Question

A company’s ecommerce website has unpredictable traffic and uses AWS Lambda functions to directly access a private Amazon RDS for PostgreSQL DB instance. The company wants to maintain predictable database performance and ensure that the Lambda invocations do not overload the database with too many connections. What should a solutions architect do to meet these requirements?

Accepted Answer

Correct answer: B. The correct answer is B. Option B: Point the client driver at an RDS proxy endpoint. Deploy the Lambda functions inside a VPC. AWS Lambda runs code without provisioning servers and scales automatically, which minimizes operational overhead. Amazon RDS Proxy pools and shares database connections to improve scalability and resilience. Amazon RDS is a managed relational database that handles patching, backups and failover.
