To reduce RDS failover time to under 20 seconds, combining Amazon Aurora MySQL with Aurora Replicas and RDS Proxy is the most effective solution. Aurora (D) supports faster, automatic failover than RDS MySQL. Aurora Replicas (E) act as pre-provisioned failover targets, minimizing downtime. RDS Proxy (C) handles persistent DB connections, auto-retries, and insulates the application from the failover event. This trio reduces both failover execution time and application recovery time, ensuring high availability with minimal interruption.
