Domain And Subdomain In Microservices
Subdomain could also refer to business domain.
Domain and subdomain in microservices. In short instead of having to type each website s ip into our browsers domain names give websites their own good looking name that can be easily memorized and used by everyone. Within a bounded context apply tactical ddd patterns to define entities aggregates and domain services. A domain model with specific domain entities applies within a concrete bc or microservice. In your subdomain bounded.
Domain driven design ddd is a key and in our opinion a necessary tool when designing microservices be it breaking a monolith or implementing a greenfield project. Back when eric evans first published his seminal work domain driven. Domain subdomain domain vs subdomain domains subdomains difference domain names are mainly used as names for websites. Ways you can work around this paradox of domain model ddd and microservices.
Microservices io is brought to you by chris richardson. From domain driven design ddd. Microservices and domain driven design ddd are not only about bounded contexts although a fundamental tool for defining granularity of microservices there are other important concepts as well. Each bounded context contains a domain model that represents a particular subdomain of the larger application.
These are the same goals for microservices. The media domain project encompasses the microservice layer. A service often needs to publish events when it updates its data. The next layer of the diagram is labeled microservices.
Use the results from the previous step to identify the microservices in your application. Chris helps clients around the world adopt the microservice architecture through consulting engagements and training classes and workshops.
