The best tool for the job
The best tool we have to help manage complexity is composition. Functional programming to the rescue!
Our job is to decompose the elements of our system into atomic parts, fit them back together into subsystems and wire them together in a distributed, microservice based environment.
How do we know when have we sufficiently decomposed an element?
A: When we can treat the element as a black box, i.e., when we do not need visibility into the function to understand what it does.
