Microservices - Event-Driven Architecture

You are designing a microservices system where a new user registration must update internal user metrics, notify other services, and send a welcome email. Which event types should you use for each action?

AIntegration event for metrics update, domain event for other services, notification event for email

BDomain event for metrics update, integration event for other services, notification event for email

CNotification event for metrics update, domain event for other services, integration event for email

DDomain event for email, integration event for metrics update, notification event for other services

Step-by-Step Solution

Solution:

Step 3: Assign notification event
Use notification events to send emails or user-facing messages.
Final Answer:
Domain event for metrics update, integration event for other services, notification event for email -> Option B
