MySQL is one of the largest open source database communities. MariaDB is a fork from MySQL and is compatible with prior versions of MySQL.
MySQL / MariaDB is an open source database. MariaDB is backwards compatible with all versions of MySQL and is a more improved version of MySQL with extra security and features. The two platforms are often used together so that users can benefit from both of their features.
Vertically scale-out through the usage of parallel query, read replication, and multi-master clustering, all while maintaining continuous availability with the ability to hide failures from applications using multi-write clusters and zero-interruption failover features.
Horizontal scaling adds new nodes which are connected to the cluster with all the required adjustments applied on automatically.
Each cluster is supplemented with two ProxySQL nodes along with automatic splitting of read/write requests for efficient load balancing.
Any database nodes that become temporarily unavailable or have high latency are automatically excluded from the cluster and re-added once the connection is restored to normal.
By using partitioning, performance is improved and provides faster management of large databases.
MySQL / MariaDB has a range of documentation to help you setup your system and learn how to troubleshoot.
Zeus Cloud also offers support for MySQL / MariaDB, if you need assistance please open up a support ticket.
