Why should we go for DDD in microservices?
DDD provides an essential technique for managing the interplay between each of the parts, be it a ubiquitous language, bounded contexts, schemas, and anti-corruption layers. As we have seen, events and messaging provide key ingredients for making these systems work well in practice.
What is DDD oriented microservice?
Domain-driven design (DDD) advocates modeling based on the reality of business as relevant to your use cases. In the context of building applications, DDD talks about problems as domains. In addition, DDD approaches should be applied only if you are implementing complex microservices with significant business rules.
How does a domain model apply to a microservice?
A domain model with specific domain entities applies within a concrete BC or microservice. A BC delimits the applicability of a domain model and gives developer team members a clear and shared understanding of what must be cohesive and what can be developed independently. These are the same goals for microservices.
Who are the same entities in a microservice?
The same entity appears as “Users”, “Buyers”, “Payers”, and “Customers” depending on the bounded context. You’ve identified several BCs that could be implemented as microservices, based on domains that domain experts defined for you.
Which is the right approach to building microservices?
Using the right approach to building microservices it’s more about the software’s architectural design, providing a structure of practices to take design decisions that help in software projects that have complicated domains. It focuses on the area of a specific business to gain a better understanding of what the domain is all about.
Are there downsides to service oriented microservice architecture?
Recently there has been substantial discussion around the downsides of service oriented architectures and microservice architectures in particular.
