Serverless architectures often trade infrastructure management for operational complexity. When your "search" is a black box and your "compute" is ephemeral, how do you debug a high-latency query or a failing ingestion pipeline? In this session, we’ll dive into a production-ready blueprint using Amazon OpenSearch Serverless and AWS Lambda. We will walk through instrumenting these services using OpenTelemetry (OTel)—without manual boilerplate—and how to use New Relic as your central brain for correlating traces, metrics, and logs across the entire serverless lifecycle.
