Question

An ecommerce company has an order-processing application that uses Amazon API Gateway and an AWS Lambda function. The application stores data in an Amazon Aurora PostgreSQL database. During a recent sales event, a sudden surge in customer orders occurred. Some customers experienced timeouts, and the application did not process the orders of those customers. A solutions architect determined that the CPU utilization and memory utilization were high on the database because of a large number of open connections. The solutions architect needs to prevent the timeout errors while making the least possible changes to the application. Which solution will meet these requirements?

Accepted Answer

Correct answer: B. The correct answer is B. Option B: Use Amazon RDS Proxy to create a proxy for the database. Modify the Lambda function to use the RDS Proxy endpoint instead of the database endpoint. 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.
