# Microservices with .NET

Microservices can unlock team autonomy and independent scaling, but only when service boundaries and operational discipline are clear.

Design Fundamentals

Service Boundaries

  • Model services around business capabilities, not technical layers
  • Avoid shared databases across services
  • Keep contracts explicit and versioned
  • Communication Patterns

  • Sync: HTTP/gRPC for request-response flows
  • Async: queues/events for decoupled workflows
  • Use idempotency and retries for resilience
  • Platform Requirements

  • Containerization with Docker
  • Orchestration and service discovery
  • Centralized logging, metrics, and distributed tracing
  • Common Challenges

  • Distributed transactions and eventual consistency
  • Increased operational complexity
  • Contract governance across multiple teams
  • Debugging latency and failure cascades
  • When Microservices Make Sense

  • Multiple teams need independent release cadence
  • Different domains have different scaling profiles
  • Monolith evolution cost has become unacceptable
  • Conclusion

    Microservices are an organizational and architectural decision, not a default technical upgrade. Choose them when the business context truly requires them.

    I can help assess readiness and define a low-risk migration path.
