This document discusses the relationship between the Actor Model and Domain-Driven Design (DDD). It explains that the Actor Model concepts of isolation, asynchrony, and message-driven behavior align well with DDD principles. The document also describes how the Akka framework supports the Actor Model and can help build reactive systems using DDD. It argues that actors serving as DDD aggregates is a natural fit, as both are focused on messaging for coordination and isolation of state.

30. Actors and DDD

31. “The Actor Model retained more of
what I thought were the good features
of the object idea.”
“The big idea is messaging…”
[Alan Kay]

32. “The essence of Domain Design Driven
is modeling a ubiquitous language in a
bounded context.”
[Evans]
