Room For Improvement

Docker on Ubuntu requires UI, networking, and storage simplifications with improved documentation, security, and Kubernetes integration.
AI-enhanced optimization, compatibility updates, and deployment improvements are crucial for MariaDB on CentOS amidst repository management challenges.
Code sharing ability exists in GitHub and other tools, but in Docker on Ubuntu, other users we are sharing with do not have options like edit and update the code.
Software Engineer at INSTITUTE OF AERONAUTICAL ENGINEERING
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
Postgres is easier to work with because you can use the explain plan to see directly and immediately if your new request is good or not.
Performance Testing And A PM Expert at ADM
For potential improvements that could be made in the future for MariaDB on CentOS, I think two or three things are needed; one is AI to support rewriting queries because at this stage every database supports AI.
Software Developer at Apptom
I think MariaDB on CentOS needs improvements in some memory-level implementations within the operating system, as I have noticed issues related to memory orientation, such as out-of-memory problems.

I find the pricing for Docker on Ubuntu is not expensive because basically, it is zero.
Founder at Asynka
Docker does not have licensing.
Cloud Operations Engineer at a tech vendor with 51-200 employees
Regarding pricing, setup cost, and licensing, in our case, it was just the open-source MariaDB, so we did not require any licenses or setup costs; we just use it directly.
Software Engineer at a outsourcing company with 201-500 employees
My experience with pricing, setup cost, and licensing has been positive since it is open source, and we did not have any issues with licensing and pricing.

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.

Performance tests have been streamlined for analysis while query tuning still needs improvement
The technical support or community support for MariaDB on CentOS is bad. There is a main problem with all the companies that sell this kind of tool and services. The first level of support is the first one you reach. When you begin to have a more difficult problem, there is no one available because sometimes you need to update the call and recall on it. This is not good because when we have some big problem on the database, we need to have a database administrator, not a person who reads instructions on the screen. It is always the same problem. My rating is two.
