Editorial take
Why it stands out
Pair with Tempo, Jaeger, or vendor APM for trace storage; compare OpenTracing legacy stacks migrating forward.

Tool profile
CNCF standard for traces, metrics, and logs: vendor-neutral SDKs, collectors, and semantic conventions so telemetry exports to any backend.
Microservices needing consistent trace context propagation
OpenTelemetry is how modern apps avoid vendor lock-in at the instrumentation layer: auto-instrument popular frameworks, configure OTLP exporters, and route through the Collector for tail sampling or PII scrubbing. It is not a storage or UI product—you still pick Grafana, Datadog, Honeycomb, or others for backends. Investment pays off when you rebalance vendors without rewriting every span.
