Microservices architectures are designed to be highly

modular and flexible, that can be scaled and managed

separately and use of APIs to communicate between services.

▪ Event-driven architecture, microservices can communicate

by publishing and subscribing to events, than directly calling

each other's APIs.

▪ Event-driven microservice architecture is means

communicating with microservices via event messages and

we can do asynchronous behavior and loosely coupled.

▪ Instead of sending request when data needed, services

consume them via events.

▪ Huge Innovations on the Event-Driven Microservices

Architectures;

▪ Real-time messaging platforms, stream-processing, event

hubs, real-time processing, batch processing, data

intelligence.
