Existing Services (17 containers total)

MVP Platform Services (Microservices) - 7 services:

• mvp-platform-landing - Marketing/landing page (nginx)
• mvp-platform-tenants - Multi-tenant management API (FastAPI, port 8001)
• mvp-platform-vehicles-api - Vehicle data API (FastAPI, port 8000)
• mvp-platform-vehicles-etl - Data processing pipeline (Python)
• mvp-platform-vehicles-etl-manual - Manual ETL container (profile: manual)
• mvp-platform-vehicles-db - Vehicle data storage (PostgreSQL, port 5433)
• mvp-platform-vehicles-redis - Vehicle data cache (Redis, port 6380)
• mvp-platform-vehicles-mssql - Monthly ETL source (SQL Server, port 1433, profile: mssql-monthly)

Application Services (Modular Monolith) - 5 services:

• admin-backend - Application API with feature capsules (Node.js, port 3001)
• admin-frontend - React SPA (nginx)
• admin-postgres - Application database (PostgreSQL, port 5432)
• admin-redis - Application cache (Redis, port 6379)
• admin-minio - Object storage (MinIO, ports 9000/9001)

Infrastructure - 3 services:

Current Limitations Identified

1. Single Network: All services on default network (no segmentation)
2. Manual Routing: nginx configuration requires manual updates for new services
3. Port Exposure: Many services expose ports directly to host
4. Configuration: Environment variables scattered across services
5. Service Discovery: Hard-coded service names in configurations
6. Observability: Limited monitoring and debugging capabilities
