Room For Improvement

AlmaLinux needs better host access control, documentation, enterprise tools, hardware compatibility, support, updates, integration, and community resources.
Windows Server needs improved security, stability, cloud integration, simpler UI, better pricing, easier configuration, and broader compatibility support.
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
The support team is getting worse in terms of expertise.
Manager, IT Security at Averis Sdn Bhd

Team Manager at Waters Corporation
 

Setup Cost

AlmaLinux offers enterprises a cost-effective, stable, and RHEL-compatible platform with free updates and no licensing fees.
Enterprise users find Windows Server costly and complex to license, preferring simpler, more competitive pricing compared to Linux.
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.
On a scale of one to ten, with ten being the most expensive, I rate it ten out of ten.
Manager, IT Security at Averis Sdn Bhd
Microsoft offers product pricing with licenses per processor and CAL licenses for accessing.
Manager, Information & Cloud Systems at a consultancy with 1,001-5,000 employees
The cost associated with Windows Server—considering pricing, licensing, and setup—is expensive, no doubt.
Executive Vice President Technology at InfoEdge India Ltd
 

Valuable Features

AlmaLinux offers enterprise-grade stability, security, and cost savings with RHEL compatibility, enhanced by TuxCare support and KernelCare integration.
Windows Server excels in integration, ease of use, security, scalability, and supports enterprise applications with features like Hyper-V and PowerShell.
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.

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
I can manage the firewalls on the server easily, open or close ports to manage security traffic, and use encryption on the hard disk to keep data secure.
Systems technician. IT Office at LNU

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.

IT at a retailer with 11-50 employees
Centralized controls have improved security and simplify user management across our environment
One area where Windows Server could be improved is in simplifying administration and troubleshooting. While Windows Server is powerful, diagnosing issues related to group policy, DNS, replication, and authentication can sometimes be complex and time-consuming. I would prefer to see more intuitive management dashboards, better built-in monitoring and reporting tools, and integration with cloud service-enhanced automation features for routine administrative tasks. This would further reduce manual effort and improve efficiency. Overall, Windows Server is a reliable platform, but making management and troubleshooting more streamlined would help IT teams save time and improve productivity. Another area for improvement is documentation and update management. While Microsoft provides extensive documentation, finding the most relevant troubleshooting information can sometimes be challenging for complex issues involving Active Directory, DNS, or group policy. Updates are important for security, but some updates require careful testing and planning to avoid unexpected impacts on production environments. More detailed pre-update impact analysis and simplified rollback options would be beneficial. Overall, Windows Server is a robust platform, but improvements in documentation, troubleshooting guidance, update management, and administrative automation would further enhance the experience for IT professionals.
