This MariaDB Galera Cluster Administration training is designed to help participants deploy, manage, and troubleshoot highly available MariaDB clusters using Galera replication. The course covers Galera architecture, cluster setup, synchronous replication, quorum and flow control, backup strategies, performance tuning, and operational best practices. Participants will gain hands-on experience to build resilient, multi-node MariaDB Galera clusters for mission-critical database environments.

• Understand the architecture, clustering capabilities, and high-availability features of MariaDB with Galera Cluster for enterprise  database management.
• Set up and configure the MariaDB and Galera Cluster environment, nodes, replication settings, and cluster components for high-  availability database operations.
• Design cluster topologies, node configurations, replication workflows, and failover strategies using Galera administration approaches.
• Implement cluster deployment, synchronization, backup management, load balancing, and disaster recovery workflows effectively.
• Debug, test, and optimize cluster performance, replication consistency, and node reliability for scalability and availability.
• Build secure, fault-tolerant, and production-ready clustered database solutions using MariaDB Galera best practices.
