Episode notes
Iterative Architectural Design
- Iterate on architectural design before implementation.
- Use design tools to explore granularity and get feedback early, avoiding costly rework later.
Amazon's Granularity Adjustment
- Amazon's video monitoring software faced granularity issues, leading to adjustments, not monolith reversion.
- Many companies experience "rubber banding," oscillating between too small and too large services.
Initial Granularity Strategy
- Start with coarser-grained services and gradually refine as you learn.
- Understanding service characteristics guides granularity decisions.
