Case Study: Norwegian Labor and Welfare Administration (Nav) scales logging and boosts developer productivity with Aiven OpenSearch, Kafka, and Valkey

Norwegian Labor and Welfare Administration cuts log disruptions to zero and scales 400 GB daily with Aiven

The Norwegian Labor and Welfare Administration (Nav) faced challenges with its on-premises Elasticsearch logging infrastructure, which was costly to operate and required significant expertise to maintain. This system was critical for verifying the accuracy of welfare payments but struggled with performance under the scale of 4,000 weekly production changes. Nav turned to vendor Aiven to migrate this workload to Aiven for OpenSearch.

Aiven implemented a managed OpenSearch solution that integrated seamlessly with Nav's existing Aiven for Apache Kafka. The migration was completed in four months with no production disruptions. The results eliminated operational toil for engineers, freed them to focus on optimization, and provided a scalable, usage-based cost structure. Nav now reliably processes 400 GB of logs daily with zero production issues since the migration.
