In terms of outcomes or benefits I've seen over the last year, we have more than 30 servers, and we only need to reboot one server while all other servers continue working fine, resulting in very low downtime, which is very helpful.
System Engineer at Reve Systems
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.

Managed platform has reduced our operations workload and delivers faster cluster startups
I wouldn't say it's specifically an Oracle Linux pro, but when using Oracle Linux with a Kubernetes engine, it provides you with all the necessary libraries that it needs for a startup. This means quicker startup time and quicker joining to the cluster. It's just fast when you use Oracle Linux because it's optimized for your OKE engine. When I mention quicker startup time and easier joining to the cluster, it means you have a pretty good startup when you want to scale, you don't have to wait longer times just for your nodes to come up. When you have your traffic spiking, you don't want to wait that two to three minutes extra for a node to join the cluster, so that's where you have that advantage. And even for the customers when we give them access, it's a better startup since it's optimized and has all the necessary libraries. When I mention our workload is reduced because it's managed and optimized, it is approximately 80 to 90 percent of our workload is reduced because Kubernetes also releases frequent updates. You don't have to migrate to a new one; when you're migrating, it's pretty quick. All the security patches are handled by Oracle. The newer updates are provided by Oracle, and you don't have to test it. You will need to do some rounds of testing, but way less than managing your own Linux.
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.
