Orientation IOT EDGE

https://docs.microsoft.com/en-us/azure/iot-edge/tutorial-csharp-module

Un module par sensor / action, cela crée un "genre" api pour les device edge, ex :

[Get] deviceId/sensor/hc04

[Post] deviceId/output/light

Possible de lancer un handle qui écoute la distance et envois au hub.

Avantage :

• Utilisation du EDGE
• Utilisation de docker
• Un module = 1 sensor / Single Responsability

Inconvénient :

• Un peu plus chaud a faire

Flux (Ma vision)

1. On formate les devices, avec une image type.

2. Au lance du device, celui-ci génére un ID unique et est register dans un groupe "Admin Stock"

3. Quand un projet est crée, la personne peux "commander X" devices

4. A ce moment, le module de provisioning, vas réecrire le yaml de configuration du edge, pour se binder sur les informations du projet a) Un enrollement group est crée pour le projet et celui-ci est utiliser pour les devices

5. Une dois réecris le module reboot

6. Les devices doivent à présent apparaitre dans le Enrollment Group du projet
