hardmigrate-monolith-to-microservices
How would you migrate a monolith to microservices without breaking users?
Answer
A safe migration is incremental.
**Steps:**
- Identify clear domain boundaries (bounded contexts)
- Extract one service at a time (strangler pattern)
- Keep API contracts stable; use a gateway if needed
- Handle data ownership carefully (avoid shared DB long-term)
- Add observability early (tracing/logs)
Microservices only help if the team can operate them reliably (deployments, monitoring, incident response).
