Finagle is a asynchronous, Netty based JVM RPC system made by Twitter which makes it easy to build high available clients and servers in Java and Scala. And it can even simplify your application architecture. Here I want to show you how powerful Finagle is.

One of the main principles of functional programming is to avoid side-effects. For the most part, working with immutable instances would be sufficient to satisfy that principle. But sometimes it's needed to do some sideeffects e.g. when we want to read from file. One straight-forward way of doing it is to get a `BufferedSource`, and process it using an iterator as shown below.

In part 1 of this series we learnt how to decouple the code that deals with side effects from our pure functions by using functors (Any type constructor which implements the map function). Now lets see how we can extend our functors so that we can sequence computations that each fall under the indeterminism of side effects.
