OpenSearchCon Europe 2025

This talk will explore how OpenSearch can be leveraged to build a centralized and multi-tenant log analysis platform that provides logging-as-a-service to several Kubernetes enterprise environments.

We’ll address solutions for critical topics like cluster and tenant separation strategies, Kubernetes integration, automation, capacity management and monitoring best practices. Additionally, we’ll present our approach to non-technical challenges such as handling diverse tenant requirements, effective customer support and different areas of tenant collaboration.

Throughout the talk, there will be a strong emphasis on standardization as the primary solution component to achieve heterogeneity within the different configuration domains (retention policies, RBAC, etc.), while simultaneously maintaining the flexibility to be able adapt to customers' needs.

Drawing experience from a recent real-world implementation, this session will provide attendees with actionable insights and our lessons learned to overcome technical and operational challenges in building multi-tenant logging platforms using OpenSearch.
