Hands-On Microservices with Kotlin

From the monolith to microservices

So, why did SoA evolve into microservices? Perhaps one of the reasons was due to the monolith. There was a point in time where applications were small, and the presentation logic was usually coupled with the business logic. Then, the domain model got complex and many software patterns arose. Most of them were focusing on one thing: Separation of Concerns.

Separation of Concerns (SoC) is a design principle for separating software into distinct sections so that each section addresses only one concern. But software is not the only thing that needs separation; the architecture needs it as well. Things like SoA are designed for that, as it allows us to hide our complexity behind black boxes to make our architecture ...
