If the COVID-19 epidemic taught us one lesson, then it is how dependent we are on data exchange over the internet. Just think back to yourself, how did you pass by 2020/2021? How did you exchange data with service providers or your employer? How did you entertain yourself while being under lock down or how […]
We are living in an area of digital transformation for many years now, driven by a continuously increasing pace of innovation and new disruptive business models. The speed to bring a new business idea as a digital service to the market is one of the key success factors, but it’s worth nothing when you are […]
Photo by Rene Böhmer on Unsplash By using Quarkus you can write lightweight and lightning-fast Java applications that scale on OpenShift/Kubernetes in a matter of milliseconds. But to achieve linear scalability and resilience of your application you should strive to create stateless applications. If you scale up multiple application instances that all connect to the […]
Part 1/4 discusses basic development principles with Kubernetes and gets deeper into Kustomize and OpenShift Templates.
It is still about you:
We want to expand our view from the discussed question in Part I on:
How you can ensure that you establish a good, long term strategy for your business
to:
how to build a solid foundation that matches your individual business model, providing just the right level of standardisation & Freedom in implementing business processes and IT.
Now, In part II We’ll Extend and finalise the framework, that intends to help you how a Business-IT Platform could look like with focus to to adjust your individual investments in that area to the optimal level.
Traditionally application development and deployment across environments has been very tedious and error prone. For example in the Java world you would work with different packaging formats such as ears, wars and jars each with environment specific configuration usually dispersed all over the place. Then your app might behave differently on each operating system due […]
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. […]
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 : […]
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 […]
OpenShift 3.3 and later contain the functionality to route pod traffic to the external world via a well-defined IP address. This is useful for example if your external services are protected using a firewall and you do not want to open the firewall to all cluster nodes. The way it works is that a egress […]
