Key takeaways

  • Continuous Availability: MariaDB Enterprise Cluster combines synchronous replication with intelligent traffic routing to ensure your mission-critical applications stay online without manual intervention during a failover.
  • Guaranteed Data Integrity: By synchronizing transactions across all nodes instantly, the platform eliminates “replica lag” and protects your business against data loss or discrepancies.
  • Fully Managed Growth: The new PowerPlus tier handles the heavy lifting of cluster provisioning, automated backups, and health monitoring so your team can focus on building applications rather than managing infrastructure.

The modern enterprise doesn’t just run on data, it survives on the absolute certainty of that data. As applications become more global, more distributed and increasingly AI-driven, the expectations placed on cloud databases (DBaaS) have fundamentally changed. Enterprises need more than backups and replicas. They need continuous availability, consistent performance and intelligent traffic management, all built into the core. 

Today, we are taking a massive leap forward in that journey. We are thrilled to introduce MariaDB Enterprise Cluster (powered by Galera) on MariaDB Cloud. By combining the battle-tested resilience of Galera Cluster with the intelligent traffic management of MariaDB MaxScale, we are delivering a fully managed, enterprise-grade solution for your mission-critical workloads.

The Heart of Resilience: Galera’s Synchronous Power

Traditional high availability often struggles with “eventual consistency” and replica lag. MariaDB Enterprise Cluster eliminates these issues through synchronous replication.

When you commit a transaction, it is synchronized across the cluster nodes, ensuring:

  • Zero Data Loss: Protection against data discrepancies during failover.
  • Cluster-Wide Consistency: Every node is always in sync, eliminating the lag typical of asynchronous systems.
  • Automatic Membership: The cluster manages its own health, automatically handling node arrivals and departures.

The Brain of the Operation: HA Scale Powered by MaxScale

While Enterprise Cluster provides the muscle for data integrity, MariaDB Cloud’s HA Scale serves as the intelligent brain fronting the cluster. HA Scale combines the advanced traffic routing of MaxScale with autoscaling capabilities to ensure your cluster dynamically adapts to changing query load and patterns.

By integrating HA Scale into our Enterprise Cluster solution, you gain a foundation built for growth and benefit from:

  • Transparent Failover: If a node becomes unavailable, Enterprise Cluster will select a new primary. MaxScale detects this shift and reroutes traffic instantly. Your application keeps running without needing connection string changes or manual intervention.
  • Intelligent Traffic Routing: MaxScale automatically directs writes to the primary node while balancing read queries across all available replicas to optimize performance.
  • Advanced Security and Management: From connection pooling to query filtering, MaxScale shields your database and ensures efficient resource utilization.

From Precision to Parallelism

To ensure the highest levels of stability and performance for our cloud customers, this Technical Preview release of Enterprise Cluster in MariaDB Cloud focuses on a robust single-writer architecture. This will ensure:

  • Strong transactional consistency
  • Predictable performance characteristics
  • A simpler path for customers migrating from primary-replica architecture
  • A reliable path for transitioning to synchronous clustering in the Cloud

Multi-writer capability is planned for a future release, unlocking advanced active-active write scaling for global workloads. We are building toward that capability carefully prioritizing reliability and production readiness at every stage.

Focus on Building, Not Orchestrating

MariaDB Cloud wraps the capabilities of Enterprise Cluster and MaxScale into a fully-managed experience delivering:

  • Automated cluster provisioning
  • Intelligent load balancing and failover
  • Health monitoring and recovery
  • Automated backups and recovery

We do all the heavy lifting, so your team can focus on what actually matters: building world-class applications. Whether you are powering financial services, global SaaS platforms, or the next generation of AI-native apps, MariaDB Enterprise Cluster is built for your production environment.

New PowerPlus Tier

Enterprise Cluster on MariaDB Cloud will be available exclusively on our new PowerPlus tier. This tier extends the high availability of the Power tier to offer the highest standards of resilience and security isolation for mission critical workloads.
