This document discusses using Apache Camel with Eclipse Kura to build IoT gateways. It provides an overview of Eclipse Kura as an OSGi-based IoT gateway platform and Apache Camel as a message routing framework. It describes how Camel's connectors and integration patterns can benefit Kura by enabling communication with various protocols and providing features like throttling, load balancing, and idempotent consumption. Examples are given of Camel routes deployed on Kura that retrieve WiFi network data and sync cached data based on WiFi connectivity. The Rhiot project is also mentioned as a Kura+Camel router supported through a Eurotech partnership.

20. Eclipse Kura

21. OSGi-based IoT gateway for field devices.
What is Eclipse Kura?

22. OSGi-based IoT gateway for the field devices.
OSGi
● modularity system for Java
● provides modules classpath separation
● promotes hot runtime redeployments
What is Eclipse Kura?
OSGi Application Container (Eclipse Equinox, Concierge)
Java SE 7 / 8 (OpenJDK)

23. What is Eclipse Kura?
IoT gateway
● collects messages from the edge devices (like sensors)
● performs messages processing/aggregation/forwarding

Who’s behind Kura?

29. Apache Camel

30. The message routing framework.
What is Apache Camel?

31. How to orchestrate messages flow.
What is message routing?
● Apache Camel
● Spring Integration
● Mule

32. - read message from JMS queue
- transform to JSON
- save to FTP and MongoDB
Crash course to the Apache Camel
from('jms:invoices').
transform { new Invoice(uuid(), it.in.body) }.
marshal().json(Jackson).
multicast().parallelProcessing().
to('ftp:myftp.com/invoices',
'mongodb:myDb?collection=invoices&operation=save')
]

33. Why Camel and Kura?

34. Camel provides ~200 OSGi-ready connectors (JMS, REST, CoAP, AMQP,
MQTT…)
How can Kura benefit from Camel?

35. Enterprise Integration Patterns (EIP)
How can Kura benefit from Camel?

36. Prevents messages overflow.
EIP - throttler

37. Provides SLA for the different channels.
EIP - throttler

38. Dynamically decide where to route the message.
EIP - content based router

39. Client side load balancing. Useful for field devices connectivity.
EIP - load balancer

40. How can gateway provide transaction-like behavior
when connecting to a non-transactional service?
EIP - idempotent consumer

41. How can I control which parts of the field device
should be running at the given moment?
EIP - control bus

42. How Camel and Kura?

43. Camel OSGi bundle is started from the Kura.
Kura + Camel: architecture

44. Invoke REST method every second.
Camel route module for Kura
public class MyKuraRouter extends KuraRouter {
@Override
public void configure() throws Exception {
from("timer:trigger").
to("netty4-http:http://app.mydatacenter.com/api");
}
}

45. Just deploy the route as the OSGi bundle and enjoy Camel running the Kura.
Concerned about the lifecycle?

46. Display WiFi networks accessible near the field device using the web
browser.
Fancy example #1
public class MyKuraRouter extends KuraRouter {
@Override
public void configure() throws Exception {
from("netty4-http:http://0.0.0.0:18080").
to("bean:org.eclipse.kura.net.NetworkService?method=getAllWifiAccessPoints");
}
}

47. Start syncing cached data only when WiFi is accessible.
Fancy example #2
public class MyKuraRouter extends KuraRouter {
@Override
public void configure() throws Exception {
from("kura-wifi:wlan0/mySSID").
to("controlbus:route?routeId=onlineSync&action=start");
from("file:///var/sensor/temperature").
routeId("onlineSync").autoStartup(false).
to("netty4-http://api.mydatacenter.com");
}
}
