Room For Improvement

AlmaLinux needs better host access control, documentation, enterprise tools, hardware compatibility, support, updates, integration, and community resources.
Oracle Solaris needs improvements in hardware support, GUI, training, cost reduction, integration, package management, and open-source tool 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 firewall must be more capable because security is the main concern of every organization and every user.
Head Of IT at a financial services firm with 1,001-5,000 employees
Oracle Solaris needs to improve its compatibility with office tools like Excel.
Technology Consultant at Clarinox Technologies Kenya
Oracle is going to discontinue it, so I do not think any improvement is possible in Oracle Solaris.

Setup Cost

AlmaLinux offers enterprises a cost-effective, stable, and RHEL-compatible platform with free updates and no licensing fees.
Enterprise users find Oracle Solaris pricing complex; it's beneficial for performance but costly compared to Linux, with desired pricing improvements.
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.
I find the pricing of Oracle Solaris to be affordable compared to competitors like Windows.

Valuable Features

AlmaLinux offers enterprise-grade stability, security, and cost savings with RHEL compatibility, enhanced by TuxCare support and KernelCare integration.
Oracle Solaris offers superior virtualization, security, performance, ZFS features, and seamless Oracle integration, praised for stability and reliability.
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

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.
Shafiq Khan - PeerSpot reviewer
Head Of IT at a financial services firm with 1,001-5,000 employees
Long-term server platform has supported secure banking operations and simplified virtualization
Oracle Solaris is a very good operating system. Most of the time, we do not need to change or replace any configuration. If at any point in time we need to change something, it is really simple and a user-friendly environment. Although it is a CLI, Oracle introduced a GUI environment with Solaris 11.5. Currently, 11.5 has the operating system GUI as well as the CLI. The technical persons working on the operating system most of the time prefer to work on the CLI. It is actually really good and easy to use. As it is a server-level operating system, most of the time you do not need any extra features in the operating system because you are not using the operating system on home machines, desktops, or laptop machines. The extra features are not needed if we are talking about the enterprise level or an official operating system.
