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…

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…
Developing a cloud-native web application for case-based file sharing on AWS
Motivation Professional file sharing is a significant challenge in sectors such as healthcare, insurance, and consulting. Practitioners routinely need to exchange sensitive documents with clients, yet existing solutions such as Google Drive and OneDrive can quickly become disorganized when managing multiple cases. Users struggle with scattered links, having to manually control access for each recipient…
