Domain-Driven Design and microservices Hands-on workshop

Abstract

This Hands-on workshop would help with learning Domain-Driven Design fundamentals and how to apply them for better microservices architecture. We will also cover how to decide on boundaries of microservices and how/when to split microservices using Domain-Driven Design. Why Domain-Driven Design? DDD is very useful for designing scalable systems and platforms and the basis for designing better microservices architecture. On the data side, DDD is useful for building distributed data architectures including data mesh. DDD also helps with organizing a large team. This one-day workshop will help you learn how to use domain-driven design to split domain and to design better microservice-style architectures. You’ll learn the DDD vocabulary and strategic patterns. Throughout the workshop, you’ll complete exercises in which the name of the domain-driven design concept is initially hidden until you code the problem statement, and then it will be revealed. Using simple coding use cases, you’ll learn DDD from the bottom-up to understand how current and existing code bases can be refactored to use DDD. You will learn - The relationship between DDD and microservices Tactical and strategic DDD patterns Domain model as the primary and most important layer in three-tier/three-layer and hexagonal architecture Domain events, which are the basis for event-driven architecture And you will be able to - Come up with a microservice using the DDD aggregate concept Design and evolve better boundaries for microservices using DDD Understand the domain layer and its importance in the overall success of a project Apply DDD tactical patterns to existing code bases Topics Covered : The what/why/when of domain-driven design; domain-driven design and friends What is a domain layer in the context of 3-tier/3-layer and hexagonal architecture?
