This MySQL Galera Cluster Administration training is designed to help participants deploy, manage, and operate highly available MySQL clusters using Galera replication. The course covers Galera architecture, synchronous replication, cluster deployment, quorum management, backup strategies, performance tuning, and operational best practices. Participants will gain hands-on experience to build resilient MySQL Galera clusters for mission-critical, high-availability database environments.

• Understand the architecture, clustering capabilities, and high-availability features of MySQL with Galera Cluster for enterprise database  management.
• Set up and configure the MySQL 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 MySQL Galera best practices.
