ROI

Sentiment score
6.0
<p>PostgreSQL on Ubuntu offers significant cost savings and flexibility, providing 10-40% savings and enhancing R&amp;D opportunities.</p>
Sentiment score
4.6
Rocky Linux reduces costs, maintenance time, and boosts community support, leading to significant savings and resource onboarding opportunities.
Since there are no upfront licensing fees, the ROI is increased with a scalable system without exponential cost growth.
Senior software developer at Simplifyvms
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.
Specialist Programmer L3 at Infosys
If I look into the market, I have very heavy products, and even MySQL is also open source, but PostgreSQL on Ubuntu gives me a lot of savings in terms if I were to go to any other vendor which has a license.
Manager Dev Ops at a tech services company with 10,001+ employees
When it comes to return on investment, a lot of money is saved since we moved from a purchased license to the open source provided by Rocky Linux.

Room For Improvement

PostgreSQL on Ubuntu seeks optimized speed, enhanced features, and better scalability through improved tools, monitoring, and user interfaces.
Rocky Linux users seek better Kubernetes integration, faster updates, improved Windows support, and enhanced documentation for better overall experience.
Maybe it makes more sense to use AI for configuration in future updates of PostgreSQL on Ubuntu so that the database is automatically optimized for the best performance for a given hardware.

System Engineer at clusterkit
Rocky Linux could be improved by having more integration with Kubernetes.

Featured Reviews

David François - PeerSpot reviewer
Founder & Bio-IT Architect at France Farms
Creating a sovereign trust machine has secured agricultural provenance and now builds global buyer confidence
To better serve my sovereign bio-IT projects such as France Farms, PostgreSQL on Ubuntu could be improved in three key areas. First, a native GUI for hashing security management would be beneficial; while the pgcrypto extension is powerful, having a native Ubuntu-optimized graphical interface for managing cryptographic keys and audit logs would lower the barrier for non-expert administrators in the field. I have been good at this because I was really focused on getting France Farms to work, and I used my flavor of AI to assist me. Second, automated edge-to-cloud syncing would be a game-changer; a built-in lightweight tool for offline-first synchronization would be invaluable in regions such as the Caribbean, South America, or Africa, where internet connectivity can be intermittent. Having a native Ubuntu service that manages PostgreSQL on Ubuntu data syncing to AWS automatically when the connection is restored would improve the trust machine's reliability. Third, streamlined ZFS integration for data snapshots would help ensure absolute data integrity. Integrating ZFS file system snapshots directly onto PostgreSQL on Ubuntu management tools on Ubuntu would allow for transparent, instant, tamper-proof backups, giving sovereign projects an extra layer of defense against accidental data loss or hardware failure.
Massimiliano Adamo - PeerSpot reviewer
Linux architect at European Commission
Has supported seamless migrations and enabled running complex data workloads securely
The best features Rocky Linux offers include clustering and all the packages from Red Hat.Rocky Linux has impacted my organization very positively because we migrated everything from CentOS and Windows servers to Rocky Linux. Everything is clear, with good packaging, and now it's version 9.6, which is very important for us due to security problems since we are in Europe. Rocky Linux is very good for security and other aspects. Since migrating to Rocky Linux, I've seen specific outcomes such as improved security because CentOS stopped the project, and security patches aren't being released. We need to maintain a system similar to Red Hat, which is very stable and has many features such as file system, topology, and containers.
