Since there are no upfront licensing fees, the ROI is increased with a scalable system without exponential cost growth.
Senior software engineer at Simplify vms
Think about if you are in a different geographic location and your cluster is hosted in two different geographic locations, maybe one in South Pacific and one in Western Europe. In both cases, if write transactions are happening, this is a good way to basically order the transactions so that the eventual data consistency is there.

Room For Improvement

AlmaLinux needs better host access control, documentation, enterprise tools, hardware compatibility, support, updates, integration, and community resources.
PostgreSQL on Ubuntu requires enhanced performance, ease of setup, AI integration, intuitive UI, scalability, and better documentation.
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
PostgreSQL on Ubuntu is very stable in terms of performance and query optimization.
Software Engineer at a university with 501-1,000 employees

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.

CEO at Grant Corporation
Consistent use of flexible data and solid transactions has reduced costs and simplified projects
PostgreSQL on Ubuntu could be improved with easier out-of-the-box configuration. The default settings for PostgreSQL on a fresh Ubuntu install are very conservative. Things such as shared buffers and work memory are too low for any real production workloads, and you have to know how to go in and tune it manually. A smart default configuration wizard during installation that detects hardware and suggests settings would save a lot of junior developers from performance headaches. That is important. Built-in connection pooling is another area; PostgreSQL does not handle large numbers of concurrent connections well natively. You end up needing to set up PG Bouncer separately, which is another tool to learn, configure, and maintain. Having a lightweight connection pooler built into the core installation would be a real quality-of-life improvement. Additionally, a better built-in monitoring UI would help. Primarily, if you are working with Ubuntu, you are largely working with PostgreSQL on the command line and installing third-party tools such as pgAdmin or Adminer. A lightweight built-in web dashboard for basic health monitoring would improve projects significantly. Finally, upgrades between major versions and smaller versions should be a lot easier as well. None of these are deal-breakers; they are just nice to have improvements.
