Chapter 8: Reacting to Events with More Events
In Chapter 6, A Best Friend for the Frontend, and Chapter 7, Bridging Intersystem Gaps, we covered boundary service patterns. These services work at the boundary of the system, to support end users and external systems, and are responsible for catering to the kinds of changes driven by these actors.

- Dissecting the Control Service pattern
- Orchestrating business processes
- Employing the Saga pattern
- Calculating event-sourcing snapshots
- Implementing complex event processing (CEP) logic
- Leveraging machine learning...
