# Lizenzserver - Architektur & Implementierungsplan
|
|
|
|
## Übersicht
|
|
Der Lizenzserver ist das zentrale Herzstück des v2-Docker Systems, das für die Validierung, Verwaltung und Überwachung aller Lizenzen verantwortlich ist. Diese Dokumentation beschreibt eine zukunftssichere Architektur, die von Anfang an auf Skalierbarkeit, Wartbarkeit und Erweiterbarkeit ausgelegt ist.
|
|
|
|
## Architektur-Prinzipien (Kein Refactoring nötig!)
|
|
|
|
### 1. **Klare Trennung von Anfang an**
|
|
- **API Layer**: Strikte Trennung zwischen Public API (Clients) und Admin API
|
|
- **Business Logic**: Zentral in Service-Klassen, nicht in Routes
|
|
- **Data Access**: Repository Pattern für alle DB-Zugriffe
|
|
- **No Spaghetti Code**: Keine Vermischung von Präsentation und Logik
|
|
|
|
### 2. **Konsistente Namenskonventionen**
|
|
```python
|
|
# Datenbank-Felder (snake_case, eindeutig)
|
|
is_active # NICHT: active
|
|
hardware_id # NICHT: device_id
|
|
created_at # NICHT: created
|
|
updated_at # NICHT: updated
|
|
is_test # NICHT: test
|
|
|
|
# API Responses (camelCase für JSON)
|
|
{
|
|
"licenseId": "uuid",
|
|
"isActive": true,
|
|
"hardwareId": "hash",
|
|
"createdAt": "2025-01-18T10:00:00Z"
|
|
}
|
|
|
|
# Python (snake_case)
|
|
def validate_license(license_key: str, hardware_id: str) -> dict:
|
|
pass
|
|
```
|
|
|
|
### 3. **Modulare Service-Architektur**
|
|
```python
|
|
# services/license_service.py
|
|
class LicenseService:
|
|
def __init__(self, db_repo, cache_repo, event_bus):
|
|
self.db = db_repo
|
|
self.cache = cache_repo
|
|
self.events = event_bus
|
|
|
|
def validate_license(self, key, hw_id):
|
|
# Business Logic hier, NICHT in Routes!
|
|
pass
|
|
|
|
# routes/api_routes.py
|
|
@api.route('/validate')
|
|
def validate():
|
|
# NUR Request handling, keine Business Logic
|
|
data = request.get_json()
|
|
result = license_service.validate_license(
|
|
data['licenseKey'],
|
|
data['hardwareId']
|
|
)
|
|
return jsonify(result)
|
|
```
|
|
|
|
### 4. **Event-Driven Architecture**
|
|
```python
|
|
# Lose Kopplung durch Events
|
|
class EventBus:
|
|
def publish(self, event_type, data):
|
|
# Analytics Service hört zu
|
|
# Audit Service hört zu
|
|
# Email Service hört zu
|
|
pass
|
|
|
|
# Neue Features = Neue Listener, kein Code ändern!
|
|
```
|
|
|
|
### 5. **Klare API-Struktur**
|
|
```
|
|
/api/license/validate # Einheitliche API ohne Versionierung
|
|
/api/license/activate # Konsistente Endpoints
|
|
/api/admin/license/status # Klare Trennung Admin vs. Public
|
|
```
|
|
|
|
### 6. **Feature Flags von Anfang an**
|
|
```python
|
|
if feature_flags.is_enabled('anomaly_detection'):
|
|
anomaly_service.check(license_id)
|
|
# Neue Features ohne Deployment aktivieren
|
|
```
|
|
|
|
### 7. **Dependency Injection**
|
|
```python
|
|
# Keine harten Dependencies!
|
|
def create_app(config):
|
|
db = Database(config.db_url)
|
|
cache = Redis(config.redis_url)
|
|
|
|
# Services bekommen Dependencies injiziert
|
|
license_service = LicenseService(db, cache)
|
|
|
|
# Routes bekommen Services injiziert
|
|
api_blueprint = create_api_routes(license_service)
|
|
|
|
app.register_blueprint(api_blueprint)
|
|
return app
|
|
```
|
|
|
|
### 8. **Klare Verzeichnisstruktur**
|
|
```
|
|
lizenzserver/
|
|
├── api/
|
|
│ ├── v1/
|
|
│ │ ├── routes/

|
|
├── events/ # Event System
|
|
├── utils/ # Helpers
|
|
└── tests/ # Umfassende Tests!
|
|
```
|
|
|
|
### 9. **Database Migrations von Anfang an**
|
|
```python
|
|
# Alembic/Flyway für versioned migrations
|
|
# NIEMALS manuelle SQL changes!
|
|
alembic revision -m "add_anomaly_detection_table"
|
|
alembic upgrade head
|
|
```
|
|
|
|
### 10. **Dokumentation als Code**
|
|
```python
|
|
# OpenAPI/Swagger von Anfang an
|
|
from flask_restx import Api, Resource, fields
|
|
|
|
api = Api(doc='/docs')
|
|
|
|
@api.route('/license/validate')
|
|
class LicenseValidation(Resource):
|
|
@api.doc('validate_license')
|
|
@api.expect(license_model)
|
|
@api.marshal_with(validation_result)
|
|
def post(self):
|
|
"""Validate a license key with hardware ID"""
|
|
pass
|
|
```
|
|
|
|
## Kernfunktionen
|
|
|
|
### 1. Lizenzvalidierung
|
|
- **Online-Validierung**: Echtzeit-Prüfung von Lizenzen
|
|
- **Offline-Grace-Period**: 72h Offline-Betrieb mit gecachten Tokens
|
|
- **Hardware-Binding**: Geräte-spezifische Lizenzierung
|
|
- **Multi-Device-Support**: Verwaltung mehrerer Geräte pro Lizenz
|
|
|
|
### 2. Aktivierungsmanagement
|
|
- **Erste Aktivierung**: Hardware-ID Registrierung
|
|
- **Re-Aktivierung**: Bei Hardware-Wechsel
|
|
- **Deaktivierung**: Manuell oder automatisch
|
|
- **Transfer**: Lizenz auf neues Gerät übertragen
|
|
|
|
### 3. Nutzungsüberwachung
|
|
- **Heartbeat-System**: Regelmäßige Lebenszeichen
|
|
- **Usage-Tracking**: Detaillierte Nutzungsstatistiken
|
|
- **Anomalie-Erkennung**: Verdächtige Aktivitäten
|
|
- **Concurrent-Use-Prevention**: Mehrfachnutzung verhindern
|
|
|
|

|
## API-Endpunkte
|
|
|
|
### Public API (Client-Software)
|
|
|
|
```yaml
|
|
# Lizenz-Validierung
|
|

|
|

|
|

|
|
app_version: string
|
|
|
|

|
|
|
|

|
|
Authorization: Bearer {token}
|
|
Body:
|
|
duration_hours: number (max: 72)
|
|
```
|
|
|
|
### Admin API (Admin Panel)
|
|
|
|
```yaml
|
|
# Lizenz-Details mit Echtzeit-Status
|
|
GET /api/v1/admin/license/{id}/status
|
|
Response:
|
|
license_info: object
|
|
active_devices: array
|
|
recent_activity: array
|
|
anomalies: array
|
|
|
|
# Geräte-Management
|
|
DELETE /api/v1/admin/license/{id}/device/{hardware_id}
|
|
POST /api/v1/admin/license/{id}/transfer
|
|
Body:
|
|
from_hardware_id: string
|
|
to_hardware_id: string
|
|
|
|
# Anomalie-Management
|
|
GET /api/v1/admin/anomalies
|
|
PATCH /api/v1/admin/anomaly/{id}/resolve
|
|
```
|
|
|
|
## Sicherheitskonzepte
|
|
|
|
### 1. **Token-Strategie**
|
|
```python
|
|
# JWT Token Struktur
|
|
{
|
|
"sub": "license_id",
|
|
"hwid": "hardware_id",
|
|
"exp": timestamp,
|
|
"iat": timestamp,
|
|
"features": ["feature1", "feature2"],
|
|
"limits": {
|
|
"api_calls": 1000,
|
|
"concurrent_sessions": 1
|
|
}
|
|
}
|
|
```
|
|
|
|
### 2. **Rate Limiting**
|
|
- Per API Key
|
|
- Per License
|
|
- Per IP Address
|
|
- Sliding Window Algorithm
|
|
|
|
### 3. **Encryption**
|
|
- License Keys: AES-256-GCM
|
|
- API Communication: TLS 1.3
|
|
- Database: Transparent Data Encryption
|
|
- Backups: GPG Encryption
|
|
|
|
## Monitoring & Observability
|
|
|
|
### Metriken (Prometheus)
|
|
```yaml
|
|
# Business Metrics
|
|
license_validations_total
|
|
license_activations_total
|
|
active_licenses_gauge
|
|
license_revenue_total
|
|
|
|
# Technical Metrics
|
|
api_request_duration_seconds
|
|
database_query_duration_seconds
|
|
cache_hit_ratio
|
|
error_rate
|
|
```
|
|
|
|
### Logging (ELK Stack)
|
|
```json
|
|
{
|
|
"timestamp": "2025-01-18T10:00:00Z",
|
|
"level": "INFO",
|
|
"service": "license-api",
|
|
"trace_id": "uuid",
|
|
"event": "license_validation",
|
|
"license_id": "uuid",
|
|
"hardware_id": "hash",
|
|
"result": "success",
|
|
"duration_ms": 23
|
|
}
|
|
```
|
|
|
|
### Alerting
|
|
- License-Abuse Detection
|
|
- System Health Checks
|
|
- Performance Degradation
|
|
- Security Incidents
|
|
|
|
## Skalierungsstrategien
|
|
|
|
### Horizontal Scaling
|
|
1. **Stateless Services**: Alle Services zustandslos
|
|
2. **Load Balancing**: Round-Robin mit Health Checks
|
|
3. **Auto-Scaling**: CPU/Memory basiert
|
|
4. **Database Read Replicas**: Für Read-Heavy Operations
|
|
|
|
### Caching-Strategie
|
|
```yaml
|
|
Cache-Layer:
|
|
- Redis Cluster
|
|
- TTL: 5 Minuten für Validierungen
|
|
- Invalidation: Event-basiert
|
|
|
|
Cache-Keys:
|
|
- license:{id}:status
|
|
- license:{id}:devices
|
|
- hardware:{id}:licenses
|
|
- token:{token}:valid
|
|
```
|
|
|
|
### Queue-basierte Verarbeitung
|
|
- Heartbeat Processing
|
|
- Email Notifications
|
|
- Report Generation
|
|
- Batch Operations
|
|
|
|

### Admin Panel Routes (Neue)
|
|
```python
|
|
# Lizenzserver Monitoring
|
|
@app.route('/lizenzserver/monitor')
|
|
@app.route('/lizenzserver/analytics')
|
|
@app.route('/lizenzserver/anomalies')
|
|
@app.route('/lizenzserver/config')
|
|
|
|
# API für Live-Updates
|
|
@app.route('/api/admin/lizenzserver/live-stats')
|
|
@app.websocket('/ws/lizenzserver/updates')
|
|
```
|
|
|
|
## Fazit
|
|
|
|
Diese Architektur ist darauf ausgelegt, von Anfang an skalierbar und wartbar zu sein. Durch die Microservices-Architektur, Event-Driven Design und sorgfältige Planung der Datenbankstruktur wird sichergestellt, dass zukünftige Erweiterungen ohne größere Refactorings möglich sind.

**Wichtig**: Alle Lizenzserver-Funktionen sind vollständig im Admin Panel integriert und bieten eine einheitliche Oberfläche für die Verwaltung. Die Implementierung sollte schrittweise erfolgen, wobei jede Phase vollständig getestet wird, bevor zur nächsten übergegangen wird. Besonderes Augenmerk sollte auf Security, Performance und Monitoring gelegt werden, da diese Aspekte für einen Lizenzserver kritisch sind. |
