## Estimated Timeline

- **Phase 1 (Infrastructure)**: 2-4 hours
- **Phase 2 (Kubernetes)**: 1-2 hours
- **Phase 3 (Besu Network)**: 2-3 hours
- **Phase 4 (Contracts)**: 1-2 hours

- **Phase 9 (Production)**: 2-4 hours

**Total Estimated Time**: 14-26 hours

## Critical Dependencies

1. **Quota Availability**: All 24 regions must have 10+ vCPUs available
2. **Network Connectivity**: Cross-region connectivity required
3. **Validator Keys**: 48 validator key pairs must be generated securely
4. **CCIP Funding**: LINK tokens required for CCIP operations
5. **Contract Deployment**: ETH required for Mainnet deployments

## Risk Mitigation

1. **Quota Issues**: Monitor quota usage, request increases if needed
2. **Network Issues**: Test connectivity before deployment
3. **Key Management**: Use Azure Key Vault for secure key storage
4. **Funding**: Ensure sufficient LINK and ETH before deployment
5. **Rollback Plan**: Document rollback procedures for each phase
