languages. If you need to manage data, it is considerably better. If I need to process code, AlmaLinux will be two times faster than Windows, for example, which is a specific outcome since switching.

AlmaLinux could have more software options. For example, if I need some software from Windows or something similar, it is missing some tools.

I would say you cannot assume AlmaLinux is so similar to Ubuntu. If you use Ubuntu, you can find some difficulties using AlmaLinux.

I have been working in my current field since 2021.

AlmaLinux is stable.

The scalability of AlmaLinux is good.

I worked with AlmaLinux and shared it with a lot of people. The customer support was good.

I did not use the customer support myself, but I have a friend who used it and he said it is an eight.

I did not use a different solution before choosing AlmaLinux.

I just use AlmaLinux for science, and science does not aim toward money, so I have not seen a return on investment.

I did not take the decision. I just used AlmaLinux because CERN was using the server.

In AlmaLinux, I do not have experience with pricing, setup cost, and licensing.

I did not use a different solution before choosing AlmaLinux.

I do not understand about AI capabilities when I relate this to AlmaLinux governance and security.

I do not know about the accuracy and reliability of AlmaLinux output.

I do not think there are any improvements needed for AlmaLinux that I have not mentioned yet.

AlmaLinux is primarily used for running stable server workloads and enterprise Linux environments. Since it is binary compatible with Red Hat Enterprise Linux, it provides a reliable platform for hosting applications, web servers, databases, and infrastructure services without subscription costs.

I deployed a web application environment consisting of Apache, a database server, and automation scripts using AlmaLinux. The RHEL compatibility allowed me to follow enterprise Linux best practices while avoiding licensing costs. I also used AlmaLinux for Kubernetes and container-related labs because it provides a stable operating system foundation similar to enterprise Linux environments.

AlmaLinux offers several standout features that I have observed during my usage, including long-term stability, RHEL compatibility, being free and open source, providing regular security updates, and community governance.

The most valuable feature for me is RHEL compatibility. It allows for the use of the same tools, packages, and administration practices found in enterprise Linux environments while avoiding subscription costs. This is especially useful for learning, testing, and infrastructure deployments. RHEL compatibility reduces troubleshooting and configuration effort because extensive documentation and a large knowledge base are available. Administrators can follow well-established enterprise Linux procedures, reducing the likelihood of configuration errors.

AlmaLinux has delivered a significant positive impact on my organization through cost savings while maintaining enterprise-level reliability. AlmaLinux provides a stable server platform without operating system licensing fees, allowing organizations to allocate resources elsewhere.

The main improvements I would suggest are expanding enterprise awareness, growing the commercial support ecosystem, and providing additional onboarding and migration resources. AlmaLinux itself is stable, secure, and reliable. Most opportunities are around ecosystem growth and user adoption rather than technical limitations. The biggest improvements I would like to see include stronger enterprise ecosystem support, more commercial support options, additional migration tools, and increased industry recognition.

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. Overall, AlmaLinux is highly rated, but the ecosystem and support aspects could be expanded.

I have been using AlmaLinux for more than six to seven months.

AlmaLinux is highly stable and represents one of its strongest qualities. It is designed for enterprise workloads and follows a long-term support model, making it suitable for production servers, databases, web applications, virtualization platforms, and cloud environments.

AlmaLinux scales very well and can support everything from a small virtual machine to large enterprise deployments. It works effectively in physical, virtualized, cloud, containerized, and clustered environments. I would rate AlmaLinux highly for scalability.

AlmaLinux offers strong community support and excellent documentation. While it 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.

I did not use any other solution before AlmaLinux. I did not evaluate any other options. I was completely focused on AlmaLinux and had my eye on AlmaLinux, so there were no alternative options considered.

The return on investment comes primarily from lower operating system costs, operational consistency, and reduced administrative effort. Even without exact metrics, the impact is reflected in cost savings from licensing, faster deployments through RHEL compatibility, and a stable platform that supports reliable operations. The clearest measurable benefit is avoiding operating system subscription costs while maintaining enterprise Linux compatibility and stability.

AlmaLinux is highly rated overall. I would advise you to seriously consider AlmaLinux if you are looking for a stable, enterprise-grade Linux distribution without operating system licensing costs. It provides excellent compatibility with the Red Hat ecosystem, making it a strong choice for servers, cloud deployments, virtualization, containers, and enterprise applications.

AlmaLinux scales very well and can support everything from a small virtual machine to large enterprise deployments. It works effectively in physical, virtualized, cloud, containerized, and clustered environments. I would rate AlmaLinux highly for scalability.

AlmaLinux's role is seen as enabling governance and security rather than directly governing AI. Its enterprise security features, long-term support, auditing capabilities, and stable operating environment help organizations run AI workloads securely and in a controlled manner. AI governance itself is typically implemented through higher-level tools, policies, and processes.

I would not rate AlmaLinux on AI output accuracy because that is determined by the AI application itself. However, I would rate AlmaLinux highly for reliability as a platform for AI workloads because it provides enterprise-grade stability, security, and long-term support.

Based on my experience using AlmaLinux, I do not believe there are any other improvements needed. I would give this product a rating of nine out of ten.
