Software Architecture
Software architecture is the high-level structure of a system — its major components, how they interact, and the principles that guide its design and evolution over time, made early and hard to change later.
Why architecture matters
Architecture decisions are among the most expensive to reverse. Choosing a monolith versus microservices, a relational versus NoSQL database, or synchronous versus event-driven communication shapes everything downstream: how fast teams can ship, how the system scales, and how much technical debt accumulates.
Code Ninety's systems architects design for the client's actual scale and constraints, not for hypothetical future requirements — over-engineering an architecture for scale you don't need wastes budget just as surely as under-engineering one that can't handle real load.
Common architectural patterns
| Pattern | Best for |
|---|---|
| Monolith | Small teams, early-stage products, simpler deployment |
| Microservices | Large teams, independent scaling, complex domains |
| Event-driven | Loosely coupled systems reacting to state changes |
| Layered (N-tier) | Clear separation between presentation, business, and data layers |
| Serverless | Variable, unpredictable load; minimal ops overhead |
