Simple components - simple components consisting of few subdomains are easier to understand and maintain than complex components.How to organize the subdomains into one or more deployable/executable components? Forces It mutates and queries business entities in one or more subdomains. The subdomains implement the application’s behavior, which consists of a set of (system) operations.Īn operation is invoked in one of three ways: synchronous and asynchronous requests from clients events published by other applications and services and the passing of time. DDD aggregates) that implement business rules, and adapters, which communicate with the outside world.Ī Java-based subdomain, for example, consists of classes organized into packages that’s compiled into a JAR file.
It consists of business logic, which consists of business entities (a.k.a. The team delivers a stream of small, frequent changes that are tested by an automated deployment pipeline and deployed into production.Ī team is responsible for one or more subdomains.Ī subdomain is an implementable model of a slice of business functionality, a.k.a. In particular, it practices continuous deployment. You need to deliver changes rapidly, frequently and reliably - as measured by the DORA metrics - in order for your business to thrive in today’s volatile, uncertain, complex and ambiguous world.Ĭonsequently, your engineering organization is organized into small, loosely coupled, cross-functional teams.Įach team delivers software using DevOps practices as defined by the DevOps handbook. You are developing a business-critical enterprise application. In my workshop, you will learn about to use Assemblage to design a microsevice architecture for your application. Take a look at Assemblage, a microservice architecture definition process.
