Modeling Microservices with DDD

Abstract

Many have suggested using Domain-Driven Design (DDD) to help define the functional scope of microservices. But how to apply this idea in practice is not clear to everyone. DDD is a domain modeling technique created in the early 2000s. Microservices is an architecture style that became popular in 2015 as means to break software solutions into a set of independently deployed services. In this full-day tutorial we’ll cover basic DDD concepts and discuss why and how DDD can help to create microservices with better availability, scalability, reliability, and modifiability. Using examples, we’ll navigate from a domain model created using DDD to the design of both synchronous (REST-based) and asynchronous (reactive) microservices. We’ll explore five different microservice design scenarios around DDD aggregates, bounded contexts (BC), domain events and other strategies for inter-BC interaction.
