I use MariaDB on CentOS as a database for other applications, and in our field, we need absolute availability. MariaDB on CentOS offers, with an additional product called Galera, a very dependable solution, and I am very enthusiastic about it.

At the moment, I am setting up a cluster of MariaDB on CentOS.

The Galera Cluster feature has helped me with high availability because it is stable, requiring at least three servers to have a stable cluster. If one member of the cluster stops for any reason, the service continues working, and as you restart the server, it synchronizes everything with the other members. It is very well designed; while it is a complex feature and is documented, every improvement in this area would be helpful, and this is a suggestion for the Galera and MariaDB on CentOS developers.

MariaDB on CentOS is a very good SQL database that is open source, meaning no license cost for users. There are even commercial editions that offer support, but basically, you do not need to pay any license. It is very dependable and very clear.

You can always improve a product, and the area that is very sensitive in MariaDB on CentOS is the release and the backward compatibility.

I have worked with MariaDB on CentOS for five years; however, MariaDB on CentOS is not my central focus.

I rate the reliability and stability level of MariaDB on CentOS as very high; it is among the best databases that I have ever seen. Compared to another database, PostgreSQL, for example, I find PostgreSQL is not a bad database, but as far as clustering is concerned, it is a bit confusing, and the documentation is not as good. I prefer to work with MariaDB on CentOS and even for Microsoft SQL, their documentation and experience with clustering is not as good as here. Among these three databases, I would give a 10 to MariaDB on CentOS, a 9 for PostgreSQL, and a 9 for MS SQL.

I rate how scalable MariaDB on CentOS is as lacking experience in this area; I know there is an issue, but I have never performed real tests. For example, several years ago, a customer wanted scalability tested on another technology, LDAP, with two million objects, and that was acceptable. If somebody comes to me requesting to test with 60 million objects, I will do that test, but it is demanding and I am not going to do this just for the sake of it.

I have never gotten in touch with technical support for MariaDB on CentOS because I was able to solve the problem autonomously. I did not need that, but they send me from time to time mailings or making offers, which is perfectly appropriate.

Before using MariaDB on CentOS, I used both MS SQL and PostgreSQL; if the customer absolutely wants MS SQL, we make the installation with MS SQL, but if the customer asks me what the preferred solution is, I am going to suggest MariaDB on CentOS.

My experience with the initial setup of MariaDB on CentOS is that it is complex, but the documentation is better than PostgreSQL. It is highly standard SQL, so it is not really a difference; I am more of an infrastructure person than a database person. I am interested in stability, not the language, and I find the good standard SQL from my point of view is acceptable.

I am working with many technologies, including a quite old and stable technology named LDAP, Lightweight Directory Access Protocol, and some relatively new technologies for us, such as a Linux database called MariaDB on CentOS. Every day I encounter new technologies.

I have not tested MariaDB on CentOS with a very high volume, but I test technologies and if I find a good technology, I offer that to the customer, and the customer can ask me to test this with X millions of objects. Basically, I stick with the feature that I need most, which is reliability and cluster capability.

Overall, for MariaDB on CentOS, I am certain I can vote 10. CentOS is very good, even a 10, but I must inform you that CentOS is moving away and transitioning to followers of CentOS called Rocky Linux or other names. At the moment, I was forced to migrate from CentOS to Rocky Linux. A very interesting question for everybody would be a comparison between the open source Linux distributions, such as Fedora, SUSE, Rocky Linux, and Ubuntu, which is in high demand. I would rate my overall experience with MariaDB on CentOS as a 10.

MariaDB on CentOS is used in a hybrid cloud and public cloud environment. It has been deployed in AWS and DigitalOcean, installed separately rather than as a managed service.

MariaDB on CentOS is almost identical to MySQL, and the experience is very similar. However, I found that MariaDB on CentOS performs better than MySQL in production. If you use MySQL, I would recommend moving to MariaDB on CentOS as it will give you better performance in production. The switch is not a big deal, but MariaDB on CentOS performs significantly better than MySQL in production environments.

I did not purchase MariaDB on CentOS on CentOS through the AWS Marketplace; I installed it separately.

I have been working for almost six months with my current company, and I have worked as a software engineer since 2007.

I do not have any specific relationship with MariaDB on CentOS other than being a customer.

I have used MySQL, MariaDB on CentOS, and PostgreSQL. When comparing MariaDB on CentOS with MySQL, I found that MariaDB on CentOS performs better than MySQL. I do not think any other database performs better than MariaDB on CentOS when compared with MySQL, which is why I give it a 10.

I have never used MariaDB on CentOS on CentOS, but I have used MariaDB on CentOS on other operating systems. I used MariaDB on CentOS mainly on Ubuntu, not on CentOS.

I believe I have covered every important aspect to discuss, and I do not have anything else to add. I was offered a gift card. My overall review rating for MariaDB on CentOS is 10.
