OpenTelemetry (OTel)

OpenTelemetry (OTel) is an open, vendor-neutral standard for generating and collecting telemetry — traces, metrics, and logs — from your applications. Instead of wiring your code to one monitoring vendor's SDK, you instrument once against OpenTelemetry and export the data to any backend that supports it: Datadog, Grafana, Honeycomb, or an open-source stack. That indirection is the whole point. It breaks vendor lock-in, so switching or comparing observability tools no longer means re-instrumenting your entire codebase. For SaaS builders this is a strategic hedge: your telemetry pipeline outlives any single tool contract. It's now a CNCF project with broad language support and auto-instrumentation for common frameworks. Practical note: adopt the OTel Collector as a central pipeline early, even if you only send data to one backend today — it gives you a single place to route, sample, and enrich telemetry, and turns a future vendor switch into a config change rather than a migration project across every service you run.
