# MariaDB

## Description

MariaDB is an open-source database management system created by the original developers of MySQL. MariaDB uses tables to store data in an organized way, and it is possible to interact with the database using SQL queries.

It supports concepts such as primary keys, indexes and relationships between tables. MariaDB is widely used for data storage and management in a variety of applications, from websites to enterprise systems. It is a popular choice due to its reliability, performance and open-source nature.

## Platform as a Service

MariaDB is deployed on-premise in **cegedim.cloud'**&#x73; data centers. The long term support (LTS) can be deployed in self-service using ITCare

The same level of service as the Compute offer is guaranteed : deployment of instances, maintenance in operational condition, flexibility, security and monitoring are thus ensured by our experts.

Two topologies are available in self-service :

* Standalone (replica can be added on request)
* Galera cluster (3 nodes)

Galera cluster is production ready with at least 3 nodes spread over all Availability Zones of a target Area.

Sizing can be configured according to your needs.
