Room For Improvement

AlmaLinux enhancements include better updates, integration, documentation, security, community support, and reduced dependency on Red Hat releases.
Docker on Ubuntu requires better documentation, security integration, and orchestration tools to overcome networking challenges and performance issues.
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
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

Enterprise users value AlmaLinux for its cost-effectiveness, GPL public license, free updates, and as a Red Hat alternative.
Docker on Ubuntu is cost-effective, focusing expenses on infrastructure while benefiting from its free, open-source nature.
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
99.9% of people will be happy with the open source version, which is open source and free.
Site Reliability Engineer Ii at a tech vendor with 5,001-10,000 employees
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 updated PHP, security, long-term support, RHEL compatibility, easy migration, cost savings, and seamless integration with cPanel.
Docker on Ubuntu offers container isolation, streamlined deployments, scalability, application consistency, cloud integration, and strong community support for development.
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

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.

Containerization has streamlined testing workflows and reduces server resources for our builds
The best features that Docker on Ubuntu offers in my experience are ease of usability and performance. Ease of usability and performance with Docker on Ubuntu have helped me because Ubuntu is a Debian-based OS that can operate in both server and desktop modes, so when using Docker on Ubuntu on a server base, I need to install a few packages to convert the machine to GUI mode, making Docker on Ubuntu easy to use. While I think security is not a standout feature, ease of usability and performance remain the main highlights for me since it's only environment-specific and involves local testing along with monitoring only internal servers. Docker on Ubuntu has positively impacted my organization through resource savings, as for our NOC server, we are using a dedicated 30-core server with 256 GB of RAM, but with the help of Docker on Ubuntu, we can run multiple containers on the same server. In terms of resource savings, we reduced the number of servers from around 100 to 70 after using Docker on Ubuntu within our private cloud, where we have numerous servers located in multiple locations in the US.
