# AITBC Microservices Migration Status

## Overview

This document tracks the migration of the AITBC monolithic coordinator-api to a microservices architecture.

**Legacy Port Warning**: The coordinator API previously ran on port **8000**. This is now a **legacy port**. The current architecture uses:
- **Agent Coordinator**: Port 9001 (replaces coordinator API)
- **Exchange API**: Port 8001
- **Marketplace Service**: Port 8102
- **GPU Service**: Port 8101
- **Trading Service**: Port 8104

## Next Steps

### Migration Complete

The microservices migration is now complete. All coordinator-api functionality has been migrated to dedicated microservices, and the legacy coordinator-api service has been disabled on all nodes.

### Optional Cleanup

The following optional cleanup steps can be performed:

1. **Remove coordinator-api service files** from all nodes
2. **Drop legacy database** (aitbc) if no longer needed
3. **Update API Gateway** to remove coordinator-api routing
4. **Update CLI configuration** to remove coordinator_url reference

## Systemd Services

All microservices are managed by systemd:

- `aitbc-gpu.service` - GPU Service (port 8101)
- `aitbc-marketplace.service` - Marketplace Service (port 8102)
- `aitbc-trading.service` - Trading Service (port 8104)
- `aitbc-governance.service` - Governance Service (port 8105)
- `aitbc-ai.service` - AI Service (port 8106)
- `aitbc-monitoring.service` - Monitoring Service (port 8107)
- `aitbc-hermes.service` - hermes Service (port 8108)
- `aitbc-plugin.service` - Plugin Service (port 8109)
- `aitbc-api-gateway.service` - API Gateway (port 8080)
- `aitbc-coordinator-api.service` - Legacy Coordinator API (port 8000) - **DISABLED**

## Database Schema

Each microservice has its own PostgreSQL database:

- `aitbc_gpu` - GPU Service database
- `aitbc_marketplace` - Marketplace Service database
- `aitbc_trading` - Trading Service database
- `aitbc_governance` - Governance Service database
- `aitbc` - Coordinator API database (legacy)

## Testing

- Unit tests created for all microservices (pytest)
- API Gateway routing tested for all services
- CLI commands tested with new microservices
- Health endpoints verified for all services

## Issues Resolved

1. **Async session dependency issue**: Fixed in all microservices by creating `get_session_dep()` function
2. **Model import errors**: Fixed by using correct model names from domain files
3. **CLI argument parsing**: Updated CLI handlers to use microservice URLs
4. **API Gateway routing**: Verified all services routing correctly

## Conclusion

The microservices migration is progressing well. The core GPU and marketplace functionality has been successfully migrated to dedicated microservices. The CLI has been updated to use the new microservices, and the API Gateway is routing requests correctly.

The remaining coordinator-api functionality is more complex and involves multiple domains. A phased approach is recommended to complete the migration without disrupting existing functionality.
