Description

Introduction
This training explores how Domain-Driven Design (DDD) principles can be applied to microservices architecture to build systems that are scalable, maintainable, and aligned with business goals. Participants will learn to model domains, define bounded contexts, and implement effective communication between microservices.

Prerequisites

• Basic understanding of software architecture and object-oriented programming

• Familiarity with microservices concepts and RESTful APIs

• Experience with a programming language like Java, C#, or Python
