Amazon RDS Proxy is a fully managed database proxy that makes applications more scalable, more resilient to database failures, and more secure. RDS Proxy sits between your application and your relational database to pool and share established database connections, improving database efficiency and application scalability. RDS Proxy also reduces the load on the database by handling connection management and query retries for transient errors. By deploying RDS Proxy between your serverless application and Amazon RDS, you can avoid opening and closing connections to the database frequently, which can cause errors or run out of connections. This solution will also reduceoperational costs and improve availability of your application. References:https://aws.amazon.com/rds/proxy/
