Abstract the actual communication protocols via “protocol adapters”

Deploy on:

An Integration Platform for IoT Services

NoSQL data store

REST API

Eclipse Hono

Eclipse Hono provides a uniform API for interacting with millions of devices connected to the cloud via arbitrary protocolsExample:

<<Protocol Adapter>>

MQTT<<Application>>

‘Track my Tools’

AMQP 1.0AMQP 1.0MQTT

Eclipse Kapua

Eclipse Keti (proposed)

Ability to maintain access-decision data as policies and attributes

Exclusive security for multiple clients using the service (ACS services are tenant-aware)

Support for fine-grained authorization policies
