1. Use Case & Need

This section details the driving need for the high-availability database cluster project. Mission-critical systems required continuous database availability. Traditional single-node setups led to unacceptable downtime. The design was initiated to:

• Ensure uninterrupted database service through redundancy.
• Provide automated failover in the event of node failure.
• Maintain data integrity with real-time replication across nodes.
• Address both performance and security requirements for a distributed environment.

By addressing these needs, the project aims to minimize downtime and ensure the reliability of critical applications.
