What is a bounded context in domain driven design?

A bounded context is simply the boundary within a domain where a particular domain model applies. Looking at the previous diagram, we can group functionality according to whether various functions will share a single domain model. Bounded contexts are not necessarily isolated from one another.

What are bounded contexts?

A bounded context is a defined part of software where particular terms, definitions and rules apply in a consistent way, Eric Evans explained in his keynote at DDD Europe earlier this year. A canonical context has a refined model and an expressive ubiquitous language with unambiguous definitions.

How do you determine the boundaries of Microservices?

Look at factors such as team size, data types, technologies, scalability requirements, availability requirements, and security requirements. These factors may lead you to further decompose a microservice into two or more smaller services, or do the opposite and combine several microservices into one.

What is the difference between subdomain and bounded context?

In DDD, a subdomain in the problem space is mapped to a bounded context in the solution space. A bounded context is an area of the application that requires its own ubiquitous language and its own architecture. Likewise, a subdomain is a segment of the domain, and a bounded context is a segment of the solution.

How do you determine bounded contexts?

To identify bounded contexts, you can use a DDD pattern called the Context Mapping pattern. With Context Mapping, you identify the various contexts in the application and their boundaries. It’s common to have a different context and boundary for each small subsystem, for instance.

What are domain boundaries?

Domain boundaries, i.e. interfaces between different orientation variants of the same crystal species, and phase boundaries, i.e. interfaces between two different modifications of the same compound, exhibit rather similar features.

How do you find bounded context?

Is bounded context a Microservice?

In the same vein, a Bounded Context consists a variety of components (microservices, web applications, mobile apps, databases, message queues, etc). It also serves as a logical barrier that encapsulates those components. Internally, the components can be coupled, and can freely pass data to each other.
