Agenda

6:00 PM	Networking and Food
6:30 PM	Introduction Talk
6:35 PM	Scaling Prometheus at Trade Republic: The Hard Way	At Trade Republic, rapid company growth is pushing our current Prometheus deployment – a single instance per environment deployed in a high-availability setup – to its limits. In this talk, I'll share the practical challenges, common pitfalls, and key lessons learned as we prepare to scale Prometheus at the collection layer. We'll explore Prometheus's internal constraints, such as resource consumption driven by cardinality and active time series, and discuss our current sharding strategies. Our approaches have their pros and cons but fit well into our use case – though they're not silver bullets for every scenario.
7:00 PM	Break
7:15 PM	kubezonnet: Monitor Cross-Zone Network Traffic in Kubernetes	Kubezonnet, an eBPF and Prometheus tool that reveals cross-zone (Kubernetes) network traffic. This talk covers its architecture and practical use cases for optimizing cost. We will briefly look at how we improved our Thanos setup by cutting costs across zones.
