Enterprise high availability and disaster recovery with MariaDB
Clustering, replication and automatic failover
MariaDB Platform is the first and only database (enterprise open source or proprietary) with advanced high availability features comparable to Oracle Database Enterprise Edition, and capable of supporting the development and operation of mission-critical applications.

How MariaDB Platform meets high availability requirements
In this webinar, we'll provide an in-depth overview of the enterprise high availability features in MariaDB Platform and a first look at the advanced options introduced in MariaDB Platform X3 (e.g., transaction replay).
Watch nowWhy choose MariaDB Platform when enterprise high availability is required
Clustering and replication
MariaDB Platform has multi-master clustering similar to Oracle RAC (but without the need for an expensive SAN, a single point of failure) as well as semi-synchronous replication and active standby databases like Oracle Active Data Guard or Microsoft SQL Server Availability Groups.
Automatic failover
MariaDB Platform supports automatic failover with its advanced database proxy, MariaDB MaxScale. If the primary database fails or is otherwise unavailable/unreachable, MariaDB MaxScale will promote one of the secondary databases and begin routing queries to it.
Connection and session failover
MariaDB Platform goes beyond automatic failover, with MariaDB MaxScale, its advanced database proxy, capable of failing over both database connections and active sessions to ensure mission-critical applications are not interrupted if an automatic failover occurs.
Transaction replay
MariaDB Platform, like Oracle Database with Oracle Application Continuity, can restore in-flight transactions after an automatic failover using MariaDB MaxScale, its advanced database proxy, so applications do not have to restart incomplete transactions from the beginning.
Transparent topology changes
MariaDB Platform hides all topologies changes from applications so developers do not have to write code to handle database and/or server failures. Applications are neither aware of nor interrupted by database or server failures, everything is handled by MariaDB MaxScale.
Denial of service protection
MariaDB Platform not only ensures availability in the event of a database or server failure, it can prevent denial of service attacks by blocking or stopping malicious queries intended to reduce database availability with MariaDB MaxScale, its advanced database proxy.
High availability with multi-master clustering and adaptive routing
In the example topology below, MariaDB Platform is deployed as a multi-master cluster with three database instances/nodes and uses read/write splitting to scale reads by routing writes to the primary database and load balancing reads across the secondary databases.
