ROI

Sentiment score
4.7
Organizations saved costs and time with AlmaLinux due to its free RHEL compatibility, stability, and reduced vendor lock-in.
Sentiment score
7.0
Debian's open-source platform cuts costs by eliminating fees, supporting less powerful hardware, and enhancing efficiency with minimal downtime.
The clearest measurable benefit is avoiding operating system subscription costs while maintaining enterprise Linux compatibility and stability.

We saved approximately 70% of our budget with AlmaLinux, and the system is stable and reliable.
Systems Engineer at SARL Rajafood
Moving over to AlmaLinux saves a lot of time because of the long-term support, meaning I do not have to support the latest version every couple of years.
There were direct cost savings since Debian has no licensing fees, and we did not require paid support, so it saved us considerable money.

Room For Improvement

AlmaLinux needs better host access control, documentation, enterprise tools, hardware compatibility, support, updates, integration, and community resources.
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.
Founder at a media company with 1-10 employees
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 offers enterprises a cost-effective, stable, and RHEL-compatible platform with free updates and no licensing fees.
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 itself is free and open-source, so there is no OS licensing fee.
Technical Solution Development Engineer at Ericsson
AlmaLinux is free, so there are no costs there.
My experience with Debian's pricing, setup cost, and licensing has been that it is all free.
IT Support Manager at a educational organization with 5,001-10,000 employees
My experience with pricing, setup cost, and licensing is that Debian is free, so there is no price.
SRE II at a tech vendor with 5,001-10,000 employees
As long as I remain within the limit of that credit, I can create machines as much as I want without exceeding the monthly limit.
Cybersecurity Engineer at a tech consulting company with 51-200 employees
 

Valuable Features

AlmaLinux offers enterprise-grade stability, security, and cost savings with RHEL compatibility, enhanced by TuxCare support and KernelCare integration.
Debian delivers stability, performance, and security with vast support and resources, ideal for enterprise environments and web services.
The tooling stability for DevOps is also significant, allowing easy use of infrastructure as code with Ansible or scripting playbooks that remain valid for years, making it especially important for the CI/CD pipelines.
system administration | DevOps | Softrware Developer at a tech vendor with 11-50 employees
Because AlmaLinux is binary compatible with Red Hat, it provides a very stable and reliable operating system suitable for production environments.
Ingénieur Systéme at Groupe Open SA
At this moment, AlmaLinux is a very open platform. It not only includes the latest security patches but also integrates very recent AI technologies alongside the direct patches that help harden the server.

Arka A - PeerSpot reviewer
Technical Solution Development Engineer at Ericsson
Enterprise workloads have run reliably while operations have reduced costs and simplified patching
AlmaLinux is already very strong, but it could be improved in a few areas. Better centralized management and monitoring, easier major version upgrades, and more enterprise-focused automation tools would make administration simpler. Having more integrated tools for patch management, compliance, configuration management, and troubleshooting could reduce manual work for system administrators. The main area for improvement is enterprise management. Better centralized patching, monitoring, compliance, and automation would make it easier to manage large-scale deployments. I would also like to see smoother and more predictable major version upgrades, especially for systems with third-party dependencies. AlmaLinux is already improving in this area through ELEvate and its migration tools.

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.
