Design Microservices Architecture with Patterns and Principles - Design Event-Driven Microservices Architecture

What is a key feature of event-driven microservice architectures?

• Direct API calls between services

• Asynchronous decoupled communication

• Centralized data storage

• Synchronous communication

Which component is central to enabling communication in an event-driven microservice architecture?

• API gateway

• Event hub

• Database

• Load balancer

In the context of event-driven architectures, what is the role of an event hub?

• To act as a central hub for data ingestion and distribution

• To enable synchronous communication

• To replace all microservices

• To store all microservice data

How do microservices communicate in a fully decoupled architecture?

• Using a shared file system

• Through direct API calls

• Asynchronously through an event hub

• Via a centralized database

What is one benefit of using event-driven microservice architectures in e-commerce applications?

• Reduced need for data processing

• Enhanced scalability and flexibility

• Simplified synchronous communication

• Increased dependency between services
