At the recent EclipseCon Europe in Ludwigsburg, Germany, we had a big dashboard in the IoT playground area showing graphs of the number of WiFi devices, the temperature, and air quality, all transmitted via LoRaWAN. We worked on this project during the community day and kept the setup throughout the conference, where we showed it and played with it even further. This article describes the architecture of the setup and gives pointers to replicate it.

The Coderland booth at the recent Red Hat Summit was all about serverless computing as implemented in the Compile Driver. If you haven’t gone through that example (you really should), that code creates a souvenir photo by superimposing the Coderland logo, a date stamp, and a message on top of an image from a webcam. We thought it would be fun to build a Raspberry Pi version for the booth so we could offer attendees a free souvenir. Here’s a look at the finished product:

Red Hat AMQ Online 1.1 was recently announced, and I am excited about it because it contains a tech preview of our Internet of Things (IoT) support. AMQ Online is the “messaging as service solution” from Red Hat AMQ. Leveraging the work we did on Eclipse Hono allows us to integrate a scalable, cloud-native IoT personality into this general-purpose messaging layer. And the whole reason why you need an IoT messaging layer is so you can focus on connecting your cloud-side application with the millions of devices that you have out there.

In the first part of this series, we saw how effective a platform as a service (PaaS) such as Red Hat OpenShift is for developing IoT edge applications and distributing them to remote sites, thanks to containers and Red Hat Ansible Automation technologies.
Usually, we think about IoT applications as something specially designed for low power devices with limited capabilities. IoT devices might use a different CPU architectures or platform. For this reason, we tend to use completely different technologies for IoT application development than for services that run in a data center.
In part two, we explore some techniques that allow you to build and test contains for alternate architectures such as ARM64 on an x86_64 host. The goal we are working towards is to enable you to use the same language, framework, and development tools for code that runs in your datacenter or all the way out to IoT edge devices. In this article, I’ll show building and running an AArch64 container image on an x86_64 host and then building an RPI3 image to run it on physical hardware using Fedora and Podman.

Usually, we think about IoT applications as something very special made for low power devices that have limited capabilities. For this reason, we tend to use completely different technologies for IoT application development than the technology we use for creating a datacenter’s services.
This article is part 1 of a two-part series. In it, we’ll explore some techniques that may give you a chance to use containers as a medium for application builds—techniques that enable the portability of containers across different environments. Through these techniques, you may be able to use the same language, framework, or tool used in your datacenter straight to the “edge,” even with different CPU architectures!
We usually use “edge” to refer to the geographic distribution of computing nodes in a network of IoT devices that are at the “edge” of an enterprise. The “edge” could be a remote datacenter or maybe multiple geo-distributed factories, ships, oil plants, and so on.

If you haven’t heard about the RISC-V (pronounced “risk five”) processor, it’s an open-source (open-hardware, open-design) processor core created by the University of Berkeley. It exists in 32-bit, 64-bit, and 128-bit variants, although only 32- and 64-bit designs exist in practice. The news is full of stories about major hardware manufacturers (Western Digital, NVidia) looking at or choosing RISC-V cores for their product.

We are excited to announce a Developer Preview of Red Hat AMQ Streams, a new addition to Red Hat AMQ, focused on running Apache Kafka on OpenShift.
Apache Kafka is a leading real-time, distributed messaging platform for building data pipelines and streaming applications.
Using Kafka, applications can:
- Publish and subscribe to streams of records.
- Store streams of records.
- Process records as they occur.

We are seeking input from Internet of Things (#IoT) developers to better understand their needs for software and related tools. Whether you’re a hacker instrumenting your home with Raspberry Pi, or an IT developer working on Industrial IoT solutions, we want to know how you’re using open source technologies to build your IoT solution. The output from this survey will help the open source community focus on the resources most needed by IoT developers.

Arm TechCon 2017 – Embedded, IoT, Networking and no Server focus
Last month was Arm TechCon, the annual developer conference showcasing offerings from Arm and its partners. Arm laid out its vision and strategy to achieving even greater integration in its processors and circumventing the slowing Moore’s law. As always, there was a bevy of new product announcements but overall, the show seemed to lack the energy of the last few years and especially the excitement of last year after Arm was acquired by Softbank. For example, there was no big vision keynote like the one last year from Masayoshi Son (Chairman & CEO of Softbank) who had talked of IoT enabling a Cambrian Explosion (which enabled thousands of new species on Earth), leading to 1 trillion IoT devices in 20 years.
