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.

Infrastructure Analyst at a tech vendor with 10,001+ employees
Monitoring has reduced outages and improves proactive issue resolution across our infrastructure
Regarding complexity, I think there is no feature like InfluxDB AI, so it may require more expertise to configure. There are also some migration challenges in adopting the new dashboards, so it takes some time to train the staff, but it is not a big concern. I think it is better to add some advanced features. I do not think there are so many things that need to be improved in Nagios Core on CentOS. If it is better to customize the dashboard or if we can get something like a modern view, it will be helpful for the dashboard. I felt very happy with Nagios Core on CentOS. Why I took off one point is that I think it is better suited for a small or medium setup. If large enterprises can use Nagios Core on CentOS, it will be helpful. It also requires manual editing of the config file, so it is a little bit time-consuming. The web interface is functional, but compared to some other latest AI monitoring platforms, it is a little bit lacking. I think the AI platform would score higher, but it is good. The reporting is just basic, so if we compare it with Grafana, it needs richer insights.

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.
