The OTel spec and Collector, W3C Trace Context and B3 Propagation, OSS backends like Jaeger/Tempo/Zipkin, the observability 2.0 camp (Honeycomb, SigNoz), APM giants (Lightstep, Datadog, New Relic, Dynatrace), eBPF auto-instrumentation (Pixie, Beyla) — where to pick what, how to tame head vs tail sampling and cost, and how Korean and Japanese companies actually migrated.

OTel 사양과 Collector, W3C Trace Context와 B3 Propagation, Jaeger/Tempo/Zipkin 같은 OSS 백엔드, Honeycomb과 SigNoz 같은 observability 2.0 진영, Lightstep과 Datadog/New Relic/Dynatrace 같은 APM 거인, 그리고 Pixie/Beyla로 대표되는 eBPF 자동 계측까지 — 어디서 무엇을 골라야 하는지, 헤드/테일 샘플링과 비용은 어떻게 다스리는지, 한국과 일본 기업들이 어떻게 마이그레이션했는지까지 심층 비교.
