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

ROI

Sentiment score
5.0
AlmaLinux offers cost savings, reduces security risks, and provides long-term support without licensing fees, increasing operational efficiency.
Sentiment score
4.6
Organizations experienced improved operational efficiency through faster CI/CD, cost-effective storage, and streamlined container management with Docker on Ubuntu.
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.

AlmaLinux impacts an organization by helping you understand when there are errors or flaws that you need to mitigate by providing you the logs.
Cloud Security Engineer at Andela
The main return is time-saving, as it provides less setup time, fewer errors, and improved developer productivity.
DevOps at Chill Flow
You need some type of operating system and a container engine, and these two are best in class.
Cloud Ops Lead at a tech vendor with 10,001+ employees
There is a pipeline for it, and the time saving occurs because whenever a developer pushes anything, that goes into the Docker container and builds it.

Scalability Issues

Sentiment score
4.4
AlmaLinux is praised for efficient scalability and adaptability, seamlessly integrating servers without architecture changes, satisfying diverse user needs.
Sentiment score
5.6
Docker on Ubuntu provides scalable deployment with Docker Compose/Swarm, but complex needs may require Kubernetes, affecting suitability and costs.
It is very scalable and performs well both on small deployments and large-scale infrastructure with many servers.
Ingénieur Systéme at Groupe Open SA
In some cases, Docker on Ubuntu is not enough for all the complexity of the applications, and I have to go to the next level with Kubernetes.
Founder at Asynka
Ubuntu is very stable as an operating system, and Docker scales well when used properly across projects and environments.
DevOps at Chill Flow
Using Docker on Ubuntu together is a common configuration, and you can deploy it directly on server hardware using virtual machines or in the cloud, scaling however you wish.

Stability Issues

Sentiment score
8.5
AlmaLinux is stable, reliable, ideal for production with minimal disruptions, timely security patches, and excellent long-term performance.
Sentiment score
8.1
Docker on Ubuntu is stable and reliable, with some version-related delays; users report smooth Amazon Cloud deployment.

DevOps Engineer at Elevenxcapital
 

Room For Improvement

AlmaLinux users seek prompt TuxCare updates, improved docs, better cloud support, efficient resource use, and enhanced monitoring tools.
Docker on Ubuntu needs a GUI and simplified features to ease complexity and improve user experience for beginners.
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 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
Code sharing ability exists in GitHub and other tools, but in Docker on Ubuntu, other users we are sharing with do not have options like edit and update the code.
Software Engineer at INSTITUTE OF AERONAUTICAL ENGINEERING
While Docker itself has no cost, the Docker repository and Docker Hub could improve their pricing, especially for startup companies.
Chief Technology Officer at ML Cloud LLC
It is completely complex to understand the networking in Docker on Ubuntu and Kubernetes clusters, as well as the ephemeral nature of the network and storage.
Founder at Asynka
 

Setup Cost

AlmaLinux is a free, open-source alternative to Red Hat, offering cost-effective enterprise solutions with no licensing fees.
Docker on Ubuntu is cost-effective, mainly requiring skilled personnel, with the free version meeting most enterprise needs efficiently.
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.
Currently, we have not experienced pricing with AlmaLinux, as I have used the free version so far.
DevOps Engineer at SMC Labs, LLC
99.9% of people will be happy with the open source version, which is open source and free.
SRE at Akamai
I find the pricing for Docker on Ubuntu is not expensive because basically, it is zero.
Founder at Asynka
Docker does not have licensing.
Cloud Operations Engineer at a tech vendor with 51-200 employees
 

Valuable Features

AlmaLinux offers stability, enterprise support, and compatibility, benefiting organizations with reduced costs, compliance, and high-performance infrastructure.
Docker on Ubuntu offers efficient container management, seamless integration, cost-efficiency, and enhanced productivity with consistency and portability.
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
The prompt patching and OS updates with AlmaLinux have helped our team by improving our FedRAMP compliance and vulnerability scan reports.

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.

Built a reliable cloud foundation that has supported flexible web applications and smooth scaling
Docker on Ubuntu can be improved because Ubuntu is not minimalist at all; it comes with a lot of software by default. This has led some individuals, including myself, to try using Alpine, which is more lightweight, allowing the container to run on a more lightweight operating system that potentially uses fewer resources and reduces costs. If Ubuntu were a little more minimalist, that would be good, but it's not really aiming for that since it intends to be the baseline. Also, Ubuntu moves very fast, possibly faster than other operating systems like Debian, which could demand operational heavy upgrades to major versions every couple of years if there are many applications running.
