Getting value from IoT, Integration and Data Analytics
Applications nowadays, are usually deployed inside containers. A container consists of libraries and tools which allow the application to run inside. Since there can be exploitable vulnerabilities, it is not only important to take security into account for your application, but also for the container it runs in. There are […]

0 0 As a developer I wanted to experiment with Kubernetes environments which approximate production deployments. In order to do that I wanted a distributed storage solution and chose OpenEBS. Mainly because it was easy to get started and quick to get up and running. In this blog post I’ll describe how […]
0 0 Coming to this solution was a journey. I was looking for a Kubernetes installation which was easy to deploy and cleanup on my own laptop (I didn’t want to have to pay for a hosted solution). I did want a solution which was more or less production-like because I wanted […]
0 0 In the previous article I explained how to set up multiple environments for Azure Pipelines. In this article I will explain how you can deploy the artifacts to the on-premise VM’s. This are the artifacts you build in the pipeline. I am using an template for this, because we are […]

Not only can it deploy to the azure cloud, it can also deploy to self hosted VMs. Even multiple, with multiple stages. For instance, an Acceptance, Test and Production environment. All of this […]
0 0 When running Java applications in containers, you need to be careful with your resources. If you’re not careful with layering your images (for example using Google’s Jib), you can quickly get into disk-space issues, especially when your base image and/or application gets updated regularly. One of the ways you can save […]
0 0 Resources in Oracle Cloud Infrastructure can be managed through the console – the browser based UI. That works great but requires manual steps – no automation – that take time and easily go wrong (and become extremely boring over time). Additionally, it is a rather individualistic way of working that […]
0 0 Terraform is a platform for implementing Infrastructure as Code. Terraform defines a syntax for describing resources and provides an engine that interprets the resources definitions, compares this desired state with the existing state in the destination environment and subsequently attempts to bring the destination in line with the desired state.
