## AI overview

The article describes how a platform team moved from team-managed observability to self-service observability for more than 90 internal teams. It explains the use of OpenTelemetry in a NestJS-based Platform SDK to provide consistent telemetry semantics, cost guardrails, and vendor-neutral export, with a reported 4x TPS improvement.

## Source excerpt

Discover how one platform team shifted from "teams doing observability" to self-service observability by embedding OpenTelemetry into a NestJS Platform SDK. Learn the four pillars of their policy approach to achieve consistency, cost guardrails, and scale for 90+ internal teams, leading to a 4x TPS improvement
