AWS Certified Solutions Architect Associate SAA-C03 Practice Question
How does using Amazon RDS Proxy help improve the performance and scalability of an Amazon RDS database?
It maintains a pool of established database connections and multiplexes application requests, reducing the number of idle connections that reach the database.
It compresses all SQL traffic between the application and the database, cutting network latency by half.
It automatically creates and manages read replicas to offload read traffic without changing application code.
It periodically restarts the database instance to clear idle sessions and reclaim resources.
Amazon RDS Proxy sits between your application and the database, keeps a pool of established connections, and multiplexes application requests onto a smaller set of database connections. This reduces the CPU and memory overhead on the database that would otherwise be spent opening, maintaining, and closing large numbers of idle or transient connections, allowing the database to devote more resources to serving queries.
