🏗️ System Architecture

Standardized Pattern

Every service follows the same architecture:

Service Structure:
├── app/
│   ├── services/
│   │   └── tenant_deletion_service.py (deletion logic)
│   └── api/
│       └── *_operations.py (deletion endpoints)

Endpoints per Service:
- DELETE /tenant/{tenant_id} (permanent deletion)
- GET /tenant/{tenant_id}/deletion-preview (dry-run)

Security:
- @service_only_access decorator on all endpoints
- JWT service token authentication
- Permission validation

Result Format:
{
  "tenant_id": "...",
  "service_name": "...",
  "success": true,
  "deleted_counts": {...},
  "errors": []
}

Deletion Orchestrator

DeletionOrchestrator
├── Parallel execution across 12 services
├── Job tracking with unique IDs
├── Per-service result aggregation
├── Error collection and logging
└── Status tracking (pending → in_progress → completed)

---

• Consistent base class pattern across all services
• Uniform API endpoint structure
• Standardized result format
• Common error handling approach

2. Safety

• Permission verification
• Audit log creation

4. Performance

• Expected completion: 20-60 seconds for full tenant

5. Maintainability

• Clear code organization
• Extensive documentation
• Test coverage
• Easy to extend pattern

💡 Design Decisions

Why This Architecture?

1. Base Class Pattern

   • Enforces consistency across services
   • Makes adding new services easy
   • Provides common utilities (safe_delete, error handling)

2. Preview Endpoints

   • Safety: See what will be deleted before executing
   • Compliance: Required for audit trails
   • Testing: Validate without data loss

3. Orchestrator Pattern

   • Centralized coordination
   • Parallel execution for performance
   • Job tracking for monitoring
   • Saga pattern foundation for rollback

4. Service-Only Access

   • Security: Prevents unauthorized deletions
   • Isolation: Only orchestrator can call services
   • Audit: All deletions tracked

---

📈 Business Value
