Using PKCS #1 PEM encoded X.509 certificates in Java
PEM is a well know file format when it comes to certificates. And when using Kubernetes (or OpenShift in my case) it is so easy to re-use the internal CA for some tasks.
Eclipse Kura on the Intel UP² with CentOS
In the past I was testing modifications to Kura with a Raspberry Pi 3 and Fedora for ARM. But I got a nice little Intel UP² just recently, and so I decided to perform my next Kura tests, with the modifications to the Apache Camel runtime in Kura, on this nice board. Creating a new device profile for Kura using CentOS 7 and the Intel UP² looked like a good idea anyway.
Build your own IoT cloud platform
If you want to do large scale IoT and build your own IoT cloud platform, then you will need a messaging layer which can actually handle this. Not only handle the sheer load of messages, the number of connections. Even more important may be ability to integrate your custom bits and pieces and be able to make changes to every layer of that installation, in a controlled, yet simple way.
CEP & Machine learning for IoT – Drools on Kura
Machine learning and predicate maintenance we are the role models of IoT use cases. Having an IoT gateway allows you to pre-process data before you send it upstream to your cloud. It also allows you to do local decisions, without the actual need for a cloud upload. But as you know from sitting at your favorite restaurant, staring at the menu, making decisions can be quite hard ;-) Complex event process and machine learning models can help you with IoT use cases though.
