Question

A company wants to enhance its ecommerce order-processing application that is deployed on AWS. The application must process each order exactly once without affecting the customer experience during unpredictable traffic surges. Which solution will meet these requirements?

Accepted Answer

Correct answer: A. The correct answer is A. Option A: Create an Amazon Simple Queue Service (Amazon SQS) FIFO queue. Put all the orders in the SQS queue. Configure an AWS Lambda function as the target to process the orders. AWS Lambda runs code without provisioning servers and scales automatically, which minimizes operational overhead. Amazon SQS is a fully managed message queue that decouples components and absorbs traffic spikes. AWS Config tracks resource configuration changes and evaluates compliance.
