A legacy application frequently opens and closes connections while it is migrated to RDS.
Reduce database connection load without changing the application code.
Which service is most appropriate?
Use Amazon RDS Proxy to manage and reuse connections between the legacy application and the RDS database.
Detailed explanation
Per-request clusters increase both connection load and operational overhead.

This does not preserve the application's relational database interface and is not a connection-management solution.

Foundation review
Compatibility layer
A proxy can improve connection behavior while preserving the application's database endpoint and protocol.
Operational trade-off
The proxy reduces connection churn but does not replace database sizing, query tuning, or access controls.
