Serverless Services in AWS

Event Driven Architecture

An event-driven architecture uses events to initiate actions and communication between decoupled services.

Wht is an event?

An event is a change in state, a user request, or an update, like an item being placed in a shopping cart in an e-commerce website. When an event occurs, the information is published for other services to consume it. In event-driven architectures, events are the primary mechanism for sharing information across services.
