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

Event-driven microservice architecture allows services to communicate by publishing and subscribing to events, enabling asynchronous communication. This approach improves scalability, reliability, and allows services to evolve independently. It supports real-time processing and handles high volume events efficiently. Each service is responsible for a specific business capability, facilitating easier maintenance and parallel development. Overall, this architecture promotes modular, scalable, and resilient systems.

What is a key advantage of asynchronous communication in event-driven microservice architecture?

• It requires services to wait for responses.

• It allows services to operate independently.

• It decreases system reliability.

• It complicates service communication.

How does decoupled communication benefit event-driven microservice architecture?

• It limits the scalability of the system.

• It requires direct API calls between services.

• It forces services to evolve together.

• It allows services to evolve independently.

What is a benefit of real-time processing in event-driven architectures?

• Events are handled as soon as they occur.

• It requires synchronous communication.

• It is unsuitable for high-volume events.

• Events are processed with significant delay.

In event-driven microservice architecture, what is each service responsible for?

• Directly calling other services' APIs.

• Managing the entire system's database.

• Handling all system functions.

• A specific function or business capability.

What is a key feature of event-driven microservice architecture in terms of system design?

• It complicates scalability.

• It makes systems less modular.

• It discourages parallel development.

• It supports building modular and resilient systems.
