The microservices versus monolith debate didn’t end — it matured. Teams that scaled too early into distributed systems often paid coordination tax before they had product-market fit.
Our guidance: start with a modular monolith with clear domain boundaries, extract services only when independent scaling or deployment cadence justifies the overhead.
Key Takeaways
- Measure coupling and change frequency before you measure container count.
- Design for observability from day one — metrics, traces, and structured logs.
- Prefer incremental rollouts over big-bang migrations when systems carry revenue.
