An introduction to architectural thinking through the 4 dimensions: characteristics, solutions, logical components and architectural styles.
Original
TranslatedThis book is useful as entry into architectural thinking: It provides a simple and practical 4-dimensional framework that can be used in real design discussions and in preparation for System Design interviews.
4 dimensions of architecture
1. Architectural Characteristics
Non-functional properties that determine the behavior of the system: performance, scalability, fault tolerance, testability and others.
2. Architectural Decisions
Decisions with a long horizon of influence: choice of style, service boundaries, data approach, integration and operational practices.
3. Logical Components
Logical blocks and their responsibilities: which parts of the system implement key functions and how these parts interact.
4. Architectural Styles
The form of the system at the level of structure and deployment: layered, modular monolith, microservices, event-driven and compromises of each approach.
Design algorithm according to the book
Step 1
Define characteristics
From the requirements, select 3-5 priority quality attributes and agree on what the system can sacrifice.
Step 2
Record decisions
Make architectural decisions that support the selected characteristics and explicitly describe trade-offs.
Step 3
Design components
Break the system into logical blocks with clear boundaries of responsibility and interactions.
Step 4
Choose an architectural style
Choose a style that is consistent with the characteristics, solutions and realities of the team/platform.
How the book is organized
Chapters 1-5
Basic principles and 4 dimensions
An introduction to architectural thinking, characteristics, trade-offs, logical components, and style classification.
Chapters 6-11
Analysis of architectural styles
Layered, modular monolith, microkernel, microservices and event-driven with evaluation based on a set of characteristics.
Chapter 12 + Appendix
Practice and the role of the architect
Final design exercise and applied topics about the work of an architect and professional growth.
Practical conclusions
Use the 4D frame as a template for architectural workshops and design reviews.
Don't start with technology: first characteristics, then solutions and components.
Explicitly document trade-offs rather than “optimize everything at once.”
Compare styles not by taste, but by characteristics critical to the product.
