Architecture Patterns
How you organize your system determines how it scales, how it fails, and how your team works.
The big architectural decisions. Monolith vs microservices isn't a binary choice — it's a spectrum, and understanding where you are on that spectrum is what matters.
Topics
| Chapter | What It Covers |
|---|---|
| Monolithic Architecture | Single deployable unit, modular monolith |
| Microservices | Service decomposition, bounded context, service mesh |
| Serverless | FaaS, BaaS, cold starts, durable functions |
| Event-Driven | Choreography vs orchestration, saga, data consistency |
| Domain-Driven Design | Bounded context, aggregates, entities, domain events |
| Twelve-Factor App | The methodology for building modern SaaS |
The Decision Framework
Ask yourself:
- Team size — can your team own separate services?
- Domain complexity — is the business logic separable?
- Scale requirements — do different parts need different scaling?
- Operational maturity — can you run distributed systems?
Start monolith. Split when the pain of staying together exceeds the pain of splitting.
