AWS Certified Solutions Architect Associate SAA-C03 Practice Question
Which service feature should you use to manage a large number of concurrent database connections that often experience unpredictable spikes in connection requests, while ensuring minimal changes to the existing applications?
Amazon RDS Proxy is designed to handle a large volume of concurrent database connections and smooth out spikes in connection requests to RDS databases. It mitigates database overload by absorbing the connections to create a connection pool and by reducing database failovers through intelligent load balancing. Using RDS Proxy decreases the need to refactor the applications that are not designed to manage such spikes, which distinguishes it from the other answer options that do not offer the same degree of functionality for this specific requirement.
