Once you're comfortable with the basic and intermediate usage of concurrency features in Go, you may find that you're able to handle the majority of your development use cases with bidirectional channels and standard concurrency tools.
In Chapter 2, Understanding the Concurrency Model, and Chapter 3, Developing a Concurrent Strategy, we looked at the concurrency models, not just of Go but of other languages as well, and compared the way they—and distributed models—can work. In this chapter, we'll touch on those and some higher level concepts with regard to designing and managing your concurrent application.
In particular, we're going to look at central management of goroutines and their associated channels—out of the box you may find goroutines to be a set-it-and-forget-it proposition; however, there are cases where we might want more granular control of a channel's state.
