The API of this service is represented as a set of commands and queries it consumes and events it publishes. The core of the service is its business logic, which is surrounded by adapters that communicate with other services and applications.

deploy command and query components as two independent services (CQRS), and extract their HTTP/REST adapters/controllers to services as well (location transparency).

deploy command and query components separately ( CQRS), as two independent services.

deploy all components within one service.

This design enables different deployment strategies with different scalability options, for example: It’s simply a matter of configuration whether the system runs on a single node or is distributed on several nodes. These components aren’t interested in the actual destination of a message. Additionally, these components communicate via messages (commands, events, queries) transparently. In Axon applications, the CQRS architectural pattern decouples command components from the query side components. Let’s introduce a sample subdomain of Shipping management responsible for managing courier information and contains a courier view of an order ( shipping) for managing the delivery of orders.

Bounded Contexts are a strategic concept in Domain Driven Design, and it is important to know how it is reflected in the architecture and organizational/team structure. In Axon applications, the contract (API) is represented as a set of messages (commands, events, and queries) that the application publishes and consumes.

As the model starts to take on a deeper meaning and clarity, Bounded Contexts will transition to the 'solution space', with the software model being reflected in project source code.īounded Contexts represent logical boundaries from a run-time perspective, defined by contracts within software artifacts where the model is implemented. In this phase, the task is to find the actual boundaries of specific contexts and then visualize the relationships between these contexts. When starting with software modeling, Bounded Contexts are conceptual and are part of the 'problem space'. The domain model expresses a Ubiquitous Language as a software model. 'A Context is the setting in which a word or statement appears, and that determines its meaning'.Ī Bounded Context is an explicit boundary within which a domain model exists.
