I was reminded of this article (https://blog.cleancoder.com/uncle-bob/2014/10/01/CleanMicros...) from Uncle Bob while reading this paper.

From the article:

> The Deployment Model is a Detail.

> If the code of the components can be written so that the communications mechanisms, and process separation mechanisms are irrelevant, then those mechanisms are details. And details are never part of an architecture.

> That means that there is no such thing as a micro-service architecture. Micro-services are a deployment option, not an architecture.
