Description

Introduction
This training explores how Domain-Driven Design (DDD) integrates with event-driven architecture to build reactive, scalable, and loosely coupled systems. Participants will learn to design domain events, implement event flows, and apply patterns that enable real-time and asynchronous microservices communication.

Prerequisites

• Basic understanding of DDD concepts

• Familiarity with microservices and REST

• Knowledge of messaging systems such as Kafka, RabbitMQ, or Azure Service Bus
