Endigest AI Core Summary
Airbnb explains how they rebuilt their Observability as Code (OaC) alert development workflow to eliminate weeks-long validation cycles.
•Alert validation previously required deploying alerts to production and waiting for real-world data, creating cycles of weeks before confidence was possible.
•They built a local-first development platform where the same code runs identically on a developer's laptop, in CI, and in production.
•Phase 1 introduced markdown alert diffs with field-level granularity posted directly to PRs, eliminating error-prone copy-pasting.
•Phase 2 added a Change Report UI showing side-by-side alert diffs exactly as they appear in production.
•Phase 3 introduced bulk backtesting against historical data using Prometheus's rule manager, surfacing noisiness metrics and firing timelines.
•The platform enabled migration of 300,000 alerts from a vendor to Prometheus, compressing development cycles from weeks to minutes.
