Banking on Reliability: Cloud Native SRE Practices in Financial Services - Clément Nussbaumer

This talk by Clément Nussbaumer from PostFinance explores real-world experiences gained over five years of operating a Kubernetes platform in a major Swiss bank. The session highlights the impact of Service Level Objectives (SLOs) on improving systems such as API server load-balancing, nginx readiness probes, and etcd leadership transitions. Nussbaumer also presents two open-source Golang monitoring tools, detailing how community contributions enhanced their efficiency, and discusses a comprehensive end-to-end Golang test suite that addresses various platform challenges. The session concludes with an interactive debugging demonstration aimed at identifying the causes of infrequent 502 errors, a critical issue in the financial sector where transaction failures can have significant consequences.
