Question

An ecommerce website uses an AWS Lambda function and an Amazon RDS for MySQL database for an order fulfillment service. The service needs to return order confirmation immediately. During a marketing campaign that caused an increase in the number of orders, the website's operations team noticed errors for “too many connections” from Amazon RDS. However, the RDS DB cluster metrics are healthy. CPU and memory capacity are still available. What should a developer do to resolve the errors?

Accepted Answer

Correct answer: B. The correct answer is B. Option B: Initialize the database connection outside the handler function. Use RDS Proxy instead of connecting directly to the DB cluster. 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.
