IoT = Data Center + Embedded
IoT consolidates data center and embedded worlds.
The datacenter systems are located in a data center.
Datacenter systems in a nutshell
IoT architecture is a superset of a datacenter architecture.
IoT architecture
Synchronous communication, usually via HTTP.
Communication in the datacenter systems
The “IoT fun” part!
Communication in the IoT systems
Eclipse Kura
OSGi-based IoT gateway for field devices.
What is Eclipse Kura?
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)
What is Eclipse Kura?IoT gateway● collects messages from the edge devices (like sensors)● performs messages processing/aggregation/forwarding

Who’s behind Kura?
Apache Camel
The message routing framework.
What is Apache Camel?
How to orchestrate messages flow.
What is message routing?
● Apache Camel● Spring Integration● Mule
- 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')]
Why Camel and Kura?
Camel provides ~200 OSGi-ready connectors (JMS, REST, CoAP, AMQP, MQTT…)
How can Kura benefit from Camel?
Enterprise Integration Patterns (EIP)
How can Kura benefit from Camel?
Prevents messages overflow.
EIP - throttler
Provides SLA for the different channels.
EIP - throttler
Dynamically decide where to route the message.
EIP - content based router
Client side load balancing. Useful for field devices connectivity.
EIP - load balancer
How can gateway provide transaction-like behavior when connecting to a non-transactional service?
EIP - idempotent consumer
How can I control which parts of the field device should be running at the given moment?
EIP - control bus
How Camel and Kura?
Camel OSGi bundle is started from the Kura.
Kura + Camel: architecture
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"); } }
Just deploy the route as the OSGi bundle and enjoy Camel running the Kura.
Concerned about the lifecycle?
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"); } }
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"); } }
