# High Availability with MariaDB

## High Availability for Mission-critical Applications

[MariaDB Enterprise Platform](https://staging-mdb.com/products/enterprise/) offers robust high availability and disaster recovery solutions comparable to proprietary databases like Oracle, ensuring business continuity and data protection for your mission-critical applications.

  
  
## Advanced Clustering and Replication

MariaDB provides multimaster node clustering, similar to Oracle RAC but without the need for an expensive SAN, as well as semi-synchronous replication and active standby databases, comparable to Oracle Active Data Guard and Microsoft SQL Server availability groups.

  
  
### Seamless Failover and Recovery

#### Automatic failover

[MariaDB MaxScale](https://staging-mdb.com/products/maxscale/), our advanced database proxy, automatically promotes a secondary database and reroutes queries if the primary database fails.

#### Connection and session failover

MaxScale goes beyond basic failover by seamlessly transferring active connections and sessions to the new primary database, preventing application interruptions.

#### Transaction replay

Like Oracle Application Continuity, MariaDB can restore in-flight transactions after a failover, ensuring data integrity and preventing data loss.

### Simplified Application Development

#### Transparent topology changes

Shields applications from underlying topology changes, so developers don’t need to write complex code to handle database or server failures.

#### Cyberattack protection

Prevent denial of service (DoS) and distributed denial of service (DDoS) attacks by blocking or stopping malicious queries, ensuring continuous availability.

#### With MariaDB’s comprehensive high availability and disaster recovery features, you can achieve enterprise-grade reliability without the complexity and cost of proprietary solutions.

## High Availability and Scalability with Multimaster Clustering

The example topology below demonstrates how MariaDB delivers high availability and read scalability through multimaster clustering and adaptive routing. Three database instances form a cluster, with read/write splitting directing write operations to the primary node while distributing read operations across all nodes for optimal load balancing.
