Today more than ever availability and performance depend on resilience against increasingly frequent and powerful attacks on the confidentiality, availability and integrity of information and IT systems. It is not just that our systems are being threatened with continuous automated attacks, but also with highly sophisticated approaches, such as Advanced Persistent Threats (APTs), Ransomware, Side […]
Our experiences preparing for a demo at Ansiblefest 2021 Speakers: Karoly “Charlie” Vegh and Robert “Bob” BaumgartnerSupported by: Chris Jung, Phil Griffith, Eric Lavarde, Elle Lathram Introduction and Purpose AnsibleFest is always pretty cool, all new announcements, live demos, roundtable discussions, etc. Bob, being the Kubernetes/Container Architect and my humble self being more a Linux […]
Finally, the time has come. The first personal event after Corona. The Container Days 2021 were just around the corner. Right on time for the start of the event, the location presented itself from its best side. It was rainy. At the latest now it was clear: I’m in the north of Germany, on the […]
Introduction In this article series we are going to build together a sample cloud-native IoT architecture, called Bobbycar, based on the Red Hat OpenShift Container platform and a lot of other relevant technologies. The first part of the series should provide you with the necessary background on IoT-, Edge- and Cloud Computing and also briefly […]
Docker came a long way. It established itself very fast as the de-facto standard to get going with your container journey. It did not matter if you wanted to just play around with containers or if you wanted to build up new microservices, Docker was and still is a great choice to get yourself started. […]
It is 2020 and everybody is talking more and more about containers. A topic that came up around 2013 with Docker making an ecosystem for developers using containers for faster development cycles. But although the container hype is growing there are still lots of VMs out there, that may also have their right to exist. […]
In my last post I promised to introduce you to a selected set of Quarkus extensions. Today I will cover three of those. In my opinion they make total sense in the context of a container development or just container runtime platform (such as Red Hat OpenShift or any other Kubernetes distribution). The effort : […]
Many of us use container images from day to day, maybe also in many various architectures. For example on your Raspberry PI (aarch64), do you really know how it works in detail? I have worked with container images more or less since 2015 but during an OpenShift 4 air-gapped installation and mirroring of images into […]
Quarkus is the bright new star in the cloud-native App Dev universe! Quarkus is Red Hat’s upstream stack for Kubernetes native Java. Its characteristics are simple: Quarkus is small! Quarkus is fast! Quarkus is familiar! … and Quarkus makes Java relevant again in the cloud-native world where everyone talks about lightweight architectures, event-driven paradigms, container […]
If you have followed my earlier posts, then you know, that I’m in the process of building an IoT Demo, with a Raspberry Pi2 as the Smart Gateway. During this process, I had to re-install my Raspberry multiple times, but after the second time I got a bit tired of doing the same steps over […]
