Aujourd'hui accessibles partout, les objets connectés suscitent de plus en plus d’intérêt. Malgré cela, l’implémentation d’un projet IoT peut s’avérer compliquée au vu la diversité des dispositifs, protocoles et frameworks. Le nombre d'alternatives qui se présentent à nous est énorme. En partant de l'embarqué, avec les protocoles applicatifs, jusqu'au déploiement d'une solution sur le cloud, en passant par la délégation des traitements en local via l'IoT Edge, nous rentrerons dans le détail de l'implémentation d'une solution IoT de bout en bout, le tout en comparant deux solutions : AWS et Azure.

“Edge computing is a method of
optimizing cloud computing systems by
performing data processing at the edge of
the network, near the source of the data”
source: Hackernoon

Benefits of edge computing
19
● Decentralized processing
● Reliability
● Processing close to data source
● Select data and insights flow to the cloud
● Low latency
● Privacy and data protection
● Authentification
