High Availability (HA) is critical for ensuring the continuous operation and performance of modern applications. MySQL, a widely used relational database management system, provides replication features to achieve data redundancy and scalability. However, achieving optimal HA requires more than just replication; it necessitates sophisticated tools for load balancing and failover management. In this detailed article, we’ll explore how to set up a robust HA environment using ProxySQL for load balancing and Orchestrator for failover and topology management. This guide covers advanced configuration details, performance tuning, and integration strategies for a seamless HA solution.
