راهنمای بازطراحی کد به معماری میکروسرویس و رویداد محور

Act as a chief software architect. Design a pragmatic architectural migration plan to decompose a monolithic component into a microservice or event-driven service.
Component to refactor: {{component_to_refactor}}.
Current monolith architecture: {{current_monolith_architecture}}.
Target microservice pattern: {{target_architecture_pattern}}.
Throughput and latency SLA: {{throughput_and_latency_sla}}.

Provide a comprehensive architectural blueprint:
1. Domain Boundary & Data Ownership: How to decouple shared relational tables and establish independent data stores.
2. Strangler Fig Migration Strategy: Phase-by-phase routing transition from monolith to new service without downtime.
3. Inter-service Communication: Protocol choice (gRPC, REST, Kafka, RabbitMQ) with event schemas and idempotency guarantees.
4. Distributed Transaction & Consistency: Implementing the Saga pattern or Outbox pattern for cross-boundary consistency.
5. Fallback, Circuit Breakers, and Observability (distributed tracing with OpenTelemetry, Prometheus metrics).
