SAP-C02 Practice Question: Design Solutions for Organizational Complexity
Which THREE design patterns are recommended for decoupling components in a microservices architecture on AWS?
⚠ Common exam trap
Watch out — candidates often confuse network connectivity solutions (Direct Connect) or load balancing (ELB) with true decoupling patterns, but decoupling in microservices requires asynchronous, event-driven or message-based integration, not synchronous request/response or network links.

Correct answer & explanation
✓
Use Amazon EventBridge for event-driven integration.
Amazon EventBridge provides a fully managed event bus that decouples microservices by enabling event-driven communication. Services publish events to EventBridge, which then routes them to appropriate consumers based on rules, eliminating direct dependencies between producers and consumers.

- ✓
Use Amazon SNS topics for pub/sub messaging.
Why this is correct
SNS enables one-to-many decoupling.
- ✓
Use Amazon SQS queues between services.
