Eclipse Kura
@hekonsek
OSGi-based IoT gateway for field devices.
What is Eclipse Kura?@hekonsek
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)
@hekonsek
What is Eclipse Kura?IoT gateway● collects messages from the edge devices (like sensors)● performs messages processing/aggregation/forwarding
OSGi-based IoT gateway for the field devices.

What is Eclipse Kura?
OSGi-based IoT gateway for the field devices.
@hekonsek
Gateway TL;DR;
A proxy between field devices and a data center
GATEWAY
@hekonsek
Eclipse. Donated by Eurotech (http://eurotech.com).
Who’s behind Kura?@hekonsek
Apache Camel
@hekonsek
A message routing framework.
What is Apache Camel?@hekonsek
How to orchestrate messages flow.
What is message routing?
● Apache Camel● Spring Integration● Mule
@hekonsek
- 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')]
@hekonsek
Why Camel and Kura?
@hekonsek
Camel provides ~200 OSGi-ready connectors (JMS, REST, CoAP, AMQP, MQTT…)
How can Kura benefit from Camel?@hekonsek
Enterprise Integration Patterns (EIP)
How can Kura benefit from Camel?@hekonsek
Prevents messages overflow.
EIP - throttler@hekonsek
Provides SLA for the different channels.
EIP - throttler@hekonsek
Dynamically decide where to route the message.
EIP - content based router@hekonsek
Client side load balancing. Useful for field devices connectivity.
EIP - load balancer@hekonsek
How can I control which parts of a field device should be running at the given moment?
EIP - control bus@hekonsek
How Camel and Kura?
@hekonsek
Camel OSGi bundle is started from the Kura.
Kura + Camel: architecture@hekonsek
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"); } }
@hekonsek
Just deploy the route as the OSGi bundle and enjoy Camel running the Kura.
Concerned about the lifecycle?@hekonsek
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"); } }
@hekonsek
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"); } }
@hekonsek
Loading XML Camel routes at runtime using web UI.
Routes management@hekonsek
Camel will be soon a 1st class citizen in Kura.
Camel as a core part of the Kura@hekonsek
http://rhiot.io
Rhiot@hekonsek
Soon to be converted to Maven archetype :) .
Rhiot Kura quickstarts@hekonsek
git clone [email protected]:rhiot/quickstarts.git
cp -r quickstarts/kura-camel kura-camel
cd kura-camel
mvn install
CloudService user doesn’t know that payload is dispatched to Camel.
Rhiot CamelCloudService@hekonsek
CloudService cloudService = new DefaultCamelCloudService();CloudClient client = cloudService.newCloudClient("appId");
// Publish message to internal in-memory Camel queuecloudClient.publish("topic", "foo".getBytes(), 0, true, 0);
// Read message from Camel routefrom("kura-cloud:appId/topic"). to("netty4-http:http://example.com");
Use CloudService to publish message to any endpoint supported by Camel.
Rhiot CamelCloudService@hekonsek
CloudService cloudService = new DefaultCamelCloudService();CloudClient client = cloudService.newCloudClient("appId");
cloudClient.publish("amqp:topic", "foo".getBytes(), 0, true, 0);
