Cloud Native Aachen Meetup, April 2026

Spring is finally around and we're celebrating with another two great talks!

Talks

Our first talk by Jeremy Theocharis, Co-Founder and CTO of United Manufacturing Hub, an open-source infrastructure platform for modern factories. Kubernetes was designed as a control system. The original designers said so in their 2016 "Borg, Omega, and Kubernetes" ACM paper. Control theory explains why Kubernetes recovers: the reconciliation architecture is control theory done right. But control theory has been predicting system failures for decades, and it predicts Kubernetes failures just as well. This talk walks through both sides, why it's resilient and where it breaks.

Our second talk by Holger Falk, Site Reliability Engineer at INFORM, operating an Enterprise-Scale Kubernetes Multi-Tenancy with Capsule. They manage a large-scale Kubernetes platform serving dozens of engineering teams using a lightweight multi-tenancy approach powered by Capsule. This talk demonstrates how Capsule provides namespace-as-a-service while seamlessly integrating with the CNCF ecosystem including FluxCD for GitOps, Crossplane for self-service infrastructure, and Kyverno for policy enforcement. We'll share our production architecture patterns, real-world challenges, and lessons learned from operating multi-tenant clusters at scale, showing how a simple, opinionated tenancy model enables developer autonomy while maintaining platform team control.
