A company requires a scalable and decoupled solution for an application that handles variable, high-volume message ingestion, reaching up to 100,000 messages per second. Which AWS service configuration is appropriate for this scenario?
Explanation:
The correct answer is D. Publishing messages to an Amazon Simple Notification Service (SNS) topic and using multiple Amazon Simple Queue Service (SQS) subscriptions is a highly scalable and decoupled architecture. SNS provides a robust message delivery mechanism, and SQS allows for scaling of the message processing by distributing the messages across multiple queues. This setup ensures that the messages are effectively managed even when the ingestion rate spikes to 100,000 messages per second.
