Month 11: Microservices Transition - Detailed Roadmap

Week 1: Initial Microservices
Extract inventory service from monolith
Create API gateway implementation
Build service discovery mechanism
Implement message broker (RabbitMQ/Kafka)
Create service authentication
Week 2: Microservices Infrastructure
Build deployment pipeline for services
Implement centralized logging
Create service health monitoring
Build circuit breaker implementation
Implement containerization (Docker)
Week 3: Additional Microservices
Extract order processing service
Create search service implementation
Build notification service
Implement payment processing service
Create service documentation
Week 4: Advanced Service Architecture
Build service versioning strategy
Implement distributed tracing
Create service metrics collection
Build fault tolerance mechanisms
Implement data consistency patterns

Service Configuration Management

Create centralized configuration management for all microservices

Implement feature flags at the service level to control functionality across the platform

Technical Implementation Details

• Service Architecture: Domain-driven microservices with bounded contexts
• Communication: Both synchronous (REST/gRPC) and asynchronous (message queue) patterns
• API Gateway: Single entry point with routing, authentication, and rate limiting
• Service Discovery: Dynamic service registration and discovery
• Resiliency: Circuit breakers, retries, and fallback mechanisms

Month 11 Deliverables

• Core microservices extracted from monolith (inventory, orders, search)
• API gateway with routing and authentication
• Message broker implementation for async communication
• Service monitoring and distributed tracing
• Containerization and deployment pipeline
• Comprehensive service documentation
