Many have suggested using DDD to help define the functional scope of microservices. But how to apply this idea in practice is not clear to everyone. This talk will cover basic DDD concepts, and we'll discuss why and how DDD can help to create microservices with better autonomy, scalability, and reliability. Using examples, we'll navigate from a domain model to the design of both synchronous (REST-based) and asynchronous (reactive) microservices.

Target Audience: Architects, Developers, PM's, QA
Prerequisites: Understanding of Microservices and DDD is useful

Extended Abstract:
Many have suggested that DDD modeling techniques can help define the functional scope of microservices. But how to apply this idea *in practice* is not clear to everyone. DDD is NOT an approach to microservice design. However, DDD can help with some aspects of microservice design. DDD has had a resurgence with the advent of Microservices, specifically as it can help you design the right-sized microservices modeled around the domain.

This talk will examine how to take the results of domain modeling (specifically Domain-Driven Design) and map them to a microservices implementation for systems with better availability, scalability, reliability, and modifiability. This will include examples for the design of both synchronous (REST-based) and asynchronous (reactive) microservices. I will also explore various microservice design scenarios around DDD concepts such as aggregates (with entities and value objects), bounded contexts, domain events, anti-corruption layer, and various strategies for Bounded Context interactions.
