Scaling Welfare With Open Source: How NAV Migrated To Managed OpenSearch - Dmitry Kan, Aiven & Hans Kristian Flaatten, Norwegian Government

Friday April 17, 2026 14:25 - 15:05 CEST

Bohemia 2

The Norwegian Labor and Welfare Administration (NAV) manages 1/3 of Norway’s state budget. Supporting their "product-first" paradigm for 20,000 employees required a shift from legacy monoliths to a centralized, self-service observability stack. NAV partnered with Aiven to migrate their logging infrastructure to a managed OpenSearch environment. Aiven has been a strategic partner of NAV by hosting some of NAV’s most critical data services for many years. As a founding member of the OpenSearch Foundation with active maintainers, Aiven provided a unique advantage in helping NAV adopt OpenSearch for their application logging.
This technical deep-dive covers:
* Migration Architecture: High-throughput logging from on-premise to a managed service with zero-downtime
* Scalability & Performance: Shard rebalancing, customized scaling, and automated snapshots
* Data Pipeline: 60TB of log data, and OpenTelemetry traces with Data Prepper
* Operational Stability: Self-healing nodes and alert integrations with Slack.
We will cover usage scenarios of OpenSearch dashboards and take a close look at how Aiven delivers and operates OpenSearch as a managed service at Nav’s scale.
