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
4.6
Companies achieve cost and time savings with Docker on Ubuntu via faster builds, deployments, and reduced storage and resource needs.
The clearest measurable benefit is avoiding operating system subscription costs while maintaining enterprise Linux compatibility and stability.
Associate Systems Engineer at Dhanyaayai Enterprises Pvt Ltd
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.
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.
Senior Dev Ops Engineer at 11 East Capital
 

Customer Service

Sentiment score
5.5
AlmaLinux offers strong community support and third-party assistance, differing from RHEL, with variable response times and effective solutions.

Senior Dev Ops Engineer at 11 East Capital
 

Room For Improvement

AlmaLinux needs better host access control, documentation, enterprise tools, hardware compatibility, support, updates, integration, and community resources.
Docker on Ubuntu requires UI, networking, and storage simplifications with improved documentation, security, and Kubernetes integration.
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

AlmaLinux offers enterprises a cost-effective, stable, and RHEL-compatible platform with free updates and no licensing fees.
Enterprise users find Docker on Ubuntu cost-effective, with potential expenses mostly related to staff training and infrastructure.
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.
99.9% of people will be happy with the open source version, which is open source and free.
SRE 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 enterprise-grade stability, security, and cost savings with RHEL compatibility, enhanced by TuxCare support and KernelCare integration.
Docker on Ubuntu enhances scalability, efficiency, and deployment with process isolation, portability, YAML configuration, and strong community support.
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.
DevOps Engineer at SMC Labs, LLC
Docker is the heart of many AI tools that are used, and I have an AI workstation that uses Docker to package up certain capabilities for AI engineering.
Chief Technology Officer at ML Cloud LLC
The best features that Docker on Ubuntu offers are container isolation, fast startup time, portability, and strong integration with the Ubuntu Linux ecosystem, making it easy to package applications with their dependencies and run them consistently across systems.
embedded software engineer at a manufacturing company with 201-500 employees
Docker on Ubuntu has positively impacted my organization by making our CI/CD pipeline faster because of the multi-stage build, multi-arch build, and the strategy of layering.

Featured Reviews

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.
AnilKumar13 - PeerSpot reviewer
Devops Engineer at EDAG
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.
