Open source IoT gateway
4 likes3,693 views
This document summarizes a presentation about open source IoT solutions using Eclipse Kura and Apache Camel. It discusses the architecture of IoT systems using messaging, describes how Kura provides an OSGi-based gateway for connecting devices, and how Camel can be used within Kura for message routing and integration with backends. Examples are given of how Camel routes could be used in Kura to integrate devices and send data to backends.

Open source IoT gateway
- 1. Brought to you by Henryk Konsek Open source IoT gateway A tale of Eclipse Kura and Apache Camel
- 2. Henryk Konsek - engineer at Red Hat - open source junkie @hekonsek
- 3. Open Source IoT gateway (and surroundings) This talk @hekonsek
- 4. ● Architecture ● Messaging ● Gateway ● Backend This talk @hekonsek
- 6. IoT is messaging General concept @hekonsek
- 10. IoT solutions should rely on scalable messaging (aka MaaS). Scalable IoT messaging ● AMQP-centric ● Based on Qpid Dispatch Router ● Artemis used for store & forward ● IoT-scale ready @hekonsek
- 11. Non-AMQP protocols are translated to AMQP before hitting backend. Protocol adapters @hekonsek
- 12. Kafka for IoT telemetry @hekonsek
- 13. We are working together with Bosch (et al.) on Eclipse Hono project. Eclipse Hono @hekonsek
- 14. Hono is a narrow subset of our end-to-end IoT architecture. What is Hono? ● Hono follows our IoT architecture ● Provides a narrow subset of operations on the top of our middleware (telemetry and command/control) ● Provides backend implementation of those operations ● Will be based on Qpid dispatch @hekonsek
- 16. Gateway TL;DR; A proxy between field devices and a data center GATEWAY @hekonsek
- 17. OSGi-based IoT gateway for field devices. Eclipse Kura @hekonsek
- 18. Kura services OSGi Application Container (Eclipse Equinox, Concierge) Java SE 7 / 8 (OpenJDK) Serial GPIO HID BLE I2C Field protocols Networking Gateway Services Web UI Remote Management Cloud Services Data Services EP Connectivity and Delivery @hekonsek
- 19. Eclipse. Donated by Eurotech (http://eurotech.com). Who’s behind Kura? @hekonsek
- 20. Red Hat and EuroTech are partners now. Red Hat + EuroTech @hekonsek
- 21. Kura + Camel (aka ESF + Fuse) . Running on EuroTech hardware with RHEL. Our first baby! @hekonsek
- 22. A message routing framework. What is Apache Camel? @hekonsek
- 23. How to orchestrate messages flow. What is message routing? ● Apache Camel ● Spring Integration ● Mule @hekonsek
- 24. - 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
- 25. Camel provides ~200 OSGi-ready connectors (JMS, REST, CoAP, AMQP, MQTT…) How can Kura benefit from Camel? @hekonsek
- 26. Enterprise Integration Patterns (EIP) How can Kura benefit from Camel? @hekonsek
- 27. Prevents messages overflow. EIP - throttler @hekonsek
- 28. Dynamically decide where to route the message. EIP - content based router @hekonsek
- 29. Client side load balancing. Useful for field devices connectivity. EIP - load balancer @hekonsek
- 30. How can I control which parts of a field device should be running at the given moment? EIP - control bus @hekonsek
- 31. Camel OSGi bundle is started from the Kura. Kura + Camel: architecture @hekonsek
- 32. Capture images from Raspberry Pi camera and send to backend for analysis. Camel route module for Kura public class MyKuraRouter extends CamelRouter { @Override public void configure() throws Exception { from("webcam:plates"). to("netty4-http:http://app.mydatacenter.com/plates/upload"); } } @hekonsek
- 33. Display WiFi networks accessible near the field device using the web browser. More examples 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
- 34. Start syncing cached data only when WiFi is accessible. More more examples 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:http://api.mydatacenter.com/showMeWiFi"); } } @hekonsek
- 35. Loading XML Camel routes at runtime using web UI. Routes management @hekonsek
- 36. Camel is a 1st class citizen in Kura. Camel as a core part of the Kura @hekonsek
- 37. Kura - what’s next? ● Drools (BRMS) integration ● More Camel components (BLE, modbus, etc.) ● Integration with external processes (including Docker running on gateway) @hekonsek
- 39. There are many open source components out there. So you can assemble your IoT platform by yourself. What we currently have @hekonsek
- 40. We are working with EuroTech on open sourcing their IoT backend platform (aka Eclipse Kapua project). What we wanna have @hekonsek
- 41. Everyware Cloud is based on Fuse A-MQ already. And is Kubernetes friendly. Good starting point @hekonsek
- 42. Kura + Kapua + Hono + Red Hat open source software. Delivered by Red Hat + EuroTech dream team :) . Our ultimate goal @hekonsek
- 43. Thank you!
