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 … Read moreBuilding a Raspberry Pi based Smart Gateway for IoT

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” … Read moreRed Hat IoT Demo – Next Generation

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 … Read moreFirst Fuse application on OpenShift V3.1

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 … Read morePushing an external and not yet published Docker image into Red Hat OpenShift V3

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. … Read moreSecuring the OpenShift V3 Registry

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 … Read moreImporting an external and not yet published Docker Image into Red Hat OpenShift V3

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 … Read moreIaaS & PaaS, aren’t they the same? Part 2

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 – … Read moreInternet of Things – A Red Hat JBoss Demo Setup
