Components communicate by publishing notifications about occurred events and by subscribing to those notifications of interest. In this thesis, we develop structuring means to modularly design and engineer large-scale event-based infrastructures. In particular, we present a composable architecture for publish/subscribe brokers, a scoping concept to limit the forwarding of notifications, and corresponding programming abstractions for event-driven applications.
