Von der lokalen Chat-App zur Cloud
Ausgangspunkt und Tech-Stack Unsere Chat-Anwendung entstand ursprünglich als lokales Projekt. Für das Cloud-Computing-Projekt wollten wir deshalb nicht die Anwendung neu entwickeln, sondern herausfinden, wie sie sich in der Cloud betreiben lässt. Die Anwendung besteht aus einem React-Frontend mit Vite und einem FastAPI-Backend. WebSockets ermöglichen die Echtzeitkommunikation. MongoDB speichert die Nachrichten, Redis verteilt Ereignisse zwischen mehreren…

GitOps for a Greenhouse That Grows in the Cloud
A minimal GitOps reconciler for a simulated greenhouse edge device. Live Demo Introduction As software developers we’re kind of trained to expect that anything that can go wrong eventually will, so we build fallbacks, write tests, and generally design around failure. I spend a lot of my time automating devices that are annoyingly far from…
Leased cloud machines: making a teardown guarantee observable
Renting a cloud machine is a single API call. Giving it back reliably took four months. This post follows horizon through three rewrites, the teardown layers that survived them, and the measurements that show whether the guarantee actually holds.

Reliable Payment Processing in Ultra-Large-Scale Systems: A Case Study of a Ride-Hailing Platform
Moving money correctly is one of the hardest problems that an Ultra-Large-Scale System (ULSS) must solve. At a volume of billions of transactions, even a vanishingly small error rate translates into substantial financial loss, regulatory exposure, and reputational damage. This paper examines the architecture of a large-scale payment platform using a ride-hailing service as a…

Building a Modern C Project: Zig, WebAssembly, and Visual CI/CD
How we used Zig as a build system, Emscripten for the web, and Python for automated visual regression testing on a C-based path tracer. 1. Introduction Writing a path tracer from scratch in C is a fantastic way to learn the physics of light simulation. But maintaining that project, ensuring it builds across platforms, catching…
Tools zur automatischen Erstellung von SBOMs
Transparenz und Sicherheit durch automatisierte Software-Stücklisten Anmerkung: Dieser Blogpost wurde während dem Sommersemester 2025 für das Modul Enterprise IT (113601a) verfasst. 1. Einleitung Moderne Software besteht längst nicht mehr nur aus eigenem Quellcode. In nahezu jedem Projekt werden große Mengen externer Bibliotheken, Frameworks und Open-Source-Komponenten genutzt. Wie auch bei physischen Lieferketten sind jedoch auch die einzelnen…
GitOps Demystified: Principles, Practices, and Challenges
GitOps, a term coined by Alexis Richardson (CEO of Weaveworks) in 2017, represents a modern approach to continuous deployment and infrastructure management that leverages Git as its core technological foundation [1]. At its essence, GitOps extends the familiar Git workflow patterns from application development to infrastructure management, establishing Git repositories as the single source of…

In our Software Development for Cloud Computing course, we were tasked with building something, anything, using the cloud. After various discarded ideas, our team decided to create a platform aimed at automatically generating short-form videos. In this blog post, we will go over our development journey, the architectural decisions we made, the technologies we chose…
