Eclipse Hono - Remote service interfaces for connecting large numbers of IoT devices

Eclipse Hono provides uniform (remote) service interfaces for connecting large numbers of IoT devices to a (cloud) back end. It specifically supports scalable and secure data ingestion (telemetry data) as well as command & control type message exchange patterns and provides interfaces for provisioning & managing device identity and access control rules.

It can connect millions of devices, Its micro service based architecture and use of a reactive programming model allow for scaling out horizontally. It provides APIs for important IoT communication patterns: Telemetry and Event messages can be used by devices to report sensor readings whereas applications can use Command & Control to invoke operations on devices.
