First things first, Event-driven architecture. EDA and serverless functions are two powerful software patterns and concepts that have become popular in recent years with the rise of cloud-native computing. While one is more of an architecture pattern and the other a deployment or implementation detail, when combined, they provide a scalable and efficient solution for modern applications.
What Is Event-Driven Architecture
EDA is a software architecture pattern that utilizes events to decouple various components of an application. In this context, an event is defined as a change in state. For example, for an e-commerce application, an event could be a customer clicking on a listing, adding that item to their shopping cart, or submitting their credit card information to buy. Events also encompass non-user-initiated state changes, such as scheduled jobs or notifications from a monitoring system.
