Using RDS Proxy with Amazon RDS Multi-AZ DB instance deployment to improve planned failover time
Database Blog
This article discusses how Amazon RDS Proxy can improve planned failover times for Multi-AZ database deployments across MySQL, MariaDB, and PostgreSQL.
- RDS Proxy eliminates the 35-second DNS propagation delay during failovers
- Optimizations were made to reduce downtime during different maintenance operations
- Benchmarking showed significant improvements in failover performance:
- Up to 4.9X reduction in instance class modification downtime
- Up to 4.8X reduction in OS upgrade downtime
- Up to 3X reduction in forced failover downtime
The improvements are automatically available for RDS MySQL, MariaDB, and PostgreSQL instances, requiring no additional configuration from users.
