Milestone 13 - Production Hardening

Summary

Production readiness: monitoring, error handling, scalability, and reliability improvements.

Weeks 27-28

Make the system production-ready with comprehensive monitoring, error handling, and scalability.

✅ Monitoring & Observability:
- Application monitoring (error tracking, performance)
- Database monitoring
- Queue monitoring
- Alerting system
✅ Error Handling:
- Comprehensive error handling across all agents
- Error recovery mechanisms
- Dead letter queue for failed jobs
- Error notification system
✅ Scalability:
- Horizontal scaling support
- Database connection pooling
- Queue concurrency optimization
- Caching strategy implementation
✅ Security:
- API security hardening
- Data encryption
- Rate limiting
- Input validation

✅ Production-Ready Orchestrator:
- High availability (multiple orchestrator instances with leader election)
- Comprehensive error handling and retries
- Pipeline monitoring and metrics
- Instance health monitoring and automatic failover
- Load balancing optimization
- Job queue management and prioritization
✅ Newsletter pipeline enhancements:
- Parallel execution support:
  - Parallel analysis for multiple tickers
  - Sequential content generation per user (maintained)
  - Parallel delivery
- Data freshness management:
  - Checks data freshness before analysis
  - Triggers immediate data collection if data is stale via HTTP endpoint
  - Handles data collection agent running independently
✅ Better error handling and retries
✅ Pipeline monitoring and metrics
✅ Instance management production hardening:
- Automatic instance recovery
- Instance health checks
- Graceful instance termination
- Instance capacity optimization

✅ All API services (Agent Auth, Registry, Data) are production-ready with high availability
✅ Hermes Orchestrator is production-ready with high availability and instance management
✅ Instance management is robust (automatic recovery, health checks, graceful termination)
✅ System handles errors gracefully across all components
✅ Monitoring provides visibility into system health (all services, orchestrator, instances)
✅ Email delivery works reliably (99%+ success rate)
✅ System can handle increased load (horizontal scaling works for all components)
✅ Admin dashboard provides necessary controls (including API services and orchestrator monitoring)
✅ All critical errors trigger alerts
✅ All services have proper security hardening (rate limiting, input validation, encryption)

After this milestone, system is production-ready. Milestone 14 will add advanced learning and self-improvement.
