The Eclipse IoT project is a top level project at the Eclipse Foundation. It currently consists of around 40 projects, which focus on different aspects of IoT. This may either be complete solutions, like the Eclipse SmartHome project, the PLC runtime and IDE, Eclipse 4DIAC. Or it may be building block projects, like the MQTT libraries of Eclipse Paho, or the cloud scale IoT messaging infrastructure of Eclipse Hono. I can only encourage you to have a look at the list of projects and do a bit of exploring.

And while it is great to a have a diverse set of projects, covering the three tiers of IoT (Device, Gateway and Cloud), it can be a challenge to explain people, how all of those projects can create something, which is bigger than the individual projects. Because having 40 different IoT projects is great, but imagine the possibilities of having a whole IoT ecosystem of projects. Mixing and matching, building your IoT solution as you see fit.

When you want to secure a Spring Boot application with e.g. Let’s Encrypt or the OpenShift Service CA, then you will pretty soon figure out that working with PKCS #1 PEM files is a nightmare when it comes to Java. When you Google for PKCS #1 and Java, you will find all kinds of tutorials which suggest to use openssl and keytool to create a JKS or PKCS #12 keystore. As Java actually supports pluggable KeyStore implementations, I think there is a better solution for that.

In part #1 and part #2, we saw how easy it is to interface Apache Camel with Kura Wires. Simply by re-using some existing functionality. A few lines of XML, Groovy and you can already build an IoT solution based on the Camel ecosystem and the Eclipse Kura runtime. This part will focus on the Java DSL of Apache Camel.

Part #1 of the Apache Camel to Kura Wires integration tutorial did focus on pushing data from Kura Wires to Camel and processing it there. But part #1 already mentioned that it is also possible to pull in data from Camel into Kura Wires.

With the upcoming version of Eclipse Kura 4, we will see some nice new features for the embedded Apache Camel runtime. This tutorial walks you through the Camel integration of Kura wires, which allows you to bridge both technologies, and leverage the power of Apache Camel for your solutions on the IoT gateway.
