Scalable Backend Architecture in Real Projects

A practical approach to designing scalable backend architecture based on real production experience.

Scalable backend architecture is not about using microservices everywhere.

The goal is to design systems that can grow without unnecessary complexity.

### Key Architectural Principles

- Modular design

- Loose coupling

- Clear domain boundaries

### Common Approaches

- Modular monolith for early-stage systems

- Microservices when scaling teams or domains

- Event-driven architecture for decoupling

A scalable system evolves over time, and architecture should support

that evolution instead of blocking it.
