While Docker itself has no cost, the Docker repository and Docker Hub could improve their pricing, especially for startup companies.
Chief Technology Officer at ML Cloud LLC
It is completely complex to understand the networking in Docker on Ubuntu and Kubernetes clusters, as well as the ephemeral nature of the network and storage.
Founder at Asynka
For large environments, scaling Nagios Core on CentOS requires additional architectural planning, and tuning alerts is critical; otherwise, teams start ignoring notifications.
Senior HPC Engineer at a energy/utilities company with 10,001+ employees
The learning curve for new users adopting Nagios Core on CentOS is challenging, primarily due to the limited documentation available on the internet regarding how to install and maintain it.

Devops Engineer at EDAG
Containerization has streamlined testing workflows and reduces server resources for our builds
The best features that Docker on Ubuntu offers in my experience are ease of usability and performance. Ease of usability and performance with Docker on Ubuntu have helped me because Ubuntu is a Debian-based OS that can operate in both server and desktop modes, so when using Docker on Ubuntu on a server base, I need to install a few packages to convert the machine to GUI mode, making Docker on Ubuntu easy to use. While I think security is not a standout feature, ease of usability and performance remain the main highlights for me since it's only environment-specific and involves local testing along with monitoring only internal servers. Docker on Ubuntu has positively impacted my organization through resource savings, as for our NOC server, we are using a dedicated 30-core server with 256 GB of RAM, but with the help of Docker on Ubuntu, we can run multiple containers on the same server. In terms of resource savings, we reduced the number of servers from around 100 to 70 after using Docker on Ubuntu within our private cloud, where we have numerous servers located in multiple locations in the US.

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.
