Architecture
Learn Software Architecture
Architecture is the set of structural decisions about how a system is divided up, how the parts communicate, and which qualities the design protects.
Why teams use it
- Good boundaries let a codebase keep growing without every change becoming risky.
- It makes trade-offs explicit rather than accidental.
- It gives a team a shared mental model of the system.
Where you will meet it
Whether business rules can be tested without a database running is an architectural outcome, not a coding style preference.
What to learn, and in what order
Work through these roughly in order. Jumping to the advanced list before the basics are solid is the most common way people get stuck.
Beginner
- What architecture actually means
- Separation of concerns
- Layered structure
- Why dependencies point inwards
Intermediate
- SOLID principles in practice
- Repository and factory patterns
- Clean architecture
- Modular structure
Advanced
- CQRS and when it is overkill
- Event-driven design
- Microservices trade-offs
- Resilience, caching and messaging
