Tungsten Clustering vs. Microsoft Azure

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 Clustering

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

Microsoft Azure

Azure Database for MySQL comes in two varieties: “Single Server” with no failover replica, or “Flexible Server” with a failover replica. Flexible Server was just released as GA in November 2021. Read replicas can be used on either version and a 3rd-party proxy would be needed to fully utilize the read replicas without application changes.

Connectivity Direct (might benefit from 3rd party solution)

Orchestration Limited

Replication Synchronous for failover replica, asynchronous for local read replicas, N/A for global needs
