Episode notes
Modularity vs. Granularity
- Embrace modularity, but be wary of granularity.
- Modularity is about breaking systems into parts, while granularity concerns their size.
Service Sizing Nuances
- There's no single answer to ideal service size; it depends on context.
- Avoid overly micro services, as they create coordination overhead and transactional difficulties.
Iterative Architectural Design
- Iterate on architectural design before implementation.
- Use design tools to explore granularity and get feedback early, avoiding costly rework later.
