Introducing event-driven architecture

Event-driven architecture is a paradigm that relies on events to initiate and facilitate communication among loosely coupled services. It is a prevalent approach in applications developed using microservices.

Because of its asynchronous characteristic, event-driven architecture decouples event production from event consumption and robustly handles asynchronous data flows.

An event is a significant change in state or an occurrence that necessitates awareness and response from other parts of the system.

Asynchronous communication

In the context of event-driven architecture, asynchronous communication refers to a method of interaction where microservices exchange information without requiring both parties to be available and active simultaneously. Asynchronous communication can decouple services and allow them to communicate by sending messages that can be processed later rather than waiting for an immediate response, as in synchronous...
