Die Konferenz widmet sich Themen rund um den gesamten Software-Lifecycle – von Infrastruktur und Cloud-Architektur über Dev(Sec)Ops und CI/CD bis hin zu Platform Engineering und Agentic AI. Das zweitägige Programm bietet praxisorientierte Fachvorträge, Erfahrungsberichte sowie Möglichkeiten zum fachlichen Austausch.
Wir freuen uns sehr, dass unsere Kollegen Christian Rohmann und Timon Engelke mit ihrem Vortrag Seeing the Unseen: Uncovering Invisible Traffic on Kubernetes with eBPF vertreten sein werden.
Abstract:
In large Kubernetes clusters, network traffic quickly becomes complex, yet for most teams, the network flows remain completely hidden. Because modern cloud bandwidth is vast, this invisible traffic is rarely scrutinized. But unchecked traffic can lead to high cloud bills and often serves as a silent indicator of underlying inefficiencies.
In this presentation, we demonstrate how leveraging OpenTelemetry eBPF instrumentation (OBI) helped us uncover and mitigate massive traffic flows – particularly expensive cross-zone traffic – in a production environment. We share our findings and concrete examples of how we were able to drastically reduce this traffic.
