Galera Cluster

Galera Cluster is a technology that allows multiple database servers to work together as a single, synchronized system. Think of it as several identical copies of a database that update each other automatically, ensuring data is consistent across all servers. This setup provides high availability—if one server fails, others continue to operate without interruption—making systems more reliable. It also improves performance by distributing the workload. Overall, Galera Cluster helps businesses maintain continuous, fast, and reliable access to data, even in the face of hardware issues or high demand.
