Implementation Plan for Full Microservices Architecture

tip

This page is current and ready for use.

1. Infrastructure Setup​

  • API Gateway: Set up AWS API Gateway or Kong with GraphQL federation
  • Container Orchestration: Configure Kubernetes (EKS) with proper namespaces for each domain
  • Service Mesh: Implement Istio for advanced routing, resiliency, and observability
  • Message Broker: Deploy RabbitMQ for event-driven communication
  • Monitoring Stack: Set up Prometheus, Grafana, and Jaeger for observability
  • CI/CD Pipeline: Configure GitHub Actions or Jenkins for automated testing and deployment
  • Infrastructure as Code: Implement with Terraform or CloudFormation
  • Secrets Management: AWS Secrets Manager or HashiCorp Vault

2. Business Services Implementation (Priority Order)​

  1. Core Domain (Critical path)

    • Auth Service (JWT authentication, Cashfree for KYC)
    • User & Organization Service (profiles, preferences)
    • Payment Service (Payu & Cashfree integrations)

  2. AgroCare Domain (Core business functionality)

    • Inventory Service - Handles product catalog, inventory management, and quality control in one service
    • Order Service - Manages the complete order lifecycle including pricing, fulfillment, and delivery tracking
    • Supplier Service - Handles supplier relationships and procurement

  3. Notification Domain (Cross-cutting concern)

    • Notification Core Service
    • Templates Service
    • Delivery Services (SMS, Email, Push)

  4. Amagator Domain (Core business functionality)

    • Machinery Service (inventory management)
    • Booking Service (scheduling, availability)
    • Tracking Service (real-time location)

3. Guidelines for Service Implementation​

For each microservice:

  1. Create a dedicated repository
  2. Set up standard boilerplate with Symfony 7 + GraphQL
  3. Implement bounded context with clear domain models
  4. Define service API contracts in GraphQL schema
  5. Create Docker configuration
  6. Implement database migrations
  7. Set up service-specific tests
  8. Configure service-specific CI/CD pipeline

4. Communication Patterns​

  • Synchronous: GraphQL for client-initiated requests
  • Asynchronous: Event-based communication via RabbitMQ
  • Event Schema Registry: To maintain compatible event structures

5. Development Workflow​

  1. Local Development: Docker Compose for running dependent services
  2. Integration Testing: Kubernetes dev environment
  3. Staging: Complete replica of production with synthetic data
  4. Production: Gradual rollout with feature flags

6. Team Organization​

Consider organizing teams around domains rather than technical layers:

  • User Domain Team
  • AgroCare Domain Team
  • Amagator Domain Team
  • Each team responsible for their services end-to-end

This approach aligns perfectly with your complex architecture diagram, allowing you to build the exact system you've designed from the start. By implementing proper DevOps practices and infrastructure early, you'll avoid technical debt and be positioned for rapid scaling as OX Agry grows.
