What is the purpose of an event-driven architecture in microservices?
A) To enable services to communicate asynchronously using events
B) To ensure synchronous communication between services
C) To manage service configurations
D) To log events generated by microservices
Answer:
A) To enable services to communicate asynchronously using events
Explanation:
An event-driven architecture in microservices allows services to communicate asynchronously using events. In this architecture, services produce events when certain actions or changes occur, and other services can consume these events to trigger their own actions or workflows.
This decouples services, allowing them to operate independently and react to events as they occur rather than relying on direct, synchronous communication. Event-driven architectures are particularly useful in scenarios where real-time data processing, responsiveness, and scalability are critical.
