Software Architecture Examples - Monolith to Microservices
Explore software architecture examples: monolith, microservices, event-driven and serverless. Choices that scale.
Architecture choices determine the scalability and maintainability of your system. A monolith can be perfect for an MVP; microservices become relevant at team scale and independent deployment.
Modular monolith for startup
A scale-up built a modular monolith with clear package boundaries. Modules communicate via interfaces, not directly. Later extraction to services possible.
- Bounded contexts as packages
- Dependency rule: inner layers no outer imports
- Database per module (schema) where possible
Event-driven microservices for real-time platform
A real-time platform used Kafka as event bus. Services published events; others consumed asynchronously. Loose coupling and scalable consumption.
- Events as first-class citizens
- Idempotent consumers
- Schema registry for contract evolution
Key takeaways
- Start simple — monolith is often the right choice for v1.
- Modular monolith makes later extraction easier.
- Microservices add operational complexity; only when the team and use case justify it.
