Introduction

The platform stack is a large body of concepts, principles, entities and their relationships. To master the architecture of a stack is to understand the model and to be able to operate it, that is, to represent the use cases and directions of its possible application and development.

A model is an integral system of knowledge about an object, about important aspects of its functioning from the point of view of the problem to be solved, understanding of all principles driving its development in their mutual connection.

The goal is to provide an approach to mastering the model that will increase understanding step by step from the beginning, focus only on what is important - details can be derived as implications or assumptions from what has already been learned.
