Microservices are a scaling strategy for organizations and domains — not a default architecture for day one.
Stay with a modular monolith while a small team can ship features faster in one deployable unit.
Consider extraction when deploy coupling slows every team, when hot paths need independent scaling, or when ownership boundaries are clear.
Do not split by technical layer alone (frontend service / backend service). Split by business capability with clear data ownership.
Use a strangler pattern: route new traffic to new services gradually while the monolith keeps serving the rest.
Budget for the hidden costs: distributed tracing, contract testing, local developer experience, and on-call complexity.
Hemant Consultancy Services helps teams decide timing and execute extractions safely — especially for SaaS and fintech platforms under growth pressure.
