Room For Improvement

AlmaLinux needs improved host access control, documentation, hardware compatibility, support, memory management, software updates, and third-party repository integration.
Debian requires improvements in package management, UI, onboarding, release cycle, network management, and better documentation to enhance user experience.
The AlmaLinux team can look into this and see what they can improve in terms of resource consumption and monitoring tools that can actually help the users of AlmaLinux pinpoint the exact processes or services that are causing that amount of resource consumption.
DevOps at a energy/utilities company with 501-1,000 employees
If something is added to AlmaLinux that allows for some subscription or makes it exactly equal to RHEL, it would be perfect.
Devops Engineer at EDAG
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.
system administration | DevOps | Softrware Developer at a tech vendor with 11-50 employees
I believe security on Debian is top-notch due to its long history and the many individuals and organizations that rely on it, meaning there are many eyes on it.

If Debian had a memory-based distribution, similar to Alpine, that would be great, as we could get benefits in terms of memory or embedded systems.
DevOps Technology Lead at TriStratus Ltd
Debian was easy to set up.
Cloud Engineer at a consultancy with 11-50 employees
 

Setup Cost

AlmaLinux attracts enterprises with its free, open-source model and cost-effectiveness, enhancing budget management and resource allocation.
Debian is cost-effective due to no licensing fees, making it ideal for enterprises compared to alternatives like Windows.
In the open-source environment, I believe a Linux distribution is always free of cost.
Junior Software Test Automation Engineer at a consultancy with 51-200 employees
AlmaLinux is free, so there are no costs there.
I have no licensing cost, which means there is no burden related to licensing.
Solution Architect at Dhanyaayai enterprise private limited
My experience with Debian's pricing, setup cost, and licensing has been that it is all free.

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.

Lightweight platform has reduced cloud costs and has kept long‑running web apps reliable
In my opinion, the best features Debian offers include its stability. The stable branch really is stable because once it is configured, I understand you can run it for a very long period of time without needing to reboot or update any of the components. That is really good when you want an application to be extremely stable and not go down, and you are happy using slightly older components. I also value the fact that Debian is open source, so it is free. That is very useful, and it has a big development community that builds it. I understand there are tens of thousands of software libraries which work with Debian from the apt package manager, APT, and also it is very lightweight, which I find to be good as well because that helps with cost savings. Debian's lightweight design benefits my organization because it does not come with bloatware, minimizing RAM usage. Because of that, we can choose cheaper EC2 instances. You do not have to have as powerful RAM, which makes things cheaper, and also because it does not come with all this bloatware, it also makes it faster. So it is very efficient. Debian positively impacts my organization by allowing us to utilize a much more lightweight operating system with Amazon EC2 instances, which greatly reduces costs because we can use EC2 instances with lower RAM. Cost savings are good. Debian is very well known across the industry, so different engineers from different teams know how to use it. Using the APT package manager is a common skill for cloud professionals, which makes it good, especially if you are hiring individuals into the company, because at least you would expect they have some type of background using Debian. I do not know exact measurements, but I would expect we could save at least 10% of costs with EC2 instances just because our memory and CPU requirements would be lower because Debian is lightweight. So it would save cost to some degree.
