Spring Boot - Messaging

Why is event-driven architecture considered more scalable in Spring Boot applications?

ABecause it forces all components to run on the same thread

BBecause it decouples components allowing independent scaling and asynchronous processing

CBecause it requires all events to be processed in a single transaction

DBecause it eliminates the need for service layers

Step-by-Step Solution

Solution:

Step 1: Understand scalability in event-driven systems
Decoupling allows components to scale independently and handle events asynchronously.
Step 2: Contrast with incorrect options
Running on same thread or single transaction limits scalability; service layers are still needed.
Final Answer:
Because it decouples components allowing independent scaling and asynchronous processing -> Option B
Quick Check:
Decoupling + async = better scalability [OK]

Quick Trick: Decoupling and async processing boost scalability [OK]
