A system that spans continents produces telemetry that spans legal jurisdictions. Here's how to keep traces and logs where the law wants them, and still see your whole system.

Every team has a tagging standard. Most of them live in a wiki, enforced by nobody, remembered by almost nobody, and invisible to the CI pipeline. Open Policy Agent fixes the root cause.

An audit trail is not a log. It's a tamper-evident, time-ordered record of who did what, when, and why. Most teams build this wrong. Here is how to do it correctly using OpenTelemetry and append-only storage.

Regulated industries need observability too. A guide to building telemetry pipelines that satisfy GDPR, HIPAA, SOC 2, and PCI DSS requirements — covering data minimisation, retention mandates, audit trails, and what each framework actually requires.
