Microservices - Event-Driven Architecture
Why is it important to distinguish between domain, integration, and notification events in microservices design?
ABecause all events must be handled synchronously
BBecause notification events are always stored in the database
CBecause each event type has different scopes, consumers, and reliability requirements
DBecause domain events are only used for logging
Step-by-Step Solution

    Domain events affect internal service state, integration events cross service boundaries, notification events inform users or external systems.
  2. Step 2: Recognize different requirements

    Each event type has different consumers and reliability needs, affecting design choices.
  3. Final Answer:

    Because each event type has different scopes, consumers, and reliability requirements -> Option C
  4. Quick Check:

    Event types differ by scope and use [OK]
Quick Trick: Event types differ in scope and consumers [OK]
Common Mistakes:
MISTAKES
  • Assuming all events are synchronous
