5. Message Broker (Pulsar/Redpanda) - NOUVEAU

Pour faciliter l'ingestion et le routage des données vers plusieurs backends (Prometheus, Context Brokers, etc.), un message broker sera ajouté entre les brokers MQTT et les services en aval.

Options préférées :

  • Apache Pulsar : Alternative cloud-native à Kafka, avec support natif des topics persistants et de la messagerie multi-tenant.
  • Redpanda : Compatible Kafka, mais sans dépendance ZooKeeper, plus simple à déployer.

Intégration avec FIWARE Scorpio :

  • Scorpio (Context Broker FIWARE) intègre nativement Kafka, ce qui facilitera l'interconnexion avec le message broker.

Nouveau flux de données :

MQTT Brokers (EMQX, Mosquitto, BunkerM)
    ↓
Message Broker (Pulsar/Redpanda)
    ↓ ↓ ↓
├─→ Context Brokers (Orion-LD, Stellio, Scorpio)
├─→ Prometheus (via exporter)
├─→ Time-Series DB (InfluxDB, CrateDB)
└─→ autres backends (OpenRemote, GeoServer, etc.)

6. Connexions Clés

  1. Traefik (:80/:443) : Reverse proxy pour tous les services exposés à l'hôte.
  2. Brokers MQTT (Mosquitto :1883, EMQX :11883) : Réception des données du simulateur et des capteurs IoT.
  3. Message Broker (Pulsar :6650/Redpanda :9092) : NOUVEAU - Ingest et routage vers les backends.
  4. Context Brokers (Orion-LD :2026, Stellio :8087, Scorpio :?) : Reçoivent les données NGSI-LD (Scorpio via Kafka natif).
  5. FROST-Server (:8090) : Stockage des données OGC SensorThings, connecté à PostgreSQL (frost_http-database-1).
  6. Grafana (:3001) : Visualisation des données depuis InfluxDB, Prometheus, et (via adaptateurs) Orion-LD/Stellio.
  7. OpenRemote (:8080) : Gestion des assets IoT, authentification via Keycloak, proxyé par Traefik.
  8. GeoServer (:8080) : Serveur de tuiles cartographiques, connecté au réseau FROST.
  9. Node-RED (:1880) : Alternative possible pour le simulateur IoT (projeté).
