SAP-C02 Design for New Solutions Practice Question
A company wants to decouple a microservices architecture where one service (producer) sends events to another service (consumer). The producer can generate bursts of events, and the consumer processes them in batches. The solution must be serverless and handle potential consumer failures without losing events. Which AWS service should be used as the message broker?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Amazon SQS
Amazon SQS is a serverless message queue that can buffer bursts and retain messages until the consumer processes them, with dead-letter queues for failures. Option A is wrong because Amazon SNS pushes messages to subscribers and does not support polling or batch processing. Option B is wrong because Kinesis Data Streams is for real-time streaming, not simple decoupling with batch processing. Option C is wrong because EventBridge is for event routing, not a message queue.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Amazon SNS
Why it's wrong here
SNS is a pub/sub messaging service that pushes messages to subscribers; it does not support polling or batch consumption.
- ✗
Amazon Kinesis Data Streams
Why it's wrong here
Kinesis is for real-time streaming of data, not for simple decoupling with batch processing.
- ✗
Amazon EventBridge
Why it's wrong here
EventBridge is an event bus for routing events between services; it does not provide a message queue for decoupling.
- ✓
Amazon SQS
Why this is correct
SQS provides a durable, serverless queue that decouples producers and consumers, supports batch processing, and can retain messages on failure.
