After identifying the bounded contexts in your system (as discussed in Chapter 6, “Maintaining the Integrity of Domain Models with Bounded Contexts,” and Chapter 7, “Context Mapping”), the next step is to decide how you will integrate them to carry out full business use cases. One of the big challenges you face in this process is successfully designing a robust distributed system. For example, each step of placing an order, billing the customer, and arranging shipping may belong to a different bounded context running as a separate piece of software on a separate physical machine or cloud instance. In this chapter, you learn about fundamental concepts in distributed computing that allow you to retain explicit domain concepts while gracefully dealing with nonfunctional ...
