How Elasticsearch Powers Netflix's Search and Observe

Netflix runs one of the largest Elasticsearch deployments in the world — over 150 clusters, thousands of nodes, processing tens of billions of documents. In this episode, Lucas and Luna unpack how Netflix uses Elasticsearch not just for log aggregation, but to power its internal search, real-time monitoring, and even the titles you see when you open the app. They walk through the architecture behind Netflix's search — from how they handle partial matches across 17,000 titles to how they keep observability data flowing without crashing the clusters. Along the way, they cover shard sizing, index lifecycle management, and the painful lessons Netflix learned when Elasticsearch failed at scale. A practical episode for any engineering leader running search or observability at scale. #Elasticsearch #Netflix #SearchArchitecture #Observability #Logging #DistributedSystems #Sharding #IndexLifecycleManagement #RealTimeMonitoring #EngineeringLeadership #CTO #TechnicalDebt #Infrastructure #SiteReliabilityEngineering #BusinessAndTechnology #FexingoBusiness #BusinessPodcast #TheCTOPodcast Keep every episode free: buymeacoffee.com/fexingo
