Designing the framework for a scalable CI/CD supported web application
Documentation of our approaches to the project, our experiences and finally the lessons we learned. The development team approaches the project with little knowledge of cloud services and infrastructure. Furthermore, no one has significant experience with containers and/or containerized applications. However, the team is well experienced in web development and has good knowledge of technologies…

Entwicklung und Benchmarking einer eigenen Elevation API
Worum geht’s? Im Rahmen der Veranstaltung “System Engineering and Management” sollte ein Softwareprojekt unserer Wahl und mit besonderem Augenmerk auf Systemarchitektur durchgeführt, analysiert und dokumentiert werden. Für unser Projekt haben wir uns entschieden, einen besonderen Schwerpunkt auf Monitoring zu legen. Das Projekt bestand also aus drei größeren Teilprojekten: dem Backend selbst, ein Stresser, der Last…
KISS, DRY ‘n SOLID — Yet another Kubernetes System built with Ansible and observed with Metrics Server on arm64
This blog post shows how a plain Kubernetes cluster is automatically created and configured on three arm64 devices using an orchestration tool called Ansible. The main focus relies on Ansible; other components that set up and configure the cluster are Docker, Kubernetes, Helm, NGINX, Metrics Server and Kubernetes Dashboard. Individual steps are covered more or…
Effiziente Last-Abarbeitung
Geschrieben von Steffen Köhler und Laurin Keim. Einleitung Bei dem vorliegenden Block-Post handelt es sich um den Zusammenschrieb eines Studentenprojekts mit dem Motto “Last effizient abarbeiten”. In diesem wurden verschiedene Vorgehensweisen, Protokolle und in gewissem Maße auch Hardware-Architekturen erarbeitet und nachvollzogen. Dabei wurden teilweise eigene Vorgehensweisen erdacht und anschließend mit bereits bestehenden Protokollen verglichen. Während…
Industry 4.0 – Real time data visualization
As part of the lecture “System Engineering and Management”, we worked on a project in cooperation with IBM to visualize Industry 4.0 data in real time using a configuration-based approach. This project aims to avoid needing a web developer every time there is a modification in the data.
Migrating from Heroku to Hetzner: Achieving Scalability with Docker, Kubernetes and Rancher
Dockerizing an existing application and deploying it in a Kubernetes Cluster via Rancher to achieve better scalability and cost minimization. Load Testing with Artillery, Monitoring with Prometheus & Grafana and GitHub Actions for CI/CD were used in the process.
System Theory and an Introduction to Complexity
This article gives an introduction to some important aspects of system theory and system analysis. We present some frameworks and toolsets used for system analysis and summarize some key points of these tools. The article aims to show some of the complexity behind system analysis and why there often is no simple solution. It then…
Open Source Batch and Stream Processing: Realtime Analysis of Big Data
Abstract Since the beginning of Big Data, batch processing was the most popular choice for processing large amounts of generated data. These existing processing technologies are not suitable to process the large amount of data we face today. Research works developed a variety of technologies that focus on stream processing. Stream processing technologies bring significant…
Autoscaling of Docker Containers in Google Kubernetes Engine
In this blog post we are taking a look at scaling possibilities within Kubernetes in a cloud environment. We are going to present and discuss various options that all have the same target: increase the availability of a service.
