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.
