Oracle Solaris and AlmaLinux compete in the enterprise operating systems category. Oracle Solaris has the upper hand in security and virtualization, while AlmaLinux stands out for flexibility and cost efficiency.
Features: Oracle Solaris offers advanced security, stability, and virtualization options like LDoms and Zones, ideal for large-scale deployments. AlmaLinux provides long-term support, Red Hat compatibility, and flexibility for seamless DevOps integration.
Room for Improvement: Oracle Solaris can improve by lowering its complexity and setup cost while enhancing community support. AlmaLinux could refine its performance optimization for resource-intensive applications and enhance its graphical interface.
Ease of Deployment and Customer Service: Oracle Solaris offers a tailored deployment model with extensive vendor support, meeting enterprise needs for comprehensive service. AlmaLinux presents an easy deployment process with community-driven assistance, fitting for organizations valuing open collaboration.
Pricing and ROI: Oracle Solaris involves a higher initial setup cost but promises significant ROI through performance and uptime. AlmaLinux offers a budget-friendly setup, appealing to enterprises seeking cost-effective implementation strategies.
The clearest measurable benefit is avoiding operating system subscription costs while maintaining enterprise Linux compatibility and stability.
We saved approximately 70% of our budget with AlmaLinux, and the system is stable and reliable.
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.
In terms of ROI, there have been performance improvements because Oracle Solaris is lighter.
AlmaLinux offers strong community support and excellent documentation.
The best features AlmaLinux offers include its support, which is outstanding from TuxCare, as we are getting the fixes and patch sets for the OS very fast.
The customer support for AlmaLinux is good.
The technical support by Oracle is good.
It is very scalable and performs well both on small deployments and large-scale infrastructure with many servers.
AlmaLinux scales very well and can support everything from a small virtual machine to large enterprise deployments.
AlmaLinux's scalability is very good because the predictable updates ensure there are no issues from that point of view.
Regarding vertical scalability, Oracle Solaris is probably one of the most scalable operating systems in the industry.
Its security is another highlight, providing minimal disruptions, timely security patches, bug fixes, and a reduced attack surface.
AlmaLinux is a reliable and stable version of Linux.
It is designed for enterprise workloads and follows a long-term support model, making it suitable for production servers, databases, web applications, virtualization platforms, and cloud environments.
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.
If something is added to AlmaLinux that allows for some subscription or makes it exactly equal to RHEL, it would be perfect.
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.
The firewall must be more capable because security is the main concern of every organization and every user.
Oracle Solaris needs to improve its compatibility with office tools like Excel.
Oracle is going to discontinue it, so I do not think any improvement is possible in Oracle Solaris.
In the open-source environment, I believe a Linux distribution is always free of cost.
AlmaLinux is free, so there are no costs there.
I have no licensing cost, which means there is no burden related to licensing.
I find the pricing of Oracle Solaris to be affordable compared to competitors like Windows.
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.
Because AlmaLinux is binary compatible with Red Hat, it provides a very stable and reliable operating system suitable for production environments.
The prompt patching and OS updates with AlmaLinux have helped our team by improving our FedRAMP compliance and vulnerability scan reports.
The operating system is lightweight, which makes it easier to use on an average computer compared to systems like Windows.
Additionally, regarding security, you do not have to implement any antivirus software.
Oracle introduced a GUI environment with Solaris 11.5.
