Consider this scenario: Service A sends an event to a message broker, and Service B listens and processes it asynchronously. What is the main advantage of this design?

Microservices - Event-Driven Architecture

AService B can process events at its own pace without blocking Service A.

BService B must respond immediately to Service A's request.

CService A and B share the same database for faster communication.

DService A waits for Service B to finish processing before continuing.

Step-by-Step Solution

Solution:

Step 1: Analyze asynchronous event processing
Service A sends an event and does not wait; Service B processes independently.
Step 2: Identify the advantage
This allows Service B to handle events at its own speed without blocking Service A, improving scalability and decoupling.
Final Answer:
Service B can process events at its own pace without blocking Service A. -> Option A
Quick Check:
Asynchronous event-driven = decoupled processing [OK]

Quick Trick: Async events let receivers work independently [OK]

Common Mistakes:

MISTAKES

Assuming sender waits for receiver
Confusing shared database with event broker
Expecting immediate response in event-driven
