Component, connector, and coordination have been key concepts exploited in different communities to manage the complexity of concurrent and distributed system development. In this paper, we discuss three approaches within three different classes: composition in software architectures, coordination models, and programming abstractions for concurrency. These classes encompass different perspectives and solutions to face crucial challenges in developing concurrent and distributed systems. The approaches are discussed with respect to some characteristics of interest for the above classes: compositionality, incrementality, scalability, compositional reasoning, reusability, and evolution.
