This white paper explains how to evaluate a high-availability (HA) solution using an airport system failure as a case study, demonstrating how incomplete replication can lead to service disruption, outdated data, and operational crises. It highlights the essential capabilities of an effective HA solution, including synchronous replication, automatic failover, centralized monitoring, rapid recovery, backup server resynchronization without downtime, split-brain protection, disaster recovery, and user-friendly administration. The paper emphasizes that data replication alone is not sufficient for true high availability and recommends software clustering solutions that minimize downtime, prevent data loss, simplify deployment, and ensure continuous operation of mission-critical applications acr
