We cut database infrastructure costs by roughly sixty to seventy percent by moving away from managed databases to using hosted PostgreSQL on Ubuntu VPS instances.
CEO at Grant Corporation
Since there are no upfront licensing fees, the ROI is increased with a scalable system without exponential cost growth.
Senior Software Developer at hireHQ
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.

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.

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.
