ESP8266 and DHT22 based smart sensor

This is part 3 in my IoT series of blogs. The first parts did cover the following topics Introduction into the planned scenario Building a Rasperry Pi based Smart Gateway In this article I will describe how I build my first physical sensor, based on an ESP8266 microprocessor and a DHT22 digital temperature and humidity sensor. […]

Building a Raspberry Pi based Smart Gateway for IoT

As described in my previous post, my intention is to create a new version of my IoT Demo. The first element that I wanted to get up and running is the Gateway, which is supposed to run a MQTT broker to receive and forward messages a transformation capability to change messages, enable smart routing of […]

Red Hat IoT Demo – Next Generation

After having done a pure Docker/JBoss based IoT Demo-Environment I felt like it was time to bring this demo to the next level, but what does that mean? For me it means to become a bit more “realistic” and to integrate more and different technologies into the demo. In hard facts, this mean real, “dumb” […]

First Fuse application on OpenShift V3.1

Since mid of December 2015, Red Hat has released the initial version of the Fuse Integration Services. These are various pre-build images which are aimed to make the implementation of Red Hat JBoss Fuse applications on OpenShift V3 as seamless as possible. In this blog I will document the steps required to create a first […]

Pushing an external and not yet published Docker image into Red Hat OpenShift V3

If you should have followed my previous postings ( thanks for that!! ), then you should have read my blog IMPORTING AN EXTERNAL AND NOT YET PUBLISHED DOCKER IMAGE INTO RED HAT OPENSHIFT V3, in which I have explained how to manually carry a Docker image from a non OpenShift build-server to our OpenShift infrastructure. This […]

Securing the OpenShift V3 Registry

In my previous post I described how to manually export/import a Docker image from one system into the Docker registry of OpenShift. A next step would be to push an image from a non OpenShift system directly into the registry. The documentation of OpenShift recommends to secure the registry before opening it for external access. […]

Importing an external and not yet published Docker Image into Red Hat OpenShift V3

During many customer discussions on PaaS, the same question does come up: “Can I use my own Docker images in OpenShift?” While the simple answer obviously is: “Well, sure! OpenShift makes use of Docker und Kubernetes“ Making it work, is a little bit more complex – until one finally understands it. In this blog I […]

IaaS & PaaS, aren’t they the same? Part 2

Motivation This is a follow-up on my initial posting on IaaS vs PaaS. While part 1 was an introduction into what IaaS is and how PaaS differs, this posting will look into an exemplary business-case, comparing those two approaches. The scenario and the numbers used in this business-case will be simple, as this exercise is not […]

Internet of Things – A Red Hat JBoss Demo Setup

What it’s all about This demo is supposed to show a lab-based version of a typical Internet of Things ( IoT ) setup. It follows a 3-Layered architecture of Edge: as created of data Controller: first level of data processing Datacenter: well, the datacenter … These layers can – and in this demo will – […]

IaaS & PaaS, aren’t they the same? Part 1

During the last year of my customer meetings I have very often been addressed with the same scenario, which is comparing traditional ways of doing stuff ( also known as Mode 1 IT ) with more dynamic, up to date and cloud ready “Mode 2” approaches. To be more precise, I have had many discussions […]
