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

ROI

Sentiment score
4.4
Organizations using AlmaLinux benefit from cost savings, efficient management, long-term support, and positive investment sentiment despite limited metrics.
Sentiment score
7.0
Debian's open-source platform cuts costs by eliminating fees, supporting less powerful hardware, and enhancing efficiency with minimal downtime.
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.
The most immediate benefit has been the elimination of licensing and subscription fees compared to commercial enterprise Linux distributions or Windows.

Room For Improvement

AlmaLinux users face challenges with support, documentation, updates, resource allocation, and integration, seeking improvements in security and package availability.
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.

If something is added to AlmaLinux that allows for some subscription or makes it exactly equal to RHEL, it would be perfect.
Azure Dev Ops Engineer at a engineering company with 5,001-10,000 employees
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.

Setup Cost

Enterprise users find AlmaLinux cost-effective for budget management, offering free setup, support, and updates as an open-source alternative.
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.
Open Shift Engineer at Dhanyaayai enterprise private limited
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.

Valuable Features

AlmaLinux improves PHP management, ensuring stability, security, and cost efficiency with RHEL compatibility, ideal for production environments.
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.

Featured Reviews

Naim Khan - PeerSpot reviewer
DevOps Engineer at SMC Labs, LLC
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.
Badal Shrivastav - PeerSpot reviewer
Embedded Linux / BSP Engineer at Veethree
Reliable platform has supported long-term on-prem deployments and predictable OTA updates
If I consider how Debian can be improved, it could be more accessible in making newer software versions available for users who need recent features while still maintaining default stable behavior. While backports help, the workflow could be streamlined. The release cycle can feel slow for rapidly evolving tools, and better guidance around mixing stable, backports, and testing would help. Regarding hardware support, Debian can be improved by supporting multiple BSPs, making it more versatile in the embedded domain. Hardware support for new devices can sometimes lag behind, which is understandable given Debian's focus on stability. Clearer guidance on handling newer hardware or firmware would be beneficial.
