Tungsten Cluster vs. Galera Cluster

MySQL and MariaDB Clustering Solutions Comparison

Learn why Tungsten Clustering is a better (complete, proven) and more cost-effective (software, 24/7 support and consulting all included) MySQL High Availability (HA), Disaster Recovery (DR) and Geographically-Distributed (Geo-Scale) solution compared to Amazon AWS Aurora for MySQL.

For any MySQL clustering to be a complete high-availability and disaster recovery solution, it requires three core components working in sync: connectivity (proxy), management (orchestration) and replication (local/global).

Tungsten Cluster

Tungsten Clustering includes three highly integrated and fully tested components Tungsten Proxy, Tungsten Manager and Tungsten Replicator working together to provide both local (individual clusters) and global (multiple clusters working together) data service for continuous 24/7 MySQL operations.

Connectivity Complete and Integrated (Tungsten Proxy)

Orchestration Integrated Business Rules (Tungsten Manager)

Replication Advanced Local and Global (Tungsten Replicator)

 Connectivity
 Orchestration
 Replication

Galera Cluster

Galera Cluster is a decent solution for local MySQL HA needs, especially when dealing with smaller sized transactions. As workloads increase, transactions become larger, or if geo distribution is needed, Galera Cluster becomes less attractive due to significant performance overhead. Also a 3rd-party proxy or load balancer would be needed for maximum performance and availability benefits.

Connectivity Direct (benefits from 3rd party proxy or load balancer)

Orchestration Limited

Replication Sync replication for local needs, N/A for multi-site/global needs
