Learning Functional Programming in Go

Applying FP at the Architectural Level

Most Functional programming (FP) books only talk about the code level benefits but FP principles provide better returns when applied at the architecture level. 

In this chapter, we will discuss some architectural styles that are based on the same ideas and philosophies of FP.

We'll also build a layered application that solves the problem of circular dependencies with the aid of Inversion of Control (IoC) to control the flow of logic. The application we build allows an admin to move files between two cloud storage service provider accounts.
