OpenSearchCon Europe 2026

Running OpenSearch in Kubernetes sounds simple — until you try to do it at scale, with high availability, zero downtime, and evolving workloads. In this talk, we draw on years of production experience operating OpenSearch clusters for SAP Cloud Logging service. We aim to share the key lessons learned and design patterns from building our Kubernetes operator.

We’ll dive into how we approached seamless upgrades, built tailored monitoring, and improved performance when interacting with OpenSearch APIs. Even if we adapt solutions to fit internal needs, the lessons learned are valuable for the broader OpenSearch and Kubernetes community.

In the second half, we turn our focus to the open-source OpenSearch Kubernetes Operator. We’ll explore its current state, the challenges the community is addressing and efforts to improve its reliability. We’ll also discuss how this open-source offering enables organizations to seamlessly scale and manage OpenSearch clusters on Kubernetes, and highlight opportunities for collaboration within the project.
